1. A thermal control system for an electric vehicle comprising:
a high voltage battery;
a first heat exchanger adapted to be in contact with ambient air for circulating a heat exchange medium in thermal contact with the ambient air;
a second heat exchanger in thermal contact with the high voltage battery;
a heat transport system for transporting the heat exchange medium from the first heat exchanger to an evaporator/condenser assembly that is in thermal contact with the second heat exchanger for transfer of heat to the high voltage battery and for transporting the heat exchange medium back to the first heat exchanger; and
at least one of the first heat exchanger or the second heat exchanger being provided with a vibration device for releasing of ice formed on the at least one of the first heat exchanger or the second heat exchanger, the vibration device comprising an ultrasonic transducer that is placed on the at least one of the first heat exchanger or the second heat exchanger and that is adapted to generate sonic waves along an outer surface of the at least one of the first heat exchanger or the second heat exchanger, the outer surface forming an interface with an ice layer, for melting ice at the interface.
