CONTROL AND DIAGNOSIS OF CHARGING SYSTEM FOR A VEHICLE

A controller, during charging of a traction battery by a remote charger, and responsive to a difference between a requested charge current and a current supplied by the remote charger exceeding a first threshold value for a predefined period of time, increases a requested charge voltage to a limit value. The controller further, responsive to a voltage across a capacitor and a voltage across the traction battery being same, and a voltage of the remote charger and the limit value being same, commands the remote charger to discontinue the charging.
