EU Battery Passport 2027: Scope, Data Requirements and Compliance Checklist

From 18 February 2027, covered batteries placed on the EU market or put into service must have a digital battery passport. The obligation applies to electric vehicle (EV) batteries, light means of transport (LMT) batteries, and industrial batteries with a capacity greater than 2 kWh.

The passport is not just a QR code. The economic operator placing the finished battery on the market must maintain an accurate, interoperable, access-controlled record containing model information and, where applicable, data about the individual battery and its use.

On 21 August 2026, the European Commission announced an updated data-point guidance document. It maps 71 potential data points across the covered battery categories. The guidance is useful for implementation, but it is not legally binding and not every point applies to every battery.

At a Glance

Does Your Battery Need a Passport?

Use the battery category, not the product label or company size, to determine scope.

The requirement applies to covered batteries placed on the EU market or put into service from the deadline. It does not matter whether the battery was manufactured inside or outside the EU. Classification should be completed at model and SKU level before a data platform or QR workflow is selected.

Who Is Responsible?

Article 77 assigns responsibility to the economic operator placing the finished battery on the market. The Commission explicitly distinguishes that operator from suppliers of cells, modules or other components.

The exact responsible entity depends on the transaction and how the finished battery is placed on the market. Contracts should identify who owns each data field, but a contract cannot erase the legal responsibility of the regulated operator.

What the 2026 Guidance Adds

The legal requirements remain in the Battery Regulation. The Commission's August 2026 guidance makes them easier to implement by collecting 71 data points into one category-by-category matrix.

For each point, the matrix identifies its legal source and whether it is mandatory, optional, conditionally applicable, deferred or not required for EV, LMT and industrial batteries as of February 2027. This distinction matters: copying all 71 rows into a mandatory checklist would overstate the obligation, while using a generic model across all battery types could omit applicable data.

The official battery-passport implementation page should be treated as a living source. The Commission advises users to check for newer guidance versions as implementation progresses.

What Data Goes Into the Passport?

The passport combines model-level information with information specific to an individual battery. Access depends on the sensitivity and intended use of the data.

“Legitimate interest” is not a general public-access category. It is intended for activities such as repair, dismantling, remanufacturing, second-life use, recycling, residual-value assessment and certain energy-market uses. Commercially sensitive access must be limited to what is necessary.

Most companies will need data from several systems:

• Product lifecycle management and bills of materials
• Supplier declarations and material traceability records
• Manufacturing execution and quality systems
• Laboratory, conformity and performance-test reports
• Carbon-footprint and recycled-content calculations
• Battery management systems and in-use telemetry
• Warranty, repair, repurposing and waste-management records

For each applicable field, record the source system, accountable owner, evidence, validation rule, update event and access level. That field-level ownership map is more important than the choice of passport software.

QR Code, Identifier and Technical Requirements

The QR code links to a unique identifier attributed by the economic operator placing the battery on the market. Article 77 references the ISO/IEC 15459 series or an equivalent standard for the code and identifier.

The underlying passport must also be:

• Based on open standards and interoperable formats
• Transferable through an open, interoperable data-exchange network without vendor lock-in
• Machine-readable, structured and searchable
• Protected by authentication, integrity, security and privacy controls
• Available even if the responsible operator ceases trading in the EU
• Free to access for authorised users according to their access rights

If a service provider stores or processes passport data, it may not sell, reuse or process that data beyond what is necessary to provide the service. Vendor contracts should also cover continuity, export, access logging, incident handling and termination.

What Is Final and What Is Still Evolving?

The Registry stores unique identifiers and associated metadata; product data remains decentralised. The Commission says registration can be performed through a user interface or API, and the current testing phase is intended to support implementation before the first battery deadline. See the Commission's Registry launch announcement.

Battery Due Diligence Has a Different Deadline

Do not confuse the passport deadline with the Battery Regulation's supply-chain due-diligence deadline. The battery-passport obligation begins on 18 February 2027. The relevant battery due-diligence obligations were postponed to 18 August 2027, according to the Council of the EU.

This affects when responsible-sourcing information becomes applicable. It does not postpone the battery passport itself. The applicability matrix should therefore track the legal start date of each underlying data obligation instead of treating every field as mandatory on the first passport day.

Compliance Checklist

1. Classify every battery model

Identify EV, LMT and industrial batteries above 2 kWh that may be placed on the EU market from the deadline. Record nominal energy, intended use, responsible economic operator, importer arrangements and private-label products.

2. Build an applicability matrix

Map the Commission's 71 points to each battery category and model. Mark every field required, conditional, optional, deferred or not applicable, with its legal source and effective date.

3. Assign data ownership

For every applicable field, document the source system, accountable owner, evidence, validation rule, update frequency and access tier. Add contractual data-delivery requirements for suppliers.

4. Implement identifiers and registration

Define how compliant unique identifiers and QR codes will be created, applied and associated with the correct passport. Test Registry registration through the appropriate interface or API.

5. Implement access controls

Separate public, authority-only and legitimate-interest information. Document identity verification, access approval, revocation, logging and commercially sensitive data controls.

6. Build lifecycle update events

Define who updates state of health, operating history, incidents, repair and status changes. A repurposed, re-used or remanufactured battery requires a new passport linked to the original passport or passports.

7. Test a real product end to end

Run a pilot from production identifier through QR scan, Registry registration, public access, restricted access, data update and audit export. Test incorrect identifiers, unavailable systems, supplier-data changes and service-provider failure.

8. Monitor official changes

Assign an owner to monitor the Commission's battery-passport page, data-point matrix, Registry documentation, access-rights measures, harmonised standards and amendments to Annex XIII.

Frequently Asked Questions

When does the EU battery passport become mandatory?

From 18 February 2027, every electric vehicle battery, light means of transport battery, and industrial battery with a capacity greater than 2 kWh placed on the EU market or put into service must have a battery passport.

Which batteries need an EU battery passport?

The requirement covers electric vehicle batteries, batteries for light means of transport such as e-bikes and e-scooters, and industrial batteries above 2 kWh. Ordinary portable consumer batteries are not included solely because they are batteries.

Who is responsible for the battery passport?

The economic operator placing the finished battery on the EU market is responsible for creating and maintaining the passport. Depending on the supply chain, that may be an EU manufacturer, an importer, or an OEM placing a finished battery on the market. Component and cell suppliers provide data but are not responsible merely because they supplied a component.

Are all 71 data points mandatory for every battery?

No. The Commission guidance maps 71 potential data points and identifies whether each is mandatory, optional, conditionally applicable, or not required as of February 2027 for each battery category.

Is a QR code enough for compliance?

No. The QR code links the battery to a unique identifier and passport. The underlying data must be accurate, machine-readable, interoperable, searchable, protected by access controls, and kept available throughout the relevant lifecycle.

Does a repurposed or remanufactured battery keep its original passport?

No. A battery prepared for re-use or repurposing, or placed on the market after repurposing or remanufacturing, must receive a new battery passport linked to the original passport or passports.
