The automatic disassembly of electric vehicle battery has always been a key issue in the field of electric vehicle battery recycling. This paper proposes an optimal strategy of disassembly process in electric vehicle battery based on human-machine collaboration re-manufacturing, which combines with artificial intelligence algorithms to complete the identification and positioning of operational targets, optimize the sequence of man-machine operation tasks, and improves the efficiency and safety of the disassembly process. Finally, the research prospects for the implementation of the overall strategy and the future development direction are proposed.
