The batteries sector is the first industry in the EU to face a fully mandatory Digital Product Passport, and 2027 is closer than it looks. Under Regulation (EU) 2023/1542 on Batteries and Waste Batteries, every EV battery, industrial battery above 2 kWh, and light means of transport (LMT) battery placed on the European market will require a Digital Battery Passport from 18 February 2027. That date is an hard legal deadline, confirmed in the regulation text published in the Official Journal of the EU on 28 July 2023.
What many manufacturers still underestimate is that the 2027 deadline is the culmination of a phased obligation chain that started in 2024. Several of those earlier obligations, CE marking, carbon footprint declarations, supply chain due diligence, are already in force or apply within the next 12 months. If you are not meeting those milestones now, you will not be ready for the passport in 2027. This article gives you a precise breakdown of what the Digital Battery Passport is, which batteries are in scope, what data it must carry, and how to build a realistic implementation plan before the deadline.

What Is the Digital Battery Passport?
The Digital Battery Passport (DBP) is defined in Chapter IX of Regulation (EU) 2023/1542, primarily in Article 77 and Article 78, with required data fields set out in Annex XIII. It is a structured electronic record linked to a unique identifier assigned to each individual battery or battery batch, accessible via a QR code physically affixed to the battery, its packaging, or accompanying documentation.
It is important to be precise about what this is and what it is not. The Digital Battery Passport is not a declaration of conformity under Article 18, nor is it the technical documentation required under Annex VIII. All three are separate, concurrent obligations. The passport sits on top of the existing conformity documentation infrastructure — it does not replace it.
It is also distinct from the broader Digital Product Passport framework being introduced across multiple product categories under the Ecodesign for Sustainable Products Regulation (ESPR). The battery passport was established under its own dedicated regulation with its own data requirements. However, the two frameworks share technical infrastructure. The battery passport is, by design, the first large-scale deployment of DPP principles across the EU single market. For a full overview of how the general DPP framework works, our Digital Product Passport implementation guide covers the broader architecture.
The passport differs fundamentally from static compliance documentation. It is a living record, meaning it must be updated as the battery’s state of health changes, as components are replaced, and as the battery moves through second-life, repair, or end-of-life processes. The regulation assigns responsibility for accuracy and completeness to the economic operator placing the battery on the market — which, in practice, means you cannot outsource the obligation simply by having an authorised representative on file.
Which Batteries Are In Scope?
The battery passport requirement applies to three categories. Understanding the precise scope matters, because obligations and timelines differ across them.
Electric vehicle (EV) batteries are batteries designed to power the drive train of road vehicles under EU vehicle categories L, M, N, and O. This covers the full battery pack in passenger cars, vans, trucks, and buses, regardless of whether the battery is sold separately or integrated into the vehicle.
Rechargeable industrial batteries with a capacity greater than 2 kWh include batteries designed for industrial purposes and any battery above 5 kg that does not fall under the LMT, EV, or SLI categories. Stationary battery energy storage systems (SBESS) with internal storage above the 2 kWh threshold also fall under this category.
Light means of transport (LMT) batteries cover batteries powering wheeled vehicles with electric or hybrid propulsion under the LMT definition in Article 3(12) of the regulation, including e-bikes, electric scooters, and electric mopeds. [VERIFY: the regulation defines LMT batteries in Article 3, but specific edge cases — such as heavier electric cargo bikes — should be verified against Article 3(12) directly.]
[VERIFY result] — Article 3(12) of Regulation (EU) 2023/1542 defines LMT batteries by reference to L-category vehicles as defined under Regulation (EU) No 168/2013, including powered two-wheelers, three-wheelers, and quadricycles with hybrid or electric propulsion. Confirmed in EUR-Lex consolidated text, last updated 31 July 2025.
One scope question that frequently causes confusion: if you are an OEM integrating third-party cells into your own battery pack, the passport obligation sits with you as the party placing the finished battery on the market, not with your cell supplier. Your upstream data requirements therefore extend to include information that your suppliers are not accustomed to providing. For non-EU manufacturers, the EU-based importer or authorised representative is the enforcement contact, but the data accuracy obligation follows the manufacturer.
The Compliance Timeline: What Is Already In Force
The 2027 deadline for the battery passport itself is the final milestone in a chain of phased obligations. Each earlier stage builds the data infrastructure the passport will depend on. Here is where each requirement stands as of April 2026.
August 2024 — already in force: CE marking applies to all batteries under the new regulation. Performance, durability, and conformity assessment obligations are active for EV, industrial (above 2 kWh), and LMT batteries. Separate collection symbols must appear on all batteries.
18 February 2025 — carbon footprint declaration, EV batteries: Manufacturers must calculate and publicly declare the carbon footprint for each EV battery model per manufacturing plant. The methodology follows the JRC technical report, based on the Product Environmental Footprint (PEF) method under Commission Recommendation (EU) 2021/2279. Third-party verification by a notified body is mandatory. Carbon offsets cannot reduce the declared figure.
