The consistency of the single batteries is considered, the retired power battery modules are not split into single batteries for screening and matching, the battery modules are taken as objects for screening and matching, and the battery modules with good consistency of the single batteries are matched through judging open-circuit voltage of the single batteries. The work difficulty of cascade utilization of the matched batteries is greatly simplified, and the screened and matched power battery packs are short in production cycle, relatively high in consistency and low in manufacturing cost.

Method for welding thin steel plate
InactiveCN101745718AAvoid deformationShort production cycleArc welding apparatusSteel platesSheet steel
The invention discloses a method for welding a thin steel plate. The method is characterized by comprising the following steps: preparing before welding, namely flattening the plate before assembly to flatten the surface of the plate; flattening a profile before assembly; and machining edge-board blanking by adopting an edge planer or cutting the blanking by plasma to ensure uniform assembly clearance. During arc welding of the jointed plate, the assembly clearance is less than 0.5 millimeters; the misalignment edge e of the plate edge is less than 0.15t, and the nonuniform or out-of-tolerance local clearance is polished or cut to be smooth without deformation due to the adoption of oxy-acetylene cutting, wherein the t is less than or equal to 8 millimeters; the three parts of positioned welding and welding are reasonably designed, so the welding of the thin steel plate has a complete system; therefore, the method can effectively prevent the thin steel plate of a ship deck from deforming during welding, and achieves the targets of short production period and good thin plate welding quality.
