s201, detecting the current power supply of the vehicle power supply end in the process of supplying power to the vehicle charging end based on the transmitting coil of the vehicle power supply end and the receiving coil of the vehicle charging end.
The vehicle power supply end may be a device end for providing power to the shared electric vehicle, alternatively, the vehicle power supply end may be installed under the ground. As shown in fig. 3, the vehicle power supply terminal includes: the device comprises a first power supply circuit, a first controller, a receiver, a first acquisition circuit and a transmitting coil. The first power supply circuit is used for being matched with the transmitting coil to supply power for the vehicle charging end under the control of the first controller, the receiver is used for receiving feedback information (such as current electric quantity information and current charging power) sent by the vehicle charging end, and the first acquisition circuit is used for acquiring the current power supply of high-frequency alternating current transmitted to the transmitting coil.
The vehicle charging terminal may be a device terminal for receiving power transmitted from a vehicle power supply terminal, alternatively, the vehicle charging terminal may be installed inside the shared electric vehicle. The specific structure of the vehicle charging terminal will be described in detail in the following embodiments.

Alternatively, the transmitting coil of the vehicle power supply end is installed on the ground surface, and the vehicle charging end is installed at the bottom of the shared electric vehicle.
The current power supply may be a power of electric power provided by the vehicle power supply terminal to the vehicle charging terminal.
Optionally, in a process of supplying power to the vehicle charging end based on the transmitting coil of the vehicle power supply end and the receiving coil of the vehicle charging end, the first collecting circuit in the vehicle power supply end may collect the current power of the output power in real time.
As shown in the schematic diagram of the vehicle power supply end in fig. 3, when the first controller of the vehicle power supply end receives the charging command sent by the vehicle charging end through the receiver, the first power supply circuit is controlled to transmit power to the transmitting coil, that is, the power frequency alternating current input by the mains supply is converted into direct current through the first rectifying circuit (that is, the filtering circuit), then the power frequency current is converted into high frequency alternating current receivable by the shared electric vehicle through the inverter circuit, and the high frequency alternating current is sent to the receiving coil of the vehicle charging end through electromagnetic induction based on the transmitting coil of the vehicle power supply end, so that the receiving coil transmits the received power (that is, the high frequency alternating current) to the electric appliance of the vehicle charging end, and the power supply of the vehicle charging end is realized. In the process, the first acquisition circuit in the vehicle power supply end can acquire the current power of the high-frequency alternating current transmitted to the transmitting coil in real time and transmit the current power to the first controller.

Optionally, if the current power supply and/or the current charging power are/is higher than a preset power threshold, determining that the current moment meets a power adjustment condition, and the power adjustment strategy is to reduce the power supply; if the current electric quantity information is that charging is completed, determining that the current moment meets a power adjustment condition, and setting the power adjustment strategy to zero the power supply power.
Specifically, if the first controller obtains that at least one of the current power supply and the current charging power has a power value higher than the preset power threshold, the first controller proves that the current power supply is higher, the situation that the shared electric vehicle is overheated is easily caused, and the current power supply is required to be adjusted, so that it is determined that the current time meets the power adjustment condition, and a power adjustment strategy for reducing the power supply is generated.
If the first controller obtains the current electric quantity information to finish charging, the first controller proves that no more power is required to be provided for the shared electric vehicle, and can stop electrifying the shared electric vehicle, so that the current moment is determined to meet the power adjustment condition, and a power adjustment strategy for zeroing the power supply power is generated.
S204, adjusting the current power supply power for supplying power to the charging end of the vehicle through the transmitting coil based on the power adjustment strategy.
Optionally, if the determined power adjustment strategy is to reduce the power supply power, the first controller controls the first power supply circuit to reduce the current power supply power, and transmits the lower current power supply power to the vehicle charging end through the transmitting coil; if the determined power adjustment strategy is to zero the power supply power, the first controller controls the first power supply circuit to stop power transmission, and at the moment, the power supply to the charging end of the vehicle is not needed through the transmitting coil.
According to the wireless charging method for the vehicle, in the process of charging the shared electric vehicle, the power adjustment strategy is generated according to the current power supply of the vehicle power supply end, the current electric quantity information fed back by the vehicle charging end and the current charging power, and the current power supply is adjusted according to the adjustment strategy. The method can monitor the current power supply and the current change of the charging power of the shared electric vehicle in the charging process, and timely adjust the current power supply to prevent the situation that the temperature of the shared electric vehicle is high due to the fact that the current power supply is too high.
It should be noted that, in order to further ensure the safety of the shared electric vehicle and the surrounding environment thereof during the charging process of the shared electric vehicle, in this embodiment, a fire extinguishing device may be further disposed around the charging area of the shared electric vehicle, and optionally, if a fire alarm event is detected at the charging end of the vehicle, the fire extinguishing device is controlled to extinguish the fire at the charging end of the vehicle.
The fire extinguishing device can be composed of an alarm device and a water sprinkling device, the alarm device can be installed on a canopy upright post of a shared electric vehicle parking area, and the water sprinkling device can be installed below a canopy of the shared electric vehicle parking area.
Specifically, if the first controller obtains temperature information and smoke information of the shared electric vehicle and surrounding environment thereof at the current moment through temperature detection equipment and smoke detection equipment connected with the vehicle power supply end, when the temperature information exceeds a preset temperature threshold value and the existence of the smoke information is detected, a fire alarm event is proved to exist at the vehicle charging end, and therefore the first controller controls the fire extinguishing device to extinguish the fire at the vehicle charging end.
The advantage of setting like this is, can in time detect and obtain the sharing electric vehicle whether fire event to when sharing electric vehicle's fire event exists, can pass through extinguishing device fast and put out a fire the processing, further improved sharing electric vehicle's security in the charging process.

Another alternative implementation manner may be to obtain position information of the receiving coil sent by the charging end of the vehicle relative to the parking space of the vehicle. Specifically, the first controller of the vehicle power supply end receives position information of the receiving coil, which is sent by the vehicle charging end, relative to the parking space of the shared electric vehicle through the receiver. It should be noted that, how the vehicle power supply end determines the position information of the receiving coil relative to the parking space of the vehicle will be described in detail in the following embodiments.
