2018 Electronic Competition Question C-Wireless Charging Electric Car

This article mainly describes the design of a wireless charging electric car based on supercapacitors and mechanical cars. First make a wireless charging device and place its transmitter coil on the road. The transmitter is powered by XKT901 with electromagnetic induction and automatically switched DC stabilized power supply. Under the condition that the supply voltage is 5V and the supply current is no more than 1A, the electric vehicle uses supercapacitors (Farad capacitors) of appropriate capacity to store energy. Finally, when the electric vehicle detects that the wireless charging transmitter has stopped charging, it will immediately start on its own and drive forward in a straight line until the energy is exhausted. The electric vehicle will then drive straight uphill along the inclined wood board road. Based on previous control experiences and experiments on wireless charging electric vehicles, appropriate capacitance capacitors were selected, and improvement measures were proposed for the main reasons. Comprehensive factors, observe operational data. Further adjustments and corrections will be made based on the data. In the process, problems were analyzed and solved, and certain experience was accumulated for the design and control of wireless charging electric vehicles.
