Problems solved by technology

Due to the use of hardware brackets in this solution, the battery pack is bulky as a whole, and its mass and volume are large. Not only does the battery system have more components, the production process is complicated, and the cost is high. It also makes the battery pack occupy a larger space and have a higher center of gravity.

Abstract

The invention relates to the technical field of batteries, and discloses a battery pack and an assembly process of the battery pack. Thebattery pack comprises a lower box body; a bottom layer module which is arranged in the lower box body; a laminated module arranged on the bottom layer module in a stacked mode; an elastic cushion which is arranged between the laminated module and the bottom layermodule in a clamping manner; a connecting piece which sequentially penetrates through the laminated module and the bottom layer module and is connected to the lower box body, wherein the laminated module and the bottom layer module are connected to the lower box body through the connecting piece. By means of the structure, the battery pack has the advantages of being smaller in mass, lower in overall height and smaller in occupied space.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack and an assembly process for the battery pack. Background technique [0002] In recent years, with people's increasing emphasis on environmental protection and the rapid development of the new energy industry, power batteries have been rapidly extended from electric vehicles to rail transit, shipping, industrial docks, storage and transportation, household power supplies and other fields. [0003] At present, in order to improve the battery life of power batteries, battery manufacturers have begun to compress the space occupied by battery packs, and battery modules have also begun to be stacked to two, three, or even more layers. The commonly used method for this process is to first lock the bottom module on the box body with bolts, then use bolts to lock the hardware bracket on the box body, and then use bolts to lock the battery modules with two or more layers ...
