The Chinese Vehicle Collision Repair Technical and Research Center and Joyson Electronics have revealed a very unusual solution to a serious concern. However, there are naturally concerns over the high-speed ejection of a battery weighing potentially several hundred kilograms. EV fires can be caused by battery cells overheating after their cathodes and anodes make contact and short circuit, generating heat which spreads to surrounding cells, creating a chain reaction almost impossible to reverse – with temperatures rising to about 1000°C. According to Australian organisation EV FireSafe, though, EV battery fires are rare. Its research found there were a total of 393 verified EV traction battery fires globally between 2010 and June 30, 2023, though it notes this data isn’t exhaustive.
