A battery pack has a huge number of cells, which is why stacking and connecting them is a fully automated process. Robots bring all of the different cells and spacers between them together to create battery modules. Each complete battery pack consists of a few battery modules. ZEISS coordinate measuring machines are the ideal solution to make sure every single cell is in the right position in the tray. Non-contact measuring technology like ZEISS laser triangulation is safe and reliable due to the high voltage inside the battery packs. ZEISS X-ray technology is a fast, non-destructive solution to check the connection weld seams between the single cells – ensuring full functionality and capacity.
