18 February 2027. Every battery on the EU market needs a passport.
CellHash generates, hosts and registers the battery passport for the e-bike brands, storage makers and importers that enterprise vendors do not serve. Designed around the EU regulation, ready for the UK's aligned regime.
Counted live to 18 February 2027, Brussels time. The Commission reaffirmed the date in May 2026 and the Council's June 2026 omnibus mandate keeps it.
Not a reporting exercise. A condition of placing a battery on the market.
Six duties in the Regulation, each with a date and an article number. CellHash is built to discharge all of them from one record.
A passport per battery
From 18 February 2027 each light-means-of-transport battery, each industrial battery above 2 kWh and each EV battery placed on the market or put into service must have an electronic record: the battery passport.
A QR code on the battery
Every battery carries a high-contrast QR code readable by a phone. For in-scope batteries it must open the passport through a unique identifier compliant with ISO/IEC 15459.
Registered in Brussels
The identifier must be uploaded to the EU Digital Product Passport Registry, mandatory for these batteries from 18 February 2027. Customs can check it.
Four access tiers
Public model data; model data for persons with a legitimate interest; data for notified bodies and authorities; and individual-battery data such as state of health.
Hosting that outlives the seller
Data is stored by the economic operator or an operator authorised on its behalf, and must remain available after the operator ceases to exist or leaves the Union.
Enforced through CE marking
Labelling and information duties are conditions of conformity behind the CE mark. Non-compliance means corrective action, withdrawal or recall. Member states had to set penalties by 18 August 2025.

The duty sits with whoever places the battery on the EU market.
Three categories, millions of units a year, and the cost falls hardest on the small companies without a compliance team.
E-bike and light-transport brands
Mostly SME brands and importers, with packs sourced from Asia and no compliance team. The Battery Pass consortium calls the market fragmented, SME-heavy and low-margin per battery, and recommends battery-passport-as-a-service providers.
For e-bike brands →Home and commercial storage makers
Storage system makers, integrators and importers. Every home battery above 2 kWh is in scope. No vendor specifically serving home-storage makers was found in a September 2026 comparison.
For storage makers →EU importers and subsidiaries
Non-EU makers cannot sell without an EU-hosted passport. Their importers and EU subsidiaries carry the liability, and Article 78 says the record must survive the seller.
For importers →UK exporters to the EU and Northern Ireland
Northern Ireland is already inside the EU regime. Great Britain is consulting on an aligned regime. UK exporters face the EU rules now and a GB regime later.
For UK companies →Upload what you have. See what the regulation still needs. Get the passport.
No system to replace. CellHash takes the data a manufacturer or importer already holds and produces the artefacts the law names.
Upload the data you hold
Bill of materials, cell supplier data, declarations of conformity, test reports, supplier attestations and BMS exports. CSV and API intake with column mapping.

Every one of the Commission's 71 data points scored as mandatory, optional, conditional or not required in February 2027, per access tier.
Generate the passport
Passport page with four access tiers, ISO/IEC 15459 identifier, QR code, versioned snapshot and Asset Administration Shell record, in bulk for a production run.
We register and host it
Entry in the EU DPP Registry through the registry API, and EU-resident hosting as authorised operator for as long as the law requires.
Passport-as-a-service for the batteries the enterprise vendors skip.
Europe has passport vendors. Almost all of them sell to enterprises, and almost none publish a price. We are built for a 50 to 500 person company that must comply on a date it cannot move.
- ✓Generates the artefact. Passport page, identifier, QR, registry entry, AAS record. Not a dashboard.
- ✓Hosts and registers as authorised operator, with EU-resident storage, for the life of the battery.
- ✓Priced for a small brand. Usage-based, starting under €500 a month, with published prices.
- ✓Built for LMT and storage, the two categories where the readiness gap and the fixed-cost burden are largest and no incumbent focuses.
- ✓Regulation as configuration. The GB regime arrives as a delta pack, and each later EU obligation is a pack update, not a rebuild.
- ✓Tier-aware validation. The public page, the legitimate-interest view and the authorities' view are checked separately, so you ship what is required first.
Subscription for the platform, a fee per passport, and hosting for as long as the law needs the record.
Only four of nine European platforms published a price in September 2026. We do.
The UK is aligning, not diverging. Northern Ireland is already in.
Regulation 2023/1542 has applied in Northern Ireland since 18 February 2024. On 8 July 2026 the Defra minister said the government would consult this autumn on a Great Britain regime "consistent with the EU's 2023 batteries regulation". For CellHash the UK is a delta pack: same data model, GB identifiers and reporting added when the regime is published.
