2024 Audi Q6 e-tron quattro

The 2024 Audi Q6 SUV e-tron quattro has a 100kWh battery pack that uses large CATL prismatic cells.

A rectangular flat pack design.

The first of Audi’s production vehicles based on the Premium Platform Electric (PPE) architecture.

  • Energy Density = 169.5 Wh/kg
  • Power Density
    • Discharge = 534 W10s/kg
    • Charge = 458 W10s/kg
  • Usable Energy = 94.9 kWh (100 kWh total)
    • SoC Window = 94.9%
  • Nominal Voltage = 662 V
  • Nominal Capacity = 151.1 Ah
  • Configuration
    • = 180s 1p
    • Total number of cells = 180
  • Power
    • Peak system power = 315 kW10s
    • Regen Power = 220 kW10s
  • Warranty
    • 8 Years
    • 100,000 Miles
  • Pack Mass = 590 kg

The Audi video shows that the pack has a fire protection layer applied over the top of the modules.

In the next image you can see a significant number of fixing holes through the pack that are along the 2nd and 4th of the north-south battery beams.

This beam structure means the body supports the longitudinal (north-south) load paths for front and rear crash. The beams in the floor of the pack running transverse (east-west) support the side impact.

In reality, the breakdown of the load paths in a crash are complex and will not be as cleanly distributed as the image suggests.


The liquid cooling channels are external to the battery pack, a formed coolant panel is fixed and sealed to the underside of the lower battery pack plate. This means that all of the coolant connections are made outside the pack.

The upside of this design is any coolant leak will be outside and away from the HV system. The downside is the heating and cooling is applied to the battery pack as a whole. Hence some energy is lost to heating and cooling the pack enclosure. A lower cover made from plastic helps to reduce the losses to the atmosphere.


2024 Audi Q6 Battery fast charging
  • Charging = 270 kWfast
  • 10-80% SoC = 21 minutes

This peak charge power is on an 800V charger.

This post has been built based on the support and sponsorship from: Thermo Fisher ScientificEatron TechnologiesAbout:Energy and Quarto Technical Services.

The battery is capable of bank charging, splitting into two 400V units and then being charged from a 400V capable charger at 135kW. The same battery pack is used in the Porsche Macan EV and they state:

If necessary, the states of charge of the two battery halves are first aligned before they are charged together.

What we don’t know yet is how they are aligned and what SoC difference is acceptable. Our assumption is that this alignment is more likely to be required as the pack ages.


A quite standard module configuration with 15 prismatic cells all connected in series. Zoomed in you can see a layer of foam to allow for cell expansion.

  • Number Modules = 12
  • Cells/module = 15
  • Expansion foam between cells
  • CMC per module


  • Manufacturer = CATL
  • Format = Prismatic
  • Chemistry = NMC811
  • = Prismatic Format
  • Nominal Capacity = 151.1 Ah
  • Nominal Voltage = 3.68 V
  • Nominal Energy = 556 Wh

Cell data based on values given by Audi in their EPA application.
