Abstract

The invention discloses a high-voltage power distribution box assembly for a new-energy vehicle. The assembly comprises a box body and a box cover, wherein the box cover is mounted on the box body; a sealing pad is mounted between the box body and the box cover; a manual maintenance switch is mounted at the upper end of the box body; an MSD port is formed in the upper end of the box body; an MCU positive pole connecting port, an MCU negative pole connecting port, a back battery pack connecting port, a front battery pack negative pole connecting port and a front battery pack positive pole connecting port are formed in the left end of the box body; a PTC connecting port, a DC / DC connecting port, an AC connecting port, an OBC connecting port and a signal port are formed in the right end of the box body; and a power distribution unit and a short-circuit protection unit are mounted in the box body. The assembly is high in integration degree, the size of the high-voltage power distribution box assembly is reduced, by the aid of the short-circuit protection unit and the power distribution unit, a short-circuit protection function is realized when a main circuit is overloaded while high-voltage large-current energy transmission control is realized, and the reliability and the safety of a high-voltage electrical control system of the electric vehicle are effectively improved.

Description

technical field [0001] The invention relates to the field of new energy electric vehicles, in particular to a high-voltage power distribution box assembly for new energy vehicles. Background technique [0002] With the increasingly serious environmental problems and energy crisis, new energy vehicles have emerged in this context. New energy 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. Under the current state's inclination towards new energy vehicle policies, various first-tier automakers have launched their own pure electric and hybrid models. [0003] Due to the constraints of cost and technology, traditional electric vehicles often use bolt fastening terminals to realize the connection of various high-voltage systems during high-voltage current transmission. Altho...
