Digital Twins in Battery Cell Production

A digital twin enables the accessibility of data, information, models, and simulations for a physical object. Therefore, digital twins become increasingly relevant for different areas of production. In particular, the production of battery cells with its high complexity could benefit from digital representations such as digital twins. Still, there is no coherent definition for digital twins in the battery cell production yet. In this paper we introduce the first concept of digital twins in battery cell production. For this we combine existing ideas for the digital twin with the characteristics of the battery cell production. The concept consists of digital twins for buildings, products, and machines or assets, which we validate based on different use cases. By this, we demonstrate the benefits that arise from the implementation of digital twins in battery cell production - from increased productivity, faster ramp-ups, to increased sustainability.
