An Advanced Inductively Coupled Wireless Charging System For Electric Vehicle Applications

Abstract

Any day today, the globe transitions to electrified transportation, reducing non-renewable fossil fuel pollutant emissions. Electromagnetic energy is transferred from the power source to the electrical charge without interconnection wires and the operation is carried out in every device. Electric cars are seen in the potential mobility area to be substitutions for the vehicles propelled by oil fueled internal combustion engine. In this project wireless charging technologies are examined using the inductive coupling approach. Numerous factors, including magnetic flow, inductance of the resonant bob, determine the performance of wireless power transfer and mutual inductance. The paper focuses in particular on static (stationary) charge, while dynamic loading (loading during driving) involves a dramatically different method. The Multi-Load method is modelled and the efficiency expression for each charge is determined with a different resonant frequency.
