Abstract
A method for wireless power transfer adapts to changing configuration of receivers, including changes in number of, location and/or orientiation of, magnetic coupling to, and load of circuits (e.g., battery charging circuits) of one or more receivers. The adaptation can be performed without interrupting optimal or near-optimal power transfer to the receivers, and can provide a measure of fairness among multiple receivers.
Claims2
-34. (canceled)
A method for wireless power transmission comprising:
- wirelessly transmitting power from a base station including a plurality of transmitting coils to a plurality of receivers including a corresponding plurality of receiver coils, the wireless transmission of power including adapting a plurality of driving signals for driving the transmitting coils according to a plurality of magnetic channel characteristics characterizing a plurality of magnetic channels between the transmitting coils and the receiver coils;
- and
- without interruption of the wireless transmission of power,
- inferring changes in the magnetic channels between the transmitting coils and the receiver coils, and
- updating the plurality of magnetic channel characteristics according to the inferred changes in the magnetic channels between the transmitting coils and the receiver coils.
