The present invention is an electronically controlled battery contactor that opens (disconnects) or closes (connects) the battery circuit from the other parts of a motor vehicle electrical system based on measured or sensed data derived from monitoring the electrical system, communicating with other on-board control units, and pre-programmed requirements specific to the vehicle operation. The primary functions are to protect the battery from excessive current drain when the vehicle is parked, protect against short circuits across the main electrical feed, and provide emergency disconnect for vehicle impact, rollover or sensed thermal events. A programmed delay function controls the opening of the contactor in conjunction with other electronic control units that may require electrical power for a period of time after vehicle shutdown. A master electrical disconnect switch is provided for manual override for servicing the vehicle or during an emergency.
