Abstract

The invention relates to a split type high-voltage distribution box of a pure electric vehicle, which belongs to the technical field of electric vehicles and comprises a first high-voltage distribution box and a second high-voltage distribution box, wherein the first high-voltage distribution box is embedded in a battery pack, the first high-voltage distribution box comprises an insulating sheathshell, a relay and an external output port, the relay and the external output port are positioned in the insulating sheath shell, and the insulating sheath shell is provided with a mounting hole for extending out of the external output port; the second high-voltage distribution box is embedded into the battery pack, the second high-voltage distribution box comprises an insulating shell, an electric conductor and a rear-drive motor interface, the electric conductor and the rear-drive motor interface are arranged in the insulating shell, a fuse cover plate is arranged on the insulating shell, afuse is arranged in the fuse cover plate, the fuse is connected with the electric conductor, and the electric conductor is electrically connected with the battery pack. The first high-voltage distribution box and the second high-voltage distribution box are respectively embedded into the battery pack and are connected with the battery pack into a whole, so that the distribution box has the advantages of light weight, space saving, compact structure and low cost.

Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to a split-type high-voltage power distribution box for pure electric vehicles. Background technique [0002] With the gradual application and popularization of electric vehicles, the development of electric vehicles is getting faster and faster, and the functional requirements of electric vehicles are also getting higher and higher. Electric vehicles are mainly powered by the battery system, and the energy transmission of the entire system is carried out by the high-voltage electrical system. The high-voltage power distribution box is the core component of the high-voltage electrical system of electric vehicles. Its main function is to control the on-off of the internal high-voltage relay through the external low-voltage control circuit, and to drive the high-voltage DC power supply of the power battery according to the internal design circuit of the high-voltag...
