As electric vehicles (EVs) continue to surge in popularity across the UK, safety concerns—particularly around EV fires—have become a growing public conversation. With over 975,000 battery-electric cars now on UK roads as of early 2025, up from just 108,000 in 2019, the electric revolution is well underway. But along with this rise comes increased scrutiny, especially when it comes to battery-related incidents.
Despite media headlines highlighting dramatic EV fires, data from the UK’s Department for Transport and insurers such as AXA UK show that EVs are statistically less likely to catch fire than petrol or diesel vehicles. In fact, the rate of vehicle fires for EVs is estimated to be about 25 per 100,000, compared to 1,530 per 100,000 for internal combustion engine (ICE) vehicles. Still, the fear persists—often fuelled by misinformation or lack of awareness about how EV batteries function and what safety mechanisms are in place.
This guide aims to unpack the real risks, bust common myths, and offer practical guidance on how to prevent EV fires—whether you’re charging at home, on the road, or managing a fleet. We’ll also spotlight how Smart EV Charging Solutions in the UK are stepping up safety with intelligent design and proactive features.
Brands like CITA EV Charger, a leading EV charger manufacturer in the UK, are paving the way with robust technologies that prioritise safety without compromising on performance. Let’s take a deeper dive into the truth about EV fires—and what you can do to stay protected.
Are EV Fires a Real Threat?
Let’s start with the facts.
All vehicles—gasoline, diesel, or electric—carry some risk of fire. In fact, research consistently shows that internal combustion engine (ICE) vehicles are more likely to catch fire than EVs. According to data from the National Transportation Safety Board, EVs catch fire at a significantly lower rate than petrol or diesel cars.
That said, when an EV fire does occur, it can be more challenging to extinguish. This is due to the lithium-ion battery chemistry, which, under extreme conditions (such as physical damage, manufacturing defects, or improper charging), can lead to thermal runaway—a chain reaction that can result in fire or explosion.
But here’s the truth: EV fires are extremely rare. When they do occur, improper charging methods, outdated infrastructure, or untested equipment are often to blame—not the vehicle itself.
Top Causes of EV Fires
Understanding the root causes of EV fires is essential to reducing risk and promoting safer electric mobility. While EVs are generally safe, specific factors can contribute to battery-related incidents. Let’s explore the primary causes:
1) Battery Damage or Manufacturing Defects
Electric vehicles rely on complex lithium-ion battery systems, which must be manufactured with extreme precision. Even a minor defect during production—such as poorly aligned cells, contamination, or faulty separators—can increase the chances of a short circuit.
Over time, such flaws may worsen under high temperatures or mechanical stress, leading to internal cell overheating and potential fires. Leading EV manufacturers like CITA EV Charger have introduced rigorous quality control measures, but occasional defects still pose risks, especially in lower-cost or non-certified battery packs.
2) Overcharging or Improper Charging
Overcharging an EV battery can lead to excessive heat buildup and battery degradation. This is often caused by using incompatible, uncertified, or outdated chargers that lack proper communication with the vehicle’s onboard battery management system. Poorly installed home chargers or makeshift solutions also pose serious hazards.
Reputable EV charger service providers in the UK stress the importance of using certified chargers that meet UK safety regulations and come equipped with intelligent charging features like auto shut-off, thermal regulation, and voltage monitoring.
3) Physical Damage from Accidents
EV batteries are usually mounted beneath the vehicle floor, making them vulnerable in the event of a high-impact collision or road debris strike. Damage to the battery enclosure can puncture or crush individual cells, triggering short circuits and thermal reactions.
Although EV charger manufacturers are now using reinforced casings and protective structures to shield battery packs, post-accident battery assessments remain crucial for early detection of internal damage that may lead to delayed fires.
4) Thermal Runaway
Thermal runaway refers to a dangerous chain reaction where an overheated battery cell causes surrounding cells to heat up and fail. This process can escalate quickly, resulting in fires or explosions. While rare, thermal runaway is extremely difficult to stop once initiated.
The risk is heightened by poor thermal management, inadequate cell spacing, and uncontrolled charging. High-quality EVs and certified EV chargers use sophisticated battery management systems to constantly monitor temperature and prevent runaway events before they start.
5) Exposure to Extreme Temperatures
Extreme heat or cold can significantly affect battery chemistry and stability. High ambient temperatures, especially during summer heatwaves or in poorly ventilated garages, can increase the chances of battery swelling, electrolyte leakage, or overheating. On the flip side, charging an EV in freezing temperatures without pre-conditioning can stress battery cells.
Today’s smart EV charging solutions in the UK often include built-in thermal sensors and ambient temperature controls, ensuring the battery only charges within safe limits to preserve long-term health and reduce fire risks.
How to Prevent EV Fires: Smart Charging & Safety Tips
