The Lithium Battery Charging Management System Based on Wireless Energy Transmission

This paper presents a Lithium battery wireless charging management system based on the electromagnetic resonance theory. The proposed system is mainly comprised of an energy emitting module and an energy receiving module. The hardware circuit of the system has been developed to accomplish its function. The novelty of the proposed system is that it can guarantee the the energy transmitting power with transmission frequency 2MHz via the efficient frequency tracking. In the range of 3-5 meters, the Lithium battery can be charged up to 500mA current with high receiving efficiency and less energy consumption with the aid of Micro-computer unit. PSPICE software has been used to perform the simulation experiments to testify the effectiveness of the designed circuit.
