Abstract
A system for wireless power delivery, preferably including one or more power receivers and a power delivery device (or multiple power delivery devices). The power delivery device preferably includes a housing and a transmitter. Each power receiver preferably includes one or more receiver antennas and electrical loads. A method for wireless power delivery, preferably including determining transmitter-receiver proximity, determining transmission parameter values, and/or transmitting power based on the transmission parameter values.
Claims20
A method for wireless power transmission from transmitter comprising a plurality of transmission elements within an RF cavity, the plurality of transmission elements associated with a configuration parameter space, the method comprising:
- selecting a first configuration in the configuration parameter space;
- at the transmitter, controlling the plurality of transmission elements based on the first configuration, wherein, in response to being controlled based on the first configuration, the plurality of transmission elements generate a first excitation pattern associated with a cavity mode of the RF cavity;
- while generating the first excitation pattern, at a receiver within the RF cavity, determining first information associated with efficiency of power transmission to the receiver via the first excitation pattern;
- based on the first information, determining a value, at the first configuration, of an objective function, wherein the objective function is associated with the receiver;
- performing an optimum search, in the configuration parameter space, based on the first information and on the objective function, wherein performing the optimum search comprises, for each of a plurality of test configurations in the configuration parameter space, evaluating the objective function at the test configuration, wherein evaluating the objective function at the test configuration comprises:
- at the transmitter, configuring the plurality of transmission elements based on the test configuration;
- at the transmitter, wirelessly transmitting power while the plurality of transmission elements is configured based on the test configuration;
- at the receiver, receiving power while the plurality of transmission elements is configured based on the test configuration;
- based on the power received at the receiver while the plurality of transmission elements is configured based on the test configuration, determining a power reception metric;
- and
- based on the power reception metric, determining a value, at the test configuration, of the objective function.
