System and a method for charging multiple power receivers in a wireless charging environment
First Claim
1. A method for charging at least one device by a power transmitter in a wireless charging environment, the method comprising:
- broadcasting a discovery request;
determining whether a discovery response is received in response to the discovery request from at least one device within a wait time;
retransmitting the discovery request if the discovery response is not received from the at least one device within the wait time;
transmitting, to the at least one device transmitting the discovery response, confirmation information if the discovery response is received from the at least one device within the wait time; and
transmitting electromagnetic radiation to charge the at least one device if the discovery response is received from the at least one device within the wait time and an acknowledgment is received from the at least one device in response to the confirmation information,wherein the wait time is configured to be less than a threshold response time, andwherein the retransmitting of the discovery request is stopped after a predetermined number of times.

Abstract
A wireless power charging system and a method thereof are provided. The system includes a power transmitter configured to charge one or more power receivers. The power transmitter includes a signal and control unit configured to detect the one or more power receivers present within a radio frequency range of a power transmitter, transmit a request for discovering each of the one or more power receivers, and determine whether a response is received from each of the one or more power receivers. The power transmitter further includes a regulator unit connected to the signal and control unit configured to modulate an amount of radiation to be transmitted based on the number of power receivers that provided a response and a power conversion unit connected to the regulator unit transmitting energy radiation to charge the one or more power receivers.

6. A power transmitter for charging at least one device in a wireless charging environment, the power transmitter comprising:
-
a transceiver configured to broadcast a discovery request; and a control unit configured to; determine whether a discovery response is received from at least one device in response to the discovery request within a wait time, control the transceiver to retransmit the discovery request if the discovery response is not received from the at least one device within the wait time, control the transceiver to transmit, to the at least one device transmitting the discovery response, confirmation information if the discovery response is received from the at least one device within the wait time, and control the transceiver to transmit electromagnetic radiation to charge the at least one device if the discovery response is received from the at least one device within the wait time and an acknowledgment is received from the at least one device in response to the confirmation information, wherein the wait time is configured to be less than a threshold response time, and wherein the retransmitting of the discovery request is stopped after a predetermined number of times. - View Dependent Claims (7, 8, 9, 10)
