The fire incident that occurred at Luton Airport's car park stirred considerable speculation online regarding the involvement of an electric or hybrid vehicle. It's important to note that no concrete evidence supports this assumption. According to Bedfordshire's chief fire officer, the fire is believed to have originated with a diesel vehicle, although this has not been officially confirmed.
As the sales of electric and hybrid cars continue to rise while registrations for traditional petrol and diesel vehicles decline, it is unsurprising that there has been an increase in reported cases of electric vehicle (EV) fires in recent years. Consequently, public concern regarding the safety of electrified vehicles has grown significantly in recent months.

But the question remains: Are EV’s more prone to fires compared to traditional petrol and diesel cars? Are they more challenging to extinguish? How have emergency services adapted their strategies to address EV fires? In this exploration, we delve into the data to seek answers to these questions.
Are Electric and Hybrid Vehicles at Greater Fire Risk than Conventional Petrol and Diesel Cars? Examining the Statistics
Are EV’s More Likely to Catch Fire Than Petrol and Diesel Vehicles? Research conducted by EV FireSafe, a private company supported by seed funding from the Australian Department of Defence to investigate EV battery fires, indicates that between 2010 and 2020, there was a minimal 0.0012 percent chance of passenger EVs catching fire globally.
However, when comparing this statistic to internal combustion engine (ICE) passenger vehicles globally, it's challenging to find an equivalent figure. Nonetheless, data from various countries suggests that there is approximately a 0.1 percent chance of petrol and diesel cars catching fire.
Tesla, a prominent global seller of EV’s with an 18.2 percent market share in 2022, claims that its cars are less likely to catch fire compared to ICE vehicles. Their 2020 Impact Report states that from 2012 to 2020, there was approximately one Tesla vehicle fire for every 205 million miles traveled. In contrast, data from the National Fire Protection Association (NFPA) and US Department of Transportation indicates that in the US, there is one vehicle fire for every 19 million miles traveled.
Some reports suggest variations between electric and hybrid vehicles and ICE cars. An analysis by AutoInsuranceEZ in the US, using domestic statistics from the National Transport Safety Board, the Bureau of Transport Statistics, and Vehicle Recalls in 2020, found that hybrid fires per 100,000 sales were more common than those of petrol and diesel models. However, this report did not differentiate between self-charging and plug-in hybrid cars. According to their findings, EVs ranked third on the list, with 25 fires per 100,000 sales.
In May, the Swedish Civil Contingencies Agency (MSB) suggested that EVs were 20 times less likely to catch fire than petrol and diesel cars, based on incidents recorded in Sweden in the previous year. The report noted 106 fires in various electric means of transport in Sweden in 2022, with only 23 of these fires occurring in EVs. This accounted for just 0.004 percent of Sweden's fleet of 611,000 EVs. In contrast, during the same period, approximately 3,400 fires were reported in Sweden from the country's 4.4 million petrol and diesel cars, accounting for 0.08 percent of that fleet.
While several studies suggest that the likelihood of EV’s catching fire is lower than that of ICE cars, there have been reports of an increase in EV fire incidents in the UK. Health and Safety organization CE Safety reported that between 2017 and 2021, there were 753 emergency service callouts for EV fires in the UK. While recorded EV fires remained relatively low, there was an upsurge in incidents in 2021. For example, the London Fire Brigade reported 32 fires in 2020, which surged to 102 in 2021. In the first half of the following year, 98 incidents were recorded. It's essential to note that these figures encompass all types of electric modes of transport, with only 210 out of the 753 cases being related to cars, alongside 110 e-bikes and 62 e-scooters.
A recent freedom of information request to fire and rescue services, published last month, revealed that between July 2022 and June 2023, these services attended 239 instances of fires related to EV’s in the UK. This marked an 83 percent increase compared to the 130 recorded between July 2021 and June 2022. These figures also encompass various electric vehicles, including electric scooters, trucks, and e-bikes, making it challenging to determine whether the increase is due to unsafe technology or simply a higher number of battery-powered vehicles on the road.
The president of Honeywell Sensing and Safety Technologies (SST), Sarah Martin, emphasized the need for effective lithium-ion battery safety technology in response to the rising number of EV-related fires. Although there is a noticeable increase in these incidents, the number remains low relative to the total number of EV’s in use across the UK, exceeding 1.1 million. Nevertheless, ensuring the safety of EV batteries is crucial as the adoption of these vehicles continues to grow.
Understanding the Challenge of 'Thermal Runaway'
Experts often highlight the term "thermal runaway" when discussing the risks associated with fires in battery-powered technology, including EVs. This phenomenon refers to a chain reaction within a battery cell that becomes extremely difficult to control once initiated by extreme heat, leading to a chemical reaction within the battery.
Triggers for thermal runaway can include overcharging, which has caused some devices to self-combust during charging, as well as collisions—a critical concern for electric vehicles. This reaction generates additional heat, increasing battery temperature and potentially triggering further reactions that prolong the duration of fires.
Thermal runaway can occur within milliseconds and can reach temperatures as high as 752 degrees Fahrenheit (400 degrees Celsius). According to the National Fire Chiefs Council (NFCC), thermal runaway can also result in unpredictable fire behavior, with ignition potentially occurring spontaneously over varying timeframes.
How Do EV Fires Differ from Petrol and Diesel Fires? While data supports the claim that EV’s are less likely to catch fire than petrol and diesel cars, they present unique challenges when it comes to firefighting. The key distinction lies in the high temperature and rapid combustion of lithium-ion batteries in EV’s.
EV batteries burn at a high temperature and require more effort to extinguish. They can generate enough heat to reignite after the initial fire has been put out, resulting in dormant phases that can last for hours before reigniting. This makes them extremely challenging to extinguish. Additionally, the high temperatures can lead to battery gassing and extremely hot blazes that are difficult to control.
The presence of reactive metals, such as lithium, in EV batteries can also release explosive and toxic gases and alkaline solutions when exposed to water. These gases, including carbon monoxide and hydrogen cyanide, can pose serious health risks to firefighters and anyone nearby.
The Difficulties of Extinguishing EV Fires According to Paul Christensen, a professor of Pure and Applied Electrochemistry at Newcastle University's School of Engineering, who is a leading expert on EV fires involving lithium-ion batteries, extinguishing electric vehicle fires is exceptionally challenging. He explained that getting water to where it's needed in an EV fire is a significant problem. EV battery cells are enclosed within a metal case, typically situated

As EV adoption has gathered pace, the number of EV batteries in the world has rapidly increased. But what will automotive OEM’s do with the batteries at the end of these vehicles’ lives?
Alex Charr, Chief Operating Officer at Connected Energy, explains how they can be monetised in second life energy storage applications.
Why are these batteries still useful?
An EV relies on its batteries for range, but when batteries degrade past a certain point, they can become less useful in a vehicle. Most vehicle manufacturers will replace their batteries when they still have 80% of their capacity remaining. So, at that point they have the options to dispose, recycle or reuse them. To me the choice is obvious.
That remaining capacity is perfectly suited to the less demanding applications of stationary energy storage. As we move to a world powered by renewable sources, which are often intermittent by nature, battery energy storage is going to play an increasingly important role in the energy mix. Storing green energy when it’s in abundance and releasing it when it’s not.
By aggregating multiple batteries and re-purposing them as an energy store, we’ve found the perfect solution to extend their lives, minimising the environmental impact of battery production and turning them into an asset rather than a problem that needs to be solved.
Why has finding a second life suddenly become so important?
It’s taken a little bit of time to get to this point. Until recently, the day-to-day focus for OEMs was on delivering the vehicles and looking at developing the second generation using better batteries. Second life was not a top priority for OEMs as they knew that the vehicle's end of life was years away.
More recently as the first generation of vehicles began to reach their end of life, we started to see much stronger engagement with companies as they started to see batteries from end-of-life EVs become available. No one wants to end up with warehouses full of batteries that become a liability when they could be a vital resource.
The clock is ticking already. By 2030 global management consultancy McKinsey and Co estimate that the second life lithium-ion battery supply could surpass 200 gigawatt-hours per year. So, you can see that this is going to present a real challenge for the industry. They also forecast that this volume will surpass the market size of utility-scale battery energy storage by 2030 – so a second life use case as battery energy storage is an obvious solution.
It is important that all OEM’s start engaging with second life experts like Connected Energy now, to explore the best options for second life applications. In this way, we all benefit – the auto industry, the fleet operator, the energy consumer and ultimately the planet.
Which OEM’s are looking at second life applications?
Renault was the pioneer in this space – driven by two major elements – the fact that they were so early to market but also in part by their unique business model. Initially, the manufacturer leased most of the batteries for its EVs, so as a consumer, if you bought a Zoe or a Kangoo, you were buying the vehicle but leasing the battery from Renault.
As these batteries reached the end of their life in a vehicle, these batteries were returned directly to Renault – and the manufacturer had the foresight to view these as assets. The company put in place a strategy to address the continued use of their batteries with the vision to reduce a battery’s carbon footprint and reuse them to play a pivotal role in the step towards a net zero carbon energy system.
Other OEM’s are now starting to look very seriously at second life. Volvo Energy, for example, has recently announced its ambition to jointly develop second life systems with our company. They are driven by creating a circular business model for their batteries. And this will become more pressing for all OEMs as new EU legislation puts greater responsibility on them to ensure that batteries are dealt with responsibly at vehicle end of life. Presently recycling is quite expensive, so flipping that by monetising those batteries in second life applications is becoming more and more attractive.
How will former EV batteries find their way into second life?
This is where the power of partnerships comes in. Connected Energy has built up strong relationships with many OEM’s over time, and continues to do so, opening the door to conversations about the possibilities of reusing vehicle batteries.
But it is still challenging and more needs to be done to track EV batteries through their life. To make this work, companies like ours need to have access to accurate data on battery health throughout the vehicle’s period of service. But once a passenger car or van leaves the forecourt, it could go anywhere – many will make it into the second-hand market and then what?
What is needed is organisations that act as the filter at end of life. They would aggregate the batteries, test and grade them. The ones which are no good can go to recycling and the rest can go into second life applications. We need that framework in place, an operational model that makes it easy to gather and grade those batteries to create a robust supply chain for second life pioneers like us.
What more needs to happen?
A major step forward will be the introduction of battery passports which will come into play in 2027. Battery passports will provide companies like ours with more transparent information on battery composition, performance and health throughout its life and at the end of life.
But if we are serious about the circular economy then there should also be government financial incentives or tax credits to nudge people towards buying second life energy storage systems instead of first life systems.
Second life energy storage is an early-stage technology and needs some support to kickstart the market. This is where governments need to come in. It’s happened before in the early stages of the wind and solar industries – with incentives that helped make the technology financially viable. This needs to happen again, with governments reducing the financial risk and thereby making second life more attractive.
The rise of electric vehicles has heralded a new era in transportation. As the world grapples with the urgent need to combat climate change, and most people just want to breathe cleaner air, EV’s offer a promising solution to reduce carbon emissions.
However, as with any technological shift, there are new habits and practices to adopt. One such practice revolves around charging. Should you wait for your EV's battery to run low before charging it fully, or should you top it up whenever you get a chance? This article delves deep into the advantages of the latter, using the example of shopping.

