Developing and Implementation of Contactless Stationary Charging System for Electric Vehicles

Wireless charging for electric vehicles eliminates the need of charging cables and connectors, making the process of charging easy, more convenient and user-friendly. It provides much safer and more efficient way of energy transfer by reducing the wear and tear of physical connectors. Additionally, it also provides automatic charging, which is useful particularly for autonomous vehicles. The proposed model mainly consists of two sections. They are namely, transmitting section and receiving section. The AC alternating current from main power supply is firstly converted to DC and DC converted to AC at primary coil or TX coil and the AC power is received at the RX coil and AC power is converted to DC at receiving coil to charge the battery. The main aim of this topology is to design a Wireless Power Transmission of electric vehicle without wasting the power. This method of charging uses mutual inductance principle as it consists of TX coil and RX coil which are used for charging, controller for monitoring the input and output voltages, a display for showing the percentage of charging and a buzzer for alarm indication when charging is low and when charging is full. It also uses rectifier, inverter and converters. Electric vehicles (EVs) offer numerous advantages over traditional fuel-powered vehicles such as regenerative braking, which enhances energy efficiency. With increasing availability of renewable energy sources, EVs have the potential to become even more sustainable.
