The present invention relates to a high-speed charger for an electric vehicle having a parallel controller which does not stop charging even if a current charged to an electric vehicle from a high-speed charger is changed. The high-speed charger for an electric vehicle having a parallel controller comprises: a battery pack unit having a first battery pack and a second battery pack connected in parallel; a battery pack parallel control unit connected to the battery pack unit to measure the voltage and current of the battery packs and control current amounts discharged from the first battery pack and the second battery pack when a voltage difference of the first battery pack and the second battery pack occurs; a DC-DC converter unit maintaining the current discharged from the battery packs at a set voltage to maintain the current charged to an electric vehicle at a set voltage; a PC control unit communicating with the electric vehicle to transceive information on the voltage and current required in the electric vehicle and control the battery parallel control unit; and a socket unit connecting the DC-DC converter unit and the electric vehicle.

    본 발명은 제1 배터리팩과 제2 배터리팩이 병렬 연결되는 배터리팩부와, 상기 배터리팩부와 연결되어 상기 각각의 배터리팩의 전압과 전류를 측정하고, 상기 제1 배터리팩과 제2 배터리팩의 전압차가 발생시 상기 제1 배터리팩과 상기 제2 배터리팩에서 방전되는 전류량을 제어하는 배터리팩 병렬 제어부와, 전기차로 충전되는 전류가 설정된 전압을 유지하도록, 상기 배터리팩에서 방전되는 전류를 설정된 전압으로 일정하게 유지하는 DC-DC 컨버터부와, 전기차와 통신하여 전기차에서 필요한 전압 및 전류에 대한 정보를 송수신하고, 상기 배터리 병렬 제어부를 제어하는 PC 제어부 및, 상기 DC-DC 컨버터부와 전기차를 연결하는 소켓부를 포함하는 병렬 제어기를 구비하는 전기차 급속 충전기에 관한 것이다.
