Wireless charge control method based on coordination control over voltage and frequency of power supply

The invention discloses a wireless charge control method based on coordination control over the voltage and the frequency of a power supply. The wireless charge control method mainly aims to meet the requirement for wireless charge power stability of an electric vehicle. A system mainly comprises the power supply, a transmitting device, a receiving device, a rectification and conversion device, a storage battery, a wireless transmitting and receiving module and a power tracking controller, wherein the frequency and voltage of the power supply are adjustable. According to the wireless charge control method based on the coordination control over the voltage and the frequency of the power supply, the resonant coupling type wireless electric energy transmission technology is adopted, the terminal voltage and the charge current of the storage battery serve as feedback, and constant-power or constant-voltage charge of the storage battery of the electric vehicle is realized through dual-ring coordination control over the power supply frequency and supply voltage. According to the wireless charge control method based on the coordination control over the voltage and the frequency of the power supply, the wireless charge power stability of the electric vehicle is effectively realized by the adoption of a control algorithm based on parameter feedback and double-variant coordination control, and the robustness of the system in operation is improved.
