Description

technical field

[0001] The invention relates to the technical field of wireless charging for electric vehicles, in particular to a control method for a wireless dynamic charging system for electric vehicles. Background technique

[0002] As problems such as global warming, air pollution, and the decline of petrochemical energy reserves become more and more serious, people begin to seek effective methods that can replace traditional cars and solve environmental pollution and other problems. As a new energy vehicle, electric vehicles have the advantages of low carbon, no pollution, environmental protection and cleanliness, and are an important development direction of new energy vehicles in the future. At present, electric vehicles have problems such as easy to cause battery pollution, poor battery life, and long single charging time. It takes a lot of time during the charging process, and there are certain safety hazards in the charging process.
