Title Smart Wireless Charger for Mobile Devices
Supervisor Akshay Kumar Rathore
Description One of the main limitation of wireless charging is the alignment of the charging coil and device battery. This often requires the user to manually place and align the charging coils in order to effectively charge the device. One solution to this problem is developing a smart wireless charging pad which automatically aligns the charging coil with the battery of any device which is placed on it. This would eliminate the trial and error and manual aspect of wireless chargers and would guarantee maximum power transmission every time. The charging pad would utilize two motors which would move the charging coil in the x-y plane of the charging surface to correctly align with the device battery. The motors would be controlled by a microcontroller which would receive the device location through sensors embedded in the charging pad. The charging pad would also interface with our app which would allow the user to manage and view the current charging cycle as well as provide information of which phones are being charged. Device can be further developed to accept multi device charging where two devices can be placed on the pad and the device with the lowest state of charge would be prioritized with the second device being automatically switched to when the first is charged.
