The world market leader for battery production, Contemporary Amperex Technoloy Co. Ltd (CATL), has had a production site in Arnstadt, Thuringia, for around a year now. Together with the nearby Battery Innovation and Technology Center (BITC), a site of the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS), the company is developing models for calculating the service life of batteries. The activities are based on Germany’s first-ever battery service life development model at the site, just as the collaboration between CATL and BITC/IKTS is the first of its kind in Germany. The previous collaboration between CATL and IKTS called “BattLife” is now being expanded as part of the new “BattForce” project: The test center operated by the partners will be expanded and operated with new technology. The benefits are legion. After all, a lot depends on increasing the service life of the storage systems – a decisive criterion for optimizing production and maintenance processes and the use of resources. (hw)
