Problems solved by technology

In the prior art, the manual maintenance switch is generally connected to the battery pack and the high-voltage interlock circuit, and the operation safety is low; and the manual maintenance switch has a certain volume and weight, which makes the space size of the battery pack higher, which is not conducive to the battery pack as a whole. Increased energy density; in addition to this, it also results in increased costs and increased difficulty in maintenance operations

Abstract

The invention provides a battery pack assembly, which includes a battery pack, a power distribution module and a manual maintenance switch. The power distribution module is arranged on the battery pack. The bottom of the groove is electrically connected with the power distribution module, and the plug is inserted into the socket to set the manual maintenance switch at least partly in the installation groove; the invention also provides a car; the battery pack assembly provided by the invention, the manual maintenance switch is integrated in the On the power distribution module, it can reduce the difficulty of assembly, reduce installation consumption and reduce costs; and by inserting or unplugging the plug, the high-voltage and low-voltage circuits inside the power distribution module can be turned on or off at the same time, and the operation is simple; in addition In addition, since the high-voltage circuit and low-voltage circuit and the battery pack casing can only be disconnected after the plug is pulled out, it is beneficial to avoid potential safety hazards caused by operator errors and greatly improves safety.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a battery pack assembly and a vehicle. Background technique [0002] With the rapid development of the automobile industry and the continuous improvement of people's living standards, the demand and holdings of automobiles are also increasing. Automobiles are not only an important means of transportation, but also an important means of transportation in people's daily life. With the increasing shortage of non-renewable resources such as oil, people pay more and more attention to the development of new energy vehicles. New energy vehicles refer to vehicles powered by clean energy, including electric vehicles, fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles, etc. Among them, electric vehicles have been rapidly developed due to the advantages of lithium batteries such as low self-discharge rate, long storage life, no memory effect, small size, l...