Self-driving cars were once the stuff of science fiction, but in recent years they have rapidly become a reality cruising on roads around the world. Over 20 million miles have been logged by autonomous test vehicles like those from Waymo. Yet only 14% of people report they would feel safe riding in one today based on a recent survey. This gap reveals the remaining challenges to be addressed before fully autonomous vehicles can reach their potential.
This article will examine the evolution of autonomous vehicle technology, from early research efforts to current capabilities leveraging AI and sensors. It will look at the major players pushing boundaries in this space, while also highlighting the roadblocks—from regulations to public trust—that must still be navigated on the way to wide adoption. Key impacts on urban infrastructure, transit systems, business models and more will be explored.
The aim is to provide a comprehensive look at the driverless future unfolding before us.
TL;DR
Autonomous vehicles have made significant strides in recent years thanks to advances in AI, sensors, and testing.
While companies like Waymo and Tesla push the boundaries of automation, challenges remain around handling complex driving scenarios, regulations, and public trust.
These self-driving cars have the potential to reshape cities by reducing traffic and parking needs if consumer confidence and legal frameworks evolve. But fully autonomous Level 5 vehicles are still a work in progress requiring rigorous safety evaluation before wide adoption.
For now, assisted driving features are helping pave the way for the driverless future.
For everyone else, there is a lot of detail to follow….
Brief History: Milestones in the Evolution of Autonomous Vehicles
The journey towards autonomous vehicles has been a long and winding road, marked by significant milestones that have shaped the industry. The first DARPA (Defense Advanced Research Projects Agency) Grand Challenge took place in 2004, acting as a catalyst for the development of autonomous driving technology. Although no vehicle successfully completed the course, the event was a watershed moment, sparking interest and investment in the field.
In 2007, the DARPA Urban Challenge saw a shift from desert terrains to simulated urban environments, and Carnegie Mellon University's "Boss" vehicle emerged victorious. This event demonstrated the potential for autonomous vehicles to navigate more complex settings, laying the groundwork for future research and development.
Google's self-driving car project, which later became Waymo, was officially launched in 2009. By 2015, Waymo had already logged over a million autonomous miles on public roads, a significant achievement that set the stage for other companies to enter the fray.

Tesla introduced its Autopilot feature in 2015, offering advanced driver-assistance capabilities but stopping short of full autonomy. While not a fully autonomous system, Tesla's Autopilot has been one of the most widely used and discussed features, pushing the conversation about self-driving technology into the mainstream.
Uber made headlines in 2016 when it launched its first self-driving car service in Pittsburgh. Although the service required a human safety driver, it marked a significant step towards the commercialisation of autonomous vehicles.
These milestones represent just a few of the key moments and players that have shaped the evolution of autonomous vehicle technology. Each has contributed to the advancements we see today, setting the stage for a future where autonomous vehicles could become a common part of our daily lives.
Current State of Technology: Understanding Levels of Automation
The autonomous vehicle landscape is often categorised into different levels of driving automation, ranging from Level 0 to Level 5. These levels serve as a useful framework for understanding the capabilities and limitations of today's autonomous vehicles.
Level 0: No Automation
At this level, all driving tasks are performed by the human driver. There are no systems in place to assist with driving; the driver is entirely in control. For example, a vintage car without any modern driving aids would fall under Level 0.
Level 1: Driver Assistance
In Level 1, a single driving task, such as steering or accelerating, can be assisted by the system. However, the human driver must remain engaged and monitor the environment at all times. Adaptive cruise control, where the car can adjust its speed based on the traffic ahead, is an example of Level 1 automation.
Here, the vehicle can manage both steering and acceleration but still requires the human driver to remain attentive and take over when needed. Tesla's Autopilot is a well-known example of Level 2 automation. Some jurisdictions, like California, have approved the testing of Level 2 systems on public roads.
Level 3: Conditional Automation
At Level 3, the vehicle can handle all driving tasks in certain conditions without human intervention but will request human assistance when it encounters a situation it can't handle. Mercedes-Benz Drive Pilot system, which can navigate through traffic jams without human intervention, is an example of this and has become the first manufacturer to get approval in Germany and the state of Nevada in the U.S.
Level 4: High-Level Automation
Vehicles at this level can perform all driving tasks in specific scenarios, like urban environments, without any human intervention. Waymo's autonomous taxi service in Phoenix, Arizona, operates at Level 4 and doesn't require a safety driver.
Level 5: Full Automation
This is the ultimate goal for autonomous vehicle technology, where the car is fully capable of handling all driving tasks in all conditions without human intervention. No steering wheel or pedals are needed. As of now, Level 5 has not been achieved or approved for public use anywhere in the world.
Understanding these levels of automation provides a clearer picture of where we currently stand in the journey towards fully autonomous vehicles. It also helps to set expectations for what is realistically achievable in the near term.
Sensors: The Eyes and Ears of Autonomous Vehicles
Image - NYT
Sensors play a pivotal role in the functioning of autonomous vehicles, enabling them to perceive and understand their environment. These sensors range from cameras and radar to lidar and ultrasonic sensors, each serving a unique purpose.
Cameras
Cameras are the most straightforward sensors, capturing visual data much like the human eye. They are essential for tasks like reading road signs, detecting traffic lights, and identifying pedestrians. Advanced algorithms process this visual data to make sense of the car's surroundings.
Radar
Radar (Radio Detection and Ranging) uses radio waves to determine the distance, speed, and direction of objects. It's particularly useful for detecting large metal objects like cars and is less affected by weather conditions compared to cameras.
Lidar
Lidar (Light Detection and Ranging) is one of the most fascinating sensor technologies in autonomous vehicles. It uses laser beams to send out pulses of light that bounce back upon hitting an object. By measuring the time it takes for the light to return, the system can calculate the distance to the object. Multiple lasers rotate to create a 360-degree field of view, building a detailed 3D map of the environment. This is crucial for tasks like obstacle detection and navigation.
These sensors use sound waves to detect objects, particularly useful for low-speed manoeuvres like parking. They emit ultrasonic waves, and if these waves hit an object, they bounce back. The sensor then calculates the distance based on the time it takes for the echo to return.
Experimental Sensors
Research is ongoing to develop new types of sensors that can further enhance the capabilities of autonomous vehicles. For instance, some companies are exploring the use of thermal cameras that can detect living beings based on heat signatures, which could be particularly useful for night driving. Another area of research is ground-penetrating radar, which could help vehicles understand road conditions below the surface, such as the presence of ice or water.

