Abstract: In a WPT system, varying parameters, such as coupling coefficient, may cause the system to fall out of resonance and/or tuning. By monitoring one or more signals within a coil module of the WPT device, this detuning can be detected.

For example, coil circuits in the transmitting and/or receiving WPT devices can be configured to allow for adjusting of effective capacitance, effective inductance, load resistance, and/or load inductance. In addition, frequency can be modified to permit adjusting power transfer efficiency.

Abstract: A wireless power transfer system is disclosed that includes multiple levels of authentication and several different options for implementing theft prevention. The power station can perform a first authentication procedure to collect billing information of the device to receive power. If the first authentication succeeds, the power station then performs a second authentication procedure in which it sends one or more test power signals to the receiving device. The power station estimates the amount of power that should actually be received by the receiving device and compares the estimate to a reported value sent from the receiving device to ensure that the reported value is within an acceptable margin of the estimate value. If either authentication fails, the power station can take power theft prevention methods to prevent the receiving device from acquiring free power.
