Germany’s DIN and DKE offer guidance for companies preparing for EU battery passport

The German Institute for Standardization (DIN) and the German Commission for Electrical, Electronic and Information Technologies (DKE) have developed a standard that defines the data attributes of battery passports, which will become mandatory.

The European Union’s Battery Regulation requires companies to create a passport for devices with more than 2 kWh of storage capacity and which are used in electric vehicles or industrial energy storage systems, from February 2027.

The passports will provide information about battery lifespan – from raw material origins, to performance and charging cycles, to end-of-life condition. Device carbon footprint and supply chain sustainability data must also be included.

DIN and the DKE have published the DIN DKE SPEC 99100 free standard to help companies meet battery passport requirements.

The document sets out requirements for the data attributes to be included in the digital passports. This legally required and voluntary information includes general battery and manufacturer information, material composition, performance and durability, and working conditions during battery raw material extraction.

International standard 

DIN DKE SPEC 99100 develops the “Content Guidance for the EU Battery Passport” published by the publicly funded Battery Pass Consortium and which was last revised in December 2023.

“The content guidance has laid the foundation for a practical explanation of the content requirements of the battery passport,” said Thomas Weber, president of the German Academy of Engineering Sciences. The new DIN and DKE guide offers clarity about which data need to be collected for the battery passport. “This represents another important step in putting digital product passports into practice and using their extraordinary potential for circular value creation,” added Weber.

Torsten Freund, battery passport project manager at German chemicals giant BASF, and chairman of the DIN DKE SPEC 99100 committee, said, “With DIN DKE SPEC 99100, we are now making the guidelines from the battery pass project easily accessible to all interested parties in preparation for the introduction of the battery pass in the European Union and at the same time creating a basis for further international standardization on this topic.”

DIN and DKE initiated the standard on behalf of the Battery Pass Consortium – an association of 11 international organizations from industry, technology, and science led by UK-based Systemiq. The Battery Pass Consortium has published an updated version of its “Data attribute longlist” – an overview of data attributes which can be filtered – on its website.

Germany’s Federal Ministry for Economic Affairs and Climate Protection is supporting development of the digital battery pass.
