Model
Fixed for every unit of a model: chemistry, nominal capacity and voltage, the carbon-footprint class, the spec sheet a buyer compares.
Regulation (EU) 2023/1542 · Article 77 · Passport from 18 Feb 2027
The battery passport: what an operator must publish.
Chemistry, carbon, sourcing, recycled content, a living state of health: one passport carries all of it. One for every EV and LMT battery, and every industrial battery over 2 kWh, that you place on the EU market. From 18 February 2027, you cannot place one without it.
Battery passport data
The data starts at the mine, but the operator answers for all of it.
One EV battery is a mine, a refiner, a cell line and a pack plant, strung across three continents. Each holds one slice: the cobalt's origin, the cell's carbon, the plant's recycled share, the pack's living state of health. From 18 February 2027 the law wants all of it, per individual battery, and it sends the bill to the last name on the pack. That last name is the economic operator: whoever places the battery on the EU market.

- RefinerActive material

The operator sees the pack. The cell's carbon, the refiner's mix, the mine's origin: all of it stays upstream. No shared record. Just certificates, re-typed into every buyer's portal.

Regulation (EU) 2023/1542 · Article 77(5)Battery passport process
The seven steps to a battery passport.
The law asks one company for a record it doesn't hold. This is how Bindu is building it, in seven moves. Supplier collection, evidence and the audit trail run today on the EUDR filing engine. The battery passport engine is still being built, so every step below is marked planned.
01 / 07 · AskPlanned
Ask each tier for the one field it holds.
Bindu runs supplier collection this way for EUDR today. One request per party, pack plant down to the mine, each asked for the single field it holds in the format it already keeps.

Static, model data is public. The living, per-unit data opens only to a legitimate interest. Verifiable credentials hold each door; a buyer never sees the recycler's view.
Granularity
Model, batch, or unit?
A garment can pass with a batch number. A battery can't. The passport goes all the way down, one per individual unit, and the living data belongs to that single cell.
Batch
What changes run to run: the plant and date of manufacture, the recycled-content share, calculated per model, per plant, per year.
Unit
A unique identifier on every individual battery, its QR engraved on the case, and a living record: state of health, cycle count, status, the events it survives.
Recycled content, wave one. Already law.
Art. 8(2) · per model, per plant, per year · from 18 Aug 2031Wave two lifts them from 18 August 2036: cobalt 26%, lithium 12%, nickel 15%, lead held at 85%. You can only prove a recycled share you can trace to the plant that made the cell.
Battery passport deadlines
The battery passport dates are already set.
The passport binds on 18 February 2027, per unit. Around it, the feeder obligations switch on one by one. The carbon-footprint deadlines are the moving part: each lands only after a delegated act still pending. Everything else here is fixed, and 2027 is close.
The QR appears on every battery and the passport goes live, per individual unit, for EVs, industrial batteries over 2 kWh and LMT batteries.
Recycling and second life
The passport stays with the battery after the sale.
End of life is where the battery passport pays for itself. It is also where the data has always gone dark.
A recycler pulling apart a pack needs the chemistry, the joints and the hazards before the first cut, not after. State of health decides whether a used pack gets a second life or goes straight to shredding. One record survives resale, repurposing and years of wear, and still names every cell. The passport.
- chemistry unknown
- no disassembly map
- hidden hazards
- unknown state of health
- worn labels
Materials the recycler must recover.
by 31 Dec 2031 · Reg (EU) 2023/1542 Annex XIIBy end 2027 the floors are lower: lithium 50%, the rest 90%. Those recovered grams feed the recycled-content minima, and the passport tells the recycler which chemistry it is pulling apart.
Battery passport standards
The open standards underneath.
Bindu is being built onto the EU's own open standards rather than a private format. They come from Eclipse Tractus-X, the open-source stack behind Catena-X, and its building blocks are KITs, “Keep It Together”. One of them is wired today: the connector. Bindu drives a stock Eclipse Dataspace Connector, and the other blocks below are the standards the passport is being built onto, not features you can use yet. Pick one to see the job it does.

FAQ
Frequently asked questions.
An electronic record, the first Digital Product Passport (DPP) to become mandatory, required under the EU Batteries Regulation for individual batteries placed on the EU market. It is accessed via a QR code on the battery.
From 18 February 2027, under the EU Batteries Regulation.
Each electric-vehicle (EV) battery, LMT (light means of transport) battery, and industrial battery with a capacity above 2 kWh. One passport per individual battery unit.
The information listed in Annex XIII: battery identity and model, composition and materials, carbon footprint, recycled-content shares, performance and durability, supply-chain due-diligence, and dismantling and recycling information, disclosed at defined access tiers (public, legitimate interest, and notified bodies).
Yes. The battery passport is the first Digital Product Passport to take effect. Other categories, textiles among the first, follow under the Ecodesign for Sustainable Products Regulation (ESPR).

The economic operator that places the battery on the EU market, the manufacturer or the importer, is responsible for the passport and for keeping its data accurate, complete and up to date. There is one responsible operator per battery placed on the market.
No. The passport applies only to electric-vehicle batteries, LMT batteries, and industrial batteries above 2 kWh. Portable batteries, such as those in phones, laptops and power tools, fall outside the passport requirement, though other parts of the Batteries Regulation still apply to them.
Through a QR code printed on or attached to each battery, which resolves to that battery's passport. What a reader sees depends on their access tier: a public view for anyone, more for those with a legitimate interest, and the full record for notified bodies and market-surveillance authorities.
That is the passport's real work, and it is the same supplier-collection problem Bindu already runs for EUDR filings today: each party gets a link asking for the one field it holds, in the format it already keeps, with no portal account to create. What they enter lands on your dossier, attributed to them.
The template is versioned. Your collected data stays where it is; new or changed fields appear as new obligations on the checklist, so you see exactly what the updated act asks for that you have not answered yet.
In your own workspace: EU-hosted and GDPR compliant, one workspace per company. By the regulation's design, only the unique identifier goes to the EU registry, and nothing is public except the passport view you choose to publish.
Yes, but that is a separate rule from the passport. From 18 February 2027 the EU Batteries Regulation requires portable batteries in products such as phones and laptops to be readily removable and replaceable by the user. Those same portable batteries do not need a battery passport, which is reserved for EV, LMT, and industrial batteries above 2 kWh, so the two 2027 duties are easy to confuse.
Economic operators that place batteries on the EU market must run a supply-chain due-diligence policy covering raw materials such as cobalt, lithium, nickel and natural graphite. The duty was postponed to 18 August 2027 and falls on operators with net annual turnover of at least EUR 40 million, so smaller firms are exempt. For batteries that need a passport, the due-diligence information is one of the data points the passport must carry.

Operator responsibility
Start with one battery.
Article 77 lets the operator authorise another party, in writing, to keep the passport accurate and up to date. That is the role Bindu is building for. Below is what the regulation demands of whoever takes it on.
