[0040] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0041] After the mobile phone scans the QR code on the display screen 43 or uses voice commands to select the car model, car license plate, charging time and other options, the car is circled, and the camera 42 scans the car that needs to be charged.
