The present invention relates to a power relay assembly for an electric vehicle and, more specifically, to a power relay assembly for an electric vehicle, which has an excellent thermal radiation property since a metal core printed circuit board (PCB) and a circuit pattern are applied thereto, has reduced weight and size, facilitates composition of a circuit, and can block a back electromotive force by having a back electromotive force prevention device. According to an embodiment of the present invention, the power relay assembly for the electric vehicle includes electric components such as a main relay, a precharge relay, and a precharge resistor. The power relay assembly for the electric vehicle also includes: the metal core PCB having an insulation layer on the upper surface or the lower surface of a metal core layer, wherein the electric components are installed on one side of the metal core PCB and the metal core layer formed with a metal board is formed therein. The circuit pattern supplying a current by connecting the electric components is formed on the upper surface or the lower surface of the metal core PCB.

    본 발명은 전기자동차 파워 릴레이 어셈블리에 관한 것으로, 보다 상세하게는 메탈 코어 PCB 및 회로패턴이 적용되어 방열성이 우수하고, 무게 및 크기가 감소하며, 회로구성이 용이하고, 역기전력 방지 소자가 구비되어 역기전력이 차단될 수 있는 전기자동차 파워 릴레이 어셈블리에 관한 것이다. 본 발명의 일 실시예에 따른 전기자동차 파워 릴레이 어셈블리는 메인 릴레이, 프리차지 릴레이, 프리차지 저항 등의 전기부품들을 포함하는 전기자동차 파워 릴레이 어셈블리에 있어서, 일면에 상기 전기부품들이 설치되고, 내부에는 금속 판재로 구성되는 금속 코어층이 형성되며, 상기 금속 코어층의 상면 또는 하면에는 절연층이 형성되는 메탈 코어 인쇄회로기판을 포함하고, 상기 메탈 코어 인쇄회로기판의 상면 또는 하면에 상기 전기부품을 연결하여 전류를 공급하는 회로패턴이 형성되는 것을 특징으로 한다.
