Abstract: Based on the energy conservation endurance race in the 2021 Jiangsu Robotics Competition, this paper builds a wireless constant power charging car based on super capacitor. The car receives the resonance signal from the transmission coil laid on the ground through the resonance coil with a specific frequency, and rectifies the resonant AC power into DC power for the whole vehicle. STM32F407 chip is used as the main control chip of the car, and the Farad capacitor bank on the car is charged by constant power control algorithm. In this paper, the wireless receiver module, constant power module and super capacitor module involved are designed to realize the energysaving operation of the car. Finally, the advantages of constant power charging are verified by experiments.
Keywords: wireless charging; super capacitor; constant power; STM32F407
