Abstract: A system include a vehicle having a motive electrical power path and a power distribution unit (PDU). The PDU includes a current protection circuit disposed in the motive electrical power path, the current protection circuit including a thermal fuse and a contactor in a series arrangement with the thermal fuse, and a high voltage power input coupling having a first electrical interface for a high voltage power source. The high voltage power output coupling includes a second electrical interface for a motive power load. The current protection circuit electrically couples the high voltage power input to the high voltage power output, and the current protection circuit is at least partially disposed in a laminated layer of the PDU. The laminated layer includes an electrically conductive flow path disposed between two electrically insulating layers.

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: A compact fusible disconnect switch device includes a magnetic arc deflection assembly including pairs of magnets disposed about a mechanical switch contact assembly. The magnetic arc deflection assembly facilitates reliable connection and disconnection of DC circuitry operating at a voltage well above 125 VDC with reduced arcing intensity and duration. The pairs of magnets may apply magnetic fields in directions opposing one another to deflect electrical arcs in different directions at different locations in the mechanical switch contact assembly to facilitate high voltage DC switching operation.

Abstract: Electrical current sensing and monitoring methods include connecting sensing a voltage across a conductor having a non-linear resistance such as a fuse element. The current flowing in the conductor is calculated based on at least a first detected state of the sensed voltage and a thermal equilibrium characterization of the conductor.
