Claim:
1. A battery charging system using a charger, comprising: an on board charger (OBC) configured to include a power factor corrector (PFC) converter connectable to an output terminal of an alternating current (AC) power unit, and a direct current-direct current (DC-DC) converter connected between the PFC converter and a high voltage battery; and a controller configured to determine the presence of generation of charger input voltage VIN output from the AC power unit and determine output current Ioref or output power Poref of the DC-DC converter, based on the determination of the presence of generation of charger input voltage VIN output, wherein when the charger input voltage VIN is not generated, the controller is configured to determine the output current of the DC-DC converter as a current less than the output current in the generation of the charger input voltage VIN.
