Problems solved by technology

[0003] The fixing method of the above-mentioned battery module can improve the assembly efficiency, but the connection between the battery module and the box is irreversible, and the battery module cannot be taken out of the box directly. When the battery pack is disassembled mechanically, it is easy to damage the battery module. Batteries lead to the scrapping of parts and waste of resources

Abstract

The invention discloses a battery pack disassembling method. The battery pack disassembling method comprises the following steps of obtaining a battery pack to be disassembled, mechanically cutting a box body of the battery pack, exposing a structural adhesive between battery modules and the bottom of the box body, then smearing a dispergator on the structural adhesive, transferring the battery pack to a low-temperature environment for standing, and finally taking out the battery modules from the box body one by one. In the disassembling process, the structural adhesive in the battery pack is treated in a mode of combining low-temperature standing and coating of a dispergator on the structural adhesive, and the battery module is prevented from being damaged in the disassembling process by weakening the bonding force of the structural adhesive to the battery module; and the box body is mechanically cut, so that the exposed area of the structural adhesive is increased, the coating range of the dispergator is expanded, the bonding force of the structural adhesive to the battery modules is further weakened, and the battery modules can be conveniently taken out from the box body.

Description

technical field [0001] The invention relates to the field of battery recycling, in particular to a battery pack disassembly method. Background technique [0002] The battery pack is composed of a box and a plurality of battery modules accommodated in the box. A layer of structural glue is provided on the bottom of the box, and the battery modules are adhered to the bottom of the box by the structural glue. [0003] The fixing method of the above-mentioned battery module can improve the assembly efficiency, but the connection between the battery module and the box is irreversible, and the battery module cannot be taken out of the box directly. When the battery pack is disassembled mechanically, it is easy to damage the battery module. Batteries lead to the scrapping of parts and waste of resources. Contents of the invention [0004] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a battery pack disassembly method with high...
