Such as wireless charger and it can provide energy to the cardiac pacemaker or a high speed rotation body. Wireless power transmission principle was found over a hundred years. Because of the scientific and technical reasons, it has not been applied. Factors that affect the application of wireless power transmission is low power transmission efficiency and the short transmission distance . This article designed a wireless charging system which based on electromagnetic resonant coupling. This charging is controlled by MCU. It is able to identify whether the system is no-load. When there is no-load, the charging will automatically cut off the power supply of the transmitter coil. 50% of the charging efficiency of this system can be achieved within a distance of 0.5 cm. The system is designed to charge the battery. Wireless charging devices and lithium batteries are installed in a smart car . The charging system can automatically identify low battery, then make arrangements for charging. The charging process is divided into three parts: pre-charging, constant current charging, constant voltage charging. This charging method to ensure that the battery is fully charged ,