Understanding the intricacies of these sensors provides valuable insight into how autonomous vehicles perceive the world around them. As sensor technology continues to evolve, we can expect even more accurate and reliable systems in the future.
Artificial Intelligence: The Brain Behind Autonomous Driving
Artificial Intelligence (AI) serves as the computational brain of autonomous vehicles, making them capable of learning from data and making decisions in real-time. One of the key technologies underpinning AI in self-driving cars is machine learning.
How Machine Learning Works
In the context of autonomous vehicles, machine learning algorithms use data gathered from various sensors to learn how to perform driving tasks. These algorithms are trained on vast datasets that include different driving conditions, road types, and obstacles. Over time, the system becomes more adept at understanding its environment and making safe and efficient driving decisions. Essentially, the more data it processes, the smarter it gets.

Driving Tasks Automated by AI
One common driving task that AI helps automate is lane-keeping. Using data from cameras and other sensors, the AI system identifies lane markings and the position of the vehicle within them. If the vehicle starts to drift out of its lane, the AI system can automatically steer it back into the centre of the lane. This not only enhances safety but also reduces the burden on the human driver, if one is present.
AI's role in autonomous vehicles is not just limited to basic tasks; it extends to complex decision-making in real-time. Whether it's navigating through a busy intersection, avoiding a pedestrian, or deciding when to change lanes on a motorway, AI algorithms are at the heart of these operations.

Safety and Testing: Rigorous Measures to Ensure Roadworthiness
Ensuring the safety of autonomous vehicles is a paramount concern for all stakeholders involved. The testing process is rigorous and multi-faceted, involving both real-world driving and simulated scenarios. Here's a closer look at the extensive safety measures and testing protocols in place.
Extensive Road Testing
Companies like Waymo have clocked over 20 million miles of real-world driving to test their autonomous systems. These tests are conducted in various environmental conditions, including night-time driving, heavy traffic, and inclement weather, to ensure that the technology can handle a wide range of situations.
In addition to real-world testing, companies also use simulation software to put their autonomous systems through a multitude of scenarios that might be too dangerous or rare to test on public roads. Waymo, for instance, has run its software through more than 10 billion miles of simulated driving, testing thousands of unique scenarios, from avoiding pedestrians to navigating through complex intersections.
Independent Testing and Regulatory Oversight
Several independent bodies and regulatory agencies are also involved in the testing process. In the United States, the National Highway Traffic Safety Administration (NHTSA) has been actively involved in setting guidelines and conducting independent tests on autonomous vehicle systems. In the UK, the Centre for Connected and Autonomous Vehicles (CCAV) collaborates with industry players to ensure that the technology meets stringent safety standards.
Euro NCAP's Role
In Europe, the European New Car Assessment Programme (Euro NCAP) has started to include autonomous driving features in its safety ratings. This not only provides consumers with valuable information but also pushes manufacturers to meet high safety standards.
Safety Driver Involvement
During the testing phase, most companies employ safety drivers who are trained to take over control of the vehicle in case the autonomous system fails or encounters a scenario it can't handle. This adds an extra layer of safety during the development stage.
Transparency and Data Sharing
Some companies are also transparent about their safety testing protocols and results. They share this data with regulatory bodies and the public to build trust and to contribute to the collective understanding of autonomous vehicle safety.
Through extensive testing, both in the real world and in simulations, and through collaboration with independent regulatory bodies, the autonomous vehicle industry is taking comprehensive steps to ensure the safety and reliability of its technology.
Challenges: The Roadblocks to Full Autonomy
While the progress in autonomous vehicle technology has been remarkable, there are still several challenges that need to be addressed before we see fully autonomous cars on our roads. Below are some of the key challenges, along with recent breakthroughs that are helping to overcome them.
Inclement Weather Conditions
One of the most significant challenges for autonomous vehicles is operating in adverse weather conditions like fog, heavy rain, or snow. These conditions can severely impact the performance of sensors like cameras and lidar. For example, snow can cover road markings and signs, making it difficult for the vehicle's vision systems to navigate.
Another challenge is the unpredictability of human drivers, pedestrians, and cyclists. Autonomous systems are programmed to follow traffic rules to the letter, but humans often don't. This creates scenarios that are difficult for the AI to predict or understand, such as jaywalking or sudden lane changes without signalling.
Recent Breakthrough:
Machine learning algorithms are becoming increasingly sophisticated at predicting human behaviour. By analysing vast amounts of data, these systems can learn to anticipate and react to erratic human actions more effectively.
The legal landscape for autonomous vehicles is still very much in development. Questions around liability in the event of an accident, data privacy, and even ethical considerations (like how a car should react in a no-win scenario) are still being debated.
Recent Breakthrough:
Several jurisdictions are starting to develop and implement regulatory frameworks specifically for autonomous vehicles. In the UK, the Law Commission is working on legal frameworks that could govern self-driving cars, including questions of liability and insurance.
By understanding and addressing these challenges head-on, the industry is making steady progress towards making fully autonomous vehicles a reality. Advances in technology and regulatory frameworks are helping to mitigate these issues, but there's still work to be done.
Public Perceptions: Trust and Concerns in Autonomous Vehicles
Public perception is a crucial factor in the widespread adoption of autonomous vehicles. Despite the technological advancements, many people still have reservations about the safety and reliability of self-driving cars. Here's a look at some of the data that sheds light on these perceptions.
Survey Data on Consumer Attitudes
According to a 2021 survey by the American Automobile Association (AAA), only 14% of U.S. drivers would trust riding in a fully autonomous vehicle. This lack of trust is a significant hurdle for the industry to overcome. On the flip side, a more recent survey conducted in the UK in 2022 showed that 32% of respondents were open to using autonomous vehicles, indicating a gradual shift in public opinion.
Accident Rates: Autonomous vs. Manual Driving
When it comes to safety, the data is increasingly in favour of autonomous vehicles. According to the National Highway Traffic Safety Administration (NHTSA), human error is responsible for approximately 94% of all road accidents. In contrast, Waymo reported in 2020 that its autonomous vehicles had been involved in only 18 minor accidents during more than 20 million miles of testing on public roads, none of which were the fault of the self-driving car.
By presenting these statistics and continuing to improve the safety features of autonomous vehicles, the industry hopes to shift public perceptions more positively. However, it's clear that there's still a long way to go in winning over public trust.
The Future: Transforming Cities and Overcoming Regulatory Hurdles
The potential impact of autonomous vehicles on society is enormous, and it extends far beyond individual convenience. Here's a closer look at how these self-driving machines could reshape our cities and the regulatory challenges that still need to be addressed.
Reshaping Urban Infrastructure
Parking
One of the most immediate impacts of autonomous vehicles could be on parking. Self-driving cars don't need to be parked close to a driver's final destination; they can drop passengers off and then proceed to park themselves in a more remote location. This could drastically reduce the need for parking spaces in city centres, freeing up valuable land for other uses like green spaces or housing.
Traffic Flow
Autonomous vehicles have the potential to significantly improve traffic flow. With their advanced sensors and algorithms, these vehicles can maintain optimal speeds and avoid sudden stops, reducing traffic congestion. Some studies suggest that widespread adoption of autonomous vehicles could reduce traffic jams by up to 40%.
Regulatory Hurdles
Despite the promise, there are still several regulatory challenges to overcome. One of the most significant is the establishment of a legal framework for liability in the event of an accident involving an autonomous vehicle. Who is responsible—the owner, the manufacturer, or the software provider?
Another issue is the standardisation of vehicle-to-vehicle communication protocols. For autonomous vehicles to operate safely and efficiently, there needs to be a universal language for vehicle communication, something that is still in the works.
Moreover, there are concerns about data privacy and cybersecurity. Regulatory bodies are yet to establish comprehensive guidelines to protect the enormous amount of data these vehicles will generate and store.
Key Takeaways
Autonomous vehicle technology has progressed rapidly in the past decade, going from research projects to cars driving millions of test miles.
Using a mix of sensors and AI software, autonomous vehicles can now handle some driving tasks, but full self-driving remains complex.
Companies like Waymo, GM Cruise, and Tesla are leading innovations in autonomous driving technology.
Extensive real-world testing and simulation is being used to improve safety before autonomous vehicles are deployed at scale.
Fully self-driving Level 5 vehicles are not yet approved for complete autonomy anywhere due to remaining technical and regulatory challenges.
Public skepticism about safety and liability issues remains high, requiring trust building through transparency.
If deployed safely, autonomous vehicles could profoundly transform urban environments, mobility, transit systems and business models in the future.
But unlocking the full benefits will require addressing complex ethical, legal, infrastructure and access issues collaboratively.
The path ahead still has uncertainties, but the momentum and rate of progress make autonomous vehicles an exciting space to watch.
The Road Ahead: An Exciting Yet Uncertain Journey
The development of autonomous vehicles represents a truly remarkable revolution in transportation and mobility. In just a decade, self-driving cars have gone from sci-fi fantasy to complex machines cruising on public roads. But this technology remains in its adolescence, with progress measured in gradual evolution rather than overnight transformation.
While the promise is immense, the industry still faces a winding and uncertain path ahead. As the history shows, pioneering breakthroughs must continue in AI, sensors, and testing to handle the infinite variables of chaotic urban driving. Public skepticism and concerns around safety persist as well, requiring transparency and concerted outreach. And the regulatory systems to enable autonomous networks remain incomplete, an complex challenge crossing borders and industries.
The companies steering this autonomous revolution have demonstrated impressive technological achievements. But the final mile will likely require expanded collaboration across the public and private sectors to address the immense ethical, legal, social, and infrastructure questions arising. Cities must proactively plan for potential disruption to transit, parking systems, urban design, emergency services, and access for the disabled. And societies must grapple with how to distribute both the risks and rewards of automation equitably.
Autonomous vehicles undeniably represent a transformative force with the potential to profoundly reshape our cities, economies, and lives. The road ahead will have unpredictable twists and turns. But by embracing a culture of openness, collaboration, and foresight, society can steer towards an optimistic driverless future. The journey promises to be as fascinating as the final destination.

