Electric automobile high voltage power distribution box

The invention provides an electric automobile high voltage power distribution box which comprises a box body, a main control box, an insulating controller and a power management controller. The box body is provided with a fuse wire, a PCB plate and high voltage output ports connected with the PCB plate, and an electronic switch control circuit module is arranged on the PCB plate. According to the electric automobile high voltage power distribution box, the electronic switch control circuit module is used to replace a high voltage direct current contactor in the prior art; the defect that the high voltage power distribution box is large in size, high in cost and short in life due to the fact that high voltage direct current contactor exists is overcome; wiring harness arrangement between devices in the high voltage power distribution box is further optimized; the ability of the box body to resist electromagnetic interference is strengthened; the size of the box body is reduced; the whole automobile space is sa
