Abstract
Official abstract text for this publication.
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.
