The search was then performed using Uppsala University’s Library database and Google scholar which cover a wide range of articles and sources. Three methods for welding batteries were given in the template, being laser beam-, ultrasonic-, and resistance spot welding.
How long does it take to weld a battery pack?
For a battery pack consisting of 117 Cells (9 x 13), this means there are 234 sites to weld and total process time of 514.8 seconds. Since laser welding is a non-contact process, the only motion is making a weld pattern and the motion moving the beam from cell to cell. The weld cycle time is a combination of shots and small motion on a cell.
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.
