Ensuring the precision and repeatability of component assembly in the
production of electric vehicle (EV) battery modules requires fast and
accurate measuring methods. The durability of EV battery packs depends
on the quality of welded connections, therefore exact positioning of the
module components is critical for ensuring safety in exploitation.
Laser welding is a non-contact process capable of welding dissimilar
materials with high precision, for that reason it has become the
preferred joining method in battery production. In high volume
manufacturing, one of the main production challenges is reducing the
time required for assessment of dimensional and geometrical accuracy
prior to joining. This paper reviews the challenges of EV battery design
and manufacturing and discusses commercially available scanner-based
measurement systems suitable for fabrication of battery pack components.
Versatility of novel metrological systems creates new opportunities for
increasing the production speed, quality and safety of EV battery
modules
