Thermal management for the future is a highly complex concept with promising new solutions. Audi has stepped up the pace of development in this area.
The technical field of thermal management extends beyond the aspect of battery cooling to encompass the entire vehicle.The compressor for the air conditioning system has an electric drive so that it can continue running even when the combustion engine is switched off./via/read more: audi-technology-portal
The design of the heat pump is based on the classical refrigerant circuit, supplemented by an additional condenser, among other things. In the condenser the refrigerant compressed to high pressure and temperature levels is cooled, condensed and super-cooled.

Following expansion the coolant absorbs the heat from the surroundings in the other condenser, which acts as an evaporator.The heat pump is able to capture the waste heat from various components in the electric vehicle. In fast driving the electric motor(s), the battery and the power electronics together radiate about 5 to 15 kW of heat.
