Electric vehicle charging system based on wireless electric energy transmission

Abstract

Disclosed is an electric vehicle charging system based on wireless electric energy transmission. The electric vehicle charging system comprises a charging pile and a wireless electric energy receivingdevice; the charging pile includes a lifting control part, an automatic alignment device and a wireless electric energy emitting device. The lifting control part includes a signal acquisition module,a first signal processing module, a first microprocessor, a first driving module, a first execution module and a second execution module. The automatic alignment device consists of a signal emittingsystem and a signal receiving system. The wireless electric energy emitting device comprises a power supply port, a first rectifier, a first DC-DC converter, a high-frequency inverter, an emitting coil, a wired direct current charging module and a wired alternating current charging module. The wireless electric energy receiving device comprises a receiving coil, a second rectifier, a second DC-DCconverter and a battery access port. According to the electric vehicle charging system, a wind-solar complementary power generation system is adopted as a power supply source of the electric vehicle charging pile, and the problem is solved that the power generation voltage output by wind-solar complementary systems and other new-energy power generation systems is low.
