The 2021 Mercedes-AMG EQS 53 4MATIC+
The performance luxury electric vehicle offering from Mercedes and part of the Mercedes EQ line up of EV’s.
- total energy = kWh
- usable energy = 107.8kWh
- Usable SoC = %
- peak discharge power = 544kW10s
Peak power is based on 490kW peak motor power published by Mercedes  and assuming 90% efficiency, thus 490kW / 0.9 = 544kW
The peak acceleration time for the vehicle and hence we assume battery peak power is only available above 75% SoC .
- continuous power kW
- peak regen power = 300kW
- nominal voltage = 396V
- capacity = Ah
- voltage range = V to V
- weight =kg
- cells = kg
- volume pack = litres
- pack dimensions =
- module =
- number of cells = 216
- make and model = CATL
- chemistry = NMC811 
- Format = prismatic
- Nominal voltage = 3.67V
- Nominal capacity = Ah
A flat rectangular pack design that has moved on a generation from the EQA battery. This battery design has 12 modules arranged in a single layer and in a rectangular aluminium pack structure.
- charge time = 10 to 80% in minutes
- 300km added to the range of the car in 19 minutes 
- peak charge power = 200kW
- 12 modules
- module configuration = 9s2p
- cooling system = liquid (water-glycol)
- The aluminium extrusions of the battery frame have defined cavities through which the coolant flows.
- pack cost =
Key Pack Metrics:
- Gravimetric energy density, pack = Wh/kg
- Cell = Wh/kg
- Volumetric energy density, pack = Wh/litre
- Gravimetric power density, pack = W/kg10s
- Volumetric power density, pack = W/litre10s
- Estimated cost = $/kWh
- Cell to Pack mass ratio
- module to pack mass ratio = %
- Cell to Pack volume ratio
Other key features:
- The battery management system is also configured specifically for AMG. 
- Safety includes: for example, temperature, voltage or insulation monitoring as a continuously monitoring safety system. If a fault occurs, the battery switches off.
- Crash monitoring when stationary (during DC charging) is also standard.
- HV Distribution
- One special technical feature is the AMG-specific wiring, which is adapted to the high performance capacity. 
- HV and LV Connections
- All connections to the battery are made at the rear of the pack on the bump in the top of the case that accommodates the HV control system.
- Cooling Connections
- Structure = non-structural pack
- The battery sits in a crash-protected area in the underbody, embedded in the body shell structure including an extruded aluminium profile on the side.
- The housing with energy absorbing structures at the front and side as well as a rigid, double-walled base plate provide additional protection for the modules.
- Case material
- Aluminium, aluminium extrusions.
- Sealing strategy
- Venting strategy
- 250,000km or 10 years 
- certificate also covers capacity loss
- After use in the vehicle, a second lease of life is possible for batteries: For example, in an energy bank operated by Mercedes-Benz Energy GmbH.
