Climate change promotes the emergence of new concepts for mobility in order to reduce CO2 emissions and minimize the consumption of fossil fuels. As a result, more and more automotive companies are changing their portfolios from internal combustion engines to electric motors due to legal requirements of the EU. This also means that the energy source of automobiles is changing from diesel or gasoline to electrical energy. Battery cells are needed to store this energy in the car. The battery cells can in turn be used to build battery modules and battery packs. The demand for batteries is increasing worldwide. This also creates new requirements for quality and efficiency. In addition, the degree of digitalization in manufacturing industries, such as car manufacturers, continues to increase. The quality of the batteries can be guaranteed with different methods. One method is predictive quality, which can be used to predict quality in advance. But which process steps in battery cell production benefit from this quality method?

Excerpt from the Book
3 Battery cell production with predictive quality
Due to the high cost and construction share of batteries in electric vehicles, the requirements for the production of battery cells are particularly high. The production process of battery systems and battery cells is complex and cost-intensive and therefore offers optimization potential through quality and testing processes such as predictive quality.
3.1 Battery system requirements
The requirements for the individual battery cell can only be defined after the requirements for a battery system are understood. For this purpose, the further processes after the production of a cell are examined.
