Article 77(1) requires one passport per physical battery. Creating a battery item creates its passport and mints its unique identifier — C- followed by 11 characters — which never changes and is what the QR code resolves.

New passports are drafts: not public, not billed, until you publish them.

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

List a model's batteries

A model’s batteries with a derived display status (draft, pending, published, attention, repurposed, waste, recycled) and, for attention, the reasons. counts covers the whole model, not just the page.

This list pages by number. For syncing, prefer the cursor-paginated List passports with model_id.

Serial number or identifier, case-insensitive (contains).

Create one battery

Creates one battery and its draft passport. Battery-level data points — the Annex XIII 4(a) values measured when the battery is placed on the market — go in fields.

Moving from another provider? Send the identifier already printed on the battery as uniqueIdentifier. It is kept as-is and, because that code already resolves somewhere, the passport is published immediately if your plan allows publishing.

Request body11

modelIdstringrequired
The model this battery belongs to.
serialNumberstring, ≤ 200optional
Your serial number.
dateOfManufacturedateoptional
ISO 8601 date (data point 9).
placeOfManufacturestring, ≤ 300optional
Plant or city (data point 8). Required before publishing.
placedOnMarketAtdateoptional
Defaults to now.
putIntoServiceAtdateoptional
When it went into service, if known.
productionBatchIdstringoptional
Production batch reference.
fieldsobjectoptional
Battery-level data points keyed by API field name.
uniqueIdentifierstringoptional
Only when bringing an identifier from another provider. Omit to have one minted.
foreignResolverUrlURL, ≤ 500optional
Where the imported identifier resolves today.
importedFromstring, ≤ 200optional
Name of the previous provider, kept on the record.

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.

write scope

Create many batteries

Creates up to 1,000 batteries in one request, each with its own passport and identifier. Two shapes: count batteries numbered serialPrefix + a four-digit counter (0001, 0002, …), or explicit rows of serials you already have. When both are sent, rows wins — an existing serial is never replaced with a generated one.

The batch is created in one transaction: either every battery is created or none is. Always send an Idempotency-Key, so that a retry after a timeout cannot create the batch twice.

Request body6

modelIdstringrequired
The model.
countinteger, 1–1000optional
How many to create when rows is absent. Default 1.
serialPrefixstring, ≤ 60optional
Prefix for generated serial numbers.
placeOfManufacturestring, ≤ 300optional
Applied to every battery (rows may override).
dateOfManufacturedateoptional
Applied to every battery (rows may override).
rowsarray, ≤ 1000optional
[{ serialNumber, dateOfManufacture?, placeOfManufacture? }].
