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.
