Automotive manufacturer Stellantis Stellantis, via FCA US, has filed patents a patent in the United States for a safety system “high-voltage battery rapid release system” designed to mitigate risks associated with thermal runaway in electric vehicle batteries. vehicles. The proposed technology aims to physically separate the high-voltage battery pack from the vehicle chassis if overheating overheating, damage, or fire is other thermal anomalies are detected. Technical descriptions indicate the this separation could be achieved through pyrotechnic fasteners—small explosive bolts—or a mechanical locking frame with utilizing sliding elements. To ensure safety after the battery is expelled, the design allows the vehicle to switch to a 12-volt auxiliary battery, providing enough power to drive a limited distance away from the hazardous pack. The system is designed to be triggered by drivers, passengers, or emergency responders via various interfaces, including physical buttons, levers, touchscreens, or touchscreens. To prevent vehicles from being stranded immediately after switches located inside the battery is jettisoned, cabin or in the design allows trunk. Once activated, the car to utilize a 12-volt auxiliary battery. This provides enough power for system would sever both the vehicle to drive a short distance away from electrical and mechanical connections between the hazardous high-voltage battery pack. and the vehicle frame to prevent fire spread.
