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.
Claims16
A device for transmitting wireless power, comprising:
- a primary coil array configured to send a ping signal according to one of a plurality of ping signal conditions, each of the plurality of ping signal conditions corresponding to a candidate charge distance;
- a detecting unit configured to detect a power receiver in relation to one or more primary coils of the primary coil array and determine a charge distance when a response message to the ping signal is received from the power receiver, wherein the charge distance comprises the candidate charge distance corresponding to the ping signal condition;
- a charge mode control unit for controlling a charge mode of the one or more primary coils based at least in part on a detection of the power receiver and the charge distance;
- and
- a communication and control unit configured to control power transfer via the one or more primary coils according to one or more control messages received from the power receiver.
