Where a Tata Motors Starbus EV 12m pack goes from Kalamassery, Kerala
- 1
Collected via Zaheerabad, Telangana
Whole packs enter the network at Hyderabad — Zaheerabad Recovery Campus, 860 km away, where they are weighed and de-energised.
- 2
Module grading at Kalamassery, Kerala
All 20 modules are tested for capacity, DC resistance and impedance, then assigned grade A to D.
- 3
Second life at Butibori, Maharashtra
At 80% SOH about 56% of the pack qualifies for reuse and goes to Nagpur — Butibori Second-Life Works (1,242 km). Excellent — long calendar life makes LFP the preferred feedstock for stationary BESS repurposing.
- 4
Refined at Sriperumbudur, Tamil Nadu
Remaining modules are shredded to black mass and refined at Chennai — Sriperumbudur Recovery Campus, 510 km away.
| Stage | Facility | Distance |

Inside the Tata Motors Starbus EV 12m battery
The Tata Motors Starbus EV 12m (2021) carries a 250 kWh LFP Prismatic (LiFePO4) pack with 20 modules at 600 V, weighing roughly 1850 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 | 96.3% | A — BESS ready | USD 13,128 |
| Year 4 | 93.2% | A — BESS ready | USD 12,714 |
| Year 6 | 90.1% | A — BESS ready | USD 12,301 |
| Year 8 | 87% | A — BESS ready | USD 11,887 |
| Year 10 | 83.9% | B — Second life | USD 10,195 |
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 Tata Motors Starbus EV 12m pack
250 kWh, 20 modules, about 1850 kg — this is how the Kalamassery, Kerala 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
Kalamassery, Kerala site notes
- Heavy commercial packs are routed to larger sites with lifting equipment.
- Keep packs covered during loading, especially in the monsoon months.
- Send a serial list with every consignment.
- Declare any water ingress or swelling at booking so the pack is isolated on arrival.
