The invention belongs to the technical field of new energy electric vehicle high-voltage distribution boxes, and relates to a high-voltage distribution box and a high-voltage distribution box electric vehicle, and the high-voltage distribution box comprises an upper cover, a box body, a base plate and a main drive power supply loop. The main drive power supply loop comprises a first main drive relay, a second main drive relay, a first pre-charging resistor, a first fuse, a first main drive copper bar and a second main drive copper bar, the first main drive relay is connected with the first positive pole copper bar and the first main drive copper bar, and the first end of the first fuse is connected with the first main drive copper bar; the second main drive copper bar is connected with the main drive power supply anode interface and the second end of the first fuse; the second main drive relay is connected with a second positive pole copper bar and the first end of the first pre-charging resistor, and the second end of the first pre-charging resistor is connected with the first end of the first fuse. According to the high-voltage distribution box, the fuse, the relay and the pre-charging resistor are used at the same time, the pre-charging resistor can damage high-voltage electrical elements due to overlarge short-circuit current, the maintenance is convenient, and economic benefits are high.
