EU Battery Passport: Everything You Must Know

The Most Urgent DPP Deadline in Europe

Of all the Digital Product Passport requirements rolling out under EU regulation, the Battery Passport has the earliest hard deadline and the most detailed technical requirements. From 18 February 2027, every industrial battery above 2 kWh and every electric vehicle battery placed on the EU market must carry a digital passport accessible via QR code.

Regulation (EU) 2023/1542 is binding law. Non-compliant batteries cannot be placed on the EU market after February 2027.

This is not a future proposal. The regulation entered into force in August 2023 and the countdown is running. With less than 12 months remaining for most manufacturers, the implementation window is narrower than it appears — particularly for companies that need to align multi-tier supply chains or implement new data infrastructure.

This guide covers everything you need to know: which batteries are in scope, what data the passport must contain, the full compliance timeline, and the practical steps to prepare your organisation now.

Which Batteries Are Affected?

The Battery Regulation distinguishes between four categories. Three face the February 2027 deadline; portable batteries are deferred to a future delegated act.

Practical implication: if your company manufactures, imports, or distributes any of the first three categories into the EU single market — including via third-party importers — the obligation applies to you. Non-EU manufacturers must designate an EU authorised representative who assumes compliance responsibility.

What Data Must the Battery Passport Contain?

The Battery Passport is the most data-intensive DPP mandate issued to date. The regulation specifies four primary data domains, each with granular sub-requirements.

1. Battery Identification

• Unique identifier per battery (QR code compliant with GS1 Digital Link or equivalent standard)

• Battery model, chemistry type, and manufacturer details

• Date and country of manufacture

• Intended use and compatible vehicle/equipment types

• EU Declaration of Conformity reference

2. Chemical Composition

• Active cathode and anode materials (e.g. NMC, LFP, NCA)

• Critical raw materials: cobalt, lithium, nickel, natural graphite, manganese

• Percentage of recycled content per hazardous substance

• Hazardous substance declarations above threshold concentrations

• From 2027: minimum recycled content thresholds for cobalt (16%), lithium (6%), nickel (6%)

3. Carbon Footprint

• Site-specific, batch-level carbon footprint declaration in kg CO₂e per kWh

• Calculated from raw material extraction through cell manufacturing (cradle to gate)

• Methodology: JRC technical specification (ISO 14067 aligned)

• Carbon footprint must be declared per lifecycle stage

• Important: carbon offsets cannot be used to reduce the reported figure

• From February 2029: carbon footprint performance class thresholds will apply (maximum limits)

4. Performance and Durability

• Original rated capacity (Ah) and energy (kWh)

• Electrochemical performance parameters at time of manufacture

• Expected battery lifetime (cycles and calendar life)

• Capacity thresholds for end-of-life determination

• State of Health (SoH) data — updated throughout the battery's operational life

• State of Charge (SoC) and power capability metrics

5. Supply Chain Due Diligence

• Origin of critical raw materials: cobalt, lithium, nickel, natural graphite

• Supplier identities for Tier 1 (and where material, Tier 2/3)

• Certification of responsible sourcing for conflict-affected minerals

• From August 2027: formal due diligence obligations under Article 72

6. End-of-Life and Recyclability

• Dismantling information for repairers and recyclers

• Recycled content percentages post-consumer waste

• Collection and recycling instructions

• Recovery efficiency data per material

Full Compliance Timeline

Who Bears the Compliance Obligation?

The Battery Regulation follows the same economic operator logic as the broader ESPR framework. The compliance obligation falls on:

• Manufacturers established in the EU — directly responsible for creating and maintaining the battery passport

• Importers — must verify the manufacturer has fulfilled their obligations before placing batteries on the EU market

• Authorised representatives — non-EU manufacturers must designate an EU-based representative who assumes legal responsibility

• Distributors — responsible for ensuring batteries they supply carry the required QR code and accessible passport

The practical implication for non-EU manufacturers (US, Chinese, Korean, Japanese battery makers) is significant: the EU importer or authorised representative becomes the point of legal accountability. Read our full guide for non-EU brands navigating EU DPP obligations.

How the Battery Passport Must Be Accessed

The regulation is specific about access and data architecture:

• The passport must be accessible via a QR code physically attached to the battery or its packaging

• The QR code must link to a live, updateable data record — a static PDF is not compliant

• Data must be accessible to three distinct audiences with different permission levels: consumers (limited public data), market surveillance authorities (full access), and professional repairers/recyclers (technical data)

• The underlying data must use open standards to ensure interoperability — GS1 Digital Link and verifiable credentials are the emerging reference implementations

• State of Health data must be updated dynamically throughout the battery's operational life — this requires a connected infrastructure, not a point-in-time record

• The underlying data registry must retain records for the battery's entire commercial lifetime plus 10 years, operated by an EU-recognised economic operator or notified body

This last point is the most underestimated technical challenge. The Battery Passport is not a document — it is a live data service. Companies that approach it as a labelling exercise will find themselves non-compliant. For a deeper look at the interoperability challenge, see our article on UNTP and DPP data readiness.

