Technical Analysis of Lithium-ion Batteries
At the heart of every electric vehicle lies a marvel of modern engineering: the lithium-ion battery. But what makes these batteries so special, and how do they work?
Lithium-ion batteries function through the movement of lithium ions from the negative electrode to the positive electrode during discharge, and back when charging. They are favored for their high energy density, long life span, and the fact that they don’t suffer from the ‘memory effect’ seen in other rechargeable batteries.
In the context of electric vehicles, lithium-ion batteries play a crucial role. They store and release energy to power the vehicle, making them the driving force behind the vehicle’s operation. The efficiency and performance of an electric vehicle are largely dependent on the quality and condition of its lithium-ion battery.
Elon Musk, CEO of Tesla: In response to a Twitter user’s post about Tesla’s electric vehicles supposedly being less likely to catch fire than the average car, Musk said, "Not super surprising, given that internal combustion engine cars literally have ‘combustion’ in the name"
According to data from the U.S. Department of Energy, lithium-ion batteries have significantly higher energy density compared to other rechargeable batteries. This makes them an ideal choice for electric vehicles, which require powerful batteries that can last for extended periods.
However, like any technology, lithium-ion batteries are not without their challenges. In the following sections, we will delve deeper into some of these issues, including the sensationalized fear of fires. Stay tuned as we continue our journey into the electrifying world of lithium-ion batteries and electric vehicles.
Case Studies
To fully understand the issue of fire fears in electric vehicles, it’s important to examine real-life incidents. Let’s take a look at a few case studies that have made headlines in recent years.
- Case Study 1: In one notable incident, an electric vehicle caught fire while charging at a home charging station. Firefighters were called to the scene and were able to extinguish the fire. The incident was thoroughly investigated by the National Transportation Safety Board (NTSB), which found that a fault in the battery management system had caused the fire.
- Case Study 2: In another case, an electric vehicle was involved in a high-speed collision, resulting in a fire. The NTSB report indicated that the severe nature of the crash, rather than the vehicle’s electric powertrain, was the primary cause of the fire.
- Case Study 3: There have also been instances of electric vehicles catching fire without any apparent external cause. These incidents are often the result of internal faults within the battery. However, it’s important to note that such incidents are relatively rare, and manufacturers have taken steps to address these issues in newer models.
These case studies highlight the complexity of the issue. While electric vehicle fires do occur, they are often the result of specific circumstances or faults, rather than an inherent risk of electric vehicles themselves. In the next section, we’ll take a look at the regulatory perspective on this issue.
All the data shows that EVs are just much, much less likely to set on fire than their petrol equivalent. The many, many fires that you have for petrol or diesel cars just aren’t reported

Regulatory Perspective
Regulations and safety standards play a crucial role in ensuring the safe operation of electric vehicles and their lithium-ion batteries. These regulations are set by various bodies, including the National Highway Traffic Safety Administration (NHTSA) in the U.S. and the European Automobile Manufacturers Association (ACEA) in Europe.
The NHTSA has established guidelines for electric vehicle manufacturers, which include standards for the design and performance of lithium-ion batteries. These standards aim to minimize the risk of fire and ensure the safe operation of electric vehicles. Similarly, the ACEA has set forth regulations that govern the safety standards for electric vehicles sold in the European Union.
Sweden (2022): There were only 24 EV car fires in Sweden, representing 0.004 percent of battery-powered cars there. For cars running on gasoline or diesel fuel, the fire rate was 0.08 percent, or 20 times the frequency
IEEE Spectrum
In recent years, there have been discussions about updating these regulations to keep pace with the rapid advancements in electric vehicle technology. For instance, the NHTSA has proposed changes to its guidelines that would require more rigorous testing of lithium-ion batteries. The ACEA is also considering updates to its regulations to reflect the latest developments in battery technology.
These regulatory bodies continually monitor the safety performance of electric vehicles and their batteries, and they are prepared to update their regulations as needed to ensure the highest level of safety. As we continue to explore the world of electric vehicles and lithium-ion batteries, it’s important to keep these regulatory perspectives in mind.
Public Perception vs. Reality
When it comes to lithium-ion batteries and fire risks, there’s often a gap between public perception and reality. Let’s take a closer look at some of the common misconceptions.
One widespread belief is that lithium-ion batteries in electric vehicles are more prone to catching fire than conventional gasoline-powered vehicles. However, studies and surveys, such as those conducted by the American Automobile Association (AAA), suggest that while lithium-ion batteries can catch fire, the risk is comparable to, if not less than, that associated with conventional vehicles.
What is special about EVs, is that the risk isn’t over when the fire is put out. If an EV has been involved in an accident, the car can re-ignite again hours, days, even weeks after the accident. If there is energy left in the battery and it is damaged, it is of great risk

This point is echoed by experts in the field. As one battery technology expert puts it, “While lithium-ion batteries can catch fire, the risk is no greater than with conventional vehicles.” This statement underscores the fact that while the risk exists, it’s important to keep it in perspective.
Another common misconception is that a fire in an electric vehicle powered by a lithium-ion battery is more dangerous than a fire in a conventional vehicle. In reality, fires in both types of vehicles can be equally dangerous and require immediate attention.
In the next section, we’ll explore the role of media in shaping these perceptions and how it contributes to the sensationalism surrounding fire fears in electric vehicles.
Role of Media
The media plays a significant role in shaping public perception, and this is particularly true when it comes to the topic of fire fears in electric vehicles. Media coverage can often contribute to the sensationalism of these fears, amplifying concerns and sometimes creating a narrative that doesn’t fully align with the facts.
United States (2021): According to a study pointed out by AutoInsuranceEZ, vehicles that operate using gasoline are tenfold more likely to catch fire compared to EVs. In 2021, there were around 174,000 highway vehicle fires reported in the United States
Government data show gasoline vehicles are up to 100x
Consider, for example, how a single incident of an electric vehicle fire can make headlines around the world. The dramatic visuals of a burning vehicle, combined with the novelty factor of electric vehicles, can make for a compelling news story. However, the same incident in a conventional vehicle might not receive the same level of coverage.
This disparity in coverage can create a skewed perception of the risks associated with electric vehicles. As one media critic puts it, “The media often focuses on the sensational aspects of a story, which can skew public perception.” This statement highlights the power of media narratives in shaping public understanding and attitudes.
It’s important to approach media coverage with a critical eye and to seek out balanced, fact-based information. As we continue to explore the world of electric vehicles and lithium-ion batteries, understanding the role of media in shaping perceptions is key.
General Statistics: A comprehensive study on EV fire risks revealed an average annual EV fire rate of 2.44 × 10-4 fires per registered EV. This metric provides a significant benchmark, reflecting both the probability and inherent risk of such incidents
