The invention discloses a wireless charging system adaptive to various two-wheeled electric vehicle batteries. The wireless charging system comprises a ground transmitting device, a vehicle-mounted receiving device, a current sampling circuit, a voltage sampling circuit, a power management chip, a receiving end MCU processor and a receiving end wireless communication module. According to the vehicle-mounted receiving device, when a receiving coil receives electric energy of a transmitting coil in a standby state, a power management chip receives the electric energy of the receiving coil, triggers the power management chip to work and drives a receiving end MCU processor to work, and a voltage sampling circuit collects the voltage of a vehicle-mounted battery in real time; the voltage of the vehicle-mounted battery is transmitted to the receiving end MCU processor, the receiving end MCU processor transmits the voltage information of the vehicle-mounted battery to the ground transmitting device through the receiving end wireless communication module, and the ground transmitting device automatically matches a charging characteristic curve of the corresponding vehicle-mounted battery according to the voltage and capacity information of the vehicle-mounted battery, and a corresponding charging mode is automatically selected.
