Where a Tesla Model Y (4680 Structural) 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 3 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 47% of the pack qualifies for reuse and goes to Nagpur — Butibori Second-Life Works (1,242 km). Moderate — structural pack bonding limits module harvesting; cell-level grading required.
- 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 Tesla Model Y (4680 Structural) battery
The Tesla Model Y (4680 Structural) (2022) carries a 82 kWh NMC 811 Cylindrical 4680 pack with 3 modules at 355 V, weighing roughly 418 kg. Structural tabless format requiring specialised disassembly cells. High nickel yields offset elevated processing cost.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 94.2% | A — BESS ready | USD 4,607 |
| Year 4 | 89.9% | A — BESS ready | USD 4,425 |
| Year 6 | 85.6% | A — BESS ready | USD 4,162 |
| Year 8 | 81.3% | B — Second life | USD 3,674 |
| Year 10 | 77% | B — Second life | USD 3,281 |
What the chemistry means here
How it ages
Fade mechanisms mirror other NMC 811 cells. The tabless design lowers internal resistance and heat generation, which can slow resistance growth relative to older cylindrical formats.
Thermal behaviour
4680 cells carry the same high-nickel chemistry as 2170s but in a larger can with more energy per cell, so a single failing cell releases more heat. Structural packs also make it harder to isolate an individual failing cell during handling.
Handling NMC 811 (4680)
Collecting a Tesla Model Y (4680 Structural) pack
82 kWh, 3 modules, about 418 kg — this is how the Kalamassery, Kerala 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
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.
