Abstract
Systems and methods for de-energizing battery packs in vehicles that receive at least a portion of their motive power from electricity generated from a battery are provided. By way of example, one embodiment includes a battery de-energizer that is configured to electrically couple to a port or receptacle, such as the service disconnect receptacle, on the vehicle and discharge the electrical energy stored in the battery pack. Another embodiment includes a battery management unit (BMU) designed to monitor one or more sensors to determine if a crash has occurred. If a crash is determined, the BMU electrically couples a battery de-energizer circuit to the battery pack to discharge the electrical energy stored in the battery pack.
