EV Fire Risk: Facts and Myths Explained

Do EVs catch fire more often than petrol or diesel cars?

Based on current evidence, the short answer is no. The German Insurance Association (GDV) has found no indication in its claims data that electric vehicles have a higher fire risk than petrol or diesel cars. In 2024, the GDV recorded 13,600 fires involving comprehensively insured passenger cars in Germany, covering all types of powertrain. However, there is currently no comprehensive nationwide dataset that clearly breaks down vehicle fires by powertrain type.

This means whether EVs catch fire more often cannot be answered with a single percentage. When comparing EVs vs. petrol or diesel cars, the key takeaway is that both types of vehicle can catch fire, although the potential causes and the way a fire develops can differ.

What can cause an EV battery fire?

An EV battery fire can occur if individual battery cells are severely damaged or overheat. This can lead to what is known as thermal runaway: a battery cell heats up uncontrollably and may cause neighbouring cells to overheat as well. Possible triggers include internal defects or severe mechanical damage.

Following an accident, the fire risk of an EV can increase particularly if the high-voltage battery has been badly damaged. Modern electric vehicles are therefore equipped with safety systems designed to isolate the high-voltage system from other high-voltage components automatically in the event of a crash.

How high is the fire risk when charging an EV?

A fire is also possible while charging, but charging does not automatically mean a higher risk. The key factors are suitable charging equipment, professionally installed electrical systems and components that are in good condition. Potential problems can arise from unsuitable chargers or building electrical systems that are not designed for EV charging.

How safe is charging an EV in a garage?

If you charge your EV in a garage, the most important factor is a professionally installed charging solution. The wallbox, cables and connectors must be suitable for the required charging power and should be free from damage. With a professional installation, regularly charging an EV at home does not generally result in an increased fire risk.

Based on current evidence, there is also no general reason to exclude electric vehicles from underground car parks because of their fire risk, provided the applicable safety and fire protection requirements are met.

Why can an EV fire appear more dangerous?

If the high-voltage battery does catch fire, firefighting procedures differ from those used for a conventional vehicle fire. The fire service may need to cool the battery for an extended period to stop the thermal reaction and prevent it from reigniting. Extinguishing an electric vehicle can therefore require more time and water.

This is one reason why individual EV fires can appear particularly dramatic. However, it does not mean that electric vehicles generally have a higher fire risk.

Charge safely and put the risks into perspective

For EV drivers, a few basic precautions are particularly important: use charging equipment correctly, do not use damaged cables or connectors, and take any vehicle warning messages seriously. Professionally installed and regularly maintained charging infrastructure also helps keep potential charging risks to a minimum.

This is exactly where we come in at JOLT: we aim to make reliable ultra-fast charging in urban areas simple and easily accessible. This allows you to charge your EV conveniently while you are out and rely on professional charging infrastructure. At the same time, understanding the facts helps you assess the fire risk of electric vehicles realistically, rather than being unsettled by isolated dramatic incidents or persistent myths.
