Customer ServiceWhether to power our latest portable electronic device, power tool, or hybrid/electric vehicle, the removable battery pack is essential to our everyday lives. Tab-to-terminal connection is one of the key battery pack welding applications.
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.
The fitness and purpose of the weld needs to be thoroughly tested, however. In the case of an aluminum battery tab to a nickel plated cold rolled steel battery can the mechanical pull strength is quite strong along the direction of anticipated vibrations.
Laser welding is significantly faster showing the allure of the laser for battery module welding. Cycle time can be reduced even further with the use of a galvo scanning system, where some motion is handled by quick motions in the galvo head, and then indexed after all cells within the welding field are addressed.
This therefore provides a highly controlled method of developing localised welding temperatures that are suitable for joining materials up to 0.5 mm thick onto conductive battery cans. The TIG battery welding process has been tested and proven with a number of battery pack designs using nickel, aluminium and copper flat.
To avoid the shunting of current, the tab needs to be carefully designed with slots and tabs to concentrate the energy and guide the weld energy to specific spots. When laser welding, the joint geometry of the battery tab weld is a lap weld, which means the laser must penetrate fully through the top tab and at least slightly into the can wall.
