Key facts
- EU Regulation 2023/1542 Article 77 sets 18 February 2027 for covered electric vehicle, light means of transport and industrial batteries over 2 kWh.
- The passport is linked to the finished battery through a QR code and unique identifier; detailed data have public and restricted access levels.
- The obligation generally applies to covered batteries placed on the EU market or put into service after the start date; existing batteries are not all retroactively covered.
- The Commission says carbon footprint, recycled content and due-diligence information will not all be required at the February 2027 launch.
- The economic operator placing the finished battery on the EU market is responsible, although some practical tasks may be delegated in writing.
From 18 February 2027, an electronic battery passport becomes mandatory in the European Union for electric-vehicle batteries, batteries used in light means of transport and industrial batteries with a capacity above 2 kWh when placed on the EU market or put into service. Under Regulation (EU) 2023/1542, Article 77, the passport is a digital record associated with an individual finished battery and accessible through a QR code. It aims to make battery identity, performance and circularity-related information more transparent.
However, not every battery-passport field must contain data on the first day. The European Commission’s 2026 implementation guidance explains that carbon footprint, recycled-content and due-diligence information follow their own legal application dates. This guide sets out what is confirmed for 2027, what is still being implemented and how the requirements differ for EV owners, manufacturers and importers.
What exactly is the EU battery passport?
The battery passport is an electronic record connected to a particular battery through a unique identifier and QR code. The European Commission’s battery digital product passport overview says the record may include battery identification, technical characteristics, relevant performance and durability information, and information supporting repair, reuse and recycling.
The system is built under the EU Batteries Regulation and connected to the broader Digital Product Passport (DPP) technical framework. It is not a paper certificate that a car driver must purchase separately, nor is it a guarantee that every battery uses exclusively recycled materials.
For physical end-of-life processing rather than product-documentation rules, see our separate EV battery recycling guide.
When does the EU battery passport become mandatory?
The legal starting date under Article 77 is 18 February 2027 for the covered battery categories placed on the EU market or put into service. The Commission states that the DPP Registry began operating on 20 July 2026, ahead of the passport’s application deadline, while technical standards and access-rights rules have been developed in stages.
| Milestone | What it means |
|---|---|
| 2023 | Regulation (EU) 2023/1542 establishes the legal battery passport framework. |
| 20 July 2026 | The Commission says the DPP Registry became operational. |
| 19 October 2026 | Commission data-point guidance was updated, clarifying data applicability and access groups. |
| 18 February 2027 | Passport obligation begins for relevant newly placed-on-market or put-into-service batteries. |
| Later dates | Some carbon-footprint, recycled-content and supply-chain due-diligence disclosures apply under separate provisions. |

Which battery categories need a passport?
| Battery type | Passport from February 2027? | Important qualification |
|---|---|---|
| Electric vehicle traction battery | Yes | Finished battery placed on the EU market or put into service from the relevant date |
| Light means of transport (LMT) battery | Yes | Includes relevant e-bikes, e-scooters and e-mopeds under the regulatory definition |
| Industrial battery above 2 kWh | Yes | Includes qualifying stationary storage products, including some home energy storage systems |
| Individual battery cells/modules awaiting assembly | Generally not separately | Normally assessed as components, not yet the finished battery |
| Ordinary portable battery | Not under the Article 77 categories listed here | Other labeling and QR requirements may still apply |
The European Commission’s August 2026 guidance announcement identifies EV, LMT and industrial batteries above 2 kWh, and the Commission FAQ explains how to identify a finished battery when several packs share a battery management system. The relevant unit is not automatically every removable module.
Does every EV already on the road need a passport in 2027?
No blanket retroactive passport for every existing car is described by Article 77. The primary obligation concerns covered batteries placed on the market or put into service from 18 February 2027. A battery in a car that was already placed on the EU market before that date does not automatically need a new passport solely because the calendar reaches February 2027.
There is a meaningful qualification: the Commission says a previously marketed battery remanufactured after the requirements become applicable can require a new passport, with applicable exceptions for fields whose legal requirements do not apply. This is different from ordinary repair. Buyers should not treat the absence of a passport on a 2024 used EV as proof that the vehicle is non-compliant.
What information will buyers be able to scan?
The passport is accessed through a QR code and unique identifier associated with the finished battery. The legal framework separates public information from information intended for authorities and data accessible only to parties with a legitimate interest. The Commission explains that the public part follows the relevant provisions of Annex XIII, while restricted access remains subject to detailed implementing rules.
Depending on the battery and applicable provisions, records may refer to identity, chemistry, technical properties, durability and appropriate end-of-life information. A publicly scannable code does not mean anyone can download every sensitive manufacturing detail, individual usage record or proprietary repair instruction.
Does scanning reveal the battery’s exact state of health?
Not necessarily to every member of the public. Some use-related and battery-management data can be dynamic and subject to restricted access. The Commission’s access and dynamic-data FAQs distinguish public fields from information available to authorized parties. Do not promise that scanning a QR code will show a reliable, real-time state-of-health (SoH) percentage for every used EV.
Even an available health measurement needs interpretation of the manufacturer’s methodology, battery buffer and test conditions. For practical used-car checks, consult our used EV battery health guide.
Will carbon footprint and recycled content be mandatory in February 2027?
