Abstract

The invention discloses an electric automobile wireless charging method and system based on a double transmission-double picking mode. The electric automobile wireless charging method based on the double transmission-double picking mode comprises the steps of inputting direct current voltage into two inverter circuits; enabling an output end of the first inverter circuit to load high frequency alternating current to a first primary side transmitting coil through a first primary side resonance circuit so as to generate a high frequency magnetic field; generating electric energy after sensing the high frequency magnetic field through a first secondary side picking coil; inputting the electric energy into a first buck-boost converter through a first secondary side resonance circuit and a first rectification filter circuit; enabling an output end of the second inverter circuit to load high frequency alternating current to a second primary side transmitting coil through a second primary side resonance circuit to generate a high frequency magnetic field; generating electric energy after sensing the high frequency magnetic field through a second secondary side picking coil; inputting theelectric energy into a second buck-boost converter through a second secondary side resonance circuit and a second rectification filter circuit; converting the electric energy into load electric energyby using the two buck-boost converters; and outputting the load electric energy to a series-connected load.

Description

Technical field [0001] The present invention relates to the technical field of electric vehicle wireless charging, and more specifically, to a wireless charging method and system for electric vehicles based on a dual-transmit-dual-pickup mode. Background technique [0002] At present, the research and development of electric vehicles has attracted the attention of major industrial countries in the world and the attention of major automobile manufacturers around the world. Electric vehicles have become one of the major development directions in the field of modern automobiles. There are two main charging methods for electric vehicles: plug-in wired power supply and wireless power supply. Compared with the problems of plug-in wired power supply, such as poor charging safety and flexibility, and insufficient infringement of outdoor wired charging piles, the wireless charging technology of electric vehicles eliminates the cable connection between charging equipment and electric vehic...
