EU Battery Passport data is now a board-level deadline, not a future project. From 18 February 2027, Article 77(1) of Regulation (EU) 2023/1542 requires every electric vehicle battery, light means of transport (LMT) battery, and industrial battery above 2 kWh placed on the EU market or put into service to carry an electronic battery passport. A battery without one cannot be placed on the market.
The hard part is not producing a document on deadline day. It is assembling, verifying, and structuring the underlying EU Battery Passport data across a multi-tier supply chain. That work is a data infrastructure build, and it runs for many months. For most manufacturers, the window to start it in a controlled way is closing.
If battery products sit in your EU portfolio, a short compliance review now will tell you how much of your passport data already exists and how much must still be collected.
Key Takeaways
⏳ The EU battery passport becomes mandatory on 18 February 2027 under Article 77(1) of Regulation (EU) 2023/1542. Covered batteries without a passport cannot be placed on the EU market.
🏭 Scope covers every EV battery, LMT battery, and industrial battery above 2 kWh. Portable batteries and industrial batteries at or below 2 kWh are not covered by Article 77(1) on that basis alone.
📊 The passport is a per-unit digital record carrying Annex XIII data: identity, materials, carbon footprint, performance, due diligence, and end-of-life, served at three access tiers.
🔗 Most of that data lives across several supplier tiers, which is why passport readiness is a supply chain data problem, not a last-minute formatting task.
⚠️ The due diligence postponement under Regulation (EU) 2025/1561 (now 18 August 2027) did not move the passport deadline. 18 February 2027 stands.
🤖 Automating multi-tier supplier data collection, certificate validation, and BOM-level material mapping is the practical route to passport-ready battery data at scale.
What the Battery Passport Is, and What Article 77 Requires
The battery passport is an electronic record tied to an individual battery and reached through a QR code linked to a unique identifier. It is the first mandatory Digital Product Passport under EU law, established by Article 77 of the EU Batteries Regulation (Regulation (EU) 2023/1542).
Article 77(1) is specific. From 18 February 2027, each in-scope battery placed on the market or put into service "shall have" a battery passport. There is no transition grace period written into the deadline, and because this is a Regulation rather than a Directive, the date applies directly across all member states with no national transposition. The legal text sits on EUR-Lex.
Which batteries are in scope
The Article 77 battery passport requirement does not apply to every battery. Scope is defined by category and, for industrial batteries, by capacity.
Battery category | Battery passport required under Article 77? |
|---|---|
Electric vehicle (EV) batteries | ✓ Yes |
Light means of transport (LMT) batteries (e-bikes, e-scooters, e-mopeds) | ✓ Yes |
Industrial batteries above 2 kWh | ✓ Yes |
Industrial batteries at or below 2 kWh | ✗ Not on this basis alone |
Portable batteries | ✗ Not on this basis alone |
SLI batteries (starting, lighting, ignition) | ✗ Not on this basis alone |
If you manufacture, import, or distribute EV, LMT, or large industrial batteries into the EU, the EV battery passport and its industrial equivalent are in your scope from day one of the deadline.
Why 18 February 2027 Is a Data Problem, Not a Document Problem
Compliance teams sometimes treat a passport like a certificate: assemble the facts near the deadline and publish. The battery passport breaks that assumption. The data it requires is not data most companies already hold in one place.
Carbon footprint figures depend on calculated lifecycle data from cell and material suppliers. Recycled content shares for cobalt, lithium, nickel, and lead must be sourced and verified upstream. Supply-chain due diligence data has to be traced across multiple tiers. Per-unit performance and state-of-health data depends on serialisation and a working unique identifier scheme.
None of that is produced by a document template. It is produced by a multi-tier supply chain transparency program that collects, validates, and structures supplier data over time. That is why the practical lead time for passport-ready battery data is measured in quarters, and why the energy and mobility sectors covered in Certivo's energy storage and battery compliance analysis are already treating this as a system build.
