The present invention relates to a power control device, comprising a vehicle-mounted charger, a power distribution device, and a power conversion device, which are accommodated in a single case. The vehicle-mounted charger receives status information of a battery pack from a battery management system through a CAN driver, and varies and outputs a value of a DC output voltage in accordance with the status information of the battery pack. The power distribution device distributes power by converting relay contacts in accordance with the control of the vehicle-mounted charger. The power conversion device receives the DC output voltage of the vehicle-mounted charger as an input, converts and outputs the input into a charging voltage of a low-voltage battery, and can receive variable information of the DC output voltage and convert the DC output voltage into a constant charging voltage of the low-voltage battery.

    본 발명은 전력 제어 장치에 관한 것으로, 하나의 케이스에 수용되는 차량 탑재형 충전기, 전력분배장치 및 전력변환장치를 포함하되, 상기 차량 탑재형 충전기는 캔 드라이버를 통해 배터리 관리 시스템으로부터 배터리팩의 상태 정보를 수신하고, 배터리팩의 상태 정보에 따라 직류 출력전압의 값을 가변하여 출력하며, 상기 전력분배장치는 상기 차량 탑재형 충전기의 제어에 따라, 릴레이 접점을 변환하여 전력을 분배하고, 상기 전력변환장치는 상기 차량 탑재형 충전기의 직류 출력전압을 입력으로 하여, 저전압 배터리의 충전 전압으로 변환하여 출력하되, 직류 출력전압의 가변 정보를 수신하여, 일정한 저전압 배터리의 충전 전압으로 변환할 수 있다.
