Description

Technical Field

[0001] This utility model belongs to the field of battery recycling technology, and specifically relates to a battery pack disassembly device. Background Technology

[0002] The battery pack consists of a main casing and multiple battery modules arranged in an orderly fashion within it. To ensure the battery modules are securely placed within the casing, a layer of structural adhesive is applied to the bottom of the casing. This adhesive firmly bonds the battery modules to the bottom of the casing.

[0003] When recycling battery packs, the cells of the recycled battery packs can undergo a series of rigorous testing and repair processes before being put back into fields such as energy storage systems and low-speed electric vehicles, where battery performance requirements are relatively low, thus achieving the recycling of resources.

[0004] Because the battery module is tightly bonded to the casing with structural adhesive, it's impossible to remove the battery module directly from the casing without damage. When the battery pack needs to be recycled, mechanical disassembly can easily damage the battery cells inside the module during separation due to the strong adhesion of the structural adhesive. As the most critical and vulnerable component of the battery module, damage to the cells can jeopardize the entire module's functionality, ultimately rendering it unusable and resulting in resource waste during recycling. This negatively impacts the recycling and reuse of battery packs. Utility Model Content
