➀ The Fraunhofer IPA's Center for Digitalized Battery Cell Production (ZDB) has launched a flexible winding machine for cylindrical battery cells in partnership with acp systems AG. It serves as a platform for testing new cell formats, components, and tab designs. It enables the development of large-format cells for future battery technologies. The winding machine is unique globally and integrated into an automated and digitalized infrastructure for battery cell production. ➁ The machine is not only a production platform for Jelly Rolls but also a research platform for developing and testing innovative cell systems and formats. ➂ The entire production process is digitalized and networked to minimize waste and improve quality. Data collected by sensors are processed in real-time in the cloud, allowing for traceability technologies that can attribute data to individual battery cells. This enables data analysis, AI training, and the development of monitoring and predictive services.
