The guidance provides a framework and recommendations for implementation, while the demonstrator validates some of the technological approaches described in the guide. Both were developed within the "Battery Pass" project, and both are intended to provide recommendations and promote a transparent and sustainable battery value chain. The guidance supports all stakeholders in the battery ecosystem in minimizing implementation costs. The results contribute to the standardization of the battery passport to meet EU requirements. A holistic system architecture is presented to ensure interoperability and security. A secure information exchange along the value chain will be demonstrated. 

"The Battery Passport is the pilot for a series of product passports that will become reality in the next three to ten years. The technical guidance takes this into account and provides a comprehensive information package for companies concerned, particularly in the battery sector, but also for other industries. Based on an interoperability framework, it considers system components, appropriate technologies and relevant standards to meet the requirements of the EU Battery Regulation. The overarching design goals for the DPP system are technology openness and cost efficiency by enabling interoperability through coexisting standards," says Prof. Thomas Knothe, Head of the Business Process and Factory Management department at Fraunhofer IPK.
