[0018] Initialize each wireless charging section, and set the number of vehicles that can be charged in each wireless charging section according to the wireless charging section information;

[0019] Monitor the number of vehicles on the wireless charging section, where the number of vehicles is the total number of vehicles being charged and vehicles being pre-charged;

[0020] When the number of vehicles on the wireless charging section reaches the number of vehicles that can be charged, the wireless charging section is judged to be unavailable and the status is marked in the charging road network diagram.

[0021] Furthermore, the evaluation of the vehicle accessibility is specifically as follows: based on the vehicle charging request information and the wireless charging section information, all wireless charging sections that the vehicle can reach when the battery energy is at the lowest point are calculated, and marked in the charging road network map.

[0022] Furthermore, after step 6, the step also includes recording, analyzing and detecting abnormalities of the data of the charging process to ensure the safety and continuity of the charging process.

[0023] The beneficial effects of the present invention are as follows: the present invention realizes the improvement of charging efficiency during driving of new energy vehicles through the combination of V2X communication technology and highway wireless charging technology, thereby enhancing safety during driving, improving user experience, reducing operating costs, and promoting the popularization of new energy vehicles and technological innovation.
