- battery passport transfer of ownership
Your client leaves. What happens to their battery passports?
An authorised representative losing a client does not transfer anything. The obligation never moved. Here is what actually triggers a transfer under the registry rules — and what the rules still do not say.
- unique product identifier ISO 15459
Your battery passport is only as valid as its identifier
Two regulations require the unique product identifier to follow ISO/IEC 15459. That single clause decides whether a passport is valid at all — and for some companies it means a procurement step nobody has scheduled.
- DPP registry verification

The DPP registry is live, but battery registration is not yet possible — for anyone. We completed operator verification this week; here is what is actually open, and why it is the half that matters.
- EU DPP registry live
The registry is live. What changed today, and what did not

- battery passport pricing
What battery passport compliance costs: our pricing, in the open
€5,000 a year for the platform, €25 per passport you activate. Here is the full model, worked examples included — and why we publish it when most of this market will only give you a quote.
- battery passport importer obligations
You import batteries from a non-EU maker: where you stand on 18 February 2027
From 18 February 2027, every in-scope battery you place on the EU market needs a digital passport — and as the importer, the obligation sits with you. Your position, in plain terms.
- EU 2023/1542 Annex XIII · Art. 77
Who owns each battery-passport data field?
Liability for the passport sits with one party; the data comes from the whole supply chain. A field-by-field map of who owns what.
- ESPR 2024/1781
The DPP service-provider delegated act slips to Q4 2026
What the delay means for accreditation timing, and why the binding deadline is the 18 February 2027 passport date regardless.
- EU 2023/1542 Annex XIII
Collecting the data for a battery carbon-footprint declaration: the challenges to plan for
A carbon-footprint declaration isn't a number you look up — it's a study built from plant-level primary data, a prescribed methodology, and a verification trail. Here are the data-collection challenges that follow directly from the rules.
- EN 18222 / EN 18223
The DPP standards suite, in plain terms
What the CEN/CENELEC DPP standards actually require of a passport you host — and the honest status of their adoption.
- EU 2023/1542
