What is the EU Battery Passport?
The Battery Passport is a specialized Digital Product Passport for batteries, mandated by the EU Battery Regulation (EU 2023/1542). It brings together passport data on identity, performance, materials, carbon footprint, use and recycling and makes it digitally accessible via a QR code with a unique battery identifier. From 18 February 2027, the Battery Passport is mandatory for LMT and electric vehicle batteries, plus industrial batteries above 2 kWh.
Unlike other DPP categories, the Battery Regulation requires an individual passport per battery unit with a unique battery identifier — not just per model or SKU. More about the Digital Product Passport →
Which batteries are affected?
The Battery Regulation applies to all batteries placed on the EU market. The passport requirement from February 2027 specifically covers:
- Industrial batteries over 2 kWh — Stationary energy storage, drive batteries for forklifts and warehouse technology. The 2 kWh threshold applies exclusively to industrial batteries.
- Electric vehicle batteries (EV) — Traction batteries for passenger cars, commercial vehicles and e-buses — covered regardless of capacity.
- Light vehicle batteries (LMT) — E-bikes, e-scooters and light electric vehicles — also covered regardless of capacity.
Important: the 2 kWh threshold applies only to industrial batteries. EV and LMT batteries are covered regardless of capacity — a common industry misconception.
For battery and vehicle manufacturers, the industry pages for batteries and automotive are especially relevant.
Standards & data ecosystem (Catena-X, IDTA, acatech)
The EU Battery Regulation defines the "what", not the "how". Three standardization initiatives shape the technical implementation in Europe:
- Battery Pass Konsortium (acatech) — BMWK-funded consortium with industry and research partners. The technical guide and software demonstrator are important references, but they do not replace EU legal acts.
- Catena-X Automotive Network — Open, decentralized data ecosystem standard for the automotive industry. Provides the data-space backbone for EV battery passports — data stays with the owner but is exchanged interoperably.
- IDTA / Asset Administration Shell (AAS) — Industrial Digital Twin Association. Defines the submodels for battery passport data as a digital twin — compatible with Catena-X and CIRPASS-2.
- ECLASS Release 15.0+ — Provides the semantic characteristics and data structures for the battery passport — applicable across industries.
Data flow across the battery supply chain
The battery passport is built across the entire value chain. Data typically flows like this:
- 1. Raw material supplier — Provides origin, carbon footprint and recycled content for lithium, cobalt, nickel — typically as an ESG data package.
- 2. Cell manufacturer — Aggregates material and production data per cell batch. Hands over structured data via Catena-X or bilateral APIs.
- 3. Pack assembler / OEM — Links cell data to the unique battery identifier and adds production and QA data.
- 4. DPP platform — Consolidates all data, generates the final passport instance with QR code and provides role-based access.
- 5. Lifecycle phase — BMS and service systems can provide SoH, status and use-history data. Repair, second-life and recycling actors add data depending on their role and access rights.
National enforcement of the Battery Regulation
The EU Battery Regulation applies directly; national law mainly governs authorities, registration, take-back obligations and penalties. Manufacturers therefore need both layers: the substantive duties in the EU Regulation and the enforcement rules in the Member States where batteries are placed on the market.
Data and access rights in the Battery Passport
The EU Battery Regulation distinguishes public model data, authority and notified-body data, and restricted data for legitimate-interest actors such as repair, remanufacturing, second-life and recycling operators. Typical data categories include:
- Product identification — Unique battery identifier, model, manufacturer, date and place of manufacture.
- Carbon footprint & performance class — Total emissions under EU methodology and performance classes once the relevant methodology and category obligation apply.
- Recycled content — Share of recycled cobalt, lithium, nickel and lead by weight percentage.
- Origin of critical raw materials — Mining country and suppliers for cobalt, lithium, nickel — due diligence records.
- Durability & performance parameters — Capacity, State of Health (SoH), charge cycles, energy density.
- Recycling potential — Information for dismantling facilities and recyclers — including technical detail data depending on access rights.
Carbon footprint declaration
The carbon footprint declaration is a central precursor to the full Battery Passport. The EU Battery Regulation phases in requirements for calculation, declaration and performance classes by battery category; exact methods and formats depend on the relevant implementing and delegated acts.
Penalties for non-compliance
The EU Battery Regulation leaves penalties to Member States. Depending on national implementation, fines, market withdrawal, distribution restrictions and additional checks by business partners can become relevant. There is no single EU-wide fixed fine amount.
