To investigate the application of laser welding in the production of lithium battery modules for electric vehicles, this study employs the finite element method to simulate the welding process of lugs and busbars in lithium batteries under different parameters.
In conclusion, the automation of spot welding between lithium-ion battery cells and sheet metal connectors using an Arduino microcontroller has been successfully implemented. The machine was designed to move in three degrees of freedom to accurately place the welding in the desired location.
The compared techniques are resistance spot welding, laser beam welding and ultrasonic welding. The performance was evaluated in terms of numerous factors such as production cost, degree of automation and weld quality. All three methods are tried and proven to function in the production of battery applications.
1. The heat during the laser welding of lithium battery lugs is distributed centrally within the weld region, resulting in a significant temperature gradient in front of the molten pool and a smaller gradient at the rear. During the cooling process after welding, the temperature decreases rapidly within 5 s.
Therefore, the study of battery welding technology is of great significance for the improvement of connection performance of lithium batteries, process optimization, and process management strengthening of manufacturing engineering.
We found that the the spot welding which is one of the very vital process carried in the manufacturing of lithium ion battery packs is performed manually in most of the small scale Li-ion battery pack manufacturing industries.
