On-track Near-field Wireless Charging for Electrical Vehicles

Abstract

Nowadays inductive coil-based wireless power transfer is termed wireless charging, which is additionally referred to as magnetic resonance coupling and inductively coupled wireless power transfer (ICWPT) [1]. Wireless power transmission using magnetic resonance is the method that would lead to setting humans free from annoying wires and risky operations at the electric vehicle charging station. A huge power and capability battery-package are is always provided as an energy-containing device [5] [12]. Lithium Polymer or Lithium-Ion batteries are used in electrical vehicles (EV) which help an electric vehicle run for the desired travel limit [6]. But the earth has only about a few million tons of lithium, which is enough to power vehicles all over the world But nowadays electric vehicle charging methodologies need a lot of special structures. The major complication is the production of batteries in the market and the massive structural complexity with its overrated battery weight. This new design infrastructure helps electric vehicles charge while driving by using a shaped magnetic field wireless power transfer to overcome this problem. It is possible by providing power to a movable object across a gaped magnetic structure [2]. The Shaped Magnetic Field in Resonance technology delivers huge energy with caution to an electric vehicle when it's in a static position or motion. The development cost of the On-track near field wireless charging technique concept and its design is the same as other charging stations but comparing those methods, it is highly efficient and reliable [14]. This paper also provides experimental evidence for charging electrical vehicles wirelessly using on-track electrical vehicle charging technology.
