Electric vehicle (EV) module and pack (M&P) systems are assembled by both OEMs as well as automotive makers. A module is composed of a few cells welded or otherwise physically attached to each other. Multiple battery cells are assembled into a module, wrapped in steel plates, and have their poles welded together to produce the correct voltage. A pack of batteries contains several modules placed in a single container for thermal management. Inspection during the module and pack assembly process ensures that both cells and modules are in the correct position, have strong contact, and are properly welded. Cognex offers machine vision solutions for module inspection, busbar welding inspection, M&P assembly, cable connector guidance, and code reading to guarantee proper function before EV modules and battery packs flow into general assembly.