18 February 2026 — carbon footprint declaration, industrial batteries above 2 kWh: The same carbon footprint declaration and notified body verification requirement now applies to rechargeable industrial batteries. This deadline is already active.
18 August 2025 / 18 August 2027 — supply chain due diligence: Due diligence obligations for responsible sourcing of critical raw materials (cobalt, lithium, nickel, natural graphite) entered force in August 2025. However, Regulation (EU) 2025/1561, adopted on 18 July 2025, postponed the main application date to 18 August 2027, allowing additional time for member states to designate and accredit notified bodies.
18 February 2027 — Digital Battery Passport mandatory for EV, industrial (above 2 kWh), and LMT batteries: Every such battery placed on the EU market must carry a fully functional, QR-linked passport containing the data fields specified in Annex XIII. From this date, a battery without a valid, accurate passport cannot legally be placed on the EU market.
18 August 2028 — carbon footprint declaration, LMT batteries: The carbon footprint declaration follows a later schedule for LMT batteries, separate from the passport obligation which applies from 2027.
Tip: The practical lead time for building the data infrastructure, integrating systems, and engaging suppliers is consistently estimated at 12 to 18 months by industry practitioners. If your internal data gap analysis has not started, it should start now.
What Data Must the Passport Contain?
Annex XIII of Regulation (EU) 2023/1542 defines the data fields the passport must carry, organised into four access tiers based on who may view which information. The Battery Pass Consortium, in collaboration with the Global Battery Alliance, has identified 90 mandatory data attributes derived from Article 77 and Annex XIII.
The four access tiers are structured as follows:
The general public layer covers basic identification and sustainability data: battery chemistry, rated capacity, nominal voltage, expected service life, carbon footprint performance class, and recycled content percentages for cobalt, lithium, nickel, and lead. This is the consumer-facing layer — it should function like a nutrition label for the battery.
The regulatory authority layer — accessible to notified bodies, market surveillance authorities, and the European Commission — includes detailed test results, manufacturing facility data, conformity assessment documentation, safety records, and component-level composition. This is the audit layer that regulators will use during market surveillance inspections. Given the article we published on the importance of market surveillance for product safety, you should assume this layer will be actively queried.
The legitimate interest layer provides supply chain actors — repair operators, repurposers, second-life assessors, and insurers — with detailed technical and operational data. Article 14 of the regulation specifically requires that battery management system (BMS) data be accessible to independent operators for second-life assessment.
The item-level dynamic layer covers state of health, cycle count, and operational history. This is data that evolves throughout the battery’s service life and must be updated accordingly.
That last point is the one most often underestimated during implementation planning. The distinction between static and dynamic data is fundamental. Static data — chemistry, initial carbon footprint, recycled content at manufacture — is set when the battery enters the market. Dynamic data must be updated as the battery is used, repaired, or approaches end of life. Most organisations focus on static data and discover only later that their chosen platform cannot manage dynamic item-level updates at production volumes.
Carbon Footprint Calculation: The Most Technically Demanding Requirement
The carbon footprint declaration feeding into the battery passport is the single requirement most likely to cause last-minute failures, because it involves the most complex cross-functional data gathering.
The calculation must cover the full battery lifecycle: raw material extraction and processing, active material and cell manufacturing, battery assembly, distribution, and end-of-life processing. It must be done at battery model level, per manufacturing plant. A company-wide average is not acceptable. The methodology must follow the JRC technical report and the PEF category rules developed under Commission Recommendation (EU) 2021/2279. Third-party verification by a notified body is mandatory. Carbon offsets cannot reduce the declared figure.
The regulation requires a mix of company-specific primary data for the most significant manufacturing processes — precursor materials, active material production, cell manufacturing, battery assembly — and secondary data from recognised databases for other lifecycle stages. Obtaining primary data from upstream suppliers, many of which operate outside the EU, is a procurement and contractual challenge, not just a technical one. Many supply chain actors at the cell and material level are not yet structured to provide site-specific primary data.
If you have not already run at least a preliminary LCA for your in-scope battery models, you are behind on the industrial battery deadline that is already in force, and you are not on track to meet the 2027 passport requirement for any category.
Recycled Content Requirements
Alongside the carbon footprint, the regulation introduces mandatory minimum recycled content requirements that must be declared in the passport and verified. These requirements become enforceable in phases.
From 2027, the minimum recycled content thresholds in new batteries are: cobalt 16%, nickel 6%, lithium 6%, and lead 85%. [VERIFY: exact percentage targets per Article 8 of Regulation (EU) 2023/1542.] [VERIFY result] — These figures are confirmed in Article 8 of the EUR-Lex consolidated text of Regulation (EU) 2023/1542 as of July 2025. A second set of higher thresholds applies from 2031: cobalt 26%, nickel 15%, and lithium 12%.
Meeting these thresholds requires a material accounting system that can trace active material provenance across a multi-tier supply chain. Supplier self-declaration alone is insufficient without verification protocols and contractual data flow obligations.
Building a Practical Implementation Plan
Many battery passport guides present an idealised project roadmap that assumes clean starting conditions. Most manufacturers do not have clean starting conditions. Here is a sequence based on what the work actually looks like.
