Automated load tracking and system tuning mechanism for wireless charging
First Claim
1. A method of supplying power to a plurality of loads comprising:
- using a power supply to provide power to an active energy transfer coil where the frequency of the power being supplied to the active energy transfer coil is at an optimal operating frequency of the active energy transfer coil;
using a plurality of passive energy transfer coils that are each magnetically coupled to the active energy transfer coil to provide power to a plurality of loads;
using at least one sensor to monitor the plurality of loads by monitoring received power for each load and maximum allowed charging power for each load; and
using a computer system that includes control electronics to dynamically change the frequency of the power being supplied by the power supply to the active energy transfer coil to match an optimal operating frequency of a system that includes the power supply, the active energy transfer coil, the passive energy transfer coils and the plurality of loads.

Abstract
A system includes at least one active energy transfer coil and a first passive energy transfer coil. The active energy transfer coil is configured to couple with a power supply. The at least one active energy transfer coil has an active coupling range. The first passive energy transfer coil is magnetically coupled to the active energy transfer coil and is located within the active coupling range. The first passive energy transfer coil has a passive coupling range. The first passive energy transfer coil is configured to provide energy to a first device located within the passive coupling range and based on energy received from the at least one active energy transfer coil.
