The Battery Passport Is Getting Closer — State of Play, Summer 2026
Starting in February 2027, the Digital Battery Passport (DPP) becomes mandatory for industrial batteries and traction batteries with a capacity of 2 kWh or more. The legal basis is the Battery Regulation (EU) 2023/1542, which entered into force in August 2023. What sounds abstract is becoming a concrete compliance task for manufacturers, importers, and recyclers: data must be machine-readable, standards-compliant, and permanently accessible — via a unique identifier for which GS1 Digital Link is the preferred format.
Summer 2026 brings a surge of activity: test environments are going live, standards bodies are publicly explaining their requirements, and open-source tools are emerging to support quality assurance. At the same time, the question of how dynamic operational data — most notably State of Health (SoH) and State of Charge (SoC) — should be handled technically and legally remains open.
Test Environments and Webinars: Industry Gets Ready
BatteryPass-Ready: Public Test Environment Since June 2026
On June 24, 2026, the BatteryPass-Ready consortium coordinated by Fraunhofer IPK launched a public test environment for the Digital Battery Passport. Manufacturers can upload real datasets and verify whether their systems meet the requirements of the Battery Regulation — before going live in production. The environment maps all prescribed data attributes, from cell chemistry and CO₂ footprint to recycling rates.
For companies that have not yet built out a DPP infrastructure, this is a low-barrier entry point: no production environment, no regulatory consequences, but real data validation against the standard requirements.
European Commission: Second Webinar on Interoperability and Readiness
On July 7, 2026, the European Commission held its second webinar on the Digital Battery Passport. The focus was on data requirements, interoperability between different national registries, and the state of industry readiness. A key discussion point was how data from different links in the value chain — cell manufacturers, battery packers, OEMs — can be consolidated and kept up to date.
CEN/CENELEC: Standards Explained, Questions Answered
On June 25, 2026, CEN and CENELEC held a public webinar explaining the relevant European standards and answering industry questions. The event was explicitly aimed at companies that want to understand which technical standards underpin the DPP framework — and how those standards need to be implemented in practice.
Static and Dynamic Data: The Underestimated Core Challenge
The Battery Regulation implicitly distinguishes between two categories of data that require fundamentally different technical treatment.
Static data is fixed at the time of placing on the market: cell chemistry, manufacturer, rated capacity, production CO₂ footprint, material composition. These values do not change — they can be captured once, signed, and stored in the passport.
Dynamic data, by contrast, changes continuously. State of Health (SoH) and State of Charge (SoC) shift with every charge and discharge cycle. The regulation requires that these parameters be accessible in the passport — which means a permanent, write-capable connection to battery management systems (BMS) or cloud backends.
This is not a peripheral issue: a battery that has been in service for ten years will have a fundamentally different SoH at end of life than it did at the point of sale. For recycling or second-life applications, that value is critical. If you design your DPP infrastructure only for static data, you will not be able to meet the regulation's requirements over the medium term.
Open-Source Tools: DP-AWB for Quality Assurance
In July 2026, researchers published the Digital Passport Assessment Workbench (DP-AWB) as an open-source tool. It computes deterministic assessment results directly from SHACL model specifications, enabling automated validation of DPP data structures.
SHACL (Shapes Constraint Language) is a W3C standard for describing and validating RDF graphs. In the DPP context, this means: if you validate your datasets against a SHACL specification, you can automatically determine whether all required fields are present, correctly typed, and internally consistent — before the passport is published in a registry.
DP-AWB is primarily aimed at developers and data owners who want to systematically test DPP implementations. It is not a substitute for regulatory conformity assessments, but it is a useful tool during the development phase.
The Bigger Picture: Textiles, Steel, and the ESPR Architecture
The Battery Passport is the first, but not the last, use case. The Ecodesign for Sustainable Products Regulation (ESPR) creates the framework for additional product categories.
Textiles: Information Alone Is Not Enough
The Ellen MacArthur Foundation published a white paper on July 9, 2026 identifying a central weakness of the information-based approach: transparency about material properties alone does not change design decisions. The Foundation calls for the upcoming ESPR delegated act for textiles to mandate binding performance requirements — such as minimum durability and recyclability — rather than limiting itself to data obligations.
At the same time, SGS analyzed a JRC preparatory study that proposes specific data points for the textile DPP: in addition to material composition and care instructions, the study includes facility identifiers (GLN) and product identifiers (GTIN/SGTIN) — a direct alignment with GS1 standards already being discussed for the Battery Passport.
Steel: Orgalim Warns Against Over-Regulation
For iron and steel products, Orgalim issued a position paper on July 3, 2026 warning against extending the DPP scope to finished products. The association calls for a strict limitation to intermediate products, arguing that downstream manufacturers would otherwise face disproportionate compliance burdens. Orgalim had previously made clear that registries must support high-volume, automated registration processes — a requirement that is difficult to meet for granular finished goods.
MaterialsCommons: Making Materials Data Interoperable
The MaterialsCommons project, funded by the European Commission, is working to make materials and process data machine-readable and interoperable. This is a prerequisite for DPPs in materials-intensive industries: if you don't know which alloy is in which component, you cannot issue a meaningful passport.
What Manufacturers Should Do Right Now
The time remaining until February 2027 is short. Three action areas are particularly urgent:
1. Clarify your data architecture: Which data is fixed at the time of placing on the market, and which changes during operation? Dynamic data requires an API-capable connection to BMS or telemetry systems — a static document will not suffice.
2. Define your identifier strategy: GS1 Digital Link is the preferred format for linking the physical product to its digital record. If you don't yet have a GTIN structure in place, act now — assignment and integration take time.
3. Use the test environments: The BatteryPass-Ready environment and DP-AWB are both publicly accessible. Testing early reduces the risk of discovering data quality problems right before the deadline.
The regulatory architecture is complex, but the direction is clear: the DPP is coming, it will expand to more product categories, and it will require technical infrastructure that goes far beyond a simple data sheet.
