EV Drivers Face Rising Risks of Fire and Explosions, Warns Report

Electric vehicle (EV) drivers are being cautioned about increasing risks associated with car fires and potential explosions, according to a recent report published by Allianz Commercial. The study highlights significant safety concerns that could arise as the number of electric vehicles on the road is projected to exceed 200 million by the end of the decade.

The “Global Risk Dialogue” report outlines that while electric vehicles are not statistically more likely to catch fire compared to traditional internal combustion engine vehicles, they carry unique hazards. These include the potential for “thermal runaway,” which can lead to explosions and the release of hazardous materials, such as heavy metals and toxic chemicals.

Charging Risks and Safety Measures

Rafael Rioboo, Regional Head of Risk Consulting for Allianz Commercial’s Iberia region, emphasizes that the most dangerous moment for an EV concerning battery risks is during the charging process. He notes that electric vehicle chargers may overheat or short-circuit, potentially damaging the vehicle’s battery system.

The report also indicates that law enforcement agencies are responding to these risks by isolating vehicles involved in accidents to manage “post-crash battery hazards.” Rioboo warns, “Thermal runaway doesn’t wait for you to act – it ignites, escalates, and overwhelms.” He adds that this phenomenon can result in fires, explosions, and the release of harmful gases, including carbon monoxide and hydrogen cyanide, which pose serious threats to people, property, and emergency responders.

Expert Opinions on Fire Risks

Despite the alarming warnings, not all experts agree that electric vehicles are inherently more dangerous than their gasoline counterparts. Colin Walker, head of transport at the Energy and Climate Intelligence Unit, asserts, “All the data shows that EVs are just much, much less likely to set on fire than their petrol equivalent.” He points out that the numerous fires associated with petrol or diesel vehicles often go unreported, creating a skewed perception of risk.

Paul Christensen, a professor of pure and applied electrochemistry at Newcastle University, studies battery technology and provides training for fire brigades. He highlights significant risks associated with EV batteries, including the potential for “vapour cloud explosions and rocket flames” when gases escape from cells.

The insights provided by Allianz Commercial and various experts underscore the need for ongoing education and safety measures for EV drivers. As the adoption of electric vehicles accelerates, understanding the associated risks and improving charging infrastructure will be crucial for ensuring driver safety and public confidence in this evolving technology.
