随着电子科技领域的快速发展，有线充电出现了一部分的局限性，开启了无线式

With the rapid development in the field of electronic technology, some limitations have emerged in wired charging, opening the door to wireless charging technology. It is a group of energy transmission systems that are transmitted in the form of wireless charging, with a small device size and good transmission effect. Compared with wired, its convenience and safety have been improved, and it is relatively stable when affected by special circumstances. At present, wireless charging technology has also been widely used. <br>This time, the wireless charging system was designed and controlled and observed with a smart car. In order to better realize wireless charging, we will use the principle of electromagnetic induction and AT89C51 microcontroller to control. The wireless charging smart car composed of the wireless charging receiver and the transmitter, super capacitor, timer, relay, buck-boost module, and LCD display module makes the circuit protected and the car's charging status can be seen intuitively. We transfer power to the wireless transmitter to generate a current between the coil inductions, thereby transferring energy from the transmitter to the receiver, and then storing the converted energy in the capacitor in the receiver. Use the single chip microcomputer to charge the car for 1 minute clock timing, and use the relay to control the switch. The buck-boost module provides power to the car motor after boosting, which can start the car. It is mainly used to control the output problem of the circuit and let the power supply in the capacitor be discharged as much as possible. Finally, we will use the single-chip microcomputer to control the LCD12864 to display the 1-minute countdown and capacitor charging.
