In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0054] In the prior art, artificial disassembly of unqualified battery cells in the battery pack is usually adopted, but artificial disassembly makes the disassembly and cutting efficiency low, and other qualified battery cells are easily damaged in the disassembly process, reducing the cutting precision.

[0055] To solve the above problems, the present embodiment provides a battery pack splitting device, as shown in Figure 1 The battery pack splitting device comprises a bearing mechanism 1, a cutter mechanism 2, and a driving mechanism 3. The bearing mechanism 1 comprises a bearing plane for bearing a battery pack 200 to be split. The cutter mechanism 2 is used for cutting the adhesive between two adjacent battery cells 210 in the battery pack 200. The driving mechanism 3 comprises a first driving assembly 31 and a second driving assembly 32. The first driving assembly 31 is drivingly connected to the cutter mechanism 2 and is configured to drive the cutter mechanism 2 to move in a first direction (left-right direction in the figure) so that the cutter mechanism 2 is opposite to the adhesive between the two adjacent battery cells 210 to be split. The second driving assembly 32 is drivingly connected to the first driving assembly 31 and is configured to drive the first driving assembly 31 to move in a second direction (front-rear direction in the figure) towards or away from the battery pack 200.

The cutter assembly 23 is connected to the output end of the lifting driving assembly 22. The lifting driving assembly 22 is configured to drive the cutter assembly 23 to move up and down in a third direction (up-down direction in the figure).