The brand's dominance is further reflected in its market share, customer satisfaction ratings, and the growing Tesla community in Australia. The recent shipment of 749 vehicles to Western Australia is a testament to Tesla's strong foothold in the region.
Government Subsidies and Price Drop
The Western Australian government has been supportive of the transition to electric vehicles. A $3,500 rebate was introduced in 2022 and is available for the next 10,000 new EVs sold in the state. These subsidies for eligible EVs have made Tesla's offerings more appealing to consumers in the state and are part of a broader initiative to reduce emissions and promote sustainable transportation.
In addition to government support, Tesla itself has made strategic price adjustments. The $3,500 price drop across multiple variants of the Model Y and Model 3 in the third quarter of 2023 has made these vehicles more accessible to a wider audience. This follows a previous price drop of around $3,000 in April 2023.
These price reductions, coupled with government incentives, have created a favourable environment for potential EV buyers. The combined effect of subsidies and price drops has likely contributed to the surge in Tesla sales and the record shipment to Western Australia.
Expansion of Charging Infrastructure
Tesla's expansion of charging infrastructure in Western Australia is a vital component of its strategy to support the growing number of Tesla owners in the state. The opening of its fifth supercharger site, equipped with three 250 kW V3 superchargers, is a significant milestone.
But Tesla's charging network expansion goes beyond just Western Australia. Across the country, Tesla has been investing in building and upgrading Supercharger and Destination Charger locations. This network allows Tesla owners to travel long distances with ease, knowing that fast and convenient charging is available.
The company's focus on charging infrastructure also includes collaboration with local businesses and governments to ensure that charging is accessible in urban and rural areas alike. Tesla's commitment to expanding charging infrastructure reflects its holistic approach to promoting electric mobility, not just through vehicle sales but also by enhancing the overall ownership experience.
EV Adoption in Australia
The current state of electric vehicle (EV) adoption in Australia is gradually progressing, but it has been relatively slow compared to other countries.
Australia has lagged behind the rest of the world in terms of EV sales, with fewer than 4% of new cars being all-electric, compared to 9% globally and 15% in the United Kingdom. However, the number of electric vehicles on Australian roads has been increasing, with the figure expected to exceed 100,000 in the coming months.
The market share of electric vehicles varies dramatically by region in Australia. The Australian Capital Territory has shown the strongest market share, with almost 10% of all new cars bought in 2022 being electric.
There is growing demand for electric vehicles in Australia, with reports of electric vehicles often being sold out within hours of being made available to the market. Consumer perceptions toward EVs are also being studied, indicating a growing interest in electric vehicles among Australian consumers.
While Australians are starting to buy electric vehicles in larger numbers, there are challenges in installing chargers rapidly enough to meet the increasing demand[5]. The government and industry are working to address these infrastructure challenges to support the transition to electric vehicles.
Overall, while the adoption of electric vehicles in Australia has been relatively slow, there are signs of progress and increasing interest in EVs among both consumers and the government. Continued efforts to improve charging infrastructure, establish ambitious CO2 standards, and address supply and demand challenges will be crucial in accelerating the adoption of electric vehicles in Australia.
The Future
The arrival of 749 Tesla vehicles in Western Australia marks a major milestone for electric vehicle adoption in the state and across Australia. This record shipment, along with strategic moves by Tesla and supportive government policies, signals an accelerating transition to sustainable transportation locally.
Tesla's pricing adjustments, charging network growth, and diverse model lineup catering to Australian's needs provide a template for EV makers hoping to succeed in the market. Meanwhile, Western Australia's subsidies and emissions reduction targets encourage consumers to go electric.
With additional infrastructure investments, continued model diversity, and more affordable offerings across brands, EVs could rapidly go mainstream in Australia. As consumers realise the environmental and economic benefits of driving electric, EV sales growth may begin to mirror trends in Europe and China.
In the fast-paced realm of electric vehicles and cutting-edge technology, even industry leaders like Tesla can face unexpected challenges. May 2023 saw Tesla grappling with a significant data breach, shedding light on the vulnerabilities even the most tech-forward companies can encounter.
Tesla is built on data
As a pioneer of connected electric vehicles, Tesla relies deeply on data for product functionality and improvement. Their models generate vast troves of sensor, usage, and performance data that inform everything from Autopilot refinement to personalized user experiences. This data dependence has powered Tesla's innovation but also exposed vulnerabilities.
In 2019, Tesla fell prey to an external data breach resulting in employee personal information being compromised. While not catastrophic, it highlighted the growing cyber risks in the connected car industry. Automotive systems have become prime targets, with hacks growing in frequency and sophistication. Researchers have demonstrated vulnerabilities allowing vehicle functions to be remotely accessed and controlled.
Protecting the data flowing between millions of vehicles, owners, and internal systems presents a monumental challenge for automakers.
As cars transform into "computers on wheels," data security is no longer just an IT concern - it's a core product safety issue.
For industry leaders like Tesla at the bleeding edge of connectivity, any lapse can attract hackers keen to probe emerging technologies.

Most electric vehicle owners want to maximise their driving range. So fully charging the battery to 100% may seem like the best practice. However, regularly charging to full capacity can negatively impact battery life and safety over time. This article will explore the nuances of EV charging capacity in depth.
Here are some key takeaways:
Limit most charges to 80-90% for longevity, and utilise EV settings to cap levels.
Occasional full charges are fine for longer trips - just avoid making it a daily habit.
Adhere to manufacturer charging recommendations for battery warranty compliance.
Improving technology is progressively minimising any risks of 100% charging.
How Lithium-Ion Batteries Work
Modern electric vehicles predominantly use lithium-ion battery packs for energy storage and delivery. These have become the technology of choice due to their high energy density, efficiency, and relatively low self-discharge when not in use.
Lithium-ion batteries consist of two electrochemical cells - a positively charged cathode and negatively charged anode. Lithium ions flow between these two cells through an electrolyte solution. This flow of ions generates energy output.
The state of charge (SOC) represents the battery's current capacity. At 0% SOC, the anode holds the maximum lithium ions. At 100% SOC, the cathode has absorbed its maximum capacity of ions. The ions transfer from anode to cathode on discharge and back on charge.
Charge and Discharge Cycles
The cycle of charging and discharging the battery by moving ions back and forth is integral to its function. However, this process inevitably stresses the cell materials and leads to gradual permanent loss of capacity over hundreds or thousands of cycles - a phenomenon known as cell degradation.
Minimising cell degradation and extending longevity requires carefully managing charge levels and cycles. This is why repeatedly maxing out to 100% SOC can reduce battery life over time. The strain of consistently hitting maximum capacity accelerates degradation.
Potential Downsides of 100% Charging
While most modern electric vehicles have safeguards against catastrophic battery failures from overcharging, consistently topping up to 100% state of charge can impact performance and longevity:
Accelerated Cell Degradation
Pushing to the maximum capacity places strain on the cathode material. Solid deposits called plating can form on the anode at very high charge levels. This permanent material loss decreases cell capacity over time.
By mostly keeping charges to 80-90% SOC, you can minimise degradation effects and extend the battery's useful life significantly. Studies show capacity loss is reduced by 25-35% when avoiding full charges.
Loss of Regenerative Braking Efficiency
Many electric vehicles can recover some energy through regenerative braking systems. But with the battery topped off at 100% SOC, there is no room left to store this regained energy.
Image source - https://www.evup.com.au
Limiting peak charge level ensures you can maximise efficiency gains from the regenerative braking function.
Safety Concerns in Extreme Cases
Serious battery failures remain extremely rare in modern EVs. However, pushing to the upper SOC threshold does increase the tiny risk of thermal runaway over time.
Thermal runaway occurs when cell temperature rapidly self-accelerates from overheating, potentially leading to fire or explosion. But multiple safeguards in battery management systems prevent this.
While safety risks are minimal, the extra stress of 100% charging is best avoided as a precaution.
Battery Warranty Impacts
Some manufacturer warranties require adherence to charging guidelines for full coverage. For example, Nissan LEAF’s warranty states regularly charging over 80% SOC may void battery capacity guarantees.
Check your EV’s recommended charging practices to ensure you comply with any battery warranty terms. Staying safely under 100% is generally advised.
Optimal Charging Strategies
Given the potential downsides, what are the best charging practices to optimise your EV battery life?
Daily/Regular Charging to 80-90%
For day-to-day use, target charging to 80-90% state of charge. This provides substantial range for daily driving while minimising strain on the battery. Think of it as an EV version of not “running your tank dry.”
The last 10-20% capacity requires the most charge time and exerts the most pressure on cells. By consistently avoiding the high stress of 100% charging, you extend the battery’s longevity.
Utilise Manufacturer Charge Limit Settings
Many electric vehicles come equipped with software settings to limit the maximum state of charge. For example, a cap at 90% prevents overcharging while still providing some buffer for unexpected trips.
Consult your manufacturer's guidelines for optimising battery charge settings. Take advantage of technology built-in to your EV to automate healthy charging routines.
Consider Your Driving Needs
There are certainly times when you need to charge to 100% capacity to enable a longer trip. Occasional full charges are generally fine. It's the habit of constantly hitting 100% that can impact battery health over the long run.
If you know you have a long drive coming up, charge to 100% beforehand, then discharge a bit by running errands before your trip. Avoid parking at full capacity for prolonged periods.
Future Advances in Charging Tech
As charging networks expand, advances in battery chemistry, regenerative braking systems, and charging speed will help minimise capacity concerns. With ever-faster charging capabilities, there will be less need to charge beyond 80% for daily commuting.
Future EVs may even adapt based on your driving patterns and self-learn optimal charging levels for maximising battery longevity (similar to an iPhone). Continual improvements will further alleviate any minimal risks of charging to full capacity.
Finding the Optimal Balance for Your Needs
In summary, understanding your electric vehicle's battery characteristics and charging needs is key to finding the optimal balance. While regularly charging to 100% capacity can accelerate degradation, the limitations are often overstated, especially as technology continues improving.
By adopting smart charging routines and avoiding unnecessary strain on cells, most EV owners should see no significant battery life reduction with occasional full charges when required. Here are some final tips:
For daily use, target 80-90% charge to minimise battery wear - use manufacturer caps if available.
Plan ahead for longer trips and top up to 100% judiciously when needed. Discharge slightly before departing if possible.
Consider your actual driving habits and needs - don't over limit charge levels based on exaggerated risks.
Stay informed on advancing EV tech like fast charging that will continue minimising capacity concerns.
Refer to your owner's manual for optimal settings and charging recommendations to preserve warranties.
The future is bright for electric vehicle battery tech, promising ever-faster charging with minimised deterioration. Until then, be mindful of excessive 100% charging, but recognise current limitations are surmountable. Seek a balance between maximising range and longevity.
With smart charging habits and avoidance of unnecessary stress on cells, you can comfortably enjoy the benefits of electric driving knowing occasional full charges have a negligible effect.

