摘　　要：以STC15单片机为核心设计了无线充电自启动小车,主要模块包括继电器控制、无线充电、断电自启动、DC-DC升降压等。根据电磁感应充电技术及超级电容储能特性,实现了小车的无线充电功能。实验表明:当无线充电线圈与接收线圈距离距离为1~3 mm时,充电效果达到最佳,小车行驶距离可达约18 m;当两线圈的距离为8 mm时,超级电容两端的电压为1.76 V.In this paper,a wireless charging self-starting car was designed with STC15 microcontroller as the core,which includes relay control module,wireless charging module,power off self-starting module,and DC-DC lifting voltage modules.With the adoption of electromagnetic induction charging technology and energy storage characteristics of supercapacitor,the wireless charging function of a car has been performed successfully.The experimental results show that the charging effect is the best when the distance between the two coils of wireless charging is 1~3mm,and the car can run to about 18m away.When the charging coil keeps 8mm away from the receiving coil,the voltage acvoss the supercapacitor is 1.76V.
