## Summary
- EU Battery Regulation 2023/1542 requires Digital Battery Passports for industrial, EV and LMT batteries from 2027.

## Buyer Guidance
- Best for: EU Battery Passport — RFID/NFC Guide for 2027 supports RFID and NFC evaluation, comparison, and sourcing decisions.
- Compare first: Compare EU Battery Passport — RFID/NFC Guide for 2027 against reader compatibility, chip family, material, and deployment environment.
- What to confirm: Confirm target application, compatibility requirements, customization needs, quantity, and sample expectations before quoting EU Battery Passport — RFID/NFC Guide for 2027.

## FAQ
- Q: What's the deadline for EU Battery Passport compliance?
  A: February 18, 2027 for batteries >2 kWh placed on the EU market. EV, industrial and LMT categories covered. Consumer batteries (laptop, phone) excluded in the first wave but likely included in 2030+ updates.
- Q: Do I need NFC if QR is sufficient?
  A: QR satisfies the regulation literally. NFC is supplementary — useful for service technicians, easier to read from awkward angles in vehicle bays, and survives dirt that obscures printed QR. Most OEMs add NFC despite QR being adequate.
- Q: How long must the data carrier survive?
  A: 10+ years for EV and industrial batteries. Standard NFC inlays fail in 1-3 years under battery thermal cycling. Specify ceramic-substrate tags rated for AEC-Q200 automotive temperature classes.
- Q: Who owns the passport data?
  A: OEM at manufacturing, transferred to fleet operator at sale, accessible to recycler at end-of-life. The passport is a permission-based record with role-specific read/write rights, not a single-owner asset.
- Q: Did the EU Battery Regulation due-diligence date really get postponed?
  A: Yes. The original 18 August 2025 application date for due-diligence obligations was postponed to 18 August 2027 by Regulation (EU) 2025/1561, giving operators additional time to build chain-of-custody systems for cobalt, lithium, nickel and natural graphite. The Battery Passport date (18 February 2027) was not changed. Operators should plan as if the new 2027 due-diligence deadline holds, but watch for further amendments — the EU has a pattern of 6-12 month slippage on delegated acts (CEPS in-depth analysis March 2024 and ESPR Working Plan April 2025 both flag this).
- Q: Should we use Catena-X, a private blockchain or a vendor-hosted SaaS for the battery passport backend?
  A: The Regulation requires interoperable, open-standards data exchange with selective sharing — Catena-X is the reference automotive ecosystem and the safest single answer for OEM-side passport infrastructure. Pure private blockchains and single-vendor SaaS risk non-conformity unless they implement EPCIS 2.0 + GS1 Digital Link export and integrate with the EU central DPP registry (live by 19 July 2026). Practical pattern in 2025-2026 OEM pilots: passport data anchored on a decentralised ledger (Catena-X or equivalent) for immutability, with vendor SaaS handling user-facing dashboards and tag encoding workflow. Avoid black-box vendor lock-in on data portability — passport records must follow the battery through OEM → fleet operator → second-life owner → recycler.
