In a water-cooled electric vehicle power control device capable of further increasing cooling efficiency, an electric vehicle power control device comprises an electric vehicle-specific component including an on-board charger (OBC), a power distribution unit (PDU), and a low voltage DC-DC converter (LDC) and a cooling system that allows a refrigerant to flow through an internal hollow part. The cooling system is in contact with at least one of the OBC, the PDU, and the LDC and receives heat from the electric vehicle-specific component.
본 발명은, 냉각 효율이 보다 증대될 수 있는 수랭식 전기차 전력 제어 장치에 있어서, OBC(On-board Charger, 차량 탑재형 충전기), PDU(Power Distribution Unit, 전력 분배 장치) 및 LDC(Low voltage DC-DC Convertor, 저전압 DC 컨버터)가 구비되는 전기차 전용 부품 및 내부의 중공부로 냉매가 유동될 수 있는 냉각 시스템을 포함하고, 상기 냉각 시스템은, 상기 OBC, 상기 PDU 및 상기 LDC 중 적어도 어느 하나에 접하며, 상기 전기차 전용 부품으로부터 열을 전달받는, 전기차 전력 제어 장치를 개시한다.
