Robotic Flexible Disassembly Technology and Applications for Retired EV Battery Packs

Abstract: Retired EV battery packs contain diverse irregular components, hierarchical internal structures, and complex assembly connections. Traditional manual disassembly is labor-intensive, risky, inefficient, and inconsistent, making it difficult to meet the requirements of large-scale, refined, and intelligent recycling. This report focuses on the demand for efficient and safe recycling of used battery packs of new energy vehicles, independently developed a dual-arm robot flexible disassembly system for the irregular components of used battery packs, proposed a visual recognition and positioning model integrating disassembly topological relationships and a disassembly sequence planning method integrating spatial geometry, gravity, friction force and the operability constraints of the robot, and achieved the refined disassembly of the battery packs. The related technologies have been verified in typical whole-pack disassembly tasks of used battery packs, providing technical support for the robotic disassembly of used battery packs.
