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.
Claims15
A vehicle comprising:
- a traction battery;
- and
- a battery charger system configured to receive current from a power distribution system remote from the vehicle, to output 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, and to charge the traction battery based on the charge efficiency profile.
A battery charger system comprising:
- a controller arrangement configured to receive energy from a power distribution circuit defined by wiring connecting a power source remote from a vehicle and the controller arrangement and to output a charge current at a magnitude that depends on a resistance of the wiring.
A method of operating a battery charger system of a vehicle comprising:
- receiving current from a power distribution system remote from the vehicle;
- outputting the current to a traction battery at a series of magnitudes to characterize a charge efficiency profile of the battery charger and power distribution systems;
- and
- charging the traction battery based on the charge efficiency profile.
