During the driving process, the powered car can detect its own remaining first remaining power. When the first remaining power of the powered car is lower than the first preset threshold, it means that the power of the powered car may be insufficient. In this case Next, the powered car may send a charging request to the charging car, and the charging request includes the first remaining power and the predetermined route of the powered car. For example, the powered car can send the charging request to all surrounding new energy cars through wireless communication.

S12. The charging car receives a charging request sent by the powered car, where the charging request includes the first remaining power of the powered car and the predetermined route of the powered car.

S13. The charged car detects the third remaining power of the charged car, and when the third remaining power is higher than a second preset threshold, judges the predetermined route of the powered car and the predetermined route of the charged car Whether there are overlapping routes between them, when the overlapping routes are greater than a preset length, a permission message is sent to the powered car, and the permission message includes at least one of charging speed, charging time, and magnetic field strength.

The charging vehicle detects its own remaining third remaining power, and when the third remaining power is higher than the second preset threshold, it indicates that the charging vehicle itself has sufficient power and can provide power to the powered vehicle.

The charging car determines whether there is an overlapping route between the scheduled route of the powered car and the scheduled route of the charging car. When the overlapping route is less than the preset length, it means that the charging car and the powered car cannot be in a long time. Keep driving at a short distance, unable to maintain the short distance mode required for wireless charging within a certain period of time, and does not meet the wireless charging conditions. When the overlapped route is greater than the preset length, it means that the charging car and the powered car can keep close distances along the overlapping route, and the wireless charging to the powered car can be completed during the short distance driving. During the wireless charging process, The distance between the two vehicles is based on the distance that can be wirelessly charged, for example, 5 meters or 2 meters.

For example, two coils with a certain fixed oscillation frequency, when a coil uses this frequency as a carrier wave to send the signal to be sent to the coil, the modulation signal becomes a sinusoidal baud after passing through the inductance and capacitance. The sexual signal is sent wirelessly, and another coil in the magnetic field will get the same signal with sine wave characteristics. This method can realize the transmission of electrical signals in a certain magnetic field.

The electric vehicle arrives at the confluence position and merges with the charging vehicle dispatched by the charging station, and the wireless power receiving module in the electric vehicle establishes a matching relationship with the wireless power supply module in the charging vehicle;

When the distance between the powered car and the charging car is kept outside the preset interval range, the powered car sends a heartbeat message to the charging car at predetermined time intervals to maintain the wireless power receiving The matching relationship between the module and the wireless power supply module, and when the distance between the powered car and the charging car is kept within the preset distance range, the powered car turns on the power receiving state and passes The built-in wireless power receiving module receives the power provided by the charging car through the wireless power supply module provided in the charging car, the wireless power receiving module is provided with a first coil, and the wireless power supply module is provided with a second coil. The first coil and the second coil have the same resonant frequency, so as to realize the resonance of the first coil and the second coil, and the charging vehicle receives power from the driving while driving. Wireless charging of cars;

Detecting the third remaining power of the powered car, and when the third remaining power of the powered car is higher than a third preset threshold, terminating the power receiving state, and sending a termination notice to the charging car;

Calculating the charging power according to the first remaining power and the third remaining power, and calculating the power charge based on the charging power and a preset unit price of power;

The charged car receives the termination notice, searches for the position of the second charging station closest to the current position of the charged car, and sends a parking request to the second charging station;

The second charging station receives the parking request, obtains information about the idle charging piles in the second charging station, allocates parking charging piles for the charging car in the idle charging piles, and sends a parking permit to the charging car , The parking permit includes the location of the parking charging pile;

The charging car forwards the parking permit to the power receiving car, and the power receiving car calculates the distance between the first charging station and the second charging station, and calculates the distance between the first charging station and the State the distance between the second charging stations and calculate the mileage fee;

The powered vehicle calculates a payment fee based on the electricity fee and the mileage fee, and the payment fee is the sum of the electricity fee and the mileage fee;

Sending, by the powered car, a payment message to the charging car, the payment message including the payment fee;

The charging car receives the payment message, and arrives at the parked charging pile according to the position of the parked charging pile included in the parking permit to replenish power.
The method for interactive wireless charging of a new energy vehicle during driving according to claim 1, wherein the method of sending a charging request to the first charging station closest to the current position of the charging vehicle includes wireless fidelity WI-FI or Bluetooth.
The method for interactive wireless charging of a new energy vehicle during driving according to claim 1, characterized in that, after the powered vehicle is turned on, the method further comprises:

Detecting, by the charging car, the fourth remaining power of the charging car, and when the fourth remaining power is lower than a fourth preset threshold, sending a notification to the powered car to terminate the power receiving state;

Calculating the charging power according to the second remaining power and the fourth remaining power;

Calculate the charging fee according to the charging power and the preset charging unit price;

Sending a charging message to the powered car, the charging message including the charging fee.
The method for interactive wireless charging of a new energy vehicle during driving according to claim 1, wherein the powered vehicle sends a payment message to the charging vehicle, and the payment message includes the payment fee, and The fee payment methods are prepaid account deduction, bank card account deduction, mobile payment account deduction, and application payment account deduction.
The method for interactive wireless charging during the driving of a new energy vehicle according to claim 4, wherein the fee payment method is WeChat payment or Alipay payment.
