From Watts Up With That?<\/a><\/p>\n\n\n\n

The new, unusual solution to EV fires: High-speed battery ejection<\/strong><\/p>\n\n\n\n

New technology has been demonstrated in China that sees an electric vehicle\u2019s battery rapidly ejected to keep occupants safe from an imminent fire.<\/p>\n<\/blockquote>\n\n\n\n

At an event earlier this month, new technology was demonstrated on Chery\u2019s iCar 03<\/a> that can see a vehicle\u2019s high-voltage battery ejected 3-6 metres away within a second of thermal runaway being detected.<\/p>\n\n\n\n

It\u2019s ejected from the vehicle using a gas generator, much in the same way as an airbag works, with the idea to get the battery away from vehicle occupants before it catches fire.<\/p>\n\n\n\n

In the demonstration video, shared across Chinese media including cnBeta<\/em><\/a>, the battery is ejected with a bang into a nearby pit and then quickly shrouded.<\/p>\n\n\n\n

However, there are naturally concerns over the high-speed ejection of a battery weighing potentially several hundred kilograms.<\/p>\n\n\n\n

My first thought was, surely this is a joke. But if it is a joke, someone has gone to a lot of trouble to make it look real.<\/p>\n\n\n\n

Someone should tell them that for a modern EV battery to go critical it needs quite an heavy impact\u2026which would destroy this \u201ebattery ejection system\u201c. pic.twitter.com\/toJi8jbfkx<\/a><\/p>— \ud83c\udde8\ud83c\uddf3China EV, Engineering & Life\ud83c\udde9\ud83c\uddea (@ChinaEV_Eng_Lif) September 20, 2025<\/a><\/blockquote>
