DIN DKE SPEC 99100 is the content guidance for the battery passport — the document that translates the abstract requirements of the Battery Regulation (EU) 2023/1542 into a practical data model. Where the Battery Regulation says "the carbon footprint must be there", the SPEC says as which field, in what structure, and for whom.
What is DIN DKE SPEC 99100?
A SPEC (Specification) is a technical document issued by DIN/DKE through a fast-track procedure that describes the Battery Pass Data Content Model and the access logic for the battery passport. It was created by industry consensus and points towards the CEN/CENELEC horizontal DPP standards family (JTC 24).
What does it cover?
- Data content: the fields of the battery passport, grouped (general, material, performance, sustainability, safety, individual battery).
- Data levels: the distinction between model-level (static) and instance-level (dynamic) data.
- Pack/item logic: one passport at pack/item level, with the cell data embedded — not a DPP per cell.
- Access groups: who sees which fields (public/consumer, authorised persons, authorities and certifiers).
Access groups — the heart of the SPEC
One of the SPEC's most important contributions is access segmentation. The same passport presents a different view to each audience:
| Group | Typical content |
|---|---|
| Public / consumer | basic data, warranty, recycling |
| Authorised persons (technician, recycler) | dismantling, state, hazardous substances |
| Authorities and certification bodies | full Annex XIII content, due diligence |
This logic maps directly onto a DPP platform's persona views (consumer / technician / regulator / certifier).
How does it relate to Annex XIII?
Annex XIII of the Battery Regulation provides the legal field list; the SPEC organises, supplements and operationalises it (units, format, grouping). The two are used together: the law says what, the SPEC says how.
Why is it useful to the manufacturer?
1. A concrete field list against which to assess data gaps. 2. A common language with suppliers and certifiers. 3. The basis for a validatable schema — a DPP platform checks the import against the SPEC.
The future: CEN/CENELEC JTC 24
The SPEC is not the end of the road. CEN/CENELEC JTC 24 is developing a complete horizontal DPP standards family (data carrier, data exchange, access rights, persistence, security, unique identifiers — prEN 18216–18246). A well-designed data model is built so that it fits these with minimal adaptation.
Frequently asked questions
Is the SPEC mandatory?
The SPEC itself is guidance; the obligation arises from the Battery Regulation and the delegated acts. But the SPEC is the de facto practical reference.
Where can it be obtained?
Through the official DIN/DKE channels (for a fee). This article refers only to publicly available principles.
Per cell or per pack?
At pack/item level, with the cell data embedded — the SPEC makes this clear.
The SPEC is the map, ReadyPass is the vehicle. Our platform validates against the DIN DKE SPEC 99100 data model and maps the access groups onto persona views.
