International Classification:

H02J 7/00
B60R 16/033

Abstract:

A method includes interpreting a contactor open event and a contactor load value for a contactor positioned on a motive power circuit for a mobile application, determining that a contactor opening event under load has occurred in response to the contactor open event and the contactor load value, and updating a contactor wear condition in response to the contactor opening event under load, wherein updating the contactor wear condition comprises accumulating a number of the contactor opening events under load.

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.
