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 laser welding of the lugs refers to the laser overlay welding of the lugs and the busbar, in which there are two types of materials for the lugs, namely 1060 aluminium alloy and TU1 oxygen-free copper, and the material for the busbar is 6061 aluminium alloy. The main chemical compositions of the materials are shown in Table 1.
The boundary condition is the convective heat transfer between the surface of the lugs and the busbar in the welding process, and the surface convective heat transfer coefficients between the lugs and the busbar and the surrounding environment are calculated as shown in Table 2.
