An Adaptive Method for Wireless Charging Of Electric Vehicles

Abstract

A study about wireless power transmission system for electric vehicle to charge the battery during low-speed driving without stopping the vehicle is underway. Mutual induction based wireless power transmission is proposed. Time-varying magnetic flux is generated from the AC current of a power supply rail in accordance with Ampere’s law Voltage is induced from the pick-up coil, coupled with the power supply rail, in accordance with Faraday’s law Power is wirelessly delivered through magnetic coupling, where capacitor banks are used to nullify inductive reactance. This project works on the principle of wireless power transmission. Power is transmitted by means of electromagnetic waves. The vehicle is operated in Battery mode. The battery is charged by the wireless electric power. Battery is connected to the microcontroller. The energy transmitters (Magnetic wave transmitter) placed near magnetic wave receiver which gets the charge from the transmitter through electromagnetic waves. RF transmitter is used to provide control signals for movement of the robotic vehicle in wireless manner. RF transmitter sends the control signal to the receiver. RF receiver sends the signal to the microcontroller. And microcontroller sends this signal to the robotic motor through driver.
