The present invention relates to an electric power distributor for an electric vehicle, wherein a fuse and a relay are connected to correspond to one to one in components to be controlled, such as a battery disconnect unit (BDU), a power control unit (PCU), or a positive temperature coefficient heater (PTC). Therefore, each of the components to be controlled is controlled to be fitted to characteristics of the components to prevent the components from being damaged or broken. Moreover, when an abnormal current such as an overcurrent flows, the overcurrent is prevented from being applied to a positive temperature coefficient heater by resistance to block the overcurrent to more improve stability of an electric vehicle.
본 발명은 전기차용 전력 분배 장치에 관한 것으로, BDU(Battery Disconnect Unit)나 PCU(Power Control Unit) 또는 PTC(Positive Temperature Coefficient Heater)와 같은 제어대상 부품들에 퓨즈와 릴레이를 일대일 대응되게 연결시킴으로써, 각 제어대상 부품의 특성에 맞는 제어를 통해 부품의 손상이나 파손을 억제시킬 수 있는 효과와, 과전류와 같은 이상전류가 흐르는 경우에도 상기 과전류차단 저항에 의해 과전류가 정온도계수 히터에 부과되는 것을 억제시킴으로써, 전기차 시스템 안전성을 더욱 높일 수 있는 효과를 기대할 수 있게 한다.
