Abstract
A wireless power transmitting and charging system is disclosed. A method for operating a power transmitter of the wireless power transmitting and charging system comprises the steps of: maintaining a ping value table where ping signal conditions are mapped according to the height of a power receiver; recognizing the power receiver by varying a ping signal according to the ping signal conditions recorded in the ping value table; and controlling a charging mode according to a message received from the power receiver.
Claims17
A method for operating a wireless power transmitter, comprising:
- maintaining a ping value table having a plurality of ping signal conditions that are mapped to different frequencies of a ping signal;
- varying a ping signal condition of the ping signal according to the ping value table;
- detecting a power receiver based on the ping signal of a particular ping signal condition from among a plurality of ping signal conditions;
- and
- controlling power transfer based on a charge mode according to a message from the power receiver and an initial driving condition mapped to the particular ping signal condition, the particular ping signal condition having been set based on a previous ping signal condition that was successful in detecting the power receiver.
