Where a BYD e6 Fleet 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 1 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 |
|---|---|---|
| Nearest intake yard | Hyderabad — Zaheerabad Recovery Campus | 860 km |
| Nearest second-life works | Nagpur — Butibori Second-Life Works | 1,242 km |
| Nearest refinery | Chennai — Sriperumbudur Recovery Campus | 510 km |

Inside the BYD e6 Fleet battery
The BYD e6 Fleet (2021) carries a 71.7 kWh LFP Prismatic (LiFePO4) pack with 1 modules at 400 V, weighing roughly 531 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 | 95.7% | A — BESS ready | USD 3,742 |
| Year 4 | 92.6% | A — BESS ready | USD 3,623 |
| Year 6 | 89.5% | A — BESS ready | USD 3,505 |
| Year 8 | 86.4% | A — BESS ready | USD 3,363 |
| Year 10 | 83.3% | B — Second life | USD 2,823 |
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 BYD e6 Fleet pack
71.7 kWh, 1 modules, about 531 kg — this is how the Kalamassery, Kerala team plans the job.

Removal
Large packs are removed at the depot with a forklift-rated battery table and the vehicle isolated under lock-out tag-out.
Packaging
Each pack travels in a rated crate or on a restrained pallet, with coolant drained and ports sealed.
Consolidation
Depot retirements are batched against the fleet replacement schedule so collections line up with vehicle swaps.
Before the truck arrives
- Share telematics SOH history if it is available
- Confirm forklift access and dock height at the depot
- Isolate high-voltage systems under lock-out tag-out
- Declare any pack involved in a collision
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.
