When it comes to the content of the battery passport, every path leads to Annex XIII. The Battery Regulation (EU) 2023/1542 uses this annex to list the data that a battery passport must contain. Let us walk through it group by group, in plain terms.
1. General information
- Manufacturer identification and contact details (name, registered trade name, postal address, point of contact).
- Economic operator identifier (for example, EORI).
- Place and date of manufacture.
- Battery category (LMT, EV, industrial, SLI) and model.
2. Material composition
- Cell chemistry (for example, NMC, LFP, NCA).
- Presence of hazardous substances.
- Critical raw materials (CRM) by mass share.
- Recycled content per material: the percentage share of cobalt, lithium, nickel and lead.
3. Performance and durability
- Capacity (Ah), energy content (Wh/kWh), voltage window (min/max V).
- Internal resistance, original power (W).
- Expected lifetime (cycle count), warranty period.
- Round-trip efficiency, capacity threshold for exhaustion.
- Operating and storage temperature range.
4. Carbon footprint
- Total carbon footprint (kgCO₂e/kWh).
- Carbon footprint background document (URL).
5. Safety
- Handling precautions and safety measures.
- Hazardous-substance markings.
- Fulfilment of labelling requirements (Art. 13).
6. Individual battery data (dynamic)
Alongside the model-level data, there is instance-level, updating data:
- State of charge (SOC), state of health (SOH).
- Cycle count, usage log.
- Negative events (incidents), operating conditions.
- Status: original / reused / repurposed / remanufactured / waste.
7. Lifecycle and recycling
- Dismantling guide (URL).
- Waste handling information (Art. 74).
- Component identifiers, spare-part links.
8. Compliance documents (for certifiers)
- Test reports, certificates, audit reports, compliance documents.
- EU declaration of conformity.
Static or dynamic?
What makes Annex XIII special is that it contains both: alongside the model-level (static) data there is changing (dynamic) instance data generated during use. For a DPP platform this is a technical requirement — it must handle the updating SOH and cycle-count data.
By access group
The Annex XIII fields are not all public: the consumer sees basic data, the technician sees dismantling and state data, and the authority and certifier see the full content. The access groups in DIN DKE SPEC 99100 map exactly this.
Frequently asked questions
Are all fields mandatory?
Most are; a few are conditional (for example, EV-specific) or optional. The delegated and implementing acts provide further detail.
Where do I source the CO₂ data?
From manufacturing emissions and supplier data — this is often the longest item to obtain.
Does the dynamic data also need to be signed?
Instance-level data is also part of the authentic passport; handling the updating data is the platform's responsibility.
Annex XIII is the checklist; ReadyPass is the tool that fills it in. Our platform produces the battery passport with full Annex XIII coverage, validation and access-based views.
