The invention discloses a high-voltage power supply distribution box assembly which includes a box body and a box cover which are in sealed connection. The inner portion of the box body is provided with a control unit, a pre-charging unit, and a short-cut protection and power distribution unit. The control unit includes a main relay. The pre-charging unit includes a pre-charging relay and a pre-charging resistor. The short-cut protection and power distribution unit includes a converging switching sheet, a subcircuit short-cut protection device and a subcircuit relay. The main relay has a positive electrode connected to a positive electrode of the pre-charging relay. The pre-charging relay has a negative electrode connected to one end of the pre-charging resistor. The other end of the pre-charging resistor is connected to a negative electrode of the main relay. The negative electrode of the main relay is connected to the subcircuit short-cut protection device and the subcircuit relay via the converging switching sheet. The assembly has a high safety performance and a high integration.
