Abstract

Wireless charging provides a convenient way to charge various mobile and IoT devices. Prior work in state-of-theart wireless charging systems operates at a frequency controlled by explicit networking from the power-receiving devices and is designed for the environment when the participating devices are perfectly aligned with each other. The need for the finer control due to the devices' misalignment is increasing in near-field and pseudo-tightly coupled charging applications, as more charging pads, are being deployed in the public domains and serving heterogeneous clients. Because inductive-coupled charging applications are sensitive to the placement and alignment variations between the power-transmitting and the power-receiving coils, we design and build Cognitive Wireless Charger (CWC). CWC adaptively controls the operating frequency in real time using implicit feedback for optimal power transfer operations. This demo is to supplement our paper about CWC [1]. In this demo, we showcase the impact on power transfer performance caused by the variations in the placement and alignment between the charging coils of power transmitter and power receiver and demonstrate the performance improvement provided by CWC.
