Spot welding is the preferred method for professional battery pack assembly, offering superior safety, performance, and reliability, especially for high-current applications.
In this article, we will discuss multiple welding methods from resistance welding to laser welding technologies and see when one is better suited over another. To join cells into a battery pack, the cell terminals are welded together in serial or parallel to achieve either a higher voltage, higher capacity, or both.
The most crucial aspect to consider when welding a battery pack is the contact resistance between the cell and the connection tab or a buss bar. This variable needs to be minimized to prevent unnecessary energy loss in the form of heat generation.
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.
Resistance welding Resistance welding is the most cost-effective method to weld battery tabs, using both DC inverter closed loop and capacitor discharge power supplies.
The search was then performed using Uppsala University's Library database and Google scholar which cover a wide range of articles and sources. Three methods for welding batteries were given in the template, being laser beam-, ultrasonic-, and resistance spot welding.
The micro-TIG is used for butt, fillet, and lap welds very effectively, and it can go beyond the 0.02″ thick copper without problems. But, it's interesting to note that there are no reports of micro-TIG welding in the manufacturing of electric vehicles battery packs.
In the power lithium-ion battery welding process, technicians select the appropriate laser and welding process parameters based on battery material, shape, thickness, tensile requirements, and more to establish reasonable welding process parameters.
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.
Lithium batteries are welded using the autogenous welding process, which does not require any filler material. This process ensures that the electrodes are welded together correctly.
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.
The temperature field is simulated with varying welding heat inputs to examine the distribution of stress during welding and residual stress patterns in the weldments, as well as the deflection of the weldments under different welding parameters.
