EU Battery Regulation and DPP Requirements

Introduction to the EU Battery Regulation

The EU Battery Regulation (Regulation 2023/1542) is one of the most ambitious pieces of sustainability legislation ever adopted by the European Union. Entering into force on 17 August 2023, it replaces the previous Battery Directive and introduces comprehensive requirements covering the entire battery lifecycle, from raw material sourcing through manufacturing and use to collection, recycling, and second-life applications.

Perhaps most significantly for the purposes of this article, the Battery Regulation is the first EU legislation to mandate Digital Product Passports for a specific product category. The battery passport requirements, which apply to electric vehicle batteries, light means of transport batteries, and industrial batteries with a capacity above 2 kWh, serve as a pioneering test case for the broader DPP framework that will be rolled out under the ESPR across many other product categories.

EU Battery Regulation at a Glance

For manufacturers, importers, and distributors of batteries, understanding the Battery Regulation's DPP requirements is not optional. Compliance deadlines are approaching rapidly, and the complexity of the data collection and management challenges involved means that preparation must begin well in advance. This article provides a comprehensive overview of what the regulation requires and how businesses can prepare.

Scope and Battery Categories

The Battery Regulation applies to all batteries placed on the EU market, regardless of their chemistry, shape, volume, weight, or design. However, the DPP requirements do not apply uniformly to all battery types. The regulation distinguishes between several categories of batteries, each subject to different compliance obligations.

The battery categories and their DPP relevance are:

• Portable batteries: general-purpose batteries used in consumer devices, not subject to battery passport requirements but subject to labelling and information obligations
• Light means of transport (LMT) batteries: batteries used in electric scooters, e-bikes, and similar vehicles, subject to battery passport requirements from February 2027
• Starting, lighting, and ignition (SLI) batteries: automotive starter batteries, subject to certain information requirements but not full passport obligations
• Industrial batteries: batteries used in industrial applications, those with capacity above 2 kWh are subject to battery passport requirements from February 2027
• Electric vehicle (EV) batteries: batteries designed for propulsion of electric vehicles, subject to the most comprehensive passport requirements from February 2027

For a deeper look at how battery passports fit within the broader ESPR framework, see our article on battery passport requirements under the ESPR, which examines the technical specifications and data standards in detail.

Battery Passport Data Requirements

The battery passport must contain a comprehensive set of data covering the battery's identity, composition, performance, and sustainability characteristics. The regulation and its implementing acts specify detailed data fields that must be populated for each battery passport, creating a rich digital record that accompanies the battery throughout its lifecycle.

The core data categories required in a battery passport include general information such as the manufacturer's identity, battery model, manufacturing date and place, weight, and unique identifier. Carbon footprint data must cover the total carbon footprint of the battery calculated in accordance with the methodology set out in the regulation, expressed as kilograms of CO2 equivalent per kWh of battery capacity, along with the carbon footprint performance class.

Supply chain due diligence information must document the manufacturer's due diligence policies for sourcing raw materials, particularly cobalt, lithium, nickel, and natural graphite. Performance and durability data must include rated capacity, expected lifetime in cycles and years, energy round-trip efficiency, and state of health parameters. Finally, composition and materials data must detail the battery chemistry, critical raw materials content, and recycled content percentages for cobalt, lead, lithium, and nickel.

This extensive data requirement means that battery manufacturers must establish robust data collection and management processes spanning their entire supply chain. The challenge is particularly acute for critical raw materials data, where supply chains often extend through multiple tiers and across several continents.

Compliance Timeline and Phased Implementation

The Battery Regulation's DPP requirements are being implemented in phases, with different obligations coming into effect at different times. This phased approach is designed to give industry time to develop the necessary technical infrastructure whilst ensuring that the most impactful requirements are introduced as quickly as possible.

The key compliance milestones are:

• 18 February 2025 (target): carbon footprint declarations for EV batteries; 18 February 2026 for rechargeable industrial batteries above 2 kWh. Each starts 12 months after the calculation delegated act, which is not yet adopted (September 2026)
• 18 August 2027: supply chain due diligence obligations apply (Chapter VII, postponed from 18 August 2025 by Regulation (EU) 2025/1561)
• 18 August 2026 (earliest): carbon footprint performance classes for EV batteries, 18 months after the delegated act if later
• February 2027: battery passports mandatory for EV batteries, LMT batteries, and industrial batteries above 2 kWh
• 18 February 2028 (earliest): maximum carbon footprint thresholds for EV batteries, 18 months after the delegated act if later
• 18 August 2028 (earliest): recycled content documentation for batteries containing cobalt, lead, lithium or nickel, 24 months after the delegated act if later
• August 2031: minimum recycled content targets must be met for specified materials

The February 2027 deadline for battery passports is particularly significant, as it represents the first mandatory DPP requirement under any EU legislation. The experience gained from implementing battery passports will inform the development and rollout of DPP requirements under the ESPR for other product categories, making the battery sector a bellwether for the broader Digital Product Passport ecosystem.

Technical Implementation of Battery Passports

The technical implementation of battery passports involves several interconnected components that must work together to deliver a seamless, interoperable system. The regulation requires that each battery passport be accessible via a unique identifier encoded in a QR code affixed to the battery, linked to a centralised registry maintained by the European Commission.

