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 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.
