Abstract

The invention discloses an electric vehicle wireless charging optimization system based on distributed energy consumption and belongs to the technical field of wireless charging. The system comprisesa transmitting unit and a receiving unit. The transmitting unit comprises an OLED module, a transmitting end controller, a controllable voltage stabilizing source, a photovoltaic panel, an MPPT control module, a lithium battery, a transmitting end measuring module and a transmitting coil set. The receiving unit comprises a receiving coil unit, a receiving end measuring module, a load interface anda receiving end controller. Technical problems that a magnetic field is integrated, a magnetic core with high magnetic conductivity plays a magnetic shielding effect, coupling structure flux leakageis reduced, and a magnetic field interference is eliminated are solved. A resonance inductor in an LCC compensation network is integrated on a main coil, the resonance coil and the main coil share themagnetic core, economy of the system is improved, a size of the system is remarkably reduced, the system is more compact, a double-end LCC structure is added to an existing XKT circuit, and overall electric energy transmission efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and relates to a wireless charging optimization system for electric vehicles based on distributed energy consumption. Background technique [0002] In recent years, electric vehicles have gradually become popular due to their energy saving and environmental protection, and the research on their charging issues has also attracted much attention. Wireless charging uses electromagnetic fields as the medium to transfer electric energy. Compared with traditional contact charging methods, wireless charging is safer, faster, more convenient and more efficient. [0003] Research in the field of wireless charging for electric vehicles generally involves coil design, compensation topology, power electronic converters and control methods, foreign object detection, safety, etc. [0004] Efficiency and compactness are two important indicators for wireless charging of electric vehicles. At present,...
