The present invention relates to a power relay assembly driving method for an electric vehicle and an apparatus thereof. The apparatus comprises: a precharge switching unit; a first switching unit and a second switching unit connected in series with each other, wherein the first switching unit and the second switching unit are in parallel with a relay switch, and includes a semiconductor switching element and a diode therein. Therefore, not only when power is supplied from the battery to a load side, but also when charging is performed by supplying a charging current to the battery, power can be supplied or cut off while preventing spark and arc at the relay.

    본 발명은 전기차용 파워 릴레이 어셈플리 구동 방법 및 장치를 공개한다. 본 발명은 프리차지 스위칭부와, 서로 직렬로 연결된 제 1 스위칭부 및 제 2 스위칭부를, 릴레이 스위치와 병렬로 연결하되, 제 1 스위칭부 및 제 2 스위칭부가 내부에 반도체 스위칭 소자 및 다이오드를 포함하도록 함으로써, 배터리로부터 부하측으로 전원을 공급하는 경우 뿐만 아니라, 배터리로 충전 전류를 공급하여 충전을 수행하는 경우에도 릴레이의 점점에서 스파크 및 아크를 방지하면서 전원을 공급하거나 차단할 수 있다.
