Problems solved by technology
Among them, due to the limited number of power batteries of plug-in pure electric vehicles, the mileage of pure electric vehicles is limited. When pure electric vehicles need to travel for a long distance, they must be charged multiple times along the way.
However, the existing plug-in pure electric vehicles generally take more than one hour to fully charge once, and the problem of low charging efficiency cannot be solved for a long time, which has brought a lot of inconvenience to the driver, and has become a constraint for the promotion and promotion of pure electric vehicles.

Description
technical field [0001] The invention belongs to the technical field of power batteries for new energy vehicles, and in particular relates to a quick-change battery pack assembly. Background technique [0002] New energy vehicles, especially pure electric vehicles, have become a hot spot in the development of the automotive industry. Existing pure electric vehicles use power batteries as power sources. Existing pure electric vehicles are mainly divided into plug-in type and quick-change type based on different charging methods. Among them, due to the limited number of power batteries of plug-in pure electric vehicles, the driving range of pure electric vehicles is limited. When pure electric vehicles need to travel for a long distance, they must be charged multiple times along the way. However, the existing plug-in pure electric vehicles generally take more than one hour to fully charge once, and the problem of low charging efficiency cannot be solved for a long time, which ...
