Zusammenfassung:	Systems and methods for disconnection of battery power from vehicular components in an electric vehicle upon the occurrence of a crash event are described. In an embodiment of an electric vehicle, upon detection of a crash event, an appropriate signal is transmitted through a controller area network (CAN). A battery management unit (BMU) detects the signal and then severs a power connection between the battery and one or more vehicular components of the electric vehicle. In another embodiment of an electric vehicle, a crash event is detected and a signal to deploy an airbag and/or a pretensioner is emitted. Once a decision is made to deploy the airbag and/or the to pretensioner, the BMU then cuts off battery power to one or more vehicular components of the electric vehicle.
