The battery passport for EV batteries.
The EV battery passport is the electronic record that the EU Battery Regulation (EU) 2023/1542 requires, from 18 February 2027, for every electric-vehicle battery placed on the EU market, reachable from a QR code on the battery.
From 18 February 2027, every EV battery, LMT battery and industrial battery above 2 kWh placed on the EU market must carry a battery passport — a QR-accessible record of composition, performance and lifecycle data, with the carbon footprint added once its rules apply. The date is fixed in law. What is not fixed is how packs, modules and cells stay identifiable through a 10–15 year service life.
Battery passport for EV, in three facts.
Reg. (EU) 2023/1542 · Article 77 · mandatory for EV, LMT and >2 kWh industrial batteries placed on the EU market from 18 February 2027.
From 18 February 2027 every light-means-of-transport battery, every EV battery and every industrial battery over 2 kWh placed on the EU market needs a battery passport (Regulation (EU) 2023/1542, Article 77).

What Article 77 actually demands.
A passport per battery
Unique identification with composition, capacity, performance, durability and chemistry data, accessible through the QR code required by Article 13(6) — from 18 February 2027.
A carbon footprint declaration, later
The carbon footprint declaration is not in the passport on 18 February 2027. It applies 12 months after the Commission adopts the calculation method, and the data must then be attributable to the actual battery, not the product family. Start collecting it now.
Living data, not a nameplate
Annex XIII requires lifecycle telemetry over time — state of health, cycle data, negative events. The passport is a longitudinal record maintained for years, which takes a data platform as well as a label.
Second-life linkage — Art 77(7)
A repurposed battery needs a new passport linked to the passport(s) of the original batteries. Read the plural: module-level genealogy, which pack-level marking alone cannot deliver.
The timeline, as it stands.
The battery passport is the DPP family's first fixed, unmissable date. Batteries placed on the EU market from 18 February 2027 without a compliant passport cannot lawfully be placed on the market.
Three moves that de-risk the deadline.
Fix identity at pack, module and cell
The regulation marks the pack; the economics live in the modules. Decide now how identity survives disassembly, repurposing and second life.
Stand up the data platform
Carbon footprint, telemetry, custody: passport data accrues over the battery's life. Choose infrastructure that appends events for a decade, not a launch-day PDF.
Prove one battery line end-to-end
Issue live passports for one line and walk them through a simulated border check and a simulated repurposing — before 2027 makes it an emergency.
Pack-level compliance, module-level truth.
Aeroz pairs the required QR with chip-bound identity at pack and module level, resolved through GS1 Digital Link, with every custody and lifecycle event appended to an EPCIS 2.0 log. When a pack is opened for second life, each module still knows who it is — which is exactly what Article 77(7)'s linked-passport requirement assumes and pack-only marking cannot provide.
Battery passport for EV, answered.
Which batteries need a passport from February 2027?
EV batteries, light-means-of-transport (LMT) batteries, and industrial batteries above 2 kWh placed on the EU market from 18 February 2027, under Reg. (EU) 2023/1542 Article 77.
What carrier does the battery passport require?
Article 13(6) requires a QR code from 18 February 2027, through which the passport is accessed. The regulation also empowers the Commission to approve alternative smart labels by delegated act — the door for chip carriers.
What is the Article 77(7) second-life problem?
A repurposed battery must carry a new passport linked to the passports of the original batteries it came from. That demands identity below pack level — once a pack is opened, unmarked modules have no provable origin.
Is 99.9% read-rate guaranteed?
No vendor can honestly guarantee a field read-rate. Aeroz builds to a 99.9% read-rate engineering spec at its QC gate and validates real-world performance per deployment during the pilot.
