The European Union's Battery Passport - the first mandatory application of the Digital Product Passport framework - will require every electric vehicle and industrial battery above 2 kWh placed on the EU market to carry a verifiable digital record from 18 February 2027. The mandate compels OEMs, Tier 1, and Tier 2 suppliers to overhaul data collection, labeling, and traceability systems across borders.
Anchored in Regulation (EU) 2023/1542, the measure applies regardless of where a battery is manufactured, meaning non-EU producers must also comply to sell into the European market. The scope covers electric vehicle (EV) batteries, light means of transport (LMT) batteries, and industrial batteries with a capacity above 2 kWh - categories central to the automotive sector's electrification push.
Background
The Battery Passport sits within the EU's broader Digital Product Passport initiative, grounded in the Ecodesign for Sustainable Products Regulation (ESPR), Regulation (EU) 2024/1781. Regulators designed the DPP framework to enhance traceability and circularity across product categories. Batteries were selected as the first mandatory implementation given their reliance on critical raw materials such as lithium and cobalt and their significance to the EU's climate strategy.
The previous Battery Directive (2006/66/EC) was fully repealed on 18 August 2025, with the new regulation now serving as the sole legislative reference. Compliance obligations are staggered: EV battery manufacturers were required to declare carbon footprints from 18 February 2025, while rechargeable industrial batteries above 2 kWh face the same carbon footprint declaration requirement from 18 February 2026. Due diligence obligations, originally set for August 2025, were postponed to 18 August 2027 under Regulation (EU) 2025/1561, giving economic operators additional preparation time.
The Battery Pass project, an industry-led consortium funded partly by the German Federal Ministry for Economic Affairs and Climate Action, concluded in March 2025 after three years of technical groundwork. Its successor, BatteryPass-Ready, is now building a test environment to help industry validate passport solutions and assess data quality ahead of the 2027 deadline.
Details
The passport must be accessible via a QR code linked to a unique battery identifier and contain standardized data on chemical composition, carbon footprint, state of health, recycled content, and end-of-life handling. Under the regulation's requirements, all passport information must be based on open standards and in an interoperable format transferable through an open data exchange network, such as Catena-X.
Access to passport data will be tiered. Publicly available information will be open to any party, while commercially sensitive data - including detailed battery composition and dismantling procedures - will be restricted to notified bodies, market surveillance authorities, and parties with a demonstrated legitimate interest, such as repairers, remanufacturers, and recyclers.
For automotive supply chains, the data burden is substantial. According to Informatica, 60-80% of the data required for a compliant battery passport originates from suppliers across multiple tiers, with no single entity holding all necessary information. An OEM's passport alone requires inputs spanning battery cell manufacturers at Tier 1 through raw material miners at Tier 3. Internal product data is typically fragmented across ERP, PLM, and sustainability systems, making manual reconciliation unscalable.
Industry experts and a Centre for European Policy Studies analysis have flagged the 2027 timeline as potentially ambitious, noting that harmonized standards for data interoperability are not yet extensively adopted across global battery supply chains. Eight harmonized European standards for the DPP data and interoperability framework are expected to be completed by 2026, according to a European standards working group. A central EU DPP registry is also expected to be operational by mid-2026.
The regulation carries direct implications for recycling streams. Material recovery targets for lithium recycling are set at 50% by 2027, rising to 80% by 2031. From 18 August 2031, batteries placed on the EU market must meet minimum recycled content thresholds for cobalt, lead, lithium, and nickel.
Outlook
The European Commission is expected to publish operational implementation guidelines by 26 July 2026, with an implementing act to follow by 18 August 2026. Supply chain due diligence obligations - covering risk mapping, grievance mechanisms, and public reporting for critical raw materials including cobalt, lithium, nickel, and natural graphite - take effect for large companies from August 2027. Automotive suppliers that delay multi-tier data collection risk being unable to establish credible processes before both deadlines converge. LMT batteries face a later passport deadline of 18 August 2028, though planning and infrastructure investment will need to begin well in advance.
