Abstract

The invention provides a wireless charging system for an electric automobile, to solve the problems of electrical leakage and physical deterioration of charging plant. The wireless charging system comprises a sending end connected to an electric network and a receiving end disposed on the automobile, wherein the sending end comprises a wireless communication unit and a sending unit. The sending unit is formed by serially connecting a rectification filter circuit, a high frequency inverter circuit and a sending loop. The receiving end comprises a wireless communication unit and a receiving unit. The receiving unit is formed by serially connecting a receiving loop and a rectification filter circuit. In the manner of high-efficient wireless transmission, the wireless charging system for an electric automobile of the invention solves the problems of electrical leakage and physical deterioration of charging plant, so the charging mode of the automobile is simpler, faster and more reliable.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to charging technology. Background technique [0002] As a new energy vehicle, electric vehicles have the advantages of no pollution, and are more and more popular and valued by people. The current electric vehicles generally adopt the contact charging method. The charging contacts are exposed outside the car, which is easy to leak electricity and cause electric shock hazards. In addition, after repeated plugging and unplugging operations, the charging contacts are prone to loose contact due to mechanical wear and tear. Reliable transmission of electrical energy. Contents of the invention [0003] The purpose of the present invention is to propose a wireless charging system for electric vehicles to solve the problems of electric leakage and mechanical wear of charging equipment. [0004] The electric vehicle wireless charging system of the present invention...
