[0002] An energy storage battery is a device used to store electrical energy and release it when needed, and is widely used in fields such as power grid energy storage, electric vehicles, and renewable energy systems. In order to improve the energy capacity and power output of energy storage batteries, multiple battery cells are usually connected in series and parallel to form a larger battery module. This requires the use of a connection structure to ensure reliable electrical connection between all battery cells and effective transmission of current.

[0003] Chinese Utility Model Patent CN218123590U discloses a highly stable and highly insulating battery fixing structure, which includes a first fixing seat, a second fixing seat, and a third fixing seat placed vertically.

In addition, during the operation of the battery, a large amount of heat is generated, and using a binding strap to fix the side wall of the battery may prevent the normal heat dissipation of the battery, thus bringing potential safety hazards. Content of the Utility Model

[0006] Furthermore, it also includes inclined blocks provided on the protective sheets.

[0011] Further explanation: Threaded sleeves are arranged on both the left and right side walls of the surrounding frame, and circular holes adapted to the threaded sleeves are provided on the side sheath.

[0012] Beneficial effects: Through the snap connection between the lower sheath, the upper sheath and the protection piece, and the adaptation between the side sheath and the positioning protrusion, the utility model forms a stable outer shell structure, which can effectively fix the battery and provide good protection to avoid damage to the battery caused by external impact, and there is enough space between each component for the battery to ventilate and dissipate heat; the design of the snap blocks at the top and bottom of the side sheath further strengthens the connection between the upper and lower sheaths and the side sheath, improving the stability and mechanical strength of the entire outer shell structure; the design of the partition plates in the lower sheath can isolate different battery monomers, facilitating maintenance and replacement, and also supports modular expansion, and the battery capacity can be adjusted according to actual needs; the cooperation between the surrounding frame and the bevel blocks on the protection piece not only increases the integrity of the structure, but also simplifies the assembly process. The design of the threaded sleeves on the surrounding frame and the circular holes on the side sheath can further enhance the stability when the entire structure is connected.
