Design and Analysis LCCL–LC Compensation for Electric Vehicle Systems

Abstract

The shift towards cars electric vehicle (EVs) plays a role in the global effort to combat climate change by reducing dependence on fossil fuels. An important part of this shift involves creating user EV charging systems. This study looks into how a connected coil design in a wireless power transfer system can help overcome challenges in EV charging when dealing with varying loads. We examine how well the system performs under load resistances that mimic states of charge and battery capacities in EVs. By assessing the stability of output voltage and efficiency of power transfer across these loads we focus on maintaining resonance within the system. Our findings show that the LCCL to LC WPT system maintains efficiency in power transfer 50–94% when coupling coefficient change (0–0.9) at load resistance 3 Ω and stable output voltage when facing changes in load resistance 1–4.5 Ω. This suggests that the system is resilient against load variations, which’s crucial for real world EV charging situations. This research supports the potential of WPT systems as an efficient solution to meet the evolving demands of EV infrastructure leading towards increased adoption of EVs and a sustainable future for transportation.
