Abstract
Official abstract text for this publication.
A method and system for efficiency compliance in a wireless battery charging system includes a wireless power source that provides a wireless charging power signal to devices in proximity to the wireless power source. The devices have a receiving coil to receive electrical energy from the wireless charging power signal, and they communicate battery charging metrics to the wireless power source. The wireless power source uses the battery charging metrics to determine a predicted system efficiency to charge the devices over a period of time, and when the predicted efficiency is below an efficiency standard, the wireless power source undertakes an action to improve system efficiency.
