First Claim
1. A power transmission and reception system comprising a power transmitter and a power receiver, wherein:
- (i) the power transmitter comprises;
a power transmission module configured to wireless-transmit power to the power receiver; and
a first wireless communication module configured to perform wireless communication with the power receiver;
(ii) the power receiver comprises;
a power reception module configured to receive the power transmitted from the power transmission module; and
a second wireless communication module configured to perform wireless communication with the first wireless communication module using the received power;
wherein the second wireless communication module is configured to perform wireless communication while the power reception module is receiving the power;
wherein the power reception module comprises;
a coil configured to receive an electric wave configured to transmit the power;
a power reception controller configured to convert the electric wave to a current; and
a charge keeping module configured to keep charges by the current;
wherein the power receiver further comprises;
a charge monitor configured to monitor an amount of charges kept in the charge keeping module; and
a controller configured to start the wireless communication by the second wireless communication module when the amount of charges kept in the charge keeping module becomes over a first threshold after power reception is started; and
wherein the controller is configured to stop the wireless communication by the second wireless communication module when the amount of charges kept in the charge keeping module becomes below a second threshold.
