Subway emergency power packs: Battery Passport & Marketplace End-of-Life Guide

Subway emergency power packs need dual infrastructure: Annex XIII passports for EU compliance and a liquid path for retired metro backup packs. PassCell combines both on one grid.

During service life

Publish category-aware passports, allocate global serials, print QR labels, and keep SoH current via dashboard or API so second-life buyers can trust telemetry later.

At end of life

List verified packs on Lane A when SoH supports repurposing. Route depleted metro backup packs to Lane B recycler bids. Operators without passports use free Independent Collector salvage listings.

EPR value

Marketplace bid history tied to passport serials supports extended producer responsibility reporting for auditors and regulators.
