Abstract
A vehicle includes a battery charger system arranged to charge a traction battery. The battery charger system receives current from a power distribution system remote from the vehicle and outputs the current to the traction battery at a series of magnitudes to characterize a charge efficiency profile of the battery charger and power distribution systems. The battery charger system then charges the traction battery according to the charge efficiency profile.
