Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery modules, and particularly relates to a lithium battery module. Background Technique

[0002] A lithium battery module refers to a battery assembly formed by combining multiple lithium batteries. It usually consists of battery cells, a protection board, a connector, a bracket and other components, and is connected to a system through an internal or external connector to achieve energy supply.

[0003] For example, the utility model patent with the publication number CN219286503U discloses a lithium battery module, which includes a battery pack, a transfer board, a buffer layer, a buffer pad and a fixing plate. The battery pack and the transfer board are arranged at one end of the battery group; the buffer pad and the fixing plate are arranged on both sides of the battery pack with the buffer layer therebetween, and the buffer layer is arranged in the internal cavity of the battery group and on the side of the battery pack. During the use of the battery pack, the heat generated is conducted to the outside of the battery pack through the insulating buffer layer attached to the periphery of the battery core, improving the consistency of the temperature field of the battery pack, improving the use environment of the battery pack, and enhancing the cycle life of the battery pack; when the battery pack is impacted by an external force, during the impact process, the buffer layer buffers the impact force, reducing the damage caused to the transfer board by the impact force. At the same time, the buffer layer also has a fixing effect on the external transfer board and the fixing plate, filling the internal cavity of the battery pack, thereby enhancing the safety of the battery pack. However, when this lithium battery module is in use, there are still other deficiencies. Since the lithium battery module is a fixed structure, the lithium battery module cannot be effectively spliced to install or disassemble the lithium battery body, and heat is generated during the operation of the lithium battery module, so the lithium battery module does not have a heat dissipation effect. As a result, when the heat accumulates to a certain extent, a thermal runaway phenomenon may occur. Therefore, when using this device, there are still certain deficiencies.
