Abstract: A mobile application includes a motive power circuit having a power storage device and an electrical load, where the power storage device and the electrical load are selectively electrically coupled through a power bus. The application includes a power distribution unit (PDU) electrically interposed between the power storage device and the electrical load, where the PDU includes a breaker/relay positioned on one of a high side and a low side of the power storage device. The breaker/relay includes a fixed contact and a moveable contact selectively electrically coupled to the fixed contact, where the moveable contact allows power flow through the power bus when electrically coupled to the fixed contact, and prevents power flow through the power bus when not electrically coupled to the fixed contact. The breaker/relay includes an armature coupled to the moveable contact, and capable to open or close the motive power circuit.

Abstract: Electrical current sensing and monitoring methods include connecting a compensation circuit across a conductor having a non-linear resistance such as a fuse element. The compensation circuit injects a current or voltage to the conductor that allows the resistance of the conductor to be determined. The current flowing in the conductor can be calculated based on a sensed voltage across the conductor once the resistance of the conductor has been determined.
