At this stage because of the quality of charging equipment, because of its convenience, safety, energy saving and the impact on the special environment, the continuous improvement of electricity transmission and transmission, the provision of electricity has been unable to meet the daily needs.

In order to better realize wireless charging we will use the principle of electromagnetic induction learned, wireless charging trolley has several parts, timing relay module and LCD display module by our microcontroller control, receiving power supply will be received power storage into the capacitor, by the lifting pressure module to control and protect the circuit input and output problems, electric drive device for verification experiments. We use the receiving end of the wireless charging module, by receiving the voltage sent from the DC regulated power supply into the transmitter of the wireless charging module, and then the electromagnetic emission, and then the receiving power converted is stored in the capacitor. The clock is timed through the AT89C51 microcontroller, and when the charging time reaches 1 minute, the microcontroller AT89C51 controls the power from the transmitter. When a relay controlled by the microcontroller is found to be low, it immediately controls the conditions under which the lift chip enables to switch. At this point, let the capacitor as drained into the power supply as possible, after the boost to provide electricity to the trolley motor, so that the car can start.

At this stage, because of the quality of charging equipment, its convenience, safety, energy saving and impact on the special environment, the continuous improvement of power transmission and transmission, the power supply can no longer meet the daily needs.

The electric drive device is used for verification Experiment. We use the receiving end of the wireless charging module to receive the voltage sent from the DC stabilized power supply into the transmitting end of the wireless charging module, then send out the electromagnetic, and then receive the converted power stored in the capacitor. Through the clock timing of AT89C51 microcontroller, and when the charging time reaches 1 minute, the microcontroller AT89C51 controls the power supply of the relay from the transmitter. When the relay controlled by the single-chip microcomputer finds low level, it immediately controls the condition that the voltage regulator chip enables switching. At this time, let the capacitor discharge into the power supply as much as possible, and provide power to the trolley motor after boosting, so as to start the trolley.<br>
