Therefore, how to improve the rapid installation and disassembly capability of the battery pack has become one of the important directions of the current battery technology development.

[0003] The existing battery pack adopts traditional modular design, that is, the battery unit (Cell) is first composed into a module (Module), and then assembled into a battery pack (Pack). Although this method ensures the flexibility of battery management to a certain extent, due to the additional module structure, it leads to low space utilization, large number of parts, high manufacturing cost, and at the same time increases the volume and weight of the battery pack, which limits the miniaturization and light weight of the equipment. In order to solve this problem, CTP (Cell to Pack) technology emerges as the times require, which omits the module link and directly integrates the battery core into the battery pack, thereby improving the energy density, improving the grouping efficiency of the battery system, and reducing the manufacturing cost.

[0004] However, the existing CTP technology mainly focuses on improving the energy density and structural integration of the battery, and still has certain limitations in the rapid replacement and installation convenience of the battery pack. For example, the fixing method of the traditional CTP battery pack often adopts a bolt structure, which is relatively cumbersome to disassemble and assemble, and is not convenient for daily maintenance and battery replacement of the equipment. At the same time, frequent replacement of the battery may cause mechanical fatigue or damage to the connection, thereby affecting the service life. In addition, the installation of the traditional battery pack usually requires professional tools and a long disassembly and assembly time, which cannot meet the needs of high-efficiency and frequent replacement application scenarios.
