AI Technical Summary

⚠Technical Problem

Existing battery modules are mostly single-module units consisting of a single row of cells and cast aluminum end plates with straps. They occupy a lot of space, are costly, and require multiple end plates and steel strips.

⚗Method used

It adopts a combination structure of multiple rows of battery cells with two end plates and two side plates. It is fixed by flanges and fastening components, which simplifies the operation steps, reduces the number of parts used, and improves the overall strength and seismic resistance by using the fixing method of side plates and end plates.

🎯Benefits of technology

It simplifies the operation steps, reduces production costs, improves production efficiency, enhances the fixing effect and overall strength of the battery cells, extends service life, and optimizes the layout design of the battery module.

Abstract

The application relates to the technical field of batteries, in particular to a battery module and an energy storage battery module. The battery module comprises a plurality of battery cell assemblies, two end plates and two side plates. The plurality of battery cell assemblies are sequentially arranged along a first preset direction, and each battery cell assembly comprises a plurality of battery cells sequentially arranged along a second preset direction. The plurality of battery cell assemblies are collectively connected to the two end plates along the second preset direction, and the two end plates are arranged at opposite ends of the plurality of battery cell assemblies. Along the first preset direction, the two side plates are arranged at opposite sides of an assembly of the plurality of battery cell assemblies and the two end plates, and the two side plates are connected to the two end plates. As can be seen, the plurality of rows of battery cells are collectively connected to the two end plates and the two side plates to form a group, and the battery cells do not need to be separately grouped and then assembled, so that the operation steps are simplified, the production efficiency is improved, the investment in parts is saved, and the production cost is reduced.
