Description

technical field [0001] The invention relates to a transmitting coil array control method for improving the interoperability of electric vehicle wireless charging, and belongs to the technical field of electric vehicle wireless charging. Background technique [0002] In recent years, due to its convenience, safety, and aesthetics, wireless charging technology has been widely used in the field of electric vehicle charging. The structure and working process of the wireless charging system for electric vehicles are as follows: Transmitter—the inverter converts direct current into high-frequency alternating current through DC-AC conversion, and the alternating current output by the inverter is connected to the transmitter installed on the ground or underground. In the coil, a high-frequency electromagnetic field is generated in the charging area; at the receiving end—the receiving coil installed on the chassis of the car induces the high-frequency electromagnetic field of the tra...