For electric vehicle owners, understanding how to charge efficiently is key to saving time and maximising battery life. While it may seem logical to plug in and charge up fully in one go, a two-stop charging approach can often be a smarter strategy.
By stopping twice for shorter charging sessions at lower State of Charge (SoC), you can take advantage of faster charging speeds, align stops with your travel needs, reduce battery stress, and minimise range anxiety. Read on to learn how and why “two is better than one” when it comes to planning EV charging stops.
Key Takeaways
Two shorter charging stops can reduce total charging time compared to one long session.
Lower state of charge allows faster charging speed due to the battery charging curve.
Coordinating charging with your route and breaks adds convenience.
Moderate charging is healthier for batteries than frequent 100% top-ups.
EV Charging Basics
First, a quick primer on key EV charging terms:
SoC - State of Charge: The battery's current charge level shown as a percentage of full capacity. Your vehicle's "fuel gauge".
kWh - Kilowatt-hour: The unit of energy used to describe battery capacity and charging power.
Charging Levels: Level 1 uses a regular wall outlet for slow overnight charging. Level 2 uses a 240V outlet for faster few-hour charging. DC fast charging can add substantial range in under an hour.
An EV battery charges faster at a lower state of charge. Charging speed slows down progressively as the battery fills up. By stopping twice and charging at a lower SoC, you maximise time on the faster part of the charging curve.
For example, charging a Tesla from 20% to 60% SoC might take 15 minutes, while 60% to 100% may take 30 minutes at the same charger. Two 30-minute stops can put more energy into the battery than one 60-minute charge session.
Convenience and Route Planning
Coordinating charging stops with meal breaks or other stops makes the trip more convenient and enjoyable. Two stops also gives flexibility for route planning if needed.
Modern tools like Zap-Map make locating charging points convenient and even allow them to be incorporated into journey planning. With the growth in public networks, finding suitable stations for two-stop trips is increasingly viable.
Battery Health
Repeatedly fast charging to 100% SoC can accelerate battery degradation. Two shorter charges to lower peaks puts less sustained strain on the battery, potentially prolonging its lifespan.
Follow manufacturer guidance on maintaining battery health, including charge frequency and avoiding overcharging.
Overcoming Range Anxiety
Knowing charging stops align with your route limits range anxiety. If unplanned detours are needed, having less than a 100% full battery gives you the flexibility to top up as required.
Apps that incorporate chargers into navigation and provide real-time range estimates further alleviate worries over running out of charge mid-journey.
Practical Tips for Efficient Two-Stop Charging
Use trip planning apps to map out charging stops and destinations - Zap-Mapand Watts-Upare great!
Monitor SoC and target charging levels for maximum speed - often around 20-60% SoC.
Align stops with meal breaks or other needs.
Opt for chargers offering renewable energy sources when possible.
Adapting your EV charging strategy to utilise two stops at lower SoC can optimise efficiency, battery life, and trip enjoyment. Smarter charging through better awareness unlocks the full potential of electric vehicles.
As discussed, switching to two shorter charging stops at lower state of charge provides important benefits:
Quicker charging thanks to faster speeds when battery level is low.
Increased convenience by aligning stops with your trip needs.
Reduced battery strain compared to repeated 100% fast charges.
Less range anxiety knowing chargers fit your route.
While one-stop full charges may seem simpler, they often are not the most effective approach for time or battery health. Adopting a two-stop plan requires planning but pays off.
Use route tools to map optimal charging stop locations and distances.
Monitor the state of charge and exit charges before 100% when feasible.
Coordinate stops with meal or rest breaks to integrate both seamlessly.
Electric vehicles enable sustainable transportation, but smart charging unlocks their full potential. Equipped with knowledge on maximising efficiency in two shorter stops, EV owners can optimise their driving experience.
Smarter charging habits take awareness and preparation. But the benefits for you and your vehicle make it a worthwhile endeavour. By reconsidering one-stop full charges, you can embark on your electric journey knowing you have the power to go the distance.

