The stability, safety, and ease of operation of the storage process directly affect battery lifespan, energy storage system operating efficiency, and maintenance costs. With the diversification of battery application scenarios (such as centralized storage in large-scale energy storage power stations, distributed storage in distributed devices, and portable storage in mobile devices), the functional requirements for battery storage structures are becoming increasingly detailed: they need to achieve the orderly storage of batteries of different specifications (such as single cells or battery packs of different sizes and capacities), ensuring that batteries are not subjected to collisions, compression, or environmental interference during storage; at the same time, batteries need to be easily accessible during installation, replacement, and testing to reduce operational complexity and avoid battery damage or low maintenance efficiency caused by inconvenient access.

[0003] The placement units of existing storage structures are mostly fixedly connected to the main structure or lack convenient moving guide design.

Push the support element 133 so that it moves away from the main body element 111 along the length direction of the groove element 122 via the moving element 132, so that the first placement element 131 and the second placement element 134 leave the interior of the main body element 111; The battery is placed in the first placement element 131 and the second placement element 134; Push the bracket element 133 to move the first placement element 131 and the second placement element 134 containing the battery along the length direction of the groove element 122 towards the main body element 111 via the moving element 132, so that the first placement element 131 and the second placement element 134 containing the battery enter the interior of the main body element 111.

[0084] (II) Testing Operations The usage method is basically the same as that in (I), so I will not repeat it here.

[0085] The advantages of this invention are that the cooperation between the main unit, the guide unit, and the placement unit brings convenience to battery retrieval and placement. The placement unit and the guide unit slide together, which can directly drive the battery in and out of the main unit without the need for manual handling of the battery through narrow areas, avoiding battery bumps and damage and improving maintenance efficiency. The locking unit provides a locking effect for the placement unit, which can restrict the movement of the placement unit through a detachable connection, preventing the placement unit from sliding and causing battery damage, and improving the reliability of battery storage.
