EU Battery Passport Requirements: Mandatory from 18 February 2027
February 18, 2027Battery passports become mandatory for relevant batteries placed on the EU market
From 18 February 2027, every electric vehicle battery, light means of transport battery and industrial battery above 2 kWh placed on the EU market or put into service must have a battery passport under Regulation (EU) 2023/1542. The European Commission’s Digital Batteries Passport guidance, version 2.0 dated 15 August 2026, maps 71 data points across those three categories. It is an implementation aid, not a replacement for the binding Regulation, and not every point applies to every battery category or at launch.
Which batteries require a passport from February 2027
Article 77 of Regulation (EU) 2023/1542 applies the passport obligation from 18 February 2027 to electric vehicle batteries, light means of transport batteries and industrial batteries with a capacity greater than 2 kWh that are placed on the EU market or put into service. Other battery classes do not become passport batteries merely because the Commission’s data-point guidance discusses battery information.
The 71 data points are an applicability map, not one flat checklist
The Commission’s August 2026 guidance classifies each of 71 data points for EV, LMT and industrial batteries above 2 kWh as mandatory, optional, conditional, deferred or not to be filled and displayed. Manufacturers should determine applicability point by point for the correct battery category. The guidance supports a common interpretation and may evolve; it does not create additional legal requirements beyond the Regulation and applicable delegated or implementing acts.
Core identity and manufacturing information
The preparation set covers the unique battery identifier, the economic operator responsible for registration, manufacturer information, battery category, model, batch or serial information, manufacturing plant location, month and year of manufacture, battery weight, rated capacity, chemistry, hazardous substances, suitable extinguishing agents and critical raw materials present above the relevant threshold. These values should be stored as structured data rather than buried in a document.
Performance and durability depend on battery category
The catalogue includes voltage, power capability, expected lifetime, storage conditions, warranty period, energy efficiency, internal resistance, conformity markings, the EU Declaration of Conformity and waste-management information. Applicability differs between EV, LMT and industrial batteries, so a single generic form should not force every field onto every battery.
Detailed composition, repair and compliance evidence
The guidance also maps detailed cathode, anode and electrolyte composition, component part numbers and sources for replacement parts, dismantling information, diagrams, sequences, tools, warnings and cell layout, safety measures and compliance test reports. Access controls and evidence handling should be designed before these records are published.
Separate static product data from dynamic lifecycle data
Data points 51 to 71 cover information that can change after manufacture, including capacity and power fade, internal resistance, round-trip efficiency, expected lifetime, remaining performance, battery status, cycle count, negative events, operating conditions, temperature and state of charge. A passport system should keep this lifecycle stream separate from stable identity and manufacturing facts while preserving an auditable history.
EV, LMT and industrial state-of-health fields are different
State-of-health information is category-specific. State of certified energy is used for EV batteries. Remaining capacity, power capability, round-trip efficiency, self-discharge and ohmic resistance apply to LMT batteries and can be conditional for industrial batteries where those parameters are relevant to the battery’s intended use. Category rules should drive both data collection and display.
Do not publish deferred or duplicate items prematurely
The August 2026 map identifies items that should not yet be treated as launch-day requirements. Material composition and rated capacity contain duplicate entries that should not be filled and displayed twice. Carbon-footprint declaration and class-label fields remain deferred pending implementing measures; responsible-sourcing due-diligence information applies from 18 August 2027; recovered cobalt, lithium, nickel and lead shares depend on later measures; and electronic instructions remain on hold pending the relevant legislative change.
Support controlled access
Battery passport data does not all have the same audience. Public information, information reserved for notified bodies, market-surveillance authorities and the Commission, and information available to parties with a legitimate interest must be modelled separately. Confidential composition, repair, safety and compliance evidence should not be exposed indiscriminately.
Use a durable identifier, QR carrier and destination
The physical data carrier must resolve to a stable digital record for the battery. Model the unique battery identifier separately from the stable hosted passport URL, and ensure that lifecycle updates, corrections or status changes do not require the QR code attached to the product to be replaced.
Keep binding law and implementation guidance separate
Regulation (EU) 2023/1542 is the binding legal source. The Commission’s Digital Batteries Passport data-point guidance explains category applicability as understood in August 2026, but it is non-binding, may be revised and must be read together with delegated and implementing acts. Compliance decisions should always be checked against the latest official legal instruments.
How often must battery lifecycle data be updated?
Update relevant dynamic data when a status change occurs or is considered. More frequent monitoring can be needed where feasible and proportionate; continuous real-time telemetry is not universally required. Offline battery servicing can be an appropriate update point. New batteries may initially lack use-generated data, but status and applicable performance and durability values must be provided.
Is all battery passport information public?
No. Public information and restricted information have different audiences. DPPora’s existing controls cover organisation-reviewed authority access to compliance test reports; other restricted access rights await final EU rules. These controls are not EU verification or a guarantee of compliance with the forthcoming access act. Do not publish confidential evidence in the public record.
Does automatic translation ensure language compliance?
No. Non-language-neutral information must meet the language requirements of the Member State where the battery is marketed. The responsible economic operator must check the required languages and translation accuracy. Multilingual display alone does not establish compliance.
What manufacturers should prepare now
Classify each in-scope battery correctly; map all 71 guidance points to mandatory, conditional, deferred or not-applicable status; assign a data owner and source for each applicable point; separate static and dynamic records; define access levels; retain supporting evidence and version history; and monitor the outstanding carbon-footprint, recycled-content, electronic-instruction and due-diligence measures before production rollout.
