Abstract
The loads of a vehicle electrical system are connected to a power distribution bus through a first or through first and second latching relays. A set of vehicle mandatory loads are connected to an output side of the first latching relay to be cut off from the power distribution bus upon opening of the first latching relay. A set of vehicle optional loads are connected to an output side of the second latching relay to be cut off from the power distribution bus upon opening of the first latching relay or the second latching relay. Opening and closing of the first and second latching relays depends of the values for the measured current and measured voltage. Among factors relating to opening and closing of the first and second latching relays are measured voltage exceeding a voltage high threshold, in which case the first latching relay opens, measured voltage falling below a low voltage threshold in which case the second latching relay opens while the first latching relay remains closed and a positive current transient exceeding a minimum threshold, which opens the first latching relay.
