A Comprehensive Design and Simulation of Highly Inductive Bi-directional Wireless Power Transfer

Abstract

This paper presents the design and optimization of a Bidirectional Wireless Power Transfer (BWPT) system for electric vehicles (EVs), enabling efficient two-way energy exchange between the grid and vehicle. The proposed system integrates with smart grids and renewable sources, enhancing sustainability. Robust control strategies manage smooth transitions between Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G) modes to maintain stability. Key design aspects – including component selection with appropriate ratings, resonant tuning, and alignment – are optimized to maximize efficiency and minimize losses. The system is modeled and simulated in MATLAB/Simulink under realistic conditions, demonstrating high performance: efficiency reaches 97.4% in G2V mode and 90.25% in V2G mode. These results highlight the practical viability of the BWPT design for future EV charging infrastructure.
