A battery model holds the data every battery of one design shares — the model-level data points of Annex VI and Annex XIII. Values live in fields, keyed by the names in the field catalogue; category, capacityKwh and chemistry are properties of the model itself.

A model must be complete for its category before its passports can be published. GET /models/{id}/completeness tells you what is missing; POST /models/validate asks the same question about a draft before anything is stored.

Personalise the samples. Paste a test key and every snippet uses it — and your own model and passport ids.

GET/v1/models
read scope

List models

Your battery models, newest first, a page at a time — each with its completeness for its category and how many batteries it has and how many are published. Filter by category, completeness, or updated_since to sync only what changed.

    Page size, 1–200. Default 50.

  • cursorstringqueryoptional

    The next_cursor of the previous page. Omit for the first page.

  • category"EV" | "LMT" | "INDUSTRIAL"queryoptional

    Only models of this category.

POST/v1/models
write scope

Create a model

Creates a battery model. Industrial batteries are in passport scope only above 2 kWh (Art. 77(1)), so an INDUSTRIAL model with capacityKwh of 2 or less is refused.

Request body7

  • category"EV" | "LMT" | "INDUSTRIAL"required

    Battery category. Decides which data points are required.

  • namestring, 1–200required

    Your name for the model.

  • capacityKwhnumber > 0required

    Energy capacity in kWh. Must exceed 2 for INDUSTRIAL.

  • chemistrystring, 1–120required

    Battery chemistry (Annex VI A(7)), e.g. "Lithium-ion NMC".

  • industrialExternalStoragebooleanoptional

    Industrial battery with exclusively external storage. Default false.

  • templateKeystringoptional

    Category template. Default "battery".

  • fieldsobjectoptional

    Model-level data points keyed by API field name.

Headers2

  • Idempotency-Keystringheaderoptional

    Optional. A unique string per logical operation (a UUID is ideal). The first response is stored for 24 hours and replayed for retries; see Idempotency.

  • X-DPP-Dry-Run"true"headeroptional

    Optional, live keys. Validate the write in full and store nothing. Test keys always dry-run; see Test keys.

PATCH/v1/models/{id}
write scope

Update a model

Changes the name, chemistry or field values. fields is merged into what is stored: send only what changes, and a partial update never blanks the rest. Category and capacity cannot change — create a new model instead.

Every change is written to the audit trail.

Parameters1

  • idstringpathrequired

    The model id.

Request body3

  • namestring, 1–200optional

    New name.

  • chemistrystring, 1–120optional

    New chemistry.

  • fieldsobjectoptional

    Field values to add or replace, merged into the stored ones.

GET/v1/models/{id}/completeness
read scope

Missing-field analysis

Compares the model with the obligations of its category. missing holds required data points still empty — they block publishing. conditionalUnset holds "if applicable" ones, as prompts. Required documents (the EU Declaration of Conformity) and model properties (chemistry) are included.

Battery-level fields are answered per battery; the newest battery stands in as the sample, and with no batteries yet those fields read as unanswered.

Parameters1

  • idstringpathrequired

    The model id.

Responses

  • 200OK — The report (abridged).

Errors2

  • 401unauthorized The key is missing, unknown or revoked.
  • 404Not found No model with this id in your organisation.

POST/v1/models/validate
read scope

Validate a draft model

A stateless completeness check: send the body you would send to POST /models and get the model-level analysis back, without creating anything. unknownFields names field keys the template does not recognise — usually a typo in your mapping. Use it in an ERP form or a CI job to know whether a product record is passport-ready before it is pushed.

It changes nothing, so it needs only the read scope, and a test key gets the real analysis — not a dry-run envelope.

Request body2

  • …objectrequired

    The same body as Create a model.

  • documentTypesstring[]optional

    Documents you will upload, e.g. ["EU Declaration of Conformity"], so they count as present.

Responses

  • 200OK — The analysis (abridged).
