General electric automobile high voltage distribution box

The utility model relates to a general electric automobile high voltage distribution box which comprises a box body. A power battery interface, a motor controller interface and a distribution main circuit are arranged on the box body, a plurality of distribution branches connected onto the power battery interface are arranged in the box body, and each distribution branch is connected with an expansion distribution interface on the box body. A pre-charging circuit is arranged on the distribution main circuit, the distribution main circuit and the distribution branches are all in series connection with fuse wires and distribution relays, a communication interface is arranged on the box body and is in electric connection with a controller, and the distribution relays are in electric connection with the controller. The expansion distribution interfaces comprise more than two frequency conversion interfaces, and frequency converters are connected onto the frequency conversion interfaces. The expansion distribution interfaces further comprise a positive temperature coefficient (PTC) heating interface, a direct current to direct current converter (DCDC) interface and a power air conditioning interface. The general electric automobile high voltage distribution box reasonably distributes power according to various existing automobile models, is complete in function and strong in generality, and enhances power use safety. The whole distribution box is simple in structure and convenient to use.
