Customer ServiceWelding is a vitally important family of joining techniques for EV battery systems. A large battery might need thousands of individual connections, joining the positive and negative terminals of cells together in combinations of parallel and series blocks to form modules and packs of the required voltage and capacity.
Moreover, the high-volume production requirements, meaning the high number of joints per module/BP, increase the absolute number of defects. The first part of this study focuses on associating the challenges of welding application in battery assembly with the key performance indicators of the joints.
Of these, laser and ultrasonic welding processes dominate in EV battery manufacture – with laser welding the preferred solution for mass production – and continue to be improved and refined. “We see a lot of laser welding and ultrasonic wedge bonding for the larger packs,” says Boyle at Amada Weld Tech.
Process optimisation is by far the most researched area of quality assurance for battery welding applications. Most of the studies have been carried out either as pure experimental investigations to find the process parameters that optimise one or more KPIs of a joint, suppress defects, or validate a process model.
Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.
Laser welding is significantly faster showing the allure of the laser for battery module welding. Cycle time can be reduced even further with the use of a galvo scanning system, where some motion is handled by quick motions in the galvo head, and then indexed after all cells within the welding field are addressed.
