Reg. (EU) 2023/1542 · industrial batteries >2 kWh in Article 77 scope · from 18 February 2027 · second-life linkage under Art 77(7).
Grid-scale and commercial energy storage runs on exactly the batteries Article 77 covers: industrial batteries above 2 kWh. From 18 February 2027 they need passports — and because storage is where retired EV packs go for a second life, storage integrators inherit the Article 77(7) linked-passport problem more than anyone else in the chain.
Composition, capacity, expected lifetime and performance data, QR-accessible — for each battery placed on the EU market from the date.
Annex XIII expects state-of-health and operating data over time. A 15-year storage asset needs a passport platform, not a shipping label.
Racks built from repurposed EV modules need new passports linked to every donor pack's passport — Article 77(7)'s many-to-one requirement lands hardest on storage.
Modules get replaced across a storage system's life. Identity at module level is what keeps the passport truthful after year three's first swap-outs.
Storage projects commissioning after February 2027 will procure passported batteries; projects using second-life modules need genealogy from donors that retire before then. Procurement teams feel this before compliance teams do.
BESS integrators buying cells and modules for 2027 delivery should require passport data readiness in supplier contracts today.
Tag modules at intake — new or harvested — so the system passport assembles from evidence, not spreadsheets.
Decide how BMS data reaches the passport record. Annex XIII's operating-data expectations assume that pipe exists.
Aeroz gives packs and modules chip-bound identities with custody written as EPCIS 2.0 events — harvest, test, rebuild, commission, swap. The storage system's passport links to its donors because the log proves it, and every module in the rack can be verified with a tap for the life of the asset.
Industrial batteries with capacity above 2 kWh placed on the EU market from 18 February 2027 — which covers essentially all commercial and grid-scale storage units.
Directly: a repurposed battery needs a new passport linked to the original passports under Article 77(7). Storage is the main destination for retired EV packs, so integrators own this problem.
No — the BMS is a data source, not the passport. The passport is a regulated, QR-accessible record with defined content; a well-designed system feeds it from the BMS.
The passport should reflect the battery as it exists. Module-level identity makes replacements an append to the record rather than a divergence from it.
A fixed-fee Aeroz audit maps your products against battery passport for energy storage requirements and returns a written readiness assessment, a data-mapping review, and a scoped pilot plan with cost and timeline.
