Project description

Wireless charging has become a growing industry in recent years. With manufacturers continuing to develop inductive charging and resonant charging technologies, this research seeks to assess the limits of inductive charging systems, and assess how fundamental physics may dictate these limits. Specifically, this work will examine how charging time varies with charger-appliance separation and compare it to the scaling of coil mutual inductance with the same separation. It is expected that the scaling of mutual inductance should cause the charging to be slower at greater separation (less power transferred). This research serves seeks to understand the technology of wireless charging protocols to serve as a basis for improvements for future wireless charging systems, particularly as technologies such as resonant charging start to become more commonplace.
