Design and Development of a Wireless Mobile Charging System

This paper presents the framework and principle of mobile phone wireless charging system, and designs the mobile phone wireless charging system by using GPMQ8005B and BQ51013B. The coupling coils at the transmitter and receiver are designed. The importance of transmitting coil and receiving coil in the system is clarified in the design and development. Finally, it is concluded that the larger the coil diameter, the higher the transmission efficiency of the system, the smaller the coil diameter, the lower the transmission efficiency of the system, the shorter the distance, the higher the transmission efficiency, the farther the distance, the lower the transmission efficiency, the more turns of the coil, and the higher the transmission efficiency of the system, which provides a certain data reference for further research.
