Battery passport example: what it looks like
In the abstract the battery passport stays hard to grasp - so this guide shows a fully completed sample passport for a fictional 10 kWh home-storage battery. You see concretely what content a digital battery passport has, how the three access levels are split and what the QR code resolves to.
- A battery passport looks like a web page behind a QR code. When scanned it shows general details, performance and safety data - carbon footprint and recycled-content shares only once they apply. The rest is staggered by authorisation.
- The content spans 71 official EU data points (Version 2.0, 15 August 2026) in six blocks: identification, chemistry, carbon footprint, recycled content, performance/lifespan and due-diligence/conformity evidence. Not all of them have to be filled in February 2027.
- Three access levels: public (everyone), legitimate interest (recyclers, refurbishers) and market surveillance (authorities with full access).
- The example below is a sample with fictional values for a 10 kWh LFP home-storage battery - realistic, but not legally binding.
Example battery passport: 10 kWh home storage
This is what a completed battery passport for a stationary storage unit could look like. The Level column shows who may see each field. All values are example data:
| Data field | Example value | Level |
|---|---|---|
| Model ID | BPW-DEMO-HS10-LFP | Public |
| Manufacturer | Example Energy Ltd | Public |
| Category | Industrial battery · stationary storage (> 2 kWh) | Public |
| Chemistry | LFP - lithium iron phosphate | Public |
| Rated capacity | 10.2 kWh | Public |
| Rated voltage | 51.2 V | Public |
| Weight | 92 kg | Public |
| Carbon footprint | not yet applicable - delegated act still missing | Public |
| Recycled content lithium | not yet applicable - follows Art. 8 (from 2028) | Public |
| Recycled content cobalt | not yet applicable (LFP contains no cobalt anyway) | Public |
| Due-diligence report | Public report (Art. 52(3)) - required from August 2027 | Public |
| Material composition (detail) | Cathode, anode, electrolyte, housing - substance list | Legitimate interest |
| Dismantling information | Disassembly sequence, tools, hazard notes | Legitimate interest |
| State of Health (SoH) | 100 % at delivery · history visible | Legitimate interest |
| Declaration of conformity | CE · EU 2023/1542 | Market surveillance |
The full list of all mandatory fields from Annex XIII is explained in the guide What data goes into the battery passport?
Who sees what in the sample passport
A battery passport is not a single public page but one dataset with three visibilities. That protects trade secrets while still giving everyone the relevant basic data:
Chemistry, capacity, safety and take-back notes; from August 2027 the due-diligence report, later carbon footprint and recycled content. This level is seen by anyone who scans the QR code - customer, installer, fire brigade.
Detailed material composition, dismantling information and condition parameters (state of health). Access only for registered economic operators with a demonstrated interest.
The full dataset including conformity evidence. Exclusively for market surveillance authorities and the EU Commission.
What the QR code resolves to in the example
On the battery sits a QR code as a GS1 Digital Link. It encodes the product and serial number in the URL and leads to exactly this passport - one code per unit:
Example URL behind the QR code
https://id.batteriepasswerk.com/01/04012345678905/21/HS10-000842
01 stands for the product number (GTIN), 21 for the unit's unique serial number. Two batteries of the same model share the model data but have different serial numbers - and therefore different passports.
All rules on design, deadlines and scan targets are explained in the guide QR codes on batteries from 2027.
