Where a Tesla Model Y (4680 Structural) pack goes from Changsari, Assam
- 1
Intake at Changsari, Assam
One pack per UN-rated pallet box, strapped and restrained, with terminals capped and coolant ports sealed. Each pack is weighed, photographed and discharged below 30% state of charge.
- 2
Graded at Gurugram, Haryana
Modules travel 1,463 km to NCR — Gurugram Collection & Grading Hub for capacity, resistance and impedance testing across all 3 modules.
- 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 (1,425 km). Moderate — structural pack bonding limits module harvesting; cell-level grading required.
- 4
Refined at Haldia, West Bengal
Remaining modules are shredded to black mass and refined at Kolkata — Haldia Refining Works, 592 km away.
| Stage | Facility | Distance |
|---|---|---|
| Nearest grading bench | NCR — Gurugram Collection & Grading Hub | 1,463 km |
| Nearest second-life works | Nagpur — Butibori Second-Life Works | 1,425 km |
| Nearest refinery | Kolkata — Haldia Refining Works | 592 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 Changsari, Assam 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
Changsari, Assam site notes
- Onward transit takes longer than elsewhere because of distance and terrain.
- Batteries are held in monitored storage until a full load is assembled.
- Keep batteries protected from rain and humidity before collection.
- Declare any damage in advance so isolated storage is available.