Range anxiety is one of the most persistent fears holding drivers back from electric vehicle adoption. Despite major advances in EV technology, worries over running out of battery charge before reaching a destination stubbornly remain. This psychological hurdle stems from lack of familiarity with how modern EVs truly perform. By understanding range optimisation strategies, drivers can feel reassured that current electric vehicles offer more than enough capacity for their daily needs. This article will explore the realities behind EV range anxiety and how knowledge and preparation can conquer these outdated perceptions.
Is Range Anxiety in EVs Justified?
Thanks to continuous advances in EV battery technology over the past decade, range anxiety has become far less justified than in the early days of electric vehicles. The driving ranges of contemporary electric vehicles have increased dramatically compared to early EVs. For example, the 2023 Tesla Model 3 offers up to 358 miles on a single charge, a significant improvement over the early 2010s when sub-100 mile ranges were common.
In addition to extended range, the availability and speed of EV charging options is improving rapidly. The number of public charging locations in the UK has grown exponentially, providing more opportunities to top up when out and about. Battery charging technology enabling faster charging times has also helped minimise downtime when recharging on the go.
However, despite these advances, consumer perceptions haven't fully caught up. Range anxiety still prominently features in surveys of potential EV buyers as a top concern limiting adoption. So while the actual limitations are reducing, the psychological aspect of range anxiety persists.
What Factors Affect EV Range in Real-World Driving?
To gain full confidence in an electric vehicle, drivers should educate themselves on the factors that can impact its real-world range under different conditions:
Battery Size - The capacity of the battery pack (measured in kWh) determines range potential. Large batteries extend range but increase weight and cost.
Vehicle Weight - Heavier EVs use more power to accelerate, reducing efficiency and draining the battery faster. Lightness improves range.
Terrain and Topography - Hilly or mountainous driving requires more battery usage and decreases range. Flat terrain maximises range.
Driving Style - Aggressive acceleration and braking dramatically reduces efficiency compared to smooth and moderate driving.
Climate Controls - Heating, air conditioning, and heated seats divert battery energy from driving range. Minimising usage extends range.
External Temperature - Cold weather and extreme heat reduce battery efficiency and longevity, impacting range.
Vehicle Speed - Driving at motorway speeds compared to urban speeds consumes battery capacity faster, limiting range.
Auxiliary Systems - Headlights, sound systems, and other in-car electronics drain battery power that could go towards driving range.
Understanding how these variables impact the driving range of their specific EV model allows owners to make informed decisions about when and how to drive to optimise battery efficiency. This knowledge helps dispel uncertainty and the blind fear of unexpected drains on range.
Tools and Strategies to Alleviate Range Anxiety
EV technologies and charging infrastructure improvements have expanded to provide drivers with multiple avenues to maximise driving range and minimise interruptions to their journeys.
Sophisticated Range Estimation Tools
Modern electric vehicles are equipped with advanced sensors, mapping tools, and range estimation systems. These use driving patterns, topography, live traffic, climate control usage and other data to provide updated estimates of remaining range in real-time.
Watching estimated range fluctuate during a trip helps drivers better correlate driving variables to battery usage. Advanced regenerative braking systems also recapture energy while slowing down to extend range estimates.
Route Planning Around Charging Stations
In-car navigation systems and smartphone apps like Zap-Map allow EV drivers to plan routes that incorporate charging stops at intervals within their vehicle's range. This prevents range anxiety while in transit by ensuring drivers will pass convenient charging locations when needed.
Home and Workplace Charging
Installing wall chargers at home and/or work provides peace of mind by enabling drivers to start each day with a full battery. Having consistent charging eliminates concerns over public infrastructure availability.
Regular Charging Network Updates
Checking charger maps and staying current on new charging station installations along frequented routes keeps drivers confident in the growing public charging access.
Emerging Rapid Charging Technologies
New ultra-rapid charging systems can add hundreds of kilometres of range within 10-30 minutes. Battery-swapping stations can replace depleted packs with fully charged ones in seconds. These emerging technologies demonstrate the potential for virtually eliminating range limitations.
The Future of Range Anxiety in EVs
While range anxiety may persist among some demographic groups, predictions point towards it fading as a major barrier to mass EV adoption. Younger generations who have grown up with electric vehicles show minimal concerns over range limitations.
As battery densities continue to improve, charging rates accelerate, and charging stations proliferate, range anxiety will likely join "fuel anxiety" as a non-issue for most drivers in the not-too-distant future. In fact, the benefits of always starting each day with a "full tank" thanks to home charging may make range anxiety seem quaint.
The stage is set for driving electric to become the preferred choice for drivers across all vehicle segments. While outlying concerns over range hang on, innovative technologies and infrastructure developments are steadily liberating drivers from even having to think about miles between charges. The freedom of driving powered by electricity appears more certain than ever.
Conclusion
For those considering an electric vehicle, focusing on the actual capabilities of modern EV batteries, not outdated perceptions, shows that limitations of range are dissolving. Knowledge, preparation and embracing available tools for optimising range offer the confidence to make the switch.
As public awareness catches up to the new reality enabled by EV technological advancements, range anxiety will soon be an antiquated relic of the early electric vehicle era.

The increased reliance on combustion engine vans for these deliveries has led to a troubling surge in polluting emissions, exacerbating the persistent issue of air quality in urban areas.
The Rising Emissions from Delivery Vans
Over the past few decades, emissions from light goods vehicles have surged by a disconcerting 65% since 19901. This increase in emissions underscores a troubling reality: the delivery vans that bring us our goods are becoming major contributors to air pollution in our cities. In fact, these vans are now responsible for a staggering 14% of nitrogen oxide (NOx) emissions stemming from road transportation2. As we reflect on these statistics, it becomes clear that urgent action is needed to address the environmental impact of our evolving shopping habits.
A Complicated Focus: Passenger Vehicles vs. Commercial Fleets
Considering the above, An intriguing question arises:
Why has the focus primarily been on passenger vehicles, while the impact of commercial delivery vans remains a significant concern?
This query, though lacking a straightforward answer, prompts us to explore potential solutions to the complex challenges posed by commercial vehicle emissions.
In many ways, the hesitancy surrounding the mainstream adoption of electric vehicles by you and me applies even more intensely to fleet and van owners. The hurdles are magnified when we consider the specific needs and demands of commercial operations.
Charging Infrastructure Lags for Vans
One crucial factor in the slower adoption of electric vans is the need for a robust charging infrastructure to support widespread use. While progress has been made in establishing charging stations, particularly for personal vehicles, the infrastructure for larger commercial vans is reliant on the companies themselves and may not warrant the upfront cost to install and sustain an entire fleet of delivery vehicles. This, coupled with charging times for electric vans being notably longer than filling up with combustible fuel, can severely affect business bottom lines and total cost of ownership calculations.
Range and Payload Limitations
One other significant obstacle that everyone who has heard of an EV knows about is their “limited” driving range. Although new passenger EVs on the market now offer more than enough range, there is still a hypothesis in the commercial industry that electric vans don’t have enough range to cover substantial distances during delivery services. And this "range anxiety" can discourage businesses from transitioning to electric vans.
Additionally, the weight of batteries in electric vans affects the overall payload capacity, and the space required to accommodate these batteries and e-axles can further limit the cargo capacity, making electric vans less suitable for certain types of deliveries, or types of van such as ambulancesand minibuses which need to maximize their payload.
Navigating a Sustainable Future
The rise of home delivery services has undoubtedly reshaped our shopping habits, offering unparalleled convenience. However, the environmental consequences of this shift cannot be ignored. As we confront the pressing challenge of mitigating emissions from commercial delivery vans, it is imperative that stakeholders across industries collaborate to find innovative solutions
Governments must provide incentives and policies that support the adoption of electric vans, especially in commercial fleets. Alongside these incentives and policies, a rethink on whether full electric or hybrid is the way to go for vans can help overcome some of the logistical obstacles in the short to medium term.
Industry players must invest in advancing technology and creative solutions to enhance driving ranges and charging efficiency. Things like shared charging infrastructure, retrofitting and battery swapping are all on the table as solutions. For example, commercial vehicle manufacturer Iveco has launched an electric van that uses an easily swapped, cassette-style battery. Allowing users to retrospectively remove or add elements to the modular battery pack or swap in fully charged batteries, similar to the technique pioneered by NIO.
While the road ahead is undoubtedly complex, the urgency of reducing emissions from delivery vans is undeniable. By collectively striving for innovation, sustainable practices, and creative solutions, we can transform the convenience of home delivery, creating cleaner and healthier urban environments for generations to come and making the transition to electric vehicles both viable and attractive for fleet operators and managers.
With electric vehicles becoming more mainstream, understanding how to charge them is crucial. But not all charging is equal - AC and DC fast charging use different methods that impact charging speed, convenience and battery life. This guide will explain the key distinctions so you can charge your EV efficiently.
To understand the difference between AC and DC charging, it's important to cover the basics of alternating and direct current electricity. Alternating Current (AC) flows back and forth directionally and is used for most power grids and household supplies. Direct Current (DC) flows in a single direction and is used in batteries, solar panels, and EVs.
Why AC and DC?
AC and DC charging serve different needs. AC covers home and destination charging when you're parked for hours. DC enables ultra-fast charging on road trips with minimal downtime. Combining both optimizes daily charging and long-distance travel.
AC charging uses alternating current to charge an EV battery through an onboard charger. AC chargers range from 3-22kW and typically require several hours to provide a full charge. The lower power makes AC ideal for overnight home charging to fill up while you sleep. Public AC chargers also allow topping up at retail, leisure and hospitality settings as well as offices and other workplaces. AC charging uses alternating current electricity from the power grid. The onboard charger converts the AC supply into DC to charge the battery.
DC
What is DC Fast Charging?
DC fast charging converts the alternating current from the electrical grid into direct current offboard the vehicle. This DC supply can then rapidly charge the battery.
DC fast charging bypasses the onboard charger and sends direct current straight to the battery. DC chargers range from 25-350kW, enabling much faster charging. For example, a 150kW DC fast charger can add 100 miles of range in 15 minutes. However, the rapid power transfer causes more battery wear over time.
AC charging uses the onboard charger, DC fast charging converts power offboard before entering the EV.
AC charging provides 3-22kW, while DC fast charging offers 50-350kW for ultra-rapid charging.
It takes several hours to fully charge with AC, while DC can add a substantial range in under an hour.
AC is ideal for home and destination charging, and DC for rapid top-ups while travelling.
Excessive DC fast charging can degrade batteries faster than AC.
In summary, AC and DC charging work hand-in-hand. AC conveniently covers daily charging needs, while DC enables long trips with minimal downtime. Understanding the pros and cons of each allows EV owners to utilize both solutions and optimize the driving experience.

Upgrading to an electric vehicle (EV)? One key decision you'll need to make is whether to install a tethered or untethered AC charger in your home. While both types charge your EV's battery, they have distinct differences that impact convenience, flexibility and aesthetics. This guide examines the key factors to consider when deciding between tethered and untethered EV chargers for your needs.
AC charging in brief
AC (Alternating Current) EV charging refers to the use of alternating current to charge EVs.
Unlike DC (Direct Current) charging, which provides rapid charging, AC charging is typically slower and is commonly used for home or workplace charging.
AC chargers typically deliver between 3.6kW and 22kW per hour, filling a 50kW battery from 10% - 100% in 5-7 hours.
AC chargers deliver the Alternating Current from the grid into the vehicle, which is then converted by an onboard “rectifier” inside the vehicle into Direct Current that can be stored in the battery.
AC infrastructure is more cost-effective to deploy and widely available but takes longer to fully charge the vehicle.
AC charging is ideal for overnight charging or when the vehicle will be parked for an extended period.

