Optimization of Dynamic Wireless Charging Efficiency Using Bypass Charging Technique

The continuous advancement of electric vehicles (EVs) calls for the improvement of existing charging methods to address key issues such as efficiency loss, high battery dependence, and thermal instability. Our project explores the integration of bypass charging within dynamic wireless power transfer (DWPT) systems using MATLAB Simulink. The importance of improving charging methods lies in achieving higher energy efficiency, reducing battery strain, and supporting continuous charging during motion. Bypass charging, which directly powers the vehicle’s drivetrain instead of routing energy through the battery, boosts system efficiency by 5-10% over conventional DWPT systems, which typically operate at 60-70% efficiency.Our project study mainly focuses on simulating this bypass mechanism and analyzing its benefits compared to traditional charging systems. Since batteries account for nearly 40% of an EV’s total cost, reducing their size leads to significant advantages: lower production costs, lighter vehicle weight, and reduced thermal issues due to fewer charge-discharge cycles. The findings of our project are especially useful to consumers, as they offer a practical solution for enhanced EV performance, lower maintenance needs, and cost savings. While DWPT is already being implemented in places like Sweden and the U.S., bypass charging is still largely unexplored. This project aims to fill that gap by proposing an efficient, scalable, and consumer-friendly solution for the future of EV mobility.
