Problems solved by technology

In the prior art, the high-voltage distribution box is usually placed in the battery pack box together with the power battery, and the battery pack box is closed after the wire connection in the battery pack box is completed. Therefore, when the high-voltage distribution box fails or When it needs to be replaced, the battery pack box needs to be opened, which will not only affect the airtightness of the battery pack, but also the maintenance and replacement process is cumbersome and complicated, making it difficult to maintain the high-voltage distribution box

Abstract

The invention provides a battery pack and an electric vehicle. The battery pack comprises a box body, a power distribution box and a plurality of pole core strings, wherein the plurality of pole core strings are located in the box body and are electrically connected with one another to form an energy storage assembly, the power distribution box is installed on the outer side surface of the box body, and the power distribution box is electrically connected with the pole core strings in the box body to realize a power distribution function. Therefore, the power distribution box is installed outside the box body, so that when the power distribution box breaks down or needs to be maintained, the box body does not need to be opened, the power distribution box can be directly operated outside the box body, the tedious operation process can be avoided, the process is simplified, and the power distribution box is convenient to maintain.

Description

technical field [0001] The invention belongs to the field of batteries, in particular to a battery pack and an electric vehicle. Background technique [0002] Electric vehicle high-voltage distribution unit (Power Distribution Unit, PDU) is a high-voltage power distribution unit for pure electric vehicles and plug-in hybrid vehicles. Its function is to ensure the transmission of power and electric energy in the vehicle system. The bridge for the power supply and electrical signal transmission of various high-voltage equipment. In the prior art, the high-voltage distribution box is usually placed in the battery pack box together with the power battery, and the battery pack box is closed after the wire connection in the battery pack box is completed. Therefore, when the high-voltage distribution box fails or When it needs to be replaced, the battery pack box needs to be opened, which will not only affect the airtightness of the battery pack, but also the maintenance and repla...
