Where a BMW i4 eDrive40 pack goes from Ulsan, South Korea
- 1
Intake at Ulsan, South Korea
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 Yokohama, Kanagawa
Modules travel 935 km to Yokohama — Kanagawa Diagnostics Works for capacity, resistance and impedance testing across all 8 modules.
- 3
Second life at Gothenburg, Sweden
At 80% SOH about 47% of the pack qualifies for reuse and goes to Gothenburg — Nordic Second-Life Campus (8,121 km). Good — grade-A modules above 80% SOH qualify for commercial-scale BESS strings.
- 4
Refined at Ningde, Fujian
Remaining modules are shredded to black mass and refined at Ningde — Fujian Refining Base, 1,354 km away.

Inside the BMW i4 eDrive40 battery
The BMW i4 eDrive40 (2022) carries a 83.9 kWh NMC 811 Cylindrical 2170 pack with 8 modules at 398 V, weighing roughly 470 kg. High-nickel cylindrical cells with the strongest hydrometallurgical recovery credit per tonne of black mass.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 94.5% | A — BESS ready | USD 5,244 |
| Year 4 | 90.2% | A — BESS ready | USD 5,035 |
| Year 6 | 85.9% | A — BESS ready | USD 4,754 |
| Year 8 | 81.6% | B — Second life | USD 4,135 |
| Year 10 | 77.3% | B — Second life | USD 3,625 |
What the chemistry means here
How it ages
NMC 811 loses capacity through a mix of SEI growth, cathode surface reconstruction and micro-cracking of nickel-rich particles. Resistance climbs faster than in LFP, which matters as much as capacity for second-life duty.
Thermal behaviour
High-nickel NMC cathodes release oxygen as they decompose, so once runaway starts it is fast and energetic. Cylindrical 2170 cells vent through a designed rupture point, which helps, but cell-to-cell propagation inside a tightly packed module is the main hazard.
Handling NMC 811 (2170)
Collecting a BMW i4 eDrive40 pack
83.9 kWh, 8 modules, about 470 kg — this is how the Ulsan, South Korea 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.
