Abstract
Disclosed is a battery charger for an electric vehicle, which prevents capacitors in a circuit section from being deteriorated even when the circuit section is not used over a long period of time and can therefore charge reliably a main battery supplying power to an engine. The battery charger comprises a circuit section having capacitors for rectifying and boosting an AC input voltage; a converter section for converting a DC input voltage to an AC output voltage, boosting the AC voltage to a predetermined voltage level, and applying the AC voltage of a predetermined voltage level to the capacitors of the circuit section; and a switch section placed between a high voltage battery and the circuit section for disconnecting the high voltage battery from the circuit section when the high voltage battery is not charged, and connecting the high voltage battery to the circuit section when the high voltage battery is charged.
