A vehicle includes a thermal energy management system with first and second thermal fluid loops. The first thermal fluid loop includes a coolant pump configured to circulate a coolant through a vehicle battery and a chiller. The second thermal fluid loop is configured to circulate a refrigerant through the chiller, a compressor, and at least one condenser. The controller is configured to control the thermal energy management system according to a passenger compartment cooling mode and a battery cooling mode. In the passenger compartment cooling mode the compressor is operated at a first power setting. In the battery cooling mode the compressor is operated at a second power setting and the chiller is controlled to transfer thermal energy from the first thermal fluid loop to the second fluid thermal loop. The second power setting is less than the first power setting.

The invention relates to a method for defrosting an external-air heat exchanger of an electric vehicle. Contrary to the conventional principle of operating systems in an electric vehicle at the lowest possible output power, according to the invention, high output power is used for the defrosting process, to reduce the defrosting time and thus reduce heat loss.