5 Actions to Take Before End of 2026

With the February 2027 deadline approaching, the implementation window is tighter than most organisations realise. Data collection and supply chain alignment typically take 12–18 months. Here is a sequenced action plan:

1. Map your battery portfolio — identify every product by category (EV, LMT, industrial) and capacity threshold. Products below 2 kWh may still be in scope for future acts; document them now.

2. Begin carbon footprint calculation — commission a site-specific, batch-level LCA aligned to JRC methodology. This is the longest-lead item: expect 6–9 months for a rigorous calculation across a multi-site supply chain.

3. Align Tier 2 and Tier 3 suppliers — origin traceability for cobalt, lithium and nickel requires data from mining and refining operations, not just cell manufacturers. Start supplier engagement now.

4. Select a DPP platform — evaluate providers capable of generating unique QR codes per battery, storing and serving live data at scale, managing multi-stakeholder access permissions, and integrating with your PLM/ERP systems. Browse verified Battery Passport solution providers on DPP Pro.

5. Plan your EU authorised representative — if you are a non-EU manufacturer, identify and contract your EU representative before mid-2026 to allow sufficient onboarding and legal review time.

6. Pilot before scaling — run your chosen DPP platform and data pipeline on a single battery model first, resolve data gaps and supplier onboarding issues there, then roll out across your full range.

The Business Case Beyond Compliance

Compliance is the floor, not the ceiling. Companies building robust Battery Passport infrastructure are positioning themselves for competitive advantages that extend well beyond regulatory adherence:

• Improved residual value — verified, granular performance data enables more accurate State of Health assessments, commanding higher prices in the growing second-life battery market

• Recycling efficiency — precise chemical composition data enables targeted material recovery. Industry estimates suggest up to 90% cobalt and nickel recovery rates when composition data is accurately declared, versus 60–70% with current methods

• €1.2 billion/year in additional EU recycling revenue is estimated from Battery Passport adoption across the industry (EU Commission impact assessment)

• Battery-as-a-service models — reliable, real-time lifecycle data is the foundation for leasing and performance-based business models that are gaining traction with fleet operators

• Supply chain resilience — traceability to raw material origin gives early visibility on supply disruption risks for critical minerals

Frequently Asked Questions

What is the EU Battery Passport?

The EU Battery Passport is a digital record mandated by Regulation (EU) 2023/1542 for all electric vehicle and industrial batteries above 2 kWh placed on the EU market. It provides comprehensive, dynamically updated data on battery identification, chemical composition, carbon footprint, and performance throughout its lifecycle, accessible via a QR code attached to the battery.

Which batteries are affected by the February 2027 deadline?

Three categories face the 18 February 2027 deadline: electric vehicle (EV) batteries, Light Means of Transport (LMT) batteries such as e-bikes and e-scooters, and industrial rechargeable batteries with a capacity above 2 kWh. Portable batteries (consumer electronics, power banks) are not in scope for 2027 but will be addressed in a future delegated act.

Does the Battery Passport apply to non-EU manufacturers?

Yes. Any battery placed on the EU market must comply, regardless of where it is manufactured. Non-EU manufacturers must designate an EU-based authorised representative who assumes legal compliance responsibility. US, Chinese, Korean, and Japanese battery makers exporting to Europe are all in scope.

What data must be included in the Battery Passport?

The passport must include: battery identification data (unique ID, model, manufacturer, date/country of manufacture), chemical composition (active materials, critical raw materials, recycled content percentages), a site-specific batch-level carbon footprint calculated using JRC methodology, performance and durability data (capacity, State of Health, expected lifetime), supply chain due diligence records for critical minerals, and end-of-life and recyclability information.

Is a static PDF or document compliant as a Battery Passport?

No. The regulation requires a live, updateable digital record accessible via QR code. State of Health data must be updated throughout the battery's operational life. A static document issued at the time of manufacture does not meet the dynamic data requirements. Companies need a digital infrastructure capable of serving real-time data to multiple stakeholder groups with differentiated access permissions.

What are the carbon footprint requirements for the Battery Passport?

Manufacturers must declare a site-specific, batch-level carbon footprint in kg CO₂e per kWh, covering raw material extraction through cell manufacturing (cradle to gate). The methodology must align with the JRC technical specification (ISO 14067 compatible). Carbon offsets cannot be used to reduce the declared figure. From February 2029, maximum carbon footprint thresholds (performance classes) will be enforced, meaning batteries exceeding the limit cannot be placed on the EU market.

What are the penalties for non-compliance?

Penalties are set at the member state level and vary by country. However, the commercial consequence is uniform: batteries without a valid passport cannot legally be placed on the EU market after 18 February 2027. Market surveillance authorities have powers to require withdrawal of non-compliant products. The EU is also developing a centralised battery passport registry to enable cross-border enforcement.
