Abstract: Arc fault detection modules for vehicles intended to supervise circuits and detect arc fault conditions in both alternating current and direct current circuits. A number of these arc fault detection modules may be integrated into a vehicle's electrical system in strategic locations. Each arc fault module contains sensing capabilities for monitoring the circuit, and may also include signal conditioning capabilities, processing capabilities for determining the occurrence of an arc fault, contactors for disabling the supervised circuit, and communications capabilities to interact with other vehicle components and telematics systems. As a result arc fault detection odules can be customized to leverage existing features of a vehicle's electrical system or to provide fully redundant arc fault protection.

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.
