Abstract
A vehicle includes a traction battery, an electric machine, a relay electrically between the traction battery and electric machine, and a controller. When closed, the relay completes an electrical circuit including the traction battery and electric machine. The controller selectively commands the relay to open based on a voltage across a coil of the relay and a current through the coil.
