Abstract
A system for wireless power delivery including one or more transmitters and receivers. A method for wireless power delivery, preferably including: determining transmitter-receiver proximity; determining transmission parameter values, preferably including determining initial parameter values, evaluating candidate transmission parameter values, performing one or more local optimum searches, and/or performing one or more global optimum searches; and transmitting power based on the transmission parameter values.
Claims20
A system for wireless power transmission, comprising:
- a power transmitter comprising a plurality of transmission elements and a wireless communication receiver;
- and
- a power receiver comprising a power measurement element and a wireless communication transmitter;
- wherein:
- the system is configured to perform a local optimum search based on an objective function associated with the receiver, wherein, for each of a plurality of test configurations, the system evaluates the objective function at the test configuration, wherein:
- the power transmitter configures the plurality of transmission elements based on the test configuration;
- the power transmitter wirelessly transmits power while the plurality of transmission elements is configured based on the test configuration;
- the power receiver receives power while the plurality of transmission elements is configured based on the test configuration;
- based on the power received at the power receiver while the plurality of transmission elements is configured based on the test configuration, the power measurement element determines a power reception metric;
- the power receiver transmits the power reception metric to the wireless communication receiver via the wireless communication transmitter;
- the power transmitter receives the power reception metric via the wireless communication receiver;
- and
- the system determines a value of the objective function based on the power reception metric;
- the system is configured to select a selected configuration from the plurality of test configurations based on the local optimum search;
- and
- the power transmitter is configured to, in response to the system selecting the selected configuration:
- configure the plurality of transmission elements based on the selected configuration;
- and
- wirelessly transmit power to the power receiver while the plurality of transmission elements is configured based on the selected configuration.
