Abstract:
1. A battery disconnect apparatus for monitoring and controlling the battery to electrical load circuit completion or interruption based upon vehicle electrical system states comprising: a battery for supplying electrical power to the vehicle circuits; an alternator to maintain electrical power while the engine is operating and to recharge the battery; a key switch for initiating the starting of the vehicle engine and completing the electrical circuits to switched electrical vehicle loads; a battery contactor interposed in the vehicle electrical system between the battery and the vehicle electrical devices and loads, including switched and unswitched electrical loads; and a controller module for sensing the state of the battery contactor and sensing the state of the key switch by initiating a voltage pulse through the voltage output of the battery contactor and sensing and comparing the voltage input from the key switch and issuing electrical control signals to the battery contactor to close upon sensing key closure.