Introduction to Tethered and Untethered Chargers
Tethered chargers have the charging cable permanently fixed to the EV charger. The cable is typically 6-10 feet (1.8-3M) long, allowing you to conveniently plug into the EV inlet without excessive slack.
Untethered chargers have a socket and provide the flexibility to plug in interchangeable cables as needed - similar to a socket in your home.
Both options deliver the safe, high-powered charging your EV requires. But understanding the unique pros and cons of each is essential to make the best choice for your home and driving habits.
Tethered EV Chargers: Convenience With Some Limitations
Tethered chargers offer simplicity and convenience thanks to their fixed, pre-connected cable. However, the permanence of the attached cable also introduces some potential limitations.
Convenience
The primary benefit of a tethered EV charger is the convenience factor. With the cable permanently affixed, charging takes seconds – simply plug into your vehicle and start charging. No need to unwind, arrange and reconnect a cable each time.
Aesthetics
Tethered chargers are often not as pleasing to the eye as untethered chargers because the cable will always be visible next to the charger when the charger isn’t being used. This makes it harder for the charger to blend into the exterior of the home.
Safety
With no removable cables or additional connections needed, tethered chargers eliminate physical strain or damage from handling cables. Their simplicity adds a degree of safety and reliability.
Limitations
However, the fixed cable also imposes some limitations. You must park closely enough for the attached cable to reach your EV inlet. This may not work for all parking configurations, limiting placement options.
The lack of flexibility also means you can't take the charger cable to another vehicle or location. And if the fixed cable sustains any damage, the entire unit will likely require replacement.

Untethered EV Chargers: Flexibility With Added Handling
In contrast to tethered chargers, untethered chargers feature removable, interchangeable cables that provide greater flexibility. However, they do require some additional physical handling during operation.
Flexibility
Untethered EV chargers give you complete freedom and flexibility to charge in different locations, move the cable out of the way when needed, or even charge a second vehicle with a different inlet type.
Their modular nature means if the cable sustains any damage, you can simply replace the cord while keeping the wall charger unit intact.
Since the cable disconnects, you aren't limited by a fixed length when parking. This provides more options for charger placement in your garage or drive as a longer cable can be used.
Handling
The main drawback of untethered chargers is the need to manually connect the cable each time you charge. Thicker cables can be heavy and challenging to manipulate.
Repeated handling also introduces risks of tripping, straining muscles, or damaging the cable over time through wear and tear or being driven over. Proper storage is essential to protect cables when not being used.
Key Differences and Considerations in Choosing
When deciding between tethered and untethered EV chargers, keep these key considerations in mind:
Parking Logistics - Does a fixed cable length work for your parking space or do you need flexibility?
Frequency of Use - Frequent charging makes tethered more convenient while occasional charging benefits from untethered flexibility.
Aesthetic Priorities – Untethered chargers offer a tidier, streamlined look.
Safety Concerns – Limiting handling and tripping hazards may be a priority.
Future Needs – A tethered cable is what it is. If you add an additional Ev in the future with a different inlet type this could cause an issue.
Find the Right Charger for Your Needs
For most homeowners, either a tethered or untethered charger will meet their EV charging needs. Thoughtfully weighing convenience, flexibility, aesthetics and safety based on your specific parking situation, usage frequency and future plans will ensure you select the optimal setup.
With a clear understanding of the pros and cons of each type, you can make an informed decision on the best EV charger for your home. Soon you'll be charging your electric vehicle safely and conveniently as you drive towards an electrified future.

The automotive industry is witnessing a paradigm shift with the rise of electric vehicles (EVs) and the introduction of hydrogen fuel cell vehicles (FCEVs). As the world grapples with climate change, the search for sustainable transportation solutions has never been more critical. This article will provide a comprehensive, unbiased (honestly!) comparison between Battery Electric Vehicles (BEVs) and Hydrogen Fuel Cell Vehicles, exploring their efficiency, infrastructure, costs, and sustainability impacts.
Key Takeaways:
Both BEVs and FCEVs can offer long ranges suitable for most driving, but rapid charging is far more accessible for BEVs currently.
Hydrogen fueling infrastructure lags far behind electric charging stations, creating a major adoption barrier for FCEVs.
BEVs demonstrate higher well-to-wheel efficiency, converting over 59% of electrical energy to power versus 25-30% for FCEVs.
Green hydrogen production methods are needed to reduce FCEV emissions but remain underdeveloped compared to BEVs charged by renewable energy.
While FCEVs face challenges, they may fill important niches like long-haul transportation that complement smaller passenger EVs.
Battery Electric Vehicles, or BEVs, operate using a battery pack that stores electricity, which powers an electric motor to drive the wheels. The battery is typically a lithium-ion type, known for its high energy density and long lifespan. The electric motor, power electronics, and battery work together to form the powertrain, converting electrical energy into mechanical energy.
Charging Methods and Expanding Charging Infrastructure
Charging a BEV is akin to charging a mobile phone. You plug it into a charger, and it refills the battery. There are various charging methods that charge at different speeds, including:
Slow Charging: Using a regular household plug, typically taking 8-12 hours for a full charge.
Fast Charging: Utilising dedicated charging stations either at home, work or other destinations, that can charge a battery to 80% in around 4-6 hours.
Rapid Charging: Utilising dedicated charging stations that can charge a battery to 80% in around 30 minutes.
Hydrogen Fuel Cell Vehicles (FCEVs) use a different approach to generate power. They utilise hydrogen gas, which is combined with oxygen in a fuel cell stack to produce electricity through a chemical reaction - not combustion. This chemical process produces electricity, as well as some heat and water as byproducts.
Specifically, hydrogen atoms are stripped of their electrons at the anode. The freed electrons travel through an external circuit creating an electric current to power motors or other devices.
Meanwhile, hydrogen's positively charged protons pass through a membrane to the cathode. At the cathode, the electrons reunite with the protons and oxygen atoms, producing water.
Fuel Cell Stack, Storage Tanks, Electric Powertrain
The fuel cell stack is the heart of an FCEV. It consists of many individual fuel cells that combine hydrogen and oxygen to produce electricity. The hydrogen is stored in high-pressure tanks, typically at 350-700 bar. Like BEVs, FCEVs also have an electric powertrain, including an electric motor and power electronics.
Refuelling Process and Hydrogen Supply Chain
Refuelling an FCEV is similar to refuelling a petrol car. It takes only a few minutes to fill the hydrogen tanks. However, the hydrogen supply chain is complex, involving production, transportation, and storage. Currently, most hydrogen is produced from natural gas, a process that emits carbon dioxide. There are also methods to produce hydrogen using renewable energy, known as green hydrogen, but these are still in the early stages of development.
Infrastructure and Logistics Comparison
The next section will delve into the differences in the maturity of charging station vs hydrogen fuelling station rollout, and examine the challenges related to hydrogen production, transport, and storage.
Charging Station vs Hydrogen Fuelling Station Rollout
The infrastructure for Electric Vehicles and Hydrogen Fuel Cell Vehicles is at different stages of development:
BEVs: The UK has a rapidly expanding network of charging stations, with over 25,000 public charging points, including fast-charging stations.
FCEVs: Hydrogen fuelling stations are less common, with around 15 publicly accessible stations in the UK as of 2021.
The disparity in infrastructure presents a challenge to the widespread adoption of FCEVs.
Hydrogen Production, Transport, and Storage Challenges

Production: Most hydrogen is produced from natural gas, a process that emits CO2. Green hydrogen production, using renewable energy, is still in its infancy.
Transport: Hydrogen is typically transported by road in high-pressure tanks or via pipelines, both of which are expensive and energy-intensive.
Storage: Storing hydrogen requires specialised tanks that can withstand high pressure, adding to the cost and complexity.
These challenges contribute to the current higher cost and lower availability of hydrogen fuel compared to electric charging.
Efficiency: BEVs are generally more efficient, converting about 59-62% of the electrical energy from the grid to power at the wheels. FCEVs convert about 25-30% of the energy in hydrogen to power at the wheels.
Range: Both BEVs and FCEVs offer ranges suitable for most daily driving needs, with some FCEVs offering slightly longer ranges.
Fuel Costs: Electricity for BEVs is generally cheaper than hydrogen for FCEVs, although this can vary based on location and energy prices.
Higher Upfront Costs for FCEVs Currently
FCEVs tend to have higher upfront costs compared to BEVs, mainly due to the expensive fuel cell technology. However, government incentives and subsidies may help offset some of these costs.
Thank you for reading The EV Feed. This post is public so feel free to share it.
FCEVs: If hydrogen is produced from natural gas, CO2 emissions occur. Green hydrogen production methods can reduce emissions, but they are still under development.
Environmental Concerns Around Hydrogen Production from Natural Gas
Producing hydrogen from natural gas, known as steam methane reforming, emits CO2. Efforts are being made to capture and store these emissions, but the technology is still emerging.
Although today most hydrogen is produced from natural gas, the Hydrogen and Fuel Cell Technologies Office is exploring a variety of ways to produce hydrogen from renewable resources. Image - energy.gov
The Road Ahead
Projections for Growth and Advancements for Each Technology
BEVs: The UK government has announced a ban on the sale of new petrol and diesel cars by 2030, with a focus on promoting electric vehicles. This policy is expected to drive significant growth in the BEV market.
FCEVs: Hydrogen fuel cell technology is still in the early stages of commercialisation. However, it's receiving attention as a potential solution for heavy-duty transport like buses and lorries, where BEVs may not be as suitable.
Challenges and Uncertainties Facing FCEVs in Competing with BEVs

