Where a Mercedes-Benz EQS 580 pack goes from Tuas, Singapore
- 1
Collected via Ulsan, South Korea
Whole packs enter the network at Ulsan — Korea Recovery Campus, 4,637 km away, where they are weighed and de-energised.
- 2
Module grading at Tuas, Singapore
All 12 modules are tested for capacity, DC resistance and impedance, then assigned grade A to D.
- 3
Second life at Zwickau, Saxony
At 80% SOH about 47% of the pack qualifies for reuse and goes to Zwickau — Saxony Second-Life Works (9,976 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, 3,291 km away.

Inside the Mercedes-Benz EQS 580 battery
The Mercedes-Benz EQS 580 (2022) carries a 107.8 kWh NMC 811 Cylindrical 2170 pack with 12 modules at 400 V, weighing roughly 604 kg. High-nickel cylindrical cells with the strongest hydrometallurgical recovery credit per tonne of black mass.
| Service year | SOH | Grade | Value |
|---|---|---|---|
| Year 2 | 95.7% | A — BESS ready | USD 6,812 |
| Year 4 | 91.4% | A — BESS ready | USD 6,544 |
| Year 6 | 87.1% | A — BESS ready | USD 6,276 |
| Year 8 | 82.8% | B — Second life | USD 5,521 |
| Year 10 | 78.5% | B — Second life | USD 4,826 |
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 Mercedes-Benz EQS 580 pack
107.8 kWh, 12 modules, about 604 kg — this is how the Tuas, Singapore 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.
