1. A method of controlling an inductive charging system comprising:
- providing an inductive primary power supply;
placing an inductive secondary device within the operating range of the primary power supply;
providing information from the power management unit of the secondary device to the primary power supply, wherein the information includes information regarding the future activation of a feature of the secondary device; and
controlling the primary power supply at least partially as a function of the information from the power management unit.

Abstract
A method of controlling an inductive charging system on those occasions in which the combined power requests of a plurality of secondary devices exceed the power capacity of the power supply. The method includes at least one of (a) powering each device at a level below its requested level, (b) powering each device sequentially, and/or (c) powering each device in a repetitive pattern (e.g. time multiplexing). Also disclosed is a method of controlling an inductive charging system at least partially as a function of information received from the power management unit (PMU) of each secondary device.

6. A method of controlling an inductive charging system comprising:
-
placing a plurality of inductive secondary devices within the operating range of an inductive primary power supply; determining the combined power requests of the secondary devices as a function of information regarding the future activation of features of the secondary devices; comparing the combined power requests of the secondary devices to the power capacity of the primary power supply; and if the combined power requests exceed the power capacity, then communicating to at least one secondary device that it will receive power at a reduced level from its power request. - View Dependent Claims (7, 8, 9, 10)

11. A wireless power supply for providing power wirelessly to a secondary device, the wireless power supply comprising:
-
a primary inductor for wirelessly transferring power to a secondary device; and a controller for controlling the transfer of wireless power to the secondary device, wherein the controller implements a control loop; and a power management interface that includes communication circuitry for receiving power management information, wherein the power management interface improves loop reaction time of the control loop based on the power management information received from the secondary device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
