There are many parts that need to be connected in the battery system, and welding is often the most effective and reliable connection method. Laser welding has the advantages of non-contact, high energy density, accurate heat input control, and easy automation, which is considered to be the ideal choice for electric vehicle battery manufacturing.
Battery Laser Welding for Battery Pack Manufacturing Laser welding is one of the most promising joining technologies for EV batteries and energy storage systems. It provides the speed and precision needed to make the thousands of welds that connect tabs and busbars in battery packs, modules, and cells.
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.
All types of battery cells can be laser welded, including cylindrical cells, prismatic cells, and pouch cells. Laser welding is being implemented for a wide range of electric battery applications: With more than 6kW of laser power, the welding speed can be scaled to meet short cycle time requirements.
Laser welding can be optimized for minimal heat input. As a result, batteries do not suffer from excessive heating and maintain better mechanical properties. Lasers can weld dissimilar materials with varying fusion temperatures without the need for filler material. Examples include steel-copper, steel-aluminum, aluminum-copper, and steel-nickel.
