Electric drive cooling system

Coolant flows through the electric drive motors on the front and rear axles. They are integrated in the coolant circuit for the electric

powertrain. The power electronics are also integrated into this coolant circuit. The coolant flowing in is first directed to the power

electronics to dissipate the high levels of heat at the power modules. The coolant then flows through the stator cooling jacket. On

the rear axle, the coolant is additionally routed through the 2-speed transmission unit, before it leaves the electric drive motor. On

the Audi e-tron GT, only G12evo coolant must be used.
