Abstract
A vehicle includes a contactor electrically between a charge port and a traction battery, and a controller configured to maintain the contactor in a closed position until a charge current estimate, derived from vehicle load data without sensing current through the contactor or receiving data from a charge station regarding the current, is less than a predetermined threshold. The maintenance of the contactor position is responsive to a charge disconnect request.
