From February 2027, every electric-vehicle battery sold in the European Union must carry a digital passport: a QR-linked record of its carbon footprint, recycled content, due-diligence attestations and a stack of performance data, much of it reaching back two or three tiers into the supply chain. The regulation was finalised in 2023. The deadlines have not moved. The industry's readiness has not moved much either.
Lumera's readiness survey, fielded in October 2025 across 210 OEM and cell-maker compliance teams, puts average passport readiness at 34 percent against the full requirement list. The figure is not quite as alarming as it sounds — readiness is lumpy, with data-model and IT-integration work largely on track — until you ask which part is failing. It is the supplier data.
The passport is a supply-chain audit wearing a QR code
A battery passport is, in effect, an audited biography of every kilogram in the pack. The carbon footprint attribute alone requires process-energy data from cathode and anode production, most of which sits in plants in China, Korea and Japan operated by companies that have never faced a European data request. Recycled-content verification requires mass-balance records from recyclers. Due-diligence attestations reach into mining.
Our survey asked which data fields respondents considered 'critical but not yet obtainable from suppliers'. Fourteen of the twenty-two passport attributes appear on that list for the median respondent. One cell maker put it plainly in an interview: 'We have a passport platform. What we do not have is eighteen months of energy meter data from a cathode plant that answers our emails quarterly.'
A passport is only as trustworthy as the least organised supplier in the chain, and the least organised supplier knows it is suddenly negotiating from strength.
There is an industry response forming, and it looks like procurement rather than software. The two largest European OEM groups have begun writing data-delivery schedules into cell supply contracts, with payment milestones attached — which is the correct incentive and also a quiet repricing of the supply relationship. Cell makers, in turn, are discovering that their own leverage over cathode suppliers is weaker than their leverage over OEMs.
The Indian angle deserves a paragraph of its own, because it is mostly missed. India's cell projects are aimed substantially at export into European supply chains, and every one of them will face passport data requirements from its first commercial shipment. None of the four major projects' public documentation mentions passport readiness. The firms that build the data discipline now will walk into European qualification years ahead of rivals.
February 2027 will not be a cliff; the regulators have been too clear, for too long, to enforce brutally on day one. But the companies treating passports as an IT project are going to discover, in a supplier negotiation they had not planned, that it is a procurement project. The QR code is the easy part. It always was.
