Novel Technology development for High Power Vehicle Charging using Multiple Stage IPT System

Abstract

The growing awareness of CO2 and the less cost of electric vehicles contribute to the rapid growth of electric mobility (EV). Expanding EV market segments between recently sold automobiles show the move toward environmental mobility. However, more development is needed to eliminate the technological obstacles currently preventing a wide-scale deployment. On the one hand, the regulated electrical dynamic range and lengthy battery charge times of today’s EVs are addressed by developing the storage of electrical energy devices with increasingly better energy and power densities. Therefore, one of the most promising strategies for lowering the use of fossil fuels is regarded to be vehicle electrification. But since it takes so long and requires both human and mechanical labour, battery charging is still one of the significant obstacles to electrification. This paper’s main objective is to create a modular inductive power transfer (IPT) system with high DC-battery efficiency and power density. The simultaneous consideration of numerous design objectives is accomplished through a multi-objective optimization procedure. Electromagnetic finite element method calculations are combined with analytical models to compute the power losses, the stray magnetic field, and the required construction volume of the IPT coils.
