一种无线充电小车的设计

无线充电电动小车由单片机计时模块、无线充放电模块、电容充放电模块、升降压模块、自启动模块组成。直流稳压电源的5V电压通过无线充电模块的发射端发射出去,继而由无线充电模块的接收端接收,后将接收到的电能存储于超级电容中。通过AT89S52单片机时钟给充电小车计时,当计时充电时间达1min时,AT89S52单片机控制继电器切断发射端的电源。当小车自启动模块检测到低电平信号时,会立即控制TPS63020芯片的使能端,使TPS63020升降压模块处于工作状态,此时超级电容放电并经TPS63020升压后给小车电机供电,小车即能够自动行驶。

Wireless charging electric car by the single-chip microcomputer timing module,wireless charge and discharge module,capacitor Charge and discharge module,lifting pressure module,the self-starting module.The 5V voltage of the DC regulated power supply is emitted by the transmitting end of the wireless charging module,which is then received by the receiving end of the wireless charging module,and the received energy is stored in the supercapacitor.Through the AT89S52 single-chip microcomputer clock to the charging trolley timing,when the timing of charging time of up to 1 minutes,at89s52 single-chip microcomputer control relay cut off the transmitter end of the power.When the car self-starting module detected low-level signal,will immediately control the TPS63020 chip to enable the end,so that the TPS63020 pressure module in the working state,when the super-capacitor discharge and after the TPS63020 boost to the car motor power,the car can automatically travel.
