For authorities
Check a passport without taking anyone's word for it.
Every passport served by Odal Node is signed by the company that issued it, with an identity on that company's own web domain. You can check the signatures and the full history yourself, without Odal and without the file leaving your machine.
What you can read
The authority part of a battery passport.
The Batteries Regulation gives notified bodies, market surveillance authorities and the Commission these parts of the passport:
Point 1: public information about the battery model
Material 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
Detailed composition, part numbers and where to get spare parts, dismantling information, and safety measures.
Point 3: evidence of conformity
"Results of test reports proving compliance with the requirements laid down in this Regulation".
The Regulation's annex heads point 2 with the Commission alone, but its Article 77 gives point 2 to notified bodies and market surveillance authorities as well. The test reports are for authorities only. The individual battery's own history goes to readers with a legitimate interest instead, such as recyclers and the battery's buyer. Visibility shows the split field by field. The toy and detergent passports name customs authorities too; their details come in later acts.
How access works
A credential from an issuer the company trusts.
The restricted parts open to a reader who presents a credential stating their role, signed by an issuer the company running the passport has chosen to trust. A company cannot vouch for an authority itself: its node refuses to issue credentials for market surveillance, customs or notified body roles, because that standing comes from a Member State.
There is no EU-wide issuer of authority credentials yet. The ecodesign rules let the Commission set out how such credentials are issued and checked, and none has been set out so far. Until then, access for an authority is arranged with each company, which adds the authority's credential issuer to the ones its node trusts.
Checking a passport
What you can confirm on your own.
That nothing was changed
The proof file carries every signature and the whole history. A single changed character is caught where it happened.
What happened, in order
Corrections, suspensions and handovers to another company are part of the signed record, not notes kept beside it.
Who signed it
Compare the identity in the file with the one the company publishes on its own web domain. That step ties the keys to the company.
Verify runs these checks in your browser, and says plainly what they do not prove.
Finding and keeping a passport
From the product, and for the long run.
The code on a product leads to its passport's public page. The EU registry of passports, which ESPR required by 19 July 2026, links a product's identifier to where its passport is held.
A battery passport must stay available even after the company responsible for it ceases to exist or leaves the EU market. Odal Node exports a passport with its signatures and full history as one signed file, which anyone can keep and check later.