What Goes Into the Passport: Annex XIII Data and the Three Access Tiers
Annex XIII of Regulation (EU) 2023/1542 is the data specification. It divides the record between information about the battery model and information specific to the individual battery, including data generated in use.
Across those two levels, Annex XIII covers:
Battery identity and the unique identifier
Materials and chemical composition, including hazardous substances
Carbon footprint (already required for EV batteries on a phased basis)
Performance and durability, including per-unit state of health and cycle data
Recycled content shares
Supply-chain due diligence information
End-of-life data, including dismantling and recycling information
The three access tiers
Article 77(2) does not make the passport one flat public page. It sets three access tiers, and the right data must reach the right audience.
Access tier | Who can read it | Example data |
|---|---|---|
Public | Anyone scanning the QR code | General model information and headline sustainability data (Annex XIII point 1) |
Legitimate interest | Repairers, recyclers, second-life operators | Detailed composition, dismantling and safety information, certain performance data (Annex XIII points 2 and 4) |
Authority | Notified bodies, market surveillance authorities, the Commission | Authority-only data (Annex XIII point 3) |
Article 77(9) tasked the European Commission with adopting an implementing act, due by 18 August 2026, defining who qualifies as a person with a legitimate interest and how much restricted data they may access, download, and reuse. Based on currently available regulatory guidance, those detailed legitimate-interest rules should be confirmed against the latest Commission publications. The public and authority tiers, however, are already defined by Annex XIII and can be built and tested now.

The 12-18 Month Build: Why Passport-Ready Data Takes This Long
The "12-18 month" figure is not set by the Regulation. It is an operational planning estimate that reflects how long it realistically takes to stand up passport-ready battery data infrastructure across a complex supply chain. The dependencies, not the deadline, drive the timeline.
The workstreams that run in parallel
Data model mapped to Annex XIII. Define every field, its source, its owner, and its access tier before collection starts.
Identifier and QR scheme. Assign a unique identifier per battery and link it to the record, with the identifier uploaded to the EU Digital Product Passport registry (added through the ESPR, Regulation (EU) 2024/1781).
Multi-tier supplier data collection. Carbon footprint, recycled content, and composition data must come from cell makers, material suppliers, and their suppliers in turn.
Due diligence traceability. Chain-of-custody data over cobalt, natural graphite, lithium, and nickel, the same minerals covered by broader conflict minerals and ethical sourcing work.
Certificate validation. Incoming declarations, test reports, and mill data must be checked for authenticity and consistency, not just filed.
Access-tier architecture. Public, legitimate-interest, and authority data must be separated from the start, not retrofitted later.
Each workstream depends on suppliers who respond at their own pace. That dependency is why automated supplier data collection and structured supplier portals matter more here than any single reporting template, a pattern Certivo describes in its work on multi-tier compliance across global suppliers.
A candid read for teams starting in Q4 2026: a full build is no longer available in the time remaining. The realistic posture is to prioritise. Build the public and authority tiers against Annex XIII, lock the data model and identifiers, and sequence the harder multi-tier due-diligence data behind them. Starting now is what keeps 18 February 2027 a managed deadline rather than a market-access failure.
How Article 77 Interacts With Battery Due Diligence
A common planning error is to assume the 2025 postponement moved everything. It did not.
Regulation (EU) 2025/1561 amended Article 48 of the Batteries Regulation and postponed battery due diligence obligations from 18 August 2025 to 18 August 2027, with the Commission's guidelines deadline reset to 26 July 2026. That change is confirmed on EUR-Lex and summarised in the Commission's batteries regulation overview.
The amendment did not touch Article 77. The battery passport deadline remains 18 February 2027. The two dates serve different purposes, and they should be tracked separately.
