Key takeaways
- ●Access is tied to specific fields and purposes, not a simple public/private switch.
- ●Batteries define three audiences: public, legitimate interest, authorities.
- ●Internal admin and supplier roles are operational, not legal tiers.
Battery passport audiences
- General public — identity, chemistry, carbon footprint, recycled content, capacity, lifetime, warranty
- Persons with legitimate interest — repairers, remanufacturers, second-life operators and recyclers: detailed composition, dismantling, state of health
- Notified bodies, market surveillance authorities and the Commission — test reports and compliance evidence
Example permission matrix
| Field | Public | Repairer | Recycler | Authority |
|---|---|---|---|---|
| Model & manufacturer | Read | Read | Read | Read |
| Carbon footprint | Read | Read | Read | Read |
| Detailed composition | — | Read | Read | Read |
| Dismantling instructions | — | Read | Read | Read |
| State of health | — | Read | Read | Read |
| Test reports | — | — | — | Read |
Design tip
Model each permission as field × audience × read/write × purpose × proof of entitlement. Verifiable credentials and identity wallets are emerging as a way to prove a repairer or recycler is entitled to restricted data.
