Research on Wireless Charging Technology of Electric Inspection Intelligent Car

Aiming at the problems that the distribution network cable pipelines are widely distributed, narrow and difficult inspection, the inspection intelligent car with STM32 microcontroller replaces the manual inspection. Inspection intelligent car is usually powered by self-provided battery. When the power is exhausted, it should be supplemented in time to ensure its normal inspection. Wireless charging can solve the problems of traditional contact charging, such as frequent plugging and unplugging of plugs, easy aging and generating electric sparks. In this paper, the series feeding model of two-coil type wireless charging system via magnetic coupling resonance is built, and the calculation method of scattering parameter

and system efficiency are derived to analyze power transfer capability and efficiency of the system. Based on the model, the wireless charging system of the inspection intelligent car is designed, which realizes wireless power transfer to the car battery within set time, and solves the problem of inconvenient charging.
