From Stuttgart, Germany
Where a Olectra K9 Electric Bus pack goes from Stuttgart, Germany
- 1
Collected via Dubai, UAE
Whole packs enter the network at Dubai — Jebel Ali Logistics Yard, 4,759 km away, where they are weighed and de-energised.
- 2
Module grading at Stuttgart, Germany
All 22 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 (321 km). Excellent — long calendar life makes LFP the preferred feedstock for stationary BESS repurposing.
- 4
Refined at Lyon, France
Remaining modules are shredded to black mass and refined at Lyon — Auvergne-Rhone-Alpes Refinery, 469 km away.
| Stage | Facility | Distance |
|---|---|---|
| Nearest intake yard | Dubai — Jebel Ali Logistics Yard | 4,759 km |
| Nearest second-life works | Zwickau — Saxony Second-Life Works | 321 km |
| Nearest refinery | Lyon — Auvergne-Rhone-Alpes Refinery | 469 km |

Inside the Olectra K9 Electric Bus battery
The Olectra K9 Electric Bus (2021) carries a 324 kWh LFP Prismatic (LiFePO4) pack with 22 modules at 620 V, weighing roughly 2398 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 | 95.5% | A — BESS ready | USD 16,875 |
| Year 4 | 92.4% | A — BESS ready | USD 16,339 |
| Year 6 | 89.3% | A — BESS ready | USD 15,803 |
| Year 8 | 86.2% | A — BESS ready | USD 15,034 |
| Year 10 | 83.1% | B — Second life | USD 12,605 |
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 Olectra K9 Electric Bus pack
324 kWh, 22 modules, about 2398 kg — this is how the Stuttgart, Germany 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
Stuttgart, Germany site notes
- Engineering packs should come with architecture information.
- Suppliers can book recurring collections for returns.
- Damaged packs need ADR-compliant packaging.
- Send a serial list with each delivery.