Date | Obligation | Legal basis |
|---|---|---|
18 February 2027 | Battery passport mandatory (EV, LMT, industrial above 2 kWh) | Art. 77(1), Reg (EU) 2023/1542 |
18 August 2027 | Battery due diligence obligations apply (postponed) | Art. 48, as amended by Reg (EU) 2025/1561 |
The practical link between them is the data. Due diligence traceability over battery raw materials is also passport content under Annex XIII. Teams that build regulatory intelligence and horizon scanning into a single system can feed one data backbone into both obligations instead of running two disconnected projects.
Who Owns This Inside the Organisation
The battery passport is not solely a compliance task. It crosses functions, and unclear ownership is the most common reason build programs stall.
Compliance and regulatory own interpretation of Article 77 and Annex XIII, access-tier rules, and evidence.
Product data and engineering own the data model, identifiers, QR implementation, and in-use performance data.
Procurement and supply chain own supplier data collection and multi-tier traceability.
CFO and leadership own the resourcing decision and the market-access risk. A missing passport is a market-access block, not a fine to budget for.
Naming a single accountable owner across these functions, early, is what separates programs that finish from programs that discover gaps in January 2027.
A Practical Readiness Sequence for Q4 2026 Onward
1. Confirm scope. Identify every EV, LMT, and above-2 kWh industrial battery model you place on the EU market. Confirm which legal entity is the responsible economic operator for each.
2. Map Annex XIII to your data. For every field, record where the data lives today, who owns it, and which access tier it belongs to. Flag the fields you do not yet hold.
3. Lock identifiers and QR. Decide the unique identifier scheme and QR implementation, and confirm the registry upload path under Article 77(10).
4. Launch supplier data collection now. Request carbon footprint, recycled content, composition, and due diligence data through structured supplier data workflows rather than email and spreadsheets.
5. Validate as data arrives. Check certificates and declarations at intake, not during an audit, and map them to the battery at BOM level.
6. Build public and authority tiers first. These are defined by Annex XIII and can be implemented before the legitimate-interest access rules are finalised.
7. Keep records audit-ready. Maintain time-stamped, version-tracked evidence so you can show point-in-time compliance, in line with staying audit-ready across frameworks.

How Certivo Supports Battery Passport Data Readiness
The battery passport exposes a structural gap in most compliance operations: the data is spread across suppliers, documents, and systems that were never designed to assemble into a per-unit record. Certivo exists to close that gap.
Certivo acts as the centralised compliance data backbone for product and supply-chain data. It automates supplier data collection through structured portals, so carbon footprint, recycled content, and composition data arrive in a usable form rather than as scattered attachments. Its supplier and contractor management workflows reduce the manual follow-up that slows every multi-tier program.
CORA, Certivo's embedded AI intelligence, supports the document-heavy parts of the build. CORA-powered regulatory intelligence tracks changes across the Digital Product Passport landscape and related acts, while AI document parsing and certificate validation help teams check incoming declarations at scale and map materials at BOM level. The result is structured, audit-ready data that can feed passport data models and DPP tooling, explained further on the Certivo features page and in the broader DPP 2027 analysis.
Certivo does not generate the passport in place of your systems, and no platform removes the obligation to hold accurate data. What it does is shorten the hardest part of the build: getting trustworthy supplier data into one place, verified, mapped, and ready to use.
Conclusion
The 18 February 2027 battery passport deadline is fixed, and it was not moved by the 2025 due diligence postponement. For EV, LMT, and large industrial batteries, a passport is a condition of placing the product on the EU market. The work that decides whether a manufacturer meets it is not formatting a record near the deadline. It is building the EU Battery Passport data, field by field, supplier by supplier, across a multi-tier chain, and that build takes far longer than the months now remaining allow for a relaxed start.
Manufacturers who treat Q4 2026 as the moment to lock scope, launch supplier data collection, and build the public and authority tiers will enter 2027 managing a deadline. Those who wait will spend early 2027 discovering what they cannot yet prove.
To build passport-ready battery data before 2027, request a compliance review and map your current Annex XIII data gaps across products and suppliers.
