More Information
Summary:A power supply system and method for charging a battery of a vehicle are provided and include a charger that is configured to charge the battery and a charging controller that is configured to receive a voltage to charge the battery and operate the charger. An auxiliary battery is configured to supply a first DC voltage to operate the charging controller and a power supplier is configured to generate a second DC voltage greater than the first DC voltage using external AC power, and to supply the second DC voltage to the charging controller as a driving power source to charge the battery. First and second diodes are respectively installed at output ends of the power supplier and the auxiliary battery, a cathode voltage of the second diode is increased when the power supplier supplies the second DC voltage, and the first DC voltage of the auxiliary battery is blocked.
