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.
