A Bidirectional Wireless Power Transfer for Electric Vehicle Charging in V2G System

Abstract

Wireless Power Transfer is a innovative technology in which power is transferred without physical contact. As technical knowledge is proceeding, the most of wired technology is also converting into wireless technology through different techniques. Electric Vehicles and plug-in hybrids may be fresh and feasible but it does not enough if it is forgetting to plug in power source the night before. Electric Vehicle will automatically charge when it will park in the special parking space where transmitter circuit has already been developed, when an electric vehicle park on that place, charging will start automatically. A preceding review of few methods for wireless charging discover that Inductively Coupled Power Transfer System (ICPT) is a advantageous method for wireless charging of EVs(Electric Vehicles). This paper presents a Bidirectional IPT(Inductively Coupled Power Transfer) system which is appropriate for Vehicle to Grid (V2G) systems. For EV charging A bidirectional WPT is a stable dynamic and effective system. Wireless power techniques falls into two categories, non-radiative and radiative. This research follows the non-radiative field using magnetic inductive coupling between coils of wire. In this project mutual inductance technique is used for wireless charging for transferring voltage (12 V) for charging of that battery at a considerable distance of 30 cm between two coils. This paper will also enhance the feasibility, reliability and efficiency of the system.
