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.
Which weld is best for EV battery packs?
Use minimal weld energy to prevent excessive heating of the internal cell separator . High quality welds are of uniform width and have no gaps. Thin welds are more suited for EV battery packs. Thicker ones can penetrate the casings. Proper welds address the following welding challenges & :
How are battery cells welded?
Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.
What material should a battery pack be made of?
In general, Boyle says, manufacturers want light, highly conductive, increasingly efficient battery packs, and they often choose materials such as copper and aluminium, both of which are difficult to weld, making joining current collectors to cell cans a challenge.
Which welding methods can be used for battery assembly?
Other joining methods such as micro-tungsten-inert-gas welding (micro-TIG), micro-clinching, soldering, and magnetic-pulse welding exist and have been proposed for battery assembly applications, but they are not well established, and therefore their feasibility is still being evaluated, or they are not widely used in the industry.
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.
