Where a Switch Mobility EiV 12 City Bus pack goes from Tuas, Singapore
- 1
Collected via Ulsan, South Korea
Whole packs enter the network at Ulsan — Korea Recovery Campus, 4,637 km away, where they are weighed and de-energised.
- 2
Module grading at Tuas, Singapore
All 24 modules are tested for capacity, DC resistance and impedance, then assigned grade A to D.
- 3
Second life at Zwickau, Saxony
At 80% SOH about 56% of the pack qualifies for reuse and goes to Zwickau — Saxony Second-Life Works (9,976 km). Excellent — long calendar life makes LFP the preferred feedstock for stationary BESS repurposing.
- 4
Refined at Ningde, Fujian
Remaining modules are shredded to black mass and refined at Ningde — Fujian Refining Base, 3,291 km away.

Inside the Switch Mobility EiV 12 City Bus battery
The Switch Mobility EiV 12 City Bus (2022) carries a 350 kWh LFP Prismatic (LiFePO4) pack with 24 modules at 640 V, weighing roughly 2590 kg. Cobalt-free prismatic chemistry dominant in Indian passenger EVs and commercial fleets. Low black mass value, exceptional second-life economics.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 96.4% | A — BESS ready | USD 18,397 |
| Year 4 | 93.3% | A — BESS ready | USD 17,818 |
| Year 6 | 90.2% | A — BESS ready | USD 17,239 |
| Year 8 | 87.1% | A — BESS ready | USD 16,660 |
| Year 10 | 84% | B — Second life | USD 14,356 |
What the chemistry means here
How it ages
LFP fades slowly and fairly linearly for most of its life. Capacity loss is driven mainly by lithium inventory being locked up in the SEI layer on the graphite anode, while the cathode structure stays largely intact.
Thermal behaviour
LFP's olivine cathode holds its oxygen tightly, so thermal runaway typically starts at higher temperatures than nickel-rich cells and releases noticeably less heat. It is not inert: a failing LFP cell still vents flammable electrolyte vapour and hydrogen, and large prismatic cans store a lot of energy in one place.
Handling LFP Prismatic
Collecting a Switch Mobility EiV 12 City Bus pack
350 kWh, 24 modules, about 2590 kg — this is how the Tuas, Singapore team plans the job.
Removal
Roof- or floor-mounted packs are lifted by crane or gantry with the OEM lifting frame, one string at a time.
Packaging
Packs travel as individual heavy crates on flatbed or curtain-side trailers with load restraint rated for the mass.
Consolidation
Bus packs are collected per depot and per retirement window, usually a full trailer per visit.
Before the truck arrives
- Confirm crane or gantry access and lifting frame availability
- Isolate each pack string and record its voltage
- Share pack-string serials against the bus fleet number
- Plan collection around depot operating hours
Tuas, Singapore site notes
- Regional shipments require import permits.
- Provide serial lists.
- Damaged packs need declaration.
- Fleet pickups can be arranged.
