Electric Vehicle Charge Dynamic Wireless Power Transfer

Abstract

Gasoline-powered vehicles have historically been a significant source of greenhouse gas emissions, prompting a shift towards more sustainable transportation solutions. Plug-in electric vehicles (PEVs) have emerged as a cleaner alternative; however, their widespread adoption is hindered by several technological challenges, including the high cost of batteries, their bulk and weight, slow charging speeds, and low energy density. These issues can create consumer hesitance due to concerns about charging infrastructure and range anxiety. To address these limitations, Dynamic Wireless Power Transfer (DWPT) has been proposed as an innovative solution that allows electric vehicles to charge while in motion. This technology utilizes specially equipped roadways to provide continuous power, enabling smaller battery packs and reducing vehicle weight. Unlike stationary wireless power transfer systems that only charge parked vehicles and do not extend driving range, DWPT offers a promising approach to enhance the practicality and appeal of electric vehicles, potentially contributing significantly to a more sustainable transportation future.
