EV battery field reference
EV (Electric Vehicle) batteries have the most comprehensive disclosure requirements of all five battery categories under EU Battery Regulation 2023/1542. This page describes the disclosures that matter for EV batteries and their regulatory relevance.
The EV category is identified on the DPP by categoryId (cat_bat_1) and its resolvable category_code (BAT-EV-001), not by a *_BATTERY enum. See Battery categories for the authoritative, environment-scoped category list.
For the response object shape, see DPP data model overview.
Disclosures required for EV batteries
EV batteries carry the fullest set of mandatory disclosures under the regulation:
| Disclosure | Required | Regulatory relevance |
|---|---|---|
| Carbon footprint | Yes | Full lifecycle carbon footprint, with the calculation methodology declared. Third-party verification is expected. |
| Recycled content | Yes | Recovered-material content for cobalt, lithium, nickel, and lead. Minimum thresholds apply from 2031. |
| Cycle life and durability | Yes | Rated capacity, voltage, cycle life, round-trip efficiency, and operating temperature range. |
| Hazardous substances | Yes | Any substance present above 0.1% by weight. |
| Supply chain due diligence | Partial | The public due diligence policy reference is shown. Detailed sourcing data is a restricted PoLI field (see below). |
| Compliance | Yes | EU Battery Regulation conformity, REACH and RoHS status, certifications, and declaration-of-conformity reference. |
On the DPP object, carbonFootprint, recycledContent, and reparabilityScore are top-level summary numbers, not nested objects. For their exact placement and types, see the DPP data model overview.
Regulatory thresholds
For authoritative regulatory dates and scope, see Compliance → Enforcement timeline.
The platform does not enforce minimum recycled-content values at publish time. It is the operator's responsibility to ensure their declared data is accurate.
Restricted fields (PoLI access only)
The following supply chain fields are present in the DPP model but are omitted from the public API response. They are accessible only to entities with approved PoLI access:
- Detailed raw material sourcing by mine/country
- Internal audit report references
- Full supplier identity data (beyond the public due diligence policy URL)
See PoLI endpoints and the PoLI access flow integration example.
