EV Drivers Warned of Fire and Explosion Risks Amid Rising Popularity

A new report from Allianz Commercial highlights significant risks associated with electric vehicle (EV) ownership, prompting a warning to drivers. As the number of electric vehicles on roads is projected to exceed 200 million by the end of the decade, concerns are growing over potential fire hazards, including the risk of explosions and the release of toxic chemicals.

The report, titled “Global Risk Dialogue,” emphasizes that while electric vehicles are not inherently more prone to catching fire compared to traditional internal combustion engine vehicles, serious risks do exist. According to the findings, incidents related to EV charging can lead to dangerous situations such as “thermal runaway,” which may ignite fires and cause the release of harmful substances.

Rafael Rioboo, Regional Head of Risk Consulting for Allianz Commercial in the Iberia region, stated, “The riskiest moment in an EV’s life concerning battery risk isn’t driving – it’s charging.” He cautioned that overheating or short-circuiting of electric vehicle chargers could severely damage the vehicle’s battery system.

Concerns Over Battery Hazards

The report also indicates that law enforcement agencies are taking proactive measures to manage risks associated with electric vehicles. This includes isolating vehicles after accidents to address “post-crash battery hazards.” Rioboo noted that “thermal runaway doesn’t wait for you to act – it ignites, escalates and overwhelms.” This phenomenon can lead to fires, explosions, and the release of hazardous materials, including heavy metals and toxic gases such as carbon monoxide and hydrogen cyanide.

Despite these concerns, some experts assert that electric vehicles are statistically safer in terms of fire risk. Colin Walker, head of transport at the Energy and Climate Intelligence Unit, remarked, “All the data shows that EVs are just much, much less likely to set on fire than their petrol equivalent.” He pointed out that many incidents involving petrol or diesel vehicles often go unreported, skewing public perception of fire risks.

Research and Training Initiatives

Further insights into the risks posed by electric vehicle batteries come from Paul Christensen, a professor of pure and applied electrochemistry at Newcastle University. Christensen, who studies batteries and trains fire brigades, warns of the potential for “vapour cloud explosions and rocket flames” when gases escape from battery cells.

As the electric vehicle market continues to expand, awareness and education surrounding battery safety and fire hazards will be crucial. The Allianz report encourages both manufacturers and consumers to prioritize safety measures to mitigate these risks and ensure the safe operation of electric vehicles on the roads.
