BATON is a robotic workstation that disassembles used EV battery packs from multiple manufacturers and grades each cell for reuse. It works on packs built from cylindrical cells, and the cells it recovers go on to second lives in electric motorcycles, golf carts, and industrial electric vehicles. AI vision reads each pack's bolts, connectors, and cables in real time and determines its disassembly sequence, while Quick-Changer tooling swaps drivers, grippers, and cutters to carry it out. This handling is non-contact and remote-controlled, so no operator works inside an opened pack. A multi-sensor module then measures each cell's voltage, internal resistance, and capacity, and an AI model grades it A, B, or C, with reuse-decision accuracy above 90%. Each cell leaves a traceable digital record. Set against equipment that handles only one of disassembly, measurement, or grading, BATON carries a unit from sealed pack to graded cell in one pass.
