The present invention discloses a battery charging apparatus for an electric vehicle. The battery charging device may include a generator which is configured to be selectively coupled to a battery module, generates electric power for charging by driving a motor, controls the torque of the motor by a control current acting on the rotor of the motor, outputs charging power, and outputs the feedback signal of the charging power, and a control circuit which primarily controls the amount of a control current by using the feedback signal and secondarily controls the amount of the control current by controlling the feedback signal in accordance with the result of comparing the feedback signal with charge information. So, the battery charging apparatus can be modularized with the battery module.

    본 발명은 전기 자동차의 배터리 충전 장치를 개시하며, 배터리 충전 장치는 배터리 모듈과 선택적으로 결합 가능하도록 구성될 수 있으며, 모터를 구동하여 충전용 전력을 생성하며, 모터의 회전자에 작용하는 제어 전류에 의하여 모터의 토크가 제어되고, 충전용 전력을 출력하며, 충전용 전력의 피드백 신호를 출력하는 발전기 및 피드백 신호를 이용하여 제어 전류의 양을 1차 제어하며, 피드백 신호와 충전 정보를 비교한 결과에 대응하여 피드백 신호를 조절함에 의하여 제어 전류의 양을 2차 제어하는 제어 회로를 포함할 수 있다.
