1. A vehicle comprising
a power receiver configured to generate electric power above a first threshold by using an electromagnetic wave, transmitted from a power transmitter enabled to shift a frequency of the electromagnetic wave, of a frequency within a power generation frequency band;
a charger configured to charge a battery installed in the vehicle by an electric power generated by the power receiver;
a heat generator configured to generate heat above a second threshold by using the electromagnetic wave, transmitted from the power transmitter, of a frequency within a heat generation frequency band;
a battery pack configured to accommodate the battery with the heat generator, and arranged at a space of the vehicle such that a coil of the power receiver faces a coil of the power transmitter; and
a controller configured to make the power transmitter shift a frequency of the electromagnetic wave in accordance with the temperature of the battery,
wherein the controller is configured to change the frequency among frequencies including:
a first frequency included in a first frequency band overlapping
the power generation frequency band in which an amount of generated electric power is maintained at the first threshold or higher with
the heat generation frequency band in which an amount of generated heat is maintained at the second threshold or higher
a second frequency included in a second frequency band overlapping
the power generation frequency band with a frequency band, in which an amount of heat generated by the heat generator is suppressed to be more than 0 and less than the second threshold, and
a third frequency included in a third frequency band overlapping
the heat generation frequency band with a frequency band, in which an amount of electric power generated by the power receiver is suppressed to be more than 0 and less than the first threshold.
