Embodiment Construction
[0026] figure 1 The construction of a waste heat utilization system 1 according to the invention for an electric vehicle is shown by way of example in a schematic representation like a circuit diagram. The electric vehicle includes an electric motor 2 for driving the electric vehicle, and a battery 3 for supplying electric power to the electric motor 2 . The battery 3 is of rechargeable design so that it can be charged at a charging station (not shown) in a discharged state.
[0027] The waste heat utilization system comprises an air conditioning circuit 20 for air conditioning the vehicle interior 54 of the electric vehicle, for which purpose a working medium 21 circulates in the air conditioning circuit 20 during operation of the waste heat utilization system 1 . Arranged in the air conditioning circuit 20 are a compressor 22 for compressing the working medium 21 , a condenser 11 for condensing the working medium 21 and an evaporator 23 for evaporating the working medium 21...

The present invention relates to a waste heat utilization system for an electric vehicle, which includes an electric motor for driving the electric vehicle and a battery for supplying electric energy to the electric motor, and has an air-conditioning system for air conditioning the vehicle interior of the electric vehicle. A conditioned air-conditioning circuit, wherein the air-conditioning circuit is circulated with a working medium during operation of the waste heat utilization system, having a cooling circuit for cooling the electric motor and / or the battery, in the operation of the waste heat utilization system A coolant circulates in the cooling circuit during operation; there is a heating circuit in which a heating medium circulates, and a second conveying device and a second heat exchanger are arranged in the heating circuit, the A second conveying device is used to drive the heating medium, and the second heat exchanger is used to discharge heat from the heating medium into the vehicle interior of the electric vehicle.
Description
technical field [0001] The present invention relates to a waste heat utilization system for an electric vehicle, and to an electric vehicle having such a waste heat utilization system. Background technique [0002] In electric vehicles, ie in electrically driven vehicles, a rechargeable battery, which is present for driving the electric motor, is used to provide electrical energy for various auxiliary units, ie for electrical consumers. Since the waste heat generated by the internal combustion engine is not available in electric vehicles to heat the interior of the vehicle, an electrically operated heating device is required, which also draws the electrical power required for operation from the battery of the electric vehicle. However, electrical energy is no longer available to drive the electric motor, which can significantly reduce the range of electric vehicles. SUMMARY OF THE INVENTION [0003] The object of the present invention is therefore to create a waste heat u...
