Visibility
Each reader sees the part the law gives them.
An authority sees test reports that nobody else does. A reader with a legitimate interest sees the individual battery's own history, which the authority does not. Pick a reader below to see which parts of the passport they can read.
Everything on this page comes from Regulation (EU) 2023/1542, Art. 77(2) and Annex XIII, quoted from the consolidated text. It covers the battery passport only; the note at the foot of the page explains why that matters.
Legal basis: Art. 77(2)(a)
Point 1: public information about the battery model
VisibleMaterial composition, carbon footprint, recycled content, rated capacity, expected lifetime, declaration of conformity, waste management information.
Point 2: model information for readers with a legitimate interest, and the Commission
WithheldDetailed composition, part numbers and where to get spare parts, dismantling information, and safety measures.
Point 3: evidence of conformity
Withheld"Results of test reports proving compliance with the requirements laid down in this Regulation".
Authorities only. Not shown to readers with a legitimate interest.
Point 4: the individual battery's own history
WithheldState of health, battery status, and "data resulting from its use, including the number of charging and discharging cycles and negative events, such as accidents, as well as periodically recorded information on the operating environmental conditions, including temperature, and on the state of charge".
Legitimate interest only. Not shown to authorities.
Why it is not a ladder
Two readers, two different parts of the passport.
Art. 77(2) gives points 2 and 3 to notified bodies, market surveillance authorities and the Commission, and points 2 and 4 to readers with a legitimate interest.
A legitimate interest is limited. The Regulation grants it for two purposes only: dismantling and composition work by repairers, remanufacturers, second-life operators and recyclers; or, for an individual battery, its buyer (or someone acting for them) making it available to independent energy aggregators or energy market participants.
Point 3 is missing from the second list. Point 4 is missing from the first. No ranking can express that, so no simple access level can either. Software that puts the regulator at the top of a ladder gives the wrong answer for point 4.
Point 4 is the individual battery's own use history: charge cycles, accidents, temperature, state of charge. For an electric vehicle that is a usage record of an identifiable vehicle. Showing it to a reader the law does not give it to would disclose personal data.
Scope
This is the battery passport, and only the battery passport.
ESPR does not impose this split. Art. 11(b) gives each reader access "based on their respective access rights set out in the applicable delegated act adopted pursuant to Article 4", so who sees what belongs to each product group's own rules.
For batteries, the Battery Regulation sets the split itself, and it is quoted above. For textiles, electronics, furniture and most other groups, no such rules have been adopted, so there is no split between authorities and legitimate interest to show. Until there is, the software keeps it simple: a few fields are shown only to readers with a credential, and every other field is public. It does not guess which reader the law will favour.
A single set of access levels applied to every group would treat the battery rules as if they applied to all products.
