1. A power supply method executed between a power transmitting device able to transmit power by emitting electromagnetic waves, and a power receiving device able to receive power supplied by the power transmitting device, the power supply method comprising the steps of:

  • evaluating the response delay time for communication via the communication link between the power transmitting device and the power receiving device;

    calculating the maximum value for the emitted output of electromagnetic waves meeting exposure standards on the basis of the response delay time;

    and causing the power transmitting unit to transmit power via a power supply link with the power receiving device at an output not exceeding the maximum value;

    the power supply method further comprising the steps of;

    detecting an anomaly in the power supply link on the basis of communication with the power receiving device via the communication link; and

    causing the power supply device to limit the output of the power supply link on the basis of the detection of an anomaly in the power supply link.
