Example battery passport of a stationary storage battery

What a battery passport looks like: public information of a fictitious home storage battery, protected tiers, later obligations and the signature.

This page shows a battery passport as BatteryPass publishes it, with fictitious data for a home storage battery. It is not a real passport: the QR code and the address point to an example domain, and the manufacturer does not exist. The field names come from our field registry.

Required later

The carbon footprint and the recycled content follow once the delegated acts apply. Until then the passport shows what it is waiting for instead of an empty line.

Due diligence: from 18 August 2027, for companies above the turnover threshold

🔒 For authorised parties only

The passport shows these details only to persons with a legitimate interest and to authorities. The public only sees that they exist.

  • Material composition (cathode/anode/electrolyte)
  • Dismantling / removal documents
  • Spare part sources
  • Safety instructions
  • Remaining capacity
  • Number of full cycles
  • Negative events (accidents etc.)
  • Test reports proving compliance

Signature

Version 3, signed with Ed25519 (key ex-2026-10, example). Every earlier version stays retrievable by date.

What you see here

  • Public information is visible to anyone who scans the QR code: manufacturer, category, chemistry, performance values, end-of-life information and the declaration of conformity.
  • Protected information such as the detailed composition, dismantling documents and condition data is shown only to authorised parties; the public only sees that it exists.
  • Later obligations such as the carbon footprint appear in the passport with their trigger instead of as an empty line.
  • The signature proves that the passport was published this way; earlier versions stay retrievable by date.

How this information comes from your data is shown on the Product page. Which batteries need a passport is covered in the article on stationary storage.
