Abstract: 실시예는 전기 자동차의 고전압 릴레이 다중 제어 시스템이 적용된 전력분배장치에 관한 것이다. 
구체적으로, 이러한 전력분배장치는 차량측 주 제어기가 하드-와이어 I/O를 통한 전력분배장치 내부의 고전압릴레이를 직접 제어하는 것을 보조하는 방식(즉, “직접 제어 보조”)과, 이 직접 제어에 더해서 차량 내부 통신을 통한 차량측 주 제어기의 고전압릴레이 제어명령을 사용한 간접 제어도 사용되는 것을 보조하는 방식(즉, “직/간접 제어 보조”)을 통합적으로 수행함으로써, 고전압 릴레이 다중 제어를 수행한다. 
참고적으로, 상기 직접 제어와 간접 제어는 기존의 방식으로 이러한 전력분배를 할 경우, 차량측 주 제어기에서 제어를 수행함으로써 다양하게 전력분배를 제어한다. 그리고, 이러한 고전압 릴레이 다중 제어는 이러한 제어에 추가적으로 나온 것이다.   
그리고, 이때 이러한 전력분배장치는 직접제어를 보조 할 경우, 내부제어기에서 하드-와이어 I/O를 통한 제어전압을 감시해서, 이상이 발생 될시에 릴레이 차단을 순간적으로 지연시키는 기능을 가지므로, 릴레이의 순간적인 차단을 해소함으로써 이루어진다. 
이에 더하여, 이러한 전력분배장치는 직/간접 제어를 보조할 경우, 내부제어기에서 차량측 주 제어기의 직접제어 상태와 간접제어 명령을 상호 비교하여 한쪽 제어가 잘못 되었을 때, 차량측 주 제어기에 문제가 발생한 것으로 판단하고 릴레이 차단을 순간적으로 지연시키는 기능을 가지므로, 릴레이의 순간적인 차단을 해소함으로써 된 것을 특징으로 한다. 
따라서, 이를 통해 전기 차량의 전력분배가 될 시에, 차량에 이상이 발생하거나 주변 환경에 의해 릴레이 전원의 전압강하가 초래되어 릴레이 접점에서 채터링 현상이 발생되므로, 이에 의한 순간 승압과 PDU 내부 또는 고전압 부품의 손상을 방지한다. 
또는, 더 나아가서 의도하지 않은 릴레이 작동 정지로 구동장치에 전력이 차단되어 차량이 비정상적으로 멈추는 것을 방지한다.
