Digital Battery Passport: Open Standard Provides Investment and Implementation Security
IDTA, Catena-X and Battery Pass Project develop interoperable AAS-based model for timely and scalable implementation until 2027.
In a joint initiative, Industrial Digital Twin Association (IDTA), Catena-X Automotive Network e.V. and members of the Battery Pass Project have developed a technological approach and a common semantic basis for the Digital Battery Passport. The solution addresses all data requirements defined in the EU Battery Regulation and transfers them into a scalable, standards-based data model. At the core of the specification is the implementation of the Digital Battery Passport based on the Asset Administration Shell (AAS) and the accompanying Semantic Aspect Meta Models (SAMM) with the aim of implementing the European Union’s regulatory requirements regarding sustainability, transparency and traceability of batteries. For this purpose, the working group developed seven Submodels for the AAS, SAMM for semantic description and a guideline that provides a framework for the specified Submodels and the corresponding design decisions. This approach offers economic actors an open, standardised and ready-to-use basis for implementing the regulatory requirements, thus creating investment and implementation security.
The EU Battery Regulation (EU) 2023/1542 will come into force on 18 February 2027 and requires every battery affected to be equipped with a QR code linked to the Digital Battery Pass in order to be allowed on the EU market. The regulation applies to industrial batteries with a capacity of more than 2 kWh (e.g. for stationary energy storage systems), batteries for electric vehicles and batteries for light means of transport (LMT), such as e-bikes or e-scooters.
The developed AAS Submodels structure the required information in a context-related manner, e.g. material composition, circular economy or product condition. This was done in close accordance with DIN DKE Spec 99100 and by using existing Submodels as well as the semantics of Catena-X, ECLASS and IEC CDD. Based on the standardised AAS API, the data for the Digital Battery Pass can be provided via a clearly defined interface.
In addition, Catena-X intends to incorporate the jointly developed AAS Submodels into a future release of the Catena-X data ecosystem (CX-Neptune, September this year) as a standardised use case for the Digital Battery Passport.
“With the AAS as the technological foundation for extracting data for the Digital Battery Passport, we ensure efficient implementation in existing systems and data spaces. This approach offers a robust and interoperable solution and combines regulatory compliance with strategic data sovereignty. It creates the groundwork for new data-based business models, increases transparency and resilience in the supply chain, and at the same time minimises implementation risks through the consistent use of open standards,” says Dr. Birgit Boss, member of the IDTA Board of Directors.
