Abstract

Disclosed herein is a method of determining an operational configuration of a wireless power adapter. The method includes determining whether the wireless power adapter is calibrated to supply a legacy device with electrical energy. The method further includes, in response to determining that the wireless power adapter is not calibrated to supply the legacy device with electrical energy, delivering a first power signal to the legacy device via a first electrical coupling member. The method also includes detecting a response of the legacy device to receiving the first power signal, and based on the response of the legacy device, determining an operational configuration of the wireless power adapter. Furthermore, the method includes configuring the wireless power adapter to operate according to the determined operational configuration.

Dependent claims

A wireless power adapter comprising:

a first electric coupling member operable to couple to a power source;
a second electric coupling member operable to couple to a legacy device;
a wireless power receiver operable to receive electrical energy from a wireless power transmitter via a wireless resonant coupling link;
and
a controller configured to:
determine whether the wireless power adapter has access to preexisting calibration data for supplying the legacy device with electrical energy;
in response to the determination that the wireless power adapter does not have access to preexisting calibration data for supplying the legacy device with electrical energy, deliver a first power signal to the legacy device via the second electric coupling member, wherein the first power signal is received from the power source via the first electric coupling member;
receive information indicative of a response of the legacy device to receiving the first power signal, wherein the detected response is indicative of at least one of:
a voltage response, a current response, and a load impedance;
based on the received information, identify a type of the legacy device;
based on a power characteristic associated with the identified type of the legacy device, determine an operational configuration of the wireless power adapter;
and
configure the wireless power adapter to provide power to the legacy device according to the determined operational configuration.
