摘要： A power transmitter is provided herein. The power transmitter provides executing a dynamic heating operation with a heating object. The power transmitter senses a metallic structure in a presence of a coil of the power transmitter and transmits waves at one or more frequencies in response to sensing the metallic structure. The power transmitter determines that the metallic structure is the heating object based operation conditions respective to transmitting the waves and executes the dynamic heating operation by providing a power transfer to the heating object.

摘要： A power transmitter is provided herein. The power transmitter executes in-band communication with a power receiver. The power transmitter receives a reported voltage from the power receiver and dynamically determines a coupling between the power transmitter and the power receiver from the reported voltage. The power transmitter also dynamically determines an operating frequency for power transmission between the power transmitter and the power receiver.

摘要： A system is provided herein. The system includes modules of an electric vehicle and a power receiver of the electric vehicle. The power receiver includes receiving coils and a controller. Each of the receiving coils directly and separately connects to a separate one of the modules. The controller monitors currents to and from each of the modules and modifies operation points of each of the modules by changing frequency or duty cycle to achieve a target current.

摘要： A power transmitter may send a digital ping to a receiver. The power transmitter may transfer power to the receiver. The power transmitter may receive a report from the receiver which may comprise a received power value. The power transmitter may determine a transmitted power parameter value, which may be based on a threshold value subtracted from a transmitter power and based on transmitter losses subtracted from the transmitter power. The power transmitter may determine that the received power value is less than the determined transmitted power parameter value and may send an analog ping to the receiver in response to a determination that the received power value is less than the determined transmitted power parameter value. The power transmitter may measure a decay pattern of the analog ping. The power transmitter may determine that the receiver comprises a friendly foreign object. The power transmitter may update the threshold value.

摘要： A power receiver is provided herein. The power receiver provides in-band communication with a power transmitter. The power receiver recognizes a change in frequency that identifies a training sequence and determines an impulse response with respect to the training sequence. The power receiver also cancels an effect of the impulse response during the in-band communication.
