6 FAQs about [Energy storage ring welding]
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.
How does resistance welding work?
Resistance welding passes an electric current between a pair of electrodes and though the materials to be joined, relying on the heat generated by ohmic resistance to melt and fuse them. It is a proven and relatively cheap process, but has limitations in the applications and geometries to which it is suited.
How do you Weld a battery pack?
“We see a lot of laser welding and ultrasonic wedge bonding for the larger packs,” says Boyle at Amada Weld Tech. “If the packs or the overall volume are smaller, then resistance welding is often used. Micro-TIG comes up for specialised battery packs with low-volume production.
Why are battery contacts so difficult to weld?
At the highest level, reliability and process speed are the main engineering challenges in welding battery contacts and structures, he notes. Carr concurs, and cites cost and customers’ desire to use the latest materials, such as grades of aluminium that are super-light but hard to weld and seal shut.
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.
Should you use resistance welding or micro-Tig?
“If the packs or the overall volume are smaller, then resistance welding is often used. Micro-TIG comes up for specialised battery packs with low-volume production. “Recent developments in galvo scanning, beam steering and process monitoring allow for faster speeds and improved process error detection, respectively,” he adds.
