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 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.
Which welding methods are used in the production of battery applications?
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.
Can a battery be welded?
There are only so many ways to join materials together, and for battery applications – particularly where high currents and voltages and tough operating environments are encountered – welding beats alternatives such as soldering, conductive adhesives and mechanical fasteners.
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 do battery cells need to be welded?
Battery cells are most often put into modules or packs when produced for electrically driven vehicles. The variable of greatest influence when welding battery packs is the contact resistance between the cell and the connection tab. It is crucial to minimize this variable as much as possible to prevent energy loss in the form of heat generation.
