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 [1]
  • peak charge power = 200kW
• modules:
  • 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/kg_10s
• Volumetric power density, pack = W/litre_10s
• Estimated cost = $/kWh
• Cell to Pack mass ratio
  • module to pack mass ratio = %
• Cell to Pack volume ratio

Other key features:

• Safety
• BMS
  • The battery management system is also configured specifically for AMG. [1]
  • 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. [1]
• 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
• Durability
• Warranty
  • 250,000km or 10 years [1]
  • certificate also covers capacity loss
• Availability
• 4R’s
  • 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.
• Shipping
