What data the passport needs.
Annex XIII of the regulation sets out what belongs in the passport and who may see it. Here is the overview.
Three access levels
Not all data is public. The regulation distinguishes who may view which data.
| Level | Who | Examples |
|---|---|---|
| Public | Anyone scanning the code | Manufacturer, category, chemistry, capacity, weight |
| Legitimate interest | For example recyclers and workshops | Detailed composition, part numbers, dismantling, safety |
| Authorities | Market surveillance, notified bodies, European Commission | Test reports and proof of conformity |
Static and ongoing data
Many values are fixed per model, such as chemistry or rated capacity. Others belong to the individual battery or change in operation.
- Per model: manufacturer, category, chemistry, capacity, voltage, lifetime
- Per battery: identifier, serial number, date of manufacture, batch and place
- In operation: status, state of health and events such as accidents
Data with later deadlines
For carbon footprint, recycled content and due diligence, the timing depends on the battery category and further legal acts. Check the current status in the obligation check and the EU Official Journal.
Battery passport according to DIN DKE SPEC 99100
DIN DKE SPEC 99100 “Requirements for data attributes of the battery passport” by DIN and DKE has been available free of charge since February 2025. It describes which data attributes a battery passport should contain: the mandatory information from Art. 77 and Annex XIII of the Battery Regulation plus voluntary recommendations. It is based on the “Content Guidance” of the Battery Pass consortium.
This is where you find the SPEC topics in Batterypass:
| Topic | In Batterypass |
|---|---|
| General battery and manufacturer information | Group “General information”, plus serial number, manufacturing date, batch and status per battery |
| Conformity, labelling and evidence | Group “Conformity & labelling” and uploaded evidence with SHA-256 |
| Carbon footprint | Group “CO₂ & recycled content”. The obligation applies only once the delegated act is in force |
| Supply chain due diligence | Link to the report in the passport and the due diligence module from the Pro plan |
| Material composition | Group “Materials & substances”: chemistry, hazardous substances, critical raw materials, cathode, anode, electrolyte |
| Circularity and resource efficiency | Recycled content, take-back and waste prevention, dismantling, repair and spare parts |
| Performance and durability | Group “Performance & durability” and ongoing BMS measurements such as state of health and cycles |
Batterypass covers the mandatory information under Annex XIII. The voluntary recommendations of the SPEC are only partly available as separate fields. The SPEC is a guideline; the regulation remains legally binding. DIN DKE SPEC 99100 at DIN Media
Where the data comes from
You maintain your own master data. Composition and upstream data usually come from suppliers. Ask early, because this data takes longest.
