Problems solved by technology

[0002] At present, the grouping methods of new energy power battery packs are mainly divided into two types: the first one is to combine lithium batteries into "finished product" modules, and then group these "finished product" modules to form power battery PACK. The method has about 30% to 40% energy loss, depending on the grouping technology, the loss degree is different, and its advantage is that it can be disassembled and the maintenance cost is low, but the energy conversion rate is low, the grouping efficiency is low, and the production cost is high; the second method , the battery cells are directly bonded to the box with structural glue according to the high-voltage wiring method. This grouping method has about 15% to 20% energy loss. Also according to the different grouping technologies, the degree of loss is different. The advantage of the method is that the energy conversion rate is high, but the maintenance cost of the whole package is high in the later stage. If any single cell has a problem, due to the characteristics of the structural adhesive, the basic battery pack needs to be scrapped as a whole.
[0003] It can be seen that there is currently an irreconcilable contradiction in the design of power battery packs, that is, the contradiction between high energy conversion rate and low maintenance cost
[0004] In addition, the battery pack will generate heat during use, and if there is no good cooling structure, it is easy to cause safety problems

Abstract

The invention discloses a power battery pack structure and an assembly process thereof. The battery pack structure comprises a module; the battery pack structure further comprises a water-cooling boxbody, a protection structure arranged on the water-cooling box body and a module mounting assembly arranged in a protection space formed by the water-cooling box body and the protection structure; andthe module is detachably connected with the water-cooling box body through the module mounting assembly. By optimizing the grouping mode of the battery packs, the battery packs are modularized, and the modules are detachable, so that the later maintenance cost of the battery packs is greatly reduced, and the overall cost of the battery packs is reduced.