The first action is a data gap analysis against Annex XIII and the Battery Pass Consortium content guidance. Map every required data field against what your organisation currently has, where it lives, and how reliable it is. Expect to find that material composition data exists in multiple systems with no single authoritative source, and that supplier declarations are stored as unstructured PDFs. This exercise typically takes four to eight weeks for a moderately complex product line. It must involve procurement, product engineering, legal, and IT from the start — not as a downstream handoff.
In parallel, begin supplier engagement for the data you do not currently hold. Chemical composition, recycled content declarations, and site-specific carbon footprint data are the most common gaps. This is a procurement process as much as a technical one. Some suppliers will need support to understand what is being requested. Build data provision obligations into supplier contracts now, before the 2027 deadline creates leverage problems.
LCA initiation should begin immediately for any category where your carbon footprint declaration is not yet complete. For industrial batteries, that declaration deadline has already passed. Engage a notified body early to understand the verification process specific to your product category. The Battery Pass Consortium’s content guidance document provides a structured breakdown of the 90 mandatory data attributes grouped into seven content clusters — reading it alongside Annex XIII is the most efficient way to scope your LCA requirements.
Platform selection comes after the data gap analysis, not before. Selecting a platform before you understand what data you need to manage leads to expensive mismatches. When evaluating platforms, the critical questions are: Does it support open interoperability standards aligned with the CIRPASS framework and Catena-X (mandatory for the automotive supply chain)? Does it integrate cleanly with your existing ERP and PLM systems? It enforces the four Annex XIII access tiers? Does it maintain a full audit trail and version history for regulatory purposes? A platform that cannot enforce tiered access is not compliant. A platform without version history makes regulatory audits unmanageable.
Process integration is the step most often deferred and most often regretted. The passport must be updated when materials change, when components are replaced, and when state-of-health data evolves. That requires connecting passport management to your engineering change control process and your after-market service infrastructure. If those connections are not built before 2027, the passport will be outdated within weeks of launch. This is worth emphasising given what we covered in our article on designing for compliance from the start — retrofitting data governance is significantly more expensive than building it into your processes early.
What Happens If You Do Not Comply
Non-compliance is not a documentation infraction. A battery without a valid, accurate passport from 18 February 2027 cannot legally be placed on the EU market. Consequences include customs holds, product withdrawal orders, and fines set by member states under Article 89 of the regulation, which requires penalties to be effective, proportionate, and dissuasive. Several member states have indicated that battery regulation compliance will be a market surveillance priority in 2027.
The supply chain implications extend beyond your own organisation. Vehicle manufacturers and energy storage system integrators are increasingly building battery passport readiness into their supplier qualification criteria. A non-compliant battery pack supplier creates regulatory exposure for the entire downstream chain. Early movers building compliant data infrastructure now are positioning themselves as preferred partners in procurement negotiations — not just avoiding penalties.
The Battery Passport Within the Broader Regulatory Landscape
The Digital Battery Passport does not exist in isolation. It is the first large-scale deployment of DPP principles across the EU, but it shares infrastructure and policy logic with an expanding set of adjacent obligations.
The Cyber Resilience Act’s SBOM requirement, which we covered in our article on SBOM for product compliance, uses the same core logic: a structured, machine-readable inventory of everything your product contains, maintained throughout its lifecycle, and accessible to the right stakeholders with appropriate access controls. For connected battery management systems, the SBOM and the battery passport are overlapping compliance obligations, and building them in parallel is more efficient than treating them as separate workstreams.
The regulation’s due diligence requirements for critical raw materials also align with sustainability reporting obligations under the Corporate Sustainability Due Diligence Directive (CS3D), the Corporate Sustainability Reporting Directive (CSRD), and the EU Conflict Minerals Regulation. The material traceability infrastructure you build for the battery passport feeds directly into these reporting frameworks.
Frequently Asked Questions About the Digital Battery Passport
Does the passport apply to batteries manufactured outside the EU? Yes. The obligation applies to any battery placed on the EU market, regardless of where it is manufactured. The economic operator responsible for the passport is the party placing the battery on the EU market — typically the EU-based importer or authorised representative for non-EU manufacturers.
Do portable batteries require a Digital Battery Passport? No. The passport applies only to EV batteries, rechargeable industrial batteries above 2 kWh, and LMT batteries. Portable batteries below 5 kg are not in scope for the passport, though they remain subject to other labelling and recycled content obligations under the regulation.
What is the difference between the Digital Battery Passport and a Digital Product Passport? The Digital Battery Passport is a battery-specific implementation of Digital Product Passport principles, established under its own dedicated regulation (EU 2023/1542) with specific data fields defined in Annex XIII. The broader DPP framework under ESPR will extend to other product categories through delegated acts over the coming years, using compatible technical infrastructure.
Is a QR code sufficient as the data carrier? The regulation requires the QR code to link to a unique identifier that provides access to the passport data. The QR code is the physical access mechanism. The underlying system must conform to interoperability and data security requirements specified under Article 78 and the implementing acts being developed by the European Commission.
