Description

Technical Field

[0002] Power batteries refer to batteries used to drive electric vehicles. Their main characteristics are the ability to provide high power output and long-term continuous use. Secondary utilization refers to the hierarchical use of the same resource according to different needs, thereby maximizing resource utilization benefits. In the field of power batteries, secondary utilization can regenerate and reuse used batteries, thereby reducing resource waste and environmental pollution. When performing secondary utilization, the battery cells of the used battery pack need to be disassembled, and the usable battery cells are screened out. The battery cells are paired and reassembled into power battery packs, which can be used in situations with lower performance requirements, realizing the secondary utilization of power batteries.

[0003] After long-term use, the power battery pack will experience deformation of the box, which makes it inconvenient to disassemble the battery cells. The disassembly and assembly process is time-consuming and labor-intensive, and labor costs are greatly increased. When reassembling the battery cells, since the battery cell structures are not exactly the same, special mounting frames need to be specially designed and processed for battery cells of different specifications, which increases production costs.
