The embodiment of the invention discloses a battery pack disassembly line. The battery pack disassembly line comprises a transmission main line, a plurality of carrying plates, a feeding mechanism, aliquid pumping mechanism, a plurality of disassembly mechanisms, a plurality of detection mechanisms and a plurality of transmission branches, wherein the carrying plates are arranged on the transmission main line, the feeding mechanism, the liquid pumping mechanism and the disassembly mechanism are sequentially arranged along a transmission direction of the transmission main line, the detection mechanisms and the disassembly mechanisms are arranged in one-to-one correspondence, and three of the transmission branches are arranged asides each disassembly mechanism. Compared with the prior art,the battery pack disassembly line has the following beneficial effects that all processes, namely cooling liquid pumping, multi-stage disassembly, detection and classification, of disassembly a battery pack can be achieved by the battery pack disassembly line, no transfer is needed on a plurality of assembly line, the labor intensity of a worker is reduced, and moreover, the disassembly efficiencyis improved.
