The present invention relates to a vehicle battery cooling system in a fast charging system. The invention comprises: a high-speed power supply which supplies power to an electric vehicle battery connected via a charging plug during fast charging; a cooler which provides a cooling fluid for cooling the electric vehicle battery during rapid charging; a cooling fluid controller which supplies the cooled cooling fluid to the cooling module of the electric vehicle battery through the charging plug during vehicle fast charging by the charging plug, cools the battery, and recovers the cooling fluid that cooled the electric vehicle battery to the cooler after charging is completed; and a charging plug which has a power connection part having a plurality of power terminals connected to the high-speed power supply for power supply, and a cooling connection part having a plurality of cooling fluid pipes which deliver the cooling fluid supplied from the cooler to the cooling module of the electric vehicle battery. Therefore, the present invention can solve the problem of battery heating of an electric vehicle, which occurs during fast charging.

    본 발명은 급속 충전 시스템에서 차량의 배터리 냉각 시스템에 관한 것이다. 본 발명은 급속 충전 시, 충전 플러그를 통해 연결된 전기차 배터리에 전원을 공급하는 고속 전원 공급기; 급속 충전 시, 전기차 배터리를 냉각시키기 위한 냉각 유체를 제공하는 냉각기; 상기 충전 플러그에 의한 차량 급속 충전 시, 상기 냉각된 냉각 유체를 상기 충전 플러그를 통해 전기차 배터리의 냉각 모듈에 공급하여 배터리를 냉각시킨 후 충전 종료 시 전기차 배터리를 냉각시킨 상기 냉각 유체를 상기 냉각기에 회수하는 냉각 유체 제어기; 및 상기 고속 전원 공급기와 접속되어 전원을 공급하는 복수의 전원 단자를 구비한 전원연결부와, 상기 냉각기로부터 공급되는 냉각 유체를 전기차 배터리 냉각 모듈에 전달하는 복수의 냉각 유체관을 구비한 냉각연결부로 이루어진 충전 플러그를 포함한다.
