Method and apparatus for controlling wireless power transmission

摘要

Provided are a wireless power transmission control method and wireless power transmission control apparatuses. The wireless power transmission control method may include transmitting a wake-up request signal used to wake up a target device, and receiving a response message from the target device activated by the wake-up request signal. A source device may set a demand power based on the response message, and may transmit a resonance power to the target device based on the demand power.

主权项

1. A wireless power transmission control method, comprising:
transmitting a wake-up request signal that is used to wake up a target device; receiving a response message comprising an identification (ID) of the target device and information about an amount of power to be used by the target device from the target device that is activated by the wake-up request signal; setting a demand power based on the response message; transmitting a resonance power to the target device based on the set demand power; receiving at least one check message including a power receiving state of the target device in real-time; and adjusting the resonance power based on the check message.
