The concept of the digital twin as an image of a physical counterpart is currently under development and is delivering promising initial results. At the same time, the objectives and definition of digital twins differ significantly depending on the area of application and use case. The descriptions and concepts of digital twins for a specific application can therefore not simply be transferred to new fields of application. Meanwhile, battery cell production is a key technology in the energy and mobility transition, which is still characterised by high costs and reject rates and will benefit enormously from the use of digital twins.

In order to create a basis for the development of digital twins in battery cell production, this white paper presents a standardised definition of the digital twin in battery cell production based on existing work. To this end, three types of digital twin were identified: the building twin, the plant twin and the product twin. Each of these forms must be considered in detail so that components of the respective forms can be identified, exemplary use cases can be shown and concrete goals and challenges can be defined. Based on the concepts described in this white paper, the digital twin will be used to track, optimise and control products and processes in battery cell production in the future. In the long term, this can significantly improve energy, raw material and cost efficiency in this important area of the future.
