Source: Regulation (EU) 2023/1542, Art. 13(6), Art. 77, Art. 78 and Annex XIII.
Scope (Art. 77(1))
From 18 February 2027, every battery placed on the market or put into service in the following categories must have a battery passport:
- LMT battery
- industrial battery with a capacity greater than 2 kWh
- electric vehicle battery
Access is through the QR code applied to the battery (Art. 13(6)) with a unique identifier assigned by the economic operator (Art. 77(3), ISO/IEC 15459-1/-2/-3/-4/-5/-6:2014/2015).
Access levels (Art. 77(2))
| Level | Annex XIII | Who has access |
|---|---|---|
| 1 | point 1 | anyone (public) |
| 2 | point 2 | legitimate interest + notified bodies + market surveillance + Commission |
| 3 | point 3 | notified bodies + market surveillance + Commission |
| 4 | point 4 | legitimate interest |
Persons with a “legitimate interest” are, under Art. 77(2) third subparagraph, those who need the data for a) dismantling and determining the composition (repairers, remanufacturers, second-life battery users, recycling operators) or b) making the battery available to independent energy aggregators or energy market participants. The precise definition is left to a Commission implementing act (Art. 77(9)). The deadline for it expired on 18 August 2026; the act is not yet in force, the Commission expects it in the fourth quarter of 2026.
