A battery passport is an electronic record uniquely linked to a single physical battery, required under Article 77 of Regulation (EU) 2023/1542 from 18 February 2027 for LMT batteries, industrial batteries above 2 kWh, and electric vehicle batteries. It holds the information set out in Annex XIII, is reached through a QR code and a unique identifier, and exposes data in access tiers ranging from public to authority-only. The battery passport is the sector-specific form of the EU digital product passport.
What the battery passport must do
- Correspond to each individual battery, not a model or lot (Article 77(1)).
- Be accessible via a QR code printed or engraved on the battery, linking to the data carrier.
- Carry a unique identifier consistent with ISO/IEC 15459.
- Expose information in the access tiers defined in Annex XIII (public, legitimate interest, authority, Commission).
- Remain available for the lifetime of the battery plus the persistence period required by the Regulation, even if the operator ceases trading.
Applies from 18 February 2027 to LMT, industrial (>2 kWh) and EV batteries placed on the market or put into service.
