The present invention discloses a battery charging apparatus for an electric vehicle. The battery charging apparatus may include a generator which can be selectively combined with a battery module, generates charging power by driving a motor, controls the toque of the motor by a control current acting on the rotor of the motor, outputs the charging power, and outputs a feedback signal of the charging power, and a control circuit which firstly controls an amount of control currents by using the feedback signal, and secondarily controls the control current by controlling the feedback signal by corresponding to a comparison result of the feedback signal with charging information. So, the battery module can be selectively combined with the electric vehicle.

    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.
