Battery Passport: EU DPP for Batteries
Batteries are the first product group for which passport obligations are already fixed in sector-specific EU law. That makes the battery track fundamentally different from sectors still waiting for later ESPR delegated acts. For covered categories, the key challenge is now operational: manufacturers, importers and distributors need to connect compliance, engineering, sustainability and product-data systems before February 2027, rather than simply monitor future policy signals.
Battery passports are not a distant ESPR scenario. For covered categories, the core compliance date is already fixed: 18 February 2027.
Regulatory Timeline
EU Battery Regulation enters into force
Regulation (EU) 2023/1542 establishes the battery passport framework and the wider compliance architecture for batteries placed on the EU market.
Secondary rules on carbon-footprint methodology progress
The carbon-footprint regime moves from high-level legal obligation toward category-specific methodology and implementation work for EV, industrial and LMT batteries. This is the point where companies need cleaner plant, model and supply-chain data.
Carbon and technical documentation requirements become operational
Manufacturers need to align declarations, supporting technical documentation and source evidence with the categories they place on the market. The exact secondary rules are not identical across all covered battery types, so companies should avoid assuming one uniform compliance package.
Systems, identifiers and data governance need to mature
This is the practical preparation window for mapping battery identifiers, technical documentation, lifecycle metrics and supplier evidence into one passport-ready structure. The legal direction is already set, but the internal operating model often is not.
Industrial Accelerator Act proposed
The European Commission proposed the Industrial Accelerator Act, which includes Made-in-EU and low-carbon procurement preferences for batteries, steel, cement and aluminium. While not a DPP act itself, it reinforces traceability and origin certification expectations for battery value chains.
Horizontal DPP standards: drafts in progress (CEN/CENELEC)
CEN and CENELEC are developing eight harmonised technical standards covering the DPP data model, data carrier, registry and access-rights framework. With the battery passport deadline less than a year away, these standards confirm the IT infrastructure layer that passport systems must align with.
Battery passport obligations apply
Passport requirements apply to EV batteries, industrial batteries above 2 kWh and all LMT batteries (regardless of capacity).
Battery due diligence obligations apply (postponed by Reg. 2025/1561)
Regulation (EU) 2025/1561 postponed Article 48 supply-chain due diligence for cobalt, lithium, natural graphite and nickel from 18 August 2025 to 18 August 2027. Commission guidelines are due by 26 July 2026, aligned with CSDDD.
Passport operations move from launch to auditability
After go-live, the challenge becomes maintaining accurate passport records across design changes, batch changes, imported cells or modules, and downstream service events. For many companies, this is where governance becomes more difficult than initial publication.
Recycled content targets tighten
Mandatory recycled-content thresholds for cobalt, lead, lithium and nickel further increase the need for traceable and auditable battery data.
What must the battery passport contain?
66 attributes · 8 clusters
Tiered Data Access (Art. 77)
Battery passport data is not equally visible to all parties. Under Art. 77 of Regulation (EU) 2023/1542, the same data attribute may return different content depending on who requests it. The general public sees summary information, while market surveillance authorities can access full reports including commercially sensitive details.
| Attribute | Public | Authorities |
|---|---|---|
| Due diligence report | Summary statement and policy URL | Full audit report with supplier names, prices and sourcing details |
| Test reports | Conformity declaration reference | Complete test results with laboratory data |
| Negative events log | Not visible | Full incident log for authorities and legitimate-interest operators |
* "Interested parties" (Art. 77) covers persons with a legitimate interest, including independent repairers, remanufacturers, second-life operators and recyclers. Implementing acts specifying exact access rights are due by 18 August 2026.
** BMS = Battery Management System. Dynamic attributes are updated over the battery lifecycle via on-board telemetry (OTA) or at service events.
*** Each recycled-content percentage denotes the share of recycled feedstock within that specific material (e.g. "16% cobalt" means 16% of the cobalt used is post-consumer recycled cobalt). These are independent ratios per substance, not shares of total battery mass, so they do not sum to 100%.
**** Source labels (e.g. ERP, BMS, LCA) indicate which enterprise system typically holds each data cluster. They are architectural guidance for IT integration, not regulatory requirements.
Which Batteries Are Covered?
Under Regulation (EU) 2023/1542, the battery passport is relevant in particular for:
- EV batteries used in battery-electric and plug-in hybrid vehicles
- industrial batteries above 2 kWh used in storage, backup and industrial systems
- all LMT batteries for light means of transport such as e-bikes and e-scooters (regardless of capacity)
- manufacturers, importers and distributors responsible for placing covered batteries on the EU market under their own name or brand
- OEM, engineering, quality and compliance teams that must align one battery record across product, testing and regulatory systems
- companies already collecting carbon, recycled-content, sourcing or performance data, but still holding it in disconnected supplier files, spreadsheets or lab documentation
- battery pack assemblers, storage-system providers and mobility brands that rely on upstream cell or module data they do not fully control
Note: Traditional automotive starter batteries (SLI batteries) are exempt from the Art. 77 digital passport. They must still carry a QR code with basic information (declaration of conformity, collection info, capacity) per Art. 13(5) of the Regulation.
