Development of an Automatic Bidirectional Wireless Charging System for Mobile Devices

Abstract

Bidirectional wireless charging technology is an emerging technology within the wireless power transfer (WPT) field of research. Bidirectional wireless power transfer (BWPT) allows the same device to not only receive power but also transmit power to other compatible devices. This paper documents the development of a prototype BWPT system for mobile devices which will allow for two mobile devices to share power wirelessly without the need for cables. In this device the data transfer capabilities of WPT will be utilized to ensure that minimal input is required from a potential user by automating the power transfer process as much as possible to make the system simple to use for any potential end-user. This feature will differentiate this design from other existing BWPT where this feature seems to be ignored or manual inputs from the user are required to configure the devices involved in BWPT.
