The present invention relates to a technology about a battery charging apparatus for a green car and a battery charging method thereof. The present invention comprises: an inverter for receiving single phase AC voltage through a power system and converting the single phase AC voltage into DC voltage; a converter control unit for receiving a current command from the outside, detecting error current corresponding to the difference between the current command and charge current flowing in the battery, extracting a forward compensation component corresponding to the size of a ripple component included in the charge current from the error current and generating a switching control signal based on the error current and the forward compensation component; and a converter for raising the DC voltage according to the switching control signal and outputting the raised DC voltage to the battery.

    본 발명은 친환경 자동차용 배터리 충전 장치 및 이의 충전 방법에 관한 기술이다. 본 발명은 전력 계통을 통해 단상 교류 전압을 전달받아 직류 전압으로 변환하는 인버터와, 외부로부터 전류 지령을 전달받고, 전류 지령과 배터리에 흐르는 충전 전류 간의 차이에 대응하는 오차 전류를 검출하고, 오차 전류로부터 충전 전류에 포함된 리플 성분의 크기에 대응하는 전향 보상 성분을 추출하고, 오차 전류 및 전향 보상 성분을 기반으로 스위칭 제어 신호를 생성하는 컨버터 제어부, 및 스위칭 제어 신호에 따라 직류 전압을 승압하여 배터리에 출력하는 컨버터를 포함한다.
