AI Technical Summary
⚠Technical Problem
In existing small power battery packs, the tabs of adjacent cells are usually connected by welding, which makes it difficult to replace individual cells when they are damaged, increases maintenance costs, and affects the performance and safety of the battery pack.
⚗Method used
The traditional welding method is replaced by a crimping assembly and electrode tab crimping. The crimping assembly is electrically connected to the conductor, and the connection is detachable through a locking component, which enables the battery cell to be detached and replaced.
🎯Benefits of technology
It improves the reliability and stability of circuit connections, simplifies the cell replacement process, reduces maintenance costs, and extends the lifespan of the battery pack.

Abstract
The application belongs to the technical field of batteries, and discloses a battery pack and an electric device. The battery pack comprises at least one battery group. The battery group comprises a plurality of battery cells arranged along a first direction. The battery cells have two tab terminals arranged at intervals along a second direction. The first direction intersects the second direction. A first support member is arranged above the battery group. The first support member is provided with a crimping assembly. The crimping assembly is arranged in one-to-one correspondence with the tab terminals. The crimping assembly is electrically connected with the tab terminals. The battery pack realizes electrical connection by means of crimping assembly and tab terminal crimping cooperation, avoids circuit connection problems caused by poor welding, facilitates disassembly and replacement of the battery cells, and improves the service life of the battery pack.
