What is battery laser welding?

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.

Can laser welding be used in EV battery production?

Of these, laser and ultrasonic welding processes dominate in EV battery manufacture – with laser welding the preferred solution for mass production – and continue to be improved and refined. “We see a lot of laser welding and ultrasonic wedge bonding for the larger packs,” says Boyle at Amada Weld Tech.

What types of welding do EV batteries need?

“In these situations, cooperative development and reliable relationships are of high value.” While there many kinds of welding, in EV battery applications the most common are resistance welding and laser welding, along with ultrasonic welding and wire bonding, and benefit from standardisation for mass production.

Why is welding important for EV battery systems?

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.

Can a laser weld a battery?

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.

What types of battery cells can be laser welded?

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.
