From Yokohama, Kanagawa
Where a Tata Curvv EV pack goes from Yokohama, Kanagawa
- 1
Collected via Ulsan, South Korea
Whole packs enter the network at Ulsan — Korea Recovery Campus, 935 km away, where they are weighed and de-energised.
- 2
Module grading at Yokohama, Kanagawa
All 16 modules are tested for capacity, DC resistance and impedance, then assigned grade A to D.
- 3
Second life at Gothenburg, Sweden
At 80% SOH about 56% of the pack qualifies for reuse and goes to Gothenburg — Nordic Second-Life Campus (8,567 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, 2,142 km away.
| Stage | Facility | Distance |
|---|---|---|
| Nearest intake yard | Ulsan — Korea Recovery Campus | 935 km |
| Nearest second-life works | Gothenburg — Nordic Second-Life Campus | 8,567 km |
| Nearest refinery | Ningde — Fujian Refining Base | 2,142 km |

Inside the Tata Curvv EV battery
The Tata Curvv EV (2024) carries a 55 kWh LFP Prismatic (LiFePO4) pack with 16 modules at 360 V, weighing roughly 407 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 | 95.4% | A — BESS ready | USD 2,862 |
| Year 4 | 92.3% | A — BESS ready | USD 2,771 |
| Year 6 | 89.2% | A — BESS ready | USD 2,680 |
| Year 8 | 86.1% | A — BESS ready | USD 2,538 |
| Year 10 | 83% | B — Second life | USD 2,127 |
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 Curvv EV pack
55 kWh, 16 modules, about 407 kg — this is how the Yokohama, Kanagawa team plans the job.
Removal
Packs are dropped on a vehicle lift using the OEM procedure and a rated battery table, then isolated at the service disconnect.
Packaging
One pack per UN-rated pallet box, strapped and restrained, with terminals capped and coolant ports sealed.
Consolidation
Dealer and workshop returns are consolidated into full truckloads, typically eight or more packs per run.
Before the truck arrives
- Pull the service disconnect and record pack voltage
- Drain or cap coolant lines before lifting
- Photograph the pack casing and any impact damage
- Keep the VIN and pack serial together on the manifest
Yokohama, Kanagawa site notes
- Provide serial lists and vehicle information.
- Engineering packs need architecture details.
- Damaged packs require declaration.
- Port-linked shipments need documents in advance.
