1. A system in an automobile adapted to disconnect electrical power in the automobile upon detection of a crash event, the system comprising:

  • at least one vehicular component;

    a battery for supplying electrical power to the at least one vehicular component;

    a contactor for providing electrical communication between the at least one vehicular component and the battery when the contactor is in a closed configuration;

    a battery management unit in communication with the contactor and being adapted to provide a disconnect signal that results in the contactor achieving an open configuration that severs a power connection between the at least one vehicular component and the battery;

    a crash detection unit adapted to emit a crash signal upon making a determination as to whether the crash event has occurred; and

    a controller area network in communication with a plurality of control units including the battery management unit and the crash detection unit, wherein upon occurrence of the crash event, the controller area network is adapted to receive the crash signal from the crash detection unit and the battery management unit is adapted to sense a signal that indicates that the crash event has occurred from the controller area network for emitting the disconnect signal.
