Abstract

See full text

A vehicle includes a controller that, responsive to data indicating a voltage associated with an inrush current through a main contactor exceeds a first threshold, commands the main contactor to open and inhibits the vehicle from being driven, and responsive to data indicating the voltage exceeds a second threshold less than the first threshold, commands the main contactor to sequentially open and then close.
