These experimental EV batteries can eject themselves during a fire

Chinese researchers reportedly tested an ejectable EV battery pack designed to throw the pack clear of a vehicle when a fire begins, in about one second. Videos shared online show a system that detects battery fire conditions and uses a gas generator, similar to an airbag inflator, to push the pack sideways. The prototype is described as coming to rest roughly 10 to 20 feet from the car. The concept remains early-stage, and there are unresolved questions about whether a displaced pack could land near people or other vehicles. The article also notes that Joyson Electronics denied any joint development with the body credited, and iCar/Chery said it had nothing to do with the demo.
