A battery rarely stays in one role for its whole life. The regulation treats repurposing and remanufacturing as creating a new battery, which means the passport has to model lifecycle change rather than just record static facts.
Repurposing forks a new passport
When a battery is repurposed — for example, EV cells given a second life in stationary storage — the economic operator that carries out the repurposing becomes the producer of a new battery. That battery needs its own passport with its own unique identifier, linked back to the original so the lineage is traceable.
Recycling ends the passport
Lifecycle states at a glance
| Event | Effect on passport | Identifier |
|---|---|---|
| In use | Dynamic data updated | Unchanged |
| Repurposed / remanufactured | New linked passport created | New ID, linked to original |
| Recycled | Original passport ends | Retired |
Because the public URL must persist for the retention period, an ended passport keeps its slug — it just reports the end-of-life status. Lineage links let a scanner follow a repurposed battery to its current passport.
Frequently asked
Does a repurposed battery keep its old passport?
No. Repurposing creates a new battery, so it gets a new passport with its own identifier, linked to the original passport for traceability.
What happens to the passport when a battery is recycled?
The passport reaches end of life and its public page reports that the battery no longer exists, while the URL itself is preserved for the retention period.
