The embodiment of the invention provides a power distribution circuit, a circuit board, a power distribution box and an electric vehicle. The power distribution circuit comprises a vehicle-mounted charger amp; a DC converter, a first connector, a second connector, a first fuse, a second fuse, and a first position; the first position comprises two ends which are not connected with each other; a vehicle-mounted charger amp; the output positive electrode of the direct-current converter is electrically connected with the first end of the first fuse, and the second end of the first fuse is electrically connected with the first end of the first connector and the first end of the second fuse; the second end of the second fuse is electrically connected with the first end of the first position; the second end of the first position is electrically connected with the first end of the second connector; a vehicle-mounted charger amp; the output negative electrode of the direct-current converter is electrically connected with the second end of the first connector and the second end of the second connector; the first position is used for accessing a first relay or accessing a first copper bar. The high-voltage power distribution box can meet power distribution requirements of various different vehicle types, and customized development of the high-voltage power distribution box and an internal circuit board thereof is reduced.
本发明实施例提供一种配电电路、电路板、配电盒和电动汽车,配电电路包括:车载充电器&直流变换器、第一连接器、第二连接器、第一熔断器、第二熔断器、第一位置;第一位置包括2个互不连接的端;车载充电器&直流变换器的输出正极和第一熔断器的第一端电连接,第一熔断器的第二端与第一连接器的第一端、第二熔断器的第一端电连接;第二熔断器的第二端和第一位置的第一端电连接;第一位置的第二端和第二连接器的第一端电连接;车载充电器&直流变换器的输出负极和第一连接器的第二端、第二连接器的第二端电连接;第一位置用于接入第一继电器或接入第一铜排。能够适配多种不同车型的配电需求,减少高压配电盒及其内部电路板的定制开发。
