Abstract

The invention discloses a dynamic wireless charging load prediction control method for electric vehicles, and belongs to the technical field of electric vehicle wireless charging. The method includesutilizing an electric vehicle dynamic wireless charging system to perform prediction control on a receiving end load; taking the collected current and voltage of a load battery as the input signal ofa controller; and judging charging modes and switching the charging modes by estimating the charged state of the load battery, and converting an output signal into a duty cycle control DC/DC conversion module to realize power regulation. The electric vehicle dynamic wireless charging system can realize the reasonable distribution of system resources, so that the electric energy loss during the transmission of electric energy can be saved, magnetic flux leakage can be reduced, the transmission efficiency of the system can be enhanced, situations of overcharging can be decreased, the service life of vehicle batteries can be prolonged, and therefore, the stability of the dynamic charging of electric vehicles can be guaranteed, and safety and reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle wireless charging, in particular to a dynamic wireless charging load prediction control method 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. [0003] Electric vehicle wirel...
