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.
Fusion welding, specifically using electron beams or lasers, is the best method for welding battery components. Both electron beam and laser welding offer high power densities, pinpoint accuracy, and are well-suited for automated welding processes and small, miniature weld applications.
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.
Depending on the project parameters, both laser welding and electron beam welding can be cost effective for battery arrays. However, battery array configurations are becoming more compact, and designs are continually evolving.
Welding 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.
Because the common material of the battery housing is steel and aluminum and other refractory metals, it will also face various problems. In this paper reviews, the challenges and the latest progress of laser welding between different materials of battery busbar and battery pole and between the same materials of battery housing are reviewed.
