The fire service is undertaking a comprehensive review of incidents involving electric vehicle (EV) battery fires, as concerns over the risks associated with lithium-ion batteries continue to grow. This initiative reflects a commitment to promoting greater responsibility in handling and disposing of these batteries to prevent dangerous fires.
Recent months have seen a noticeable increase in fires linked to EVs and other lithium-ion battery-powered devices. One high-profile incident occurred last October on the M5 motorway in Devon, where a car transporter carrying nine electric vehicles caught fire following a series of explosions, resulting in prolonged motorway closures.
During a meeting of the Devon & Somerset Fire and Rescue Authority, Councillor Jeff Trail inquired whether the fire service maintained detailed records distinguishing between fires involving traditional combustion engine vehicles and those involving EVs. He was informed that the Authority had indeed discussed EV battery fires at recent community safety meetings and planned a “deep dive” analysis led by its Community Safety Committee.
Chief Fire Officer Gavin Ellis highlighted a “growing trend” in lithium-ion battery-related incidents. In response, the fire service is intensifying its outreach efforts, spearheading safety campaigns delivered through community teams and frontline fire crews to raise public awareness.
Deputy Chief Gerald Taylor emphasized the importance of a national campaign, especially active during the Christmas season, which urges households to dispose of lithium-ion batteries responsibly. He noted, “The campaign encourages people to recycle devices with lithium-ion batteries properly because improper disposal—such as placing them in regular waste or scrap collections—has led to serious fires.”
Taylor also pointed to the severe impact of the M5 incident, where a lorry fire caused by lithium-ion batteries forced the motorway to close for several hours. In addition to the car transporter, another battery-carrying lorry caught fire on the same motorway later that month. Across the country, bin trucks have also experienced fires believed to be sparked by improperly discarded lithium-ion batteries.
The Fire Protection Association explains that these batteries can suffer a phenomenon known as “thermal runaway.” This occurs when a battery cell produces more heat than it can dissipate, leading to a rapid and uncontrollable release of heat energy that may result in fire or explosion.
This heightened focus on EV and lithium-ion battery fires underscores the need for increased public education and safer practices in handling these increasingly common energy sources.
