What Data a Battery Passport Must Hold (Annex XIII)
A battery passport is a QR code linked to a record that starts empty. What fills it is a fixed list, and most of that list does not live in the factory that assembled the battery.
That list is Annex XIII. Filling it is the real work of a passport.
Where the requirements come from
The content of a battery passport is not left to the maker. It is set in Annex XIII of the EU Batteries Regulation, Regulation (EU) 2023/1542.
Annex XIII lists the fields every covered battery passport must carry. Think of it as the schema the passport has to fill, the same for every EV, LMT and industrial battery over 2 kWh.
What a battery passport must hold
The data falls into a few groups.
- Identity and model. Which battery this is: manufacturer, model, and a unique identifier for the individual unit.
- Composition and materials. What the battery is made of, including the critical raw materials it contains.
- Carbon footprint. The declared carbon footprint of the battery, calculated on the set method.
- Recycled content. The share of recycled cobalt, lithium, nickel and lead in the battery.
- Performance and durability. How the battery performs and how long it is expected to last.
- Supply-chain due diligence. The record behind the raw materials, showing the sourcing was checked.
- Dismantling and recycling. The information a recycler needs to take the battery apart safely at end of life.
None of this is a marketing sheet. Each field is evidence, and it has to stay accurate for the life of the battery.
The data lives across the supply chain
Almost none of that data sits in one place.
The carbon footprint comes from how the cells were made, often in another country. The recycled-content shares come from the material suppliers. The due-diligence record follows the raw materials back up the chain. The operator that places the battery on the market has to gather all of it and stand behind it.
So a passport is a data-collection exercise long before it is a QR code, the same problem CBAM importers face with emissions and EUDR operators face with plots.
Who sees what: access tiers
Not everything in the passport is public. Annex XIII data is disclosed at three access tiers.
- Public. Anyone who scans the QR code sees the general information.
- Legitimate interest. Parties with a defined need, such as recyclers and repairers, see more.
- Notified bodies and market-surveillance authorities. They see the full record.
So a single passport serves a shopper, a recycler and a regulator from the same QR code, showing each the slice they are entitled to.
How Bindu keeps the data straight
The work is collecting a fixed list of fields from across the supply chain and keeping them accurate per unit.
Bindu holds the passport template built from the Annex XIII fields, stores the evidence behind each one with an owner and a date, and publishes the passport page the QR resolves to, with the access tiers applied. The data you gather once becomes the record a buyer, a recycler or an authority scans. See the battery passport breakdown.
FAQ
What data must a battery passport contain? The information listed in Annex XIII of the EU Batteries Regulation: battery identity and model, composition and materials, carbon footprint, recycled-content shares, performance and durability, supply-chain due diligence, and dismantling and recycling information.

Is all battery passport data public? No. The data is shown at three access tiers: a public view for anyone who scans, more for parties with a legitimate interest such as recyclers, and the full record for notified bodies and market-surveillance authorities.

Where does battery passport data come from? From across the supply chain. The carbon footprint comes from cell manufacturing, recycled-content shares from material suppliers, and the due-diligence record from raw-material sourcing. The operator placing the battery on the market must gather and stand behind all of it.

Does a battery passport include a carbon footprint? Yes. A declared carbon footprint, calculated on the method set in the regulation, is one of the required Annex XIII fields for covered batteries.
