Description

Technical Field

[0001] The utility model relates to the technical field of battery modules, in particular to a standardized battery module. Background Art

[0002] A battery module contains several battery cells. It is essentially a bracket system consisting of a casing, a battery cell, a terminal cover and other parts. They are combined together to form an integral battery pack, providing a modular and scalable solution for the battery system. It is widely used in electric vehicles, energy storage systems, portable electronic devices and other fields.

[0003] According to a square aluminum shell battery cell CTP solution module proposed by announcement number: CN216250946U, the overall weight of the battery module is effectively reduced by using longitudinal pressure strips, transverse pressure strips and side pressure strips to replace traditional side panels to connect and fix the battery cells. The transverse pressure strips and side pressure strips are connected and fixed to the end plates to press the longitudinal pressure strips onto the battery cells. This makes it unnecessary for the device to fix the battery cells through steel strips or brackets, reduces the types of materials used in production, and is beneficial to production. Compared with traditional side panels, the pressure strips have the advantage of being easier to process, are suitable for fixing a variety of battery cells, and have good general performance.

[0004] According to the above introduction, the battery module cannot be hoisted, which affects the movement and packing process of the battery module. At the same time, the components in the battery module are not convenient to disassemble and assemble, which reduces the versatility of the components and cannot adapt to more different types of plug-in boxes. In addition, the existing form of pressure strips is not strong enough, and the internal insulation treatment of the battery cell is not performed, which will affect the battery cell. In order to solve the above problems, we propose a standardized battery module. Utility Model Content