Not automatically. The Commission’s October 2026 guidance and current FAQ explicitly explain that carbon-footprint, recycled-content and due-diligence information are not yet required in the battery passport at its February 2027 launch. Those fields depend on separate regulatory obligations and technical implementation dates. Some information can therefore be lawfully absent at the start.
This is a critical difference between a passport becoming mandatory and every sustainability field being completed. Claims that every EV battery will display a verified carbon-footprint number on 18 February 2027 overstate the current requirement.
To understand what a properly bounded carbon-footprint calculation measures, read our IEA-based electric-car lifecycle emissions guide. A battery’s future product carbon-footprint declaration is not identical to the lifetime emissions of a whole car driven in a particular country.
Who is responsible for creating a battery passport?
The economic operator that places the finished battery on the EU market or puts it into service is responsible. The Commission says an EU battery producer may be responsible when it supplies a complete functional battery to a vehicle assembler, while a company that completes an unfinished battery with essential components may become the responsible operator. For an imported product containing a finished battery, the importer can have this obligation under the relevant circumstances.
The responsible operator may authorize another company in writing to create or maintain the passport data, but delegation does not transfer the underlying legal responsibility. Suppliers of individual cells do not automatically need separate Article 77 passports for every component shipped to an EU battery assembler.
Does the EU Registry store every battery data record?
No. The Commission describes a decentralized passport structure. Detailed battery records are hosted and maintained by the responsible economic operator or an authorized service provider, while the DPP Registry primarily manages the required registration information and metadata. That is different from imagining one public EU website hosting every full private battery history.
Businesses preparing for the deadline should read the published Registry implementation guidance, understand operator verification and check which application programming interface (API), bulk upload or manual procedures their system supports.
What happens when an EV battery is repaired, reused or recycled?
| Event | Passport consequence described by Commission FAQ |
|---|---|
| Simple battery repair | A new passport is not required merely because of the repair. |
| Repurposing or remanufacturing | A new passport can be required, linked to the earlier passport as prescribed. |
| Battery becomes waste | Responsibility can pass to the relevant producer-responsibility or waste-management operator. |
| Battery is recycled | The battery passport ceases to exist under the Commission’s explanation. |
These distinctions are set out in the Commission’s section on repair, remanufacturing and end of life. The passport supports traceability and reuse decisions, but the mere existence of the record does not mean every pack can be economically repaired or repurposed.
What should manufacturers and importers prepare in 2026?
- Map finished battery products and categories: identify which batteries fall into EV, LMT or industrial categories and confirm the relevant capacity thresholds.
- Assign legal responsibility: document which operator places the finished battery on the EU market, and any written delegation.
- Build accurate identifiers: make sure each covered battery can be linked to its unique identifier and appropriate QR code.
- Classify information by access rights: distinguish public data, authority-accessible data and restricted information for legitimate-interest users.
- Identify fields due at launch versus later: do not treat every future sustainability field as mandatory in February 2027.
- Prepare data updates and lineage: have processes for repair, repurposing, remanufacturing and end-of-life status changes.
- Test the Registry process: verify identity, registration and interoperability procedures against the Commission’s current implementation documents.
- Re-check technical requirements before launch: restricted-access implementing rules and guidance may change.
What should a used electric-car buyer do in 2027?
A passport may eventually help buyers distinguish battery models and find applicable public technical information. But it is not a replacement for an actual battery-health test, vehicle history, warranty check or recall lookup. For an older EV, the initial 2027 market-placement date matters. For a newer vehicle, check whether the specific battery and market are covered and which information is public at the time.
For the broader legal and practical distinction between recalls and battery service, see our EV VIN and recall guide, which describes U.S.-market checks separately from EU passport requirements.
The bottom line
The EU battery passport starts on 18 February 2027 for specific newly marketed or commissioned battery categories, including EV traction batteries. It links a finished battery to an electronic record through a QR code, with public and restricted data managed under separate access rules. Not all older batteries must be retroactively registered, and carbon-footprint and recycled-content data are subject to later application conditions. The most useful preparation is to follow the current Commission guidance, identify the responsible economic operator and distinguish what is due in February 2027 from future disclosure obligations.

Sık Sorulan Sorular
When does the EU electric vehicle battery passport start?
Article 77 of the EU Batteries Regulation requires a battery passport from 18 February 2027 for covered new EV traction batteries, LMT batteries and industrial batteries above 2 kWh placed on the EU market or put into service.
Do all older electric cars need a battery passport in 2027?
Not automatically. The core obligation concerns batteries placed on the market or put into service from the start date; later remanufacturing or repurposing can create additional requirements.
Does the QR code show an EV battery's exact state of health?
Not necessarily to the general public. The rules distinguish public and restricted data, and access to certain usage and state-of-health information depends on the applicable provisions.
Will carbon footprint and recycled content be mandatory in February 2027?
The European Commission says these fields are not universally required at the launch; carbon-footprint, recycled-content and due-diligence information follows separate legal application dates.
Who must create the EU battery passport?
The economic operator that places the finished battery on the EU market or puts it into service is responsible, even if another company is formally authorized to carry out some of the practical data work.
Does replacing a faulty cell or repairing a battery require a new passport?
A simple repair does not automatically require a new passport. Remanufacturing or repurposing can require a linked new passport under the Commission's guidance.
