Swapping
Battery Passport for Swapping Networks & Interoperable Stations
Battery swapping networks — two-wheeler swap stations, commercial fleet depots, emerging auto-swap pilots — depend on unique battery identifiers that persist across dozens of install/remove cycles. The EU passport and India's swapping policy both converge on UID-centric traceability.
Swapping-Specific Challenges
- Same physical battery scanned at multiple stations daily
- SoH must update without re-printing QR labels
- Ownership may transfer between operator and user across swap cycles
- Interoperability requires standardized UID format across network partners
Passport Data Across Swap Cycles
| Event | Passport update |
|---|---|
| Manufacturing | UID assigned, baseline SoH, QR applied |
| Station intake | Scan verifies identity; SoH read from BMS |
| Swap to user | Cycle count increment (backend API) |
| Return to station | SoH refresh, grading for redeployment |
| Retirement | Recycler access enabled |
Build the Network Foundation Now
Swap network operators launching in EU or India should deploy passport infrastructure before station count scales — retrofitting UID registries across 10,000 deployed batteries is exponentially harder than issuing passports at manufacturing.
PassCell API supports SoH updates and lifecycle events without QR reprinting — essential for swapping economics.
