POWER TRANSMITTING DEVICE, POWER RECEIVING DEVICE, POWER SUPPLY SYSTEM, AND POWER SUPPLY METHOD
First Claim
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.

Abstract
Provided are a power transmitting device, a power receiving device, a power supply system, and a power supply method able to supply electric power by emitting electromagnetic waves. A power transmitting device comprises: a calculating unit for calculating the maximum value for the emitted output of electromagnetic waves meeting exposure standards on the basis of a response delay time measured by the communication link between the power transmitting device and a power receiving device; a power transmitting unit for transmitting power via a power supply link with the power receiving device at an output not exceeding the maximum value; an anomaly detecting unit for detecting an anomaly in the power supply link on the basis of communication with the power receiving device via the communication link; and an output control unit for controlling the output on the basis of the detection of an anomaly in the power supply link.
