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 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.
