1. Gather your battery data
Collect chemistry, nominal voltage, capacity, weight, carbon-footprint figures, recycled-content percentages and supply-chain due-diligence information. This is the part to start early.
2. Define the battery model
Enter the model-static data once. Every battery of that model inherits it.
3. Issue a passport per physical battery
Generate one passport per unit, each with an ISO/IEC 15459-compliant unique identifier. This is the Article 77(1) requirement.
4. Set the access tiers
Assign each field to its Annex XIII tier — public, legitimate interest, authorities, or Commission — so the public page never leaks restricted data.
5. Generate the QR code
Produce a print-grade QR code (high error correction, at least 1024px) pointing at the permanent passport URL, ready for the physical label.
6. Publish the public page
Publish the passport at a stable URL that will not change for the 10-year retention period.
7. Keep lifecycle data current
Update item-dynamic data — state of health, status, repurposing or recycling events — over the battery’s life. Repurposing forks a new linked passport; recycling ends the passport.
