The EU battery passport, issued in minutes.
The EU Battery Regulation (2023/1542) requires a digital battery passport for LMT, EV and industrial batteries above 2 kWh from 2027. Norruva turns your cell data into a verifiable passport — chemistry, carbon footprint, state of health and recycled content.

GS1 Digital Link
Resolves the on-product QR / data carrier to the passport.
How it works
From your systems to a verified passport.
Norruva connects to your BMS and supply-chain systems, validates against the battery-passport model, and anchors a record that stays current through life.
Connect your data
Pull the data you already hold from the systems you already run — no re-keying.
Validate against the model
The sector template checks every required field and flags gaps before anything is published.
Anchor & publish
Norruva anchors the passport and resolves it from the product’s QR or Digital Link, with a full audit trail.
Developers
Create a battery passport in one call.
Send the cell data to a single endpoint. Norruva validates it against the 2023/1542 model, anchors the record and returns a passport that resolves from the product QR.
- Full-parity sandbox — Test the entire flow before any live gate.
- Validated on write — Required fields are checked server-side before publish.
- Events & webhooks — A webhook fires the moment verification completes.

The consumer view
What your battery customer sees.
A technician or recycler scans the pack and reads its chemistry, health and sourcing — the record that follows the battery through every life.
- One scan, no app — the passport opens in any browser.
- Verified provenance a buyer can trust at the shelf.
- The same record recyclers and auditors read at end-of-life.

Common questions
Questions battery teams ask.
Which batteries need a battery passport?
Under Regulation (EU) 2023/1542, LMT batteries, EV batteries and industrial batteries above 2 kWh require a digital battery passport, applying from 2027.
What data must the passport carry?
Chemistry and composition, carbon footprint, recycled content, state of health and lifetime, and due-diligence information. Norruva ships a battery template covering each group.
Where does state-of-health data come from?
From your BMS or fleet telemetry. Norruva ingests it via API and keeps the passport's health and lifetime fields current — the values shown here are illustrative.
How is recycled content evidenced?
Through supplier declarations and due-diligence records linked to the passport, so cobalt, lithium, nickel and lead figures stay auditable.
