Wireless power transfer and receive method, apparatus and system
First Claim
1. A wireless power transmitter for transferring power to a wireless power receiver in a wireless manner, the wireless power transmitter comprising:
- a power transmission control unit configured to detect the wireless power receiver; and
a power conversion unit configured to transfer the power to the wireless power receiver;
wherein the wireless power transmitter is configured to;
receive at least one of an identification packet or a configuration packet transmitted in a first mode from the wireless power receiver;
determine, based on the configuration packet, whether or not the wireless power receiver supports a second mode different from the first mode; and
communicate with the wireless power receiver in at least one of the first mode or the second mode when the wireless power receiver supports the second mode,wherein the first mode is used for communication between one wireless power transmitter and one wireless power receiver, and the second mode is used for communication between one wireless power transmitter and a plurality of wireless power receivers, andwherein the configuration packet comprises operation mode information indicating a communication execution mode supported by the wireless power receiver.
