Strong electromagnetic coupling wireless charging device for electric vehicle

Abstract

The invention relates to a strong electromagnetic coupling wireless charging device for an electric vehicle, which comprises a mains supply, a primary rectifier filter, a primary converter, a primary coil of a separable electromagnetic coupler, a movable original coil support, a secondary coil of the separable electromagnetic coupler, a magnetic concentrating iron core, a movable secondary coil support, a secondary rectifier filter, a charging controller, a storage battery and the electric vehicle. A power frequency alternating current is input into the primary rectifier filter; a stable direct current is output by the primary rectifier filter; the stable current is subjected to high frequency inversion into a high frequency alternate current through the primary rectifier filter; the high frequency alternate current is sent to the primary coil of the separable electromagnetic coupler; and the magnetic concentrating iron core is arranged in the primary coil of the separable electromagnetic coupler, the primary coil of the separable electromagnetic coupler can move up and down through the movable primary coil support and the secondary coil of the separable electromagnetic coupler can move up and down through the movable secondary coil support so as to generate strong electromagnetic coupling, thereby realizing high magnetic density energy transmission.

Description

Technical field: [0001] The invention relates to a car charger, in particular to a strong electromagnetic coupling wireless charging device for electric cars. Background technique: [0002] After the outbreak of the three global oil crises in the 1970s, various multinational automobile companies began to develop various types of electric vehicles. my country has also invested a lot of manpower, material and financial resources in the research and development of electric vehicles, and has achieved a series of scientific research results. With the deepening of the global energy crisis, the depletion of oil resources and the hazards of air pollution and global temperature rise Governments and automobile companies in various countries generally recognize that energy conservation and emission reduction are the main directions of future automobile technology development, and the development of electric vehicles will be the best way to solve these two technical difficulties.
