Who it covers

Three battery classes carry a passport.

Article 77 attaches a battery passport to the categories that move through complex, multi-owner lifecycles — the ones where identity is hardest to keep intact.

LMT

Light means of transport

Batteries powering e-bikes, scooters, and similar light electric vehicles placed on the EU market.

Industrial

Industrial > 2 kWh

Industrial batteries with a capacity above 2 kWh, including stationary energy storage.

Automotive

EV batteries

Electric-vehicle traction batteries, each requiring its own passport at unit level.

The gap

The data has to follow the cell to the end.

Carbon footprint, chemistry, material origin, and chain of custody must stay attached to each battery from production through recycling. But a battery changes hands many times — OEM, fleet operator, recycler, second-life integrator — and at each handoff the passport can drift from the physical unit.

When the link breaks, due-diligence and carbon claims become unverifiable exactly when they matter most.

Identity bindingUnit-level

What Aeroz does

One identity, bound across the whole lifecycle.

A dual-frequency chip carries an AES-128 identity bonded to each battery; every handoff across OEM, fleet, recycler, and second-life integrator writes an EPCIS 2.0 event to an append-only log. The Annex XIII data fields and supply-chain due-diligence stay attached to the unit, not a spreadsheet.

01 · Lifecycle identity

OEM to second life.

A unit-level identity is bonded at production and read at every stage — OEM, fleet, recycler, second-life integrator — so the passport never loses the physical battery it describes.

02 · Annex XIII inventory

The data the passport needs.

Carbon footprint, chemistry, recycled content, and origin are mapped to the Annex XIII data inventory and bound to the unit on an append-only EPCIS 2.0 ledger.

03 · Due-diligence mapping

Provenance you can defend.

Supply-chain due-diligence obligations are mapped to traceable custody, so origin and responsible-sourcing claims are backed by the unit's own record.

What data you gain

A passport that holds across owners.

Authenticity events

Every verification — where, when, pass or fail — on the append-only log.

Custody chain

OEM, fleet, recycler, and second-life handoffs as signed EPCIS 2.0 events.

Carbon & chemistry

Footprint and composition bound to the unit per Annex XIII.

Material origin

Responsible-sourcing provenance tied to the battery, not a batch sheet.

State-of-health events

Service, repurposing, and second-life status written to the same record.

Regulator exports

Annex XIII fields and due-diligence custody, generated from one log.

EU Battery Passport audit
