Whole packs enter the network at Hyderabad — Zaheerabad Recovery Campus, 550 km away, where they are weighed and de-energised.
- 2
Module grading at Hosur, Tamil Nadu
All 24 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 (918 km). Excellent — long calendar life makes LFP the preferred feedstock for stationary BESS repurposing.
- 4
Refined at Sriperumbudur, Tamil Nadu

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 Hosur, Tamil Nadu 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

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
