Dynamic wireless charging system of electric car based on ultracapacitor

以电动小车无线充电为主题,实现了以超级电容为基本储能装置的电动小车动态无线充电系统。该系统使用了将无线充电模块与超级电容组相结合的模式,通过把直流电转换成高频交流电,再通过电磁感应原理为超级电容无线充电,放电时通过Boost变换为小车提供电能。实验可实现小车在跑道上的某点充电时,充电指示灯点亮起;当外界电源切断,充电断电后,小车可自动启动并循迹行驶。最终证明了超级电容与无线充电模块组合装置可实现小车在行驶中,经过通电线圈时可以进行闪充,并沿着既定运行轨道继续行进。

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.
