BatteryPass-Ready: Data Attributes and Test Infrastructure for the EU Digital Battery Passport
At an exchange event organized by eWAVE partner SYRION, Dr. Johannes Simböck (Project Lead) and Sven Geppert (Scientific Officer) from acatech, National Academy of Science and Engineering in Germany, presented key results of the former BatteryPass project and the current status of the BatteryPass-Ready project on 10 February 2026. There was an extremely high level of interest in this event from the eWAVE partner consortium, which also contributed actively to the relevant Q&A and discussion session.
The EU Digital Battery Passport
The Digital Battery Passport (DBP) is set to become mandatory from 18 February 2027 for all electric vehicle (EV) batteries, light means of transport (LMT) batteries, and industrial batteries above 2 kWh (including shipping batteries) that are brought to market in Europe. As a pioneering digital product passport within the EU, the DBP aims to drive digitalization across B2B, B2C, and public-sector interactions, support the transition to a circular economy and promote transparent, sustainable value chains.
The BatteryPass-Ready project
BatteryPass-Ready (https://thebatterypass.eu/) is a Germany-based, pre-competitive project that evolved from the earlier Battery Pass consortium. It will run from April 2025 to March 2027. Led by Fraunhofer IPK, together with acatech, GEFEG, and TU Berlin, and backed by over 100 supporting partners, including SYRION, the project is funded by the German Federal Ministry for Economic Affairs and Energy. Its core mission is to deliver a publicly available test environment that will enable industry and SMEs to verify their battery passport systems before the regulatory deadline.
Test Development Methodology and Data attributes for the EU Digital Battery Passport
The first part of the presentation by S. Simböck introduced the test development methodology, which follows a five-step process: requirements analysis, user stories, test scenarios, failure scenarios, and test procedures. This process covers the entire lifecycle of a battery passport, from initial market placement through repair, and recycling.
The second part of the presentation by S. Geppert focused on the data side, with the team using DIN DKE Spec 99100 as a starting point for defining battery passport data attributes. These attributes cover categories such as carbon footprint, materials and composition, circularity, performance and durability, and supply chain due diligence. A key ongoing challenge is keeping pace with the rapidly evolving regulatory and standardization landscape, including delegated acts under the Battery Regulation (BattReg) and the DPP standardization work of CEN/CENELEC JTC-24, which is expected to deliver technical standards by summer 2026. The latest list of data attributes, based on the current standardization work, was just recently published in March 2026 (https://thebatterypass.eu/news/now-published-data-attribute-longlist-v1-3/).
Looking further ahead, the first prototype for the test environment has been developed and initial tests implemented. According to J. Simböck and S. Geppert, the test environment is planned to be publicly available by June 2026, with iterative optimization based on early user feedback to follow.
eWAVE – Towards a Digital Battery Passport for Maritime Applications
Unlike the automotive industry, there has been relatively little focus on developing a passport for maritime applications for some time, but this has been changing significantly over the past few months.
eWAVE aims to develop the foundations of a ‘Digital Battery Passport’ (DBP) specifically for martime batteries, building on initiatives such as the German ‘BatteryPass’ and ‘BatteryPass-Ready’ projects whilst focusing on the specific requirements of the maritime sector. This is being carried out in close consultation and collaboration with the ‘Battery Passports for Maritime Batteries’ working group of the Maritime Battery Forum (MBF), which was established in early 2026, with SYRION acting as the central interface between the MBF and eWAVE.
