The present invention relates to a power relay assembly for an electric vehicle and a driving method thereof, and more particularly, to a power relay assembly for an electric vehicle capable of performing a precharge process by replacing a gas charging type relay used as a precharge relay with a semiconductor switch, and a driving method thereof. Also, the present invention can perform the precharge process by replacing the conventional gas charging relay with the semiconductor switch by including a main relay, the precharge relay composed of a semiconductor switching element, a gate voltage supply unit for turning on the precharge relay before the main relay is turned on and turning on the precharge relay before the main relay is turned off, by using a gate voltage, and a control unit for controlling the gate voltage supply unit.

    본 발명은 전기 차량용 파워릴레이 어셈블리 및 이의 구동방법에 관한 것으로, 구체적으로는 프리차지 릴레이로 사용되는 가스 충전식 릴레이를 반도체 스위치로 대체하여 프리차지 과정을 수행하는 전기 차량용 파워릴레이 어셈블리 및 이의 구동방법에 관한 것이다. 또한, 본 발명은 메인 릴레이와, 반도체 스위칭 소자로 이루어지는 프리차지 릴레이와, 게이트 전압을 공급하여 메인 릴레이가 턴온되기 전에 프리차지 릴레이를 턴온하고 메인 릴레이가 턴오프되기 전에 프리차지 릴레이를 턴온하는 게이트 전압 공급부와, 게이트 전압 공급부를 제어하는 제어부를 구비하므로, 기존의 가스 충전식 릴레이를 반도체 스위치로 대체하여 프리차지 과정을 수행할 수 있다.