Battery passports must be interoperable, meaning that they must use standardised data formats and protocols that allow different systems to read and process the data. The European Commission is working with standardisation bodies and industry stakeholders to develop the technical standards that will govern battery passport data exchange. These standards will specify the data model, the vocabulary, and the communication protocols that all battery passport operators must adopt.

For businesses implementing battery passport systems, the key technical considerations include selecting a DPP platform provider that supports the specific data requirements and technical standards of the Battery Regulation, establishing data collection processes that can capture the required information from multiple points in the supply chain, implementing quality assurance procedures to verify the accuracy and completeness of battery passport data, and ensuring that the battery passport system can handle updates throughout the battery's lifecycle.

Supply Chain Implications

The Battery Regulation's DPP requirements have profound implications for battery supply chains. The breadth and depth of data required for battery passports mean that manufacturers cannot comply in isolation; they must engage their entire supply chain in the data collection effort, from raw material miners through to cell and pack manufacturers.

Due diligence requirements for critical raw materials are particularly demanding. Battery manufacturers must implement supply chain due diligence policies aligned with international standards, such as the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas. They must verify the provenance of cobalt, lithium, nickel, and natural graphite used in their batteries and report this information through the battery passport.

The recycled content requirements add another layer of supply chain complexity. Manufacturers must track the recycled content of specific materials in their batteries and report this through the passport, with mandatory minimum thresholds applying from 2031. This requires establishing traceability systems that can verify the recycled origin of materials throughout the supply chain, a challenge that is driving investment in digital traceability solutions such as blockchain-based material tracking platforms.

These supply chain requirements are creating new dynamics in the battery industry. Suppliers that can provide comprehensive, verified data about their materials are gaining a competitive advantage, whilst those that cannot risk being excluded from supply chains serving the EU market.

Second-Life Applications and End-of-Life Management

One of the Battery Regulation's most innovative features is its provisions for second-life applications and end-of-life management, both of which are closely tied to the battery passport. As EV batteries reach the end of their automotive life, they often retain significant energy storage capacity that can be utilised in less demanding applications, such as stationary energy storage. The battery passport plays a crucial role in enabling these second-life applications by providing the data needed to assess a battery's remaining capacity and suitability for repurposing.

When a battery is repurposed for a second-life application, the battery passport must be updated to reflect the change in status, including any changes to the battery's performance characteristics and the identity of the new economic operator responsible for it. This requirement ensures that the passport remains a living document that tracks the battery throughout its entire lifecycle, from first use through second life to final recycling.

At the end of the battery's useful life, the passport provides recyclers with the information they need to process the battery safely and efficiently. Data about battery chemistry, composition, and any hazardous substances present enables recyclers to select the appropriate processing technologies and maximise material recovery rates. This is directly aligned with the circular economy objectives that underpin both the Battery Regulation and the ESPR.

Preparing for Battery Passport Compliance

With the February 2027 deadline for mandatory battery passports approaching, businesses in the battery value chain must accelerate their preparation efforts. The most important steps include conducting a comprehensive data gap analysis to identify where current data collection processes fall short of passport requirements, engaging supply chain partners early to establish data sharing agreements and technical interfaces, selecting and implementing a battery passport platform that meets the regulation's technical specifications, and running pilot projects to test data collection, validation, and passport generation processes before the mandatory compliance date.

The organisations that approach battery passport compliance as a strategic opportunity rather than a regulatory burden will be best positioned for success. A well-implemented battery passport system not only satisfies regulatory requirements but also provides valuable data for product development, quality management, and customer engagement. In an industry where sustainability credentials are increasingly important to consumers and fleet operators alike, the battery passport is becoming a key competitive differentiator.

10-Step Action Plan for EU Battery Regulation Compliance

1. Map your battery portfolio against the regulation's categories. Portable, LMT, industrial, EV, SLI. Each category has different obligations and timelines.
2. Document supply chain due diligence. Required from 18 August 2027 for cobalt, lithium, natural graphite, and nickel. Cover all four risks: human rights, child labour, environmental, integrity.
3. Build carbon footprint calculation infrastructure. Target date 18 February 2025 for EV batteries, deferred until 12 months after the calculation delegated act is adopted; align with the Commission's methodology and select a verifier.
4. Engage cell suppliers on recycled content. Targets bite from 2031. Establish chain-of-custody documentation now to support claims later.
5. Prepare for the battery passport from 18 February 2027. This is the major data infrastructure investment. Cannot be built in months.
6. Plan for state-of-health reporting. Battery passports carry dynamic data. Design the data flow from battery management systems to the passport.
7. Update labelling and conformity declarations. The CE marking process, technical files, and product labels all change under the new regulation.
8. Coordinate with vehicle manufacturers. If you supply batteries to automotive OEMs, they will read your passport into their own systems, and into the Digital Circularity Vehicle Passport that the End-of-Life Vehicles Regulation (EU) 2026/1738 requires for every new vehicle from 1 September 2032. Align data formats and APIs.
9. Track member state enforcement priorities. Market surveillance is delegated to member states. Each may set different inspection priorities.
10. Update aftermarket and end-of-life contracts. Producers retain responsibility for end-of-life. Update contracts with collection networks and recyclers.
