The idea is unusual: instead of trying to cool a damaged battery, the car will be able to disconnect it from the body. The system simultaneously breaks electrical connections and mechanically releases the battery pack. The patent considers various mechanism options, including sliding frame elements and pyrotechnic fasteners.

After disconnecting the traction battery, the car should not remain stationary. The controller connects a low-voltage battery, such as a standard 12-volt one, to the electric motor and makes the car travel a predetermined distance from the battery pack left on the road. The exact distance is not specified in the patent.

It is assumed that the system can be activated by the driver, passenger, or rescuer. The switch can be located in the cabin or luggage compartment, and its design allows for a button, lever, switch, or touch control element. Automatic activation by a sensor is not provided in the system description.

The main practical purpose of the development is to increase the distance between the car and a potentially dangerous battery in case of damage or overheating. However, for now, this is a patent development, not an announcement of serial technology: Stellantis has not announced plans to install the mechanism on a specific model.
