In areas such as electric vehicles, e-bikes and industrial energy storage systems, batteries play a critical role in achieving climate neutrality. However, it is not always easy to compare their sustainability and performance. To improve this situation, the digital battery passport, which will be mandatory across the EU from February 2027, aims to document data on batteries throughout their entire lifecycle.
In this context, a new standard, DIN DKE SPEC 99100, “Requirements for the Data Attributes of the Battery Passport”, offers companies practical guidance in implementing this passport. Published by the German Institute for Standardization (DIN) and the German Commission for Electrical, Electronic and Information Technology (DKE), this standard defines the data attributes that must be included in the battery passport.
Based on the requirements of the EU Battery Directive and optional additions, DIN DKE SPEC 99100 specifies the data attributes that must be included in a digital battery passport. These attributes include general information about the battery and the manufacturer, battery materials and composition, performance and durability, working conditions in raw material extraction and the carbon footprint of the battery. This standard provides valuable guidance to economic operators in determining the data required for the future battery passport.
DIN DKE SPEC 99100 is based on the “Content Guide for the EU Battery Passport” of the publicly funded Battery Passport Consortium, updated in December 2023. This guide supports the implementation of the battery passport in line with the requirements of the EU Battery Regulation. The newly published standard provides companies with clarity on the specific data attributes that need to be collected for the battery passport, providing an important step towards the use of digital product passports.
DIN DKE SPEC 99100 makes the guidance results of the Battery Passport Consortium easily accessible to all those preparing for the implementation of the battery passport in the European Union. At the same time, it lays the foundation for the establishment of international standards on this topic. The Federal Ministry for Economic Affairs and Climate Protection (BMWK) is supporting the development of the digital battery passport. The “Content Guide for the EU Battery Passport” was developed by the Battery Passport Consortium, a collaboration of eleven international organizations led by Systemiq.
