Dynamic Wireless Power Transfer (DWPT) for Charging Application of Electric Vehicle

Abstract

In order to minimize the pollution, both public and private transportation sector, has turned their mindset to Electric vehicles (EVs). The most important and primary hurdle to money-oriented and spreading electric vehicle are the issues related to battery. In an Electric Vehicle, the most difficult component to design is the battery of Electric Vehicle, due to the requirements such as: high power and Energy density, safety, affordable cost, longevity, and reliability, should be met simultaneously. Moreover, continue charging and limited operating time due to low energy density are other issues to develop EV's worldwide. Dynamic wireless energy transfer, is a viable answer so that it will curb the problems associated with batteries. In this answer of Dynamic wireless power transfer (DWPT), the battery of electric vehicle (EV) can be charged when the automobile is in motion. Dynamic wireless power Transfer (DWPT) is the technology that uses the magnetic resonance and might set humans free from the demanding wires. In a Dynamic wireless power tranfer, the transmission coils are grounded while the Receiver coil is mounted under an electric vehicle (EV)). Through a adequate charging infrastructure large enough to charge the electric vehicle during motion the size of the batteries onboard can be minimized to large extent and the operating range of the vehicle can be extended to a great extent.
