Battery Passport
The battery passport data fields
The EU Battery Passport is the most data-heavy passport of them all — roughly 110 attributes per battery, defined under the EU Battery Regulation (2023/1542) and the technical work behind it (DIN DKE SPEC 99100). Here is what those fields actually are, and where the data comes from.
The shape of it: about 110 attributes across seven families, at model, batch or item granularity — and for many batteries it is per individual item. Each attribute needs its supporting evidence.
The seven data families
- Identity — battery identifier (via GS1 Digital Link), category, manufacturer and manufacturing site, date of placing on market.
- Chemistry & composition — cell chemistry, critical raw materials, hazardous substances.
- Performance & durability — rated and remaining capacity, power, internal resistance, expected and remaining cycle life, state of health.
- Carbon footprint — the battery's carbon footprint and performance class.
- Recycled content — recycled cobalt, nickel, lithium and lead.
- Due diligence — the supply-chain due-diligence report.
- End of life — collection, recycling and safe-handling information.
Granularity — often per item
Unlike model-level passports for many product groups, batteries frequently require item-level data (one passport per physical battery), because dynamic fields like state of health change over the battery's life. Item-level granularity is the main cost driver, and the reason data automation matters.
Where the data comes from
Most of it already exists, scattered: cell datasheets and supplier declarations (chemistry, materials, recycled content), your own test data (capacity, cycle life), an LCA (carbon footprint), and your due-diligence policy. The job is structuring and evidencing it — which is exactly what PassPer does from the documents you hold.
Who sees what
The same passport serves tiered views: a public view for consumers, a professional view for repairers and recyclers, and an authority view for market surveillance — enforced at the resolver, not by trust.
Frequently asked questions
How many data fields does the battery passport have?
Around 110 attributes per battery, across identity, chemistry, performance/durability, carbon footprint, recycled content, due diligence and end-of-life.
What data does the EU Battery Passport require?
Battery identity and chemistry, performance and state-of-health data, carbon footprint, recycled content (cobalt, nickel, lithium, lead), supply-chain due diligence, and end-of-life information.
Is battery passport data per battery or per model?
Often per individual item — dynamic fields like state of health change over a battery's life, so item-level granularity is common.
Where does battery passport data come from?
From cell datasheets and supplier declarations, your own test data, a lifecycle carbon assessment, and your due-diligence policy — assembled and evidenced into the passport.
