How to Get an EU Battery Passport: Data Checklist

Manufacturers searching for how to get an EU battery passport often underestimate the data gathering required before a single QR code can be printed. This practical EU battery passport data checklist walks through every data category, verification step, and integration decision — from factory floor to public registry.

Step 1: Confirm Your Battery Category

Annex XIII requirements vary by category. Identify whether your product is EV traction, industrial (>2 kWh), or LMT — each has distinct fields and deadlines. See our category guides for EV, industrial BESS, and LMT batteries.

Step 2: EU Battery Passport Data Checklist

Identification & labeling

• ☐ Battery unique identifier (UID) — globally unique, permanently assigned
• ☐ Manufacturer legal name, address, and EU contact point
• ☐ Battery model name and commercial designation
• ☐ Manufacturing date (YYYY-MM-DD) and facility location
• ☐ CE marking reference and declaration of conformity ID

Composition & materials

• ☐ Battery chemistry (e.g., NMC, LFP, NCA)
• ☐ Critical raw material content — cobalt, lithium, nickel, manganese
• ☐ Hazardous substances present above threshold levels
• ☐ Recycled content percentages (required for EV from 2031; prepare data now)

Carbon footprint declaration for EV batteries

• ☐ Total carbon footprint in kg CO₂e per kWh of battery capacity
• ☐ Calculation methodology per EU delegated act
• ☐ Functional unit definition and system boundaries
• ☐ Third-party verification certificate (where required by class)
• ☐ Link to full lifecycle study documentation

Performance & durability

• ☐ Rated capacity (Ah or kWh) and nominal voltage
• ☐ Power capability (kW) and expected cycle life
• ☐ Round-trip efficiency (industrial/BESS)
• ☐ Initial State of Health (SoH) at manufacturing
• ☐ Temperature operating range

Supply chain & due diligence

• ☐ Due diligence policy summary per Regulation (EU) 2025/1561
• ☐ Risk assessment for cobalt, lithium, nickel, and natural graphite
• ☐ Cell supplier data sharing agreements in place
• ☐ Upstream supplier audit evidence (restricted access)

Step 3: Carbon Footprint & Lifecycle Impact Assessment

A carbon footprint declaration for EV batteries requires a full lifecycle assessment (LCA) covering raw material extraction, cell manufacturing, pack assembly, transport, and end-of-life scenarios. Many manufacturers engage battery lifecycle impact assessment services from specialized LCA consultancies to produce ISO 14040/14044 compliant studies.

Plan 3–6 months for a first LCA if you have not previously quantified embodied emissions for your battery line.

Step 4: Third-Party Verification

Third-party verification for battery passport data — particularly carbon footprint claims — adds credibility and may be required depending on battery class and implementing act provisions. Accredited verifiers review your LCA methodology, data sources, and calculations before issuing a certificate referenced in the passport.

Step 5: Choose Platform & Publish

1. Register on a battery passport compliance platform
2. Enter or import checklist data via dashboard or API
3. Allocate UID and generate QR code
4. Commit passport to public registry
5. Print label and attach to battery before EU shipment

Download Battery Passport API Documentation

For automated production lines, API integration eliminates manual data entry. PassCell Growth and Enterprise plans include REST API access for:

• POST /passports — create and publish a new passport
• GET /passports/{uid} — retrieve passport record
• PATCH /passports/{uid} — update lifecycle fields (SoH, etc.)
• POST /serials/allocate — reserve UID ranges for batch production
