Dynamic wireless charging system of electric car based on ultracapacitor

Abstract：This design takes the electric car wireless charging as the theme and realizes the electric car dynamic wireless charging system with the supercapacitor as the basic energy storage device.The system uses the mode of combining the wireless charging module with the ultracapacitor set.By converting the direct current into highfrequency alternating current,the ultracapacitor is charged wirelessly through the principle of electromagnetic induction.The experiment can realize the charging indicator light to light up when the car is charging at a certain point on the track.When the external power supply is cut off and the charging power is cut off,the car can start automatically and follow the track.Finally,it is proved that the combination device of ultracapacitor and wireless charging module can realize the car can flash charge when passing the electrified coil and continue to travel along the established running track.
