Compliance with Article 77(1) is binary per battery: either an in-scope unit placed on the EU market from 18 February 2027 has a conformant passport, or it does not. This checklist turns the requirement into items you can tick off.
Readiness checklist
| Area | What must be in place | Done when |
|---|---|---|
| Scope | Confirmed the battery is LMT, industrial >2 kWh, or EV | Scope decision recorded |
| Identifier | Per-item unique identifier conforming to ISO/IEC 15459 | Every unit has a distinct ID |
| Data set | Full Annex XIII / Annex VI attribute set collected | No required field left blank |
| Access tiers | Each field mapped to public / legitimate interest / authority / Commission | Tier assignment reviewed |
| Data carrier | Print-grade QR (ISO/IEC 18004) on or with the battery | QR scans to the passport |
| Hosting | Permanent URL that survives the retention period | Slug fixed and published |
| Lifecycle | Process to update state of health, repurpose, recycle | Update path defined |
Common gaps
- Using a single model-level or batch-level passport instead of one per physical battery.
- Leaving restricted fields exposed on the public page rather than enforcing tiers server-side.
- No plan for updating dynamic data after the battery leaves the factory.
- A QR printed too small or at too low an error-correction level to survive a label.
Frequently asked
When should we start preparing the checklist?
Start with data collection now. Carbon footprint, recycled content and due-diligence data take the longest to assemble; identifiers, tiers, QR and hosting can be set up quickly once the data exists.