Electric vehicles (EVs) are revolutionising the way we drive, offering a cleaner and more sustainable mode of transportation. But what happens when you have more than one EV in your household? Can you have two electric vehicle chargers at home? The answer is yes, but it's not as simple as it might seem. This comprehensive guide will delve into the various aspects of dual charging at home, focusing on the cost, space, charging speed, driving habits, vehicle inlet types, and alternative charging options.
Cost Implications of Dual Charging
Installing two electric vehicle chargers at home is an investment. On average, the cost for a single charger and its installation is approximately £1,000. So, for two chargers, you're looking at over £2,000. While this might seem steep, there are ways to cushion the cost:
EV Chargepoint Grant: If you live in a flat or rented accommodation, you might be eligible for this grant, which can subsidise one of the chargers by £350.
Finance Options: Spreading payments with finance is available on many home electric vehicle chargers, offering flexibility in payment.
The space available on your property plays a crucial role in the decision to install multiple chargers. If you have limited space, sticking to one electric vehicle charger might be the best option. However, if you have multiple garages or off-street parking, you might have room for two or more chargers. Assessing space and considering the aesthetics of your house is vital before making a decision.
Charging Speed
Charging speed is one of the most critical factors to consider when thinking about dual charging. Here's a detailed look at how the time it takes to charge can be affected:
Single-Phase vs Three-Phase Electricity Supply: Most UK households have a single-phase electricity supply. If you have two 7kW home EV chargers on one circuit with a single-phase supply, you'll be charging at approximately 3kW to 3.6kW each, rather than both at the typical 7kW. Upgrading to a three-phase electricity supply can solve this issue, but it's an expensive and time-consuming process.
Load Balancing Feature: Investing in home EV chargers with a load-balancing feature can ensure equal charging. The Easee One, for example, allows you to 'daisy chain' up to three electric vehicle chargers on your property per dedicated circuit. However, with a single-phase electricity supply, charging both EVs simultaneously will still result in a reduced charging speed of around 3kW each.
Dual Chargers: Dual chargers are one charging unit with two connectors. This might be a slightly cheaper option but it will still face the issue of decreased charging speed if both connectors have to share the supply from one circuit.
Understanding your charging needs, the type of electricity supply you have, and the features of the chargers you choose can help you make an informed decision about dual charging at home.
Your daily commute, the frequency of long journeys, and the typical range of your EV all play a role in determining whether two chargers are necessary. If every EV driver in your household has a long daily commute and a smaller battery, requiring frequent charging, two chargers might be beneficial. Conversely, if commutes are short or infrequent, one charger might suffice. It’s kind to share!
Vehicle Inlet Types: Compatibility Matters
The type of inlet your electric vehicle has can also influence the decision to install two separate chargers. Here's why:
Different Inlet Types: If one vehicle in your household has a Type 1 inlet and the other a Type 2, they might not be able to share a charger, necessitating two separate chargers.
Universal Chargers: Some chargers are designed to be compatible with both Type 1 and Type 2 inlets, offering flexibility if your household has different types of EVs.
Adapters: Using adapters to fit different inlets can be an option, but it might not be as convenient as having two separate chargers.
Understanding the compatibility of chargers with your vehicles' inlets is essential to ensure efficient and convenient charging.
Alternative Charging Options
If you decide to opt for a single home charger, there are other ways to charge your electric vehicle, such as:
Public Charging Infrastructure: Utilising public charging stations can be a practical solution, especially if there are convenient locations near your workplace or regular destinations.
Slower Three-Pin Plug Charging: While not ideal for daily charging, a three-pin plug can be used as a backup or occasional charging solution as long as total load on the outlet is limited to less than 2kW.
Exploring alternative charging options can provide flexibility and reduce the need for multiple home chargers.
Conclusion: Weighing the Pros and Cons of Dual Home Charging
Deciding whether to install one or two electric vehicle chargers for your home requires carefully weighing several factors. While dual charging is possible, it may not be the best solution for every situation.
Having two chargers can provide convenience and maximize charging speed, especially for households with multiple EVs, busy driving schedules, and available space. However, the costs are doubled, and charging speed can still be impacted by electricity supply and load-balancing capabilities.
In some cases, a single charger coupled with public charging or occasional three-pin plug charging may suffice. This comes down to thoroughly assessing usage needs and patterns.
The growth of EVs will continue to make dual home charging considerations more common. By understanding the costs, evaluating your needs, and exploring alternatives, EV owners can make the optimal charging decision for their households.
While two chargers may seem ideal, take the time to weigh the pros and cons outlined in this guide before moving ahead with a dual home charging investment.
As the United Kingdom gears up for a greener future, electric vehicles (EVs) are rapidly becoming the new norm on British roads. Driven by government policy, environmental awareness, and advancements in EV technology, the shift towards electric mobility is accelerating. But a question that often arises is, "Where will the electricity for electric vehicles come from?" Let's explore the UK's plans for powering EVs, focusing on renewable energy sources and the capacity of the UK's electricity grid.
The UK's Renewable Energy Revolution
Wind Power: The UK's Green Energy Champion
The United Kingdom is a global leader in wind power, boasting both onshore and offshore wind farms. With the largest offshore wind capacity in the world, projects like the UK's Hornsea One, completed in October 2019, are setting records. The government and industry are targeting at least 30,000MW of offshore wind capacity by 2030, positioning wind power as a crucial source of EV electricity.
Solar and Other Renewable Sources
Solar power, hydropower, and bioenergy also contribute to the UK's renewable energy mix. With over a million solar installations across the country, these renewable sources are providing an increasingly sustainable electricity supply for electric vehicles.
In the third quarter of 2019, the UK's renewable energy sources generated more electricity than coal, oil, and gas combined for the first time since 1882. Since that historic moment, the UK has continued to invest in and expand its renewable energy capacity. By the end of 2021, renewable energy accounted for over 40% of the UK's total electricity generation. This growth is driven by government incentives, technological advancements, and a commitment to achieving net-zero carbon emissions by 2050. This shift towards renewable energy is vital for EVs, as it ensures that the electricity used to charge them is becoming cleaner.
The Role of the National Grid in EV Charging
Managing Supply and Demand
The National Grid is at the heart of the UK's electricity system, responsible for balancing supply and demand across the country. As the number of electric vehicles on British roads continues to grow, the demand for electricity to charge these vehicles is also increasing. This presents both challenges and opportunities for the National Grid.
Smart Charging Solutions
Smart charging solutions are becoming essential in managing this growing demand. These systems can charge EVs during off-peak times when the need for electricity is low, such as late at night or early in the morning. By shifting EV charging to off-peak hours, the National Grid can balance the load on the grid, ensuring a stable electricity supply and making efficient use of existing infrastructure.
An emerging innovation in the field of EV charging is Vehicle-to-Grid (V2G) technology. V2G allows electric vehicles to not only draw power from the grid but also feed electricity back into it. This bi-directional flow of energy can help stabilize the grid during peak demand periods. Electric vehicles can act as mobile energy storage units, providing a flexible and responsive energy resource for the National Grid.
Infrastructure Upgrades and Investments
To support the growing number of electric vehicles, the National Grid is investing in infrastructure upgrades and expansions. This includes adding new transmission lines, substations, and other essential components to handle the increased load. These investments are crucial for maintaining the reliability and resilience of the electricity system as EV adoption accelerates.
Collaboration with Local Distribution Network Operators and Utilities
The National Grid is also collaborating with local distribution network operators and utility companies to develop localised charging solutions. This includes creating community charging hubs, supporting workplace charging, and developing urban charging networks. These localised solutions help distribute the load evenly across the grid and provide convenient charging options for EV owners.
Home Charging and Solar Power: A Sustainable Solution
Many UK EV owners charge their vehicles at home, benefiting from off-peak electricity rates and the convenience of home charging. For those with solar panels, the benefits are even greater. By using electricity generated by their own solar systems, homeowners can reduce their reliance on the grid and power their vehicles with 100% renewable energy.
With the advent of smart home energy systems and battery storage solutions, homeowners can store excess solar power for use at night, further enhancing the efficiency of home charging.
