Selecting the appropriate battery pack welding technology to weld battery tabs involves many considerations, including materials to be joined, joint geometry, weld access, cycle time and budget, as well as manufacturing flow and production requirements. Fiber laser welding
Battery Module: Manufacturing, Assembly and Test Process Flow. In the Previous article, we saw the first three parts of the Battery Pack Manufacturing process: Electrode Manufacturing, Cell Assembly, Cell Finishing. Article Link In this article, we will look at the Module Production part.
Whether 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.
In order to engineer a battery pack it is important to understand the fundamental building blocks, including the battery cell manufacturing process. This will allow you to understand some of the limitations of the cells and differences between batches of cells. Or at least understand where these may arise.
The mechanical connection of the battery pack is made e.g. by mountings in the base module and corresponding screw connections (M10-M14). Mountings are used to mount the same accumulators in different vehicle derivatives. High battery weight requires modified front/rear module design.
Resistance welding Resistance welding is the most cost-effective method to weld battery tabs, using both DC inverter closed loop and capacitor discharge power supplies.
