Abstract: This paper aims at the safety problem of wireless charging for electric vehicles, a safe wireless charging system based on
magnetic coupling resonance is designed. The output terminal of the system monitors the battery voltage, current and battery temperature
in real time and feeds back to the input terminal. The battery terminal adopts the mainstream constant current constant voltage charging
mode during the charging period. The simulation based on Matlab/Simulink shows that the voltage and current waveform of the designed
