Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
