The field of electric vehicle (EV) charging has seen significant advancements, with wireless charging systems emerging as a promising alternative to traditional plug-in methods. Inductive power transfer (IPT) technology, in particular, has undergone extensive research to improve its efficiency, power transfer capability, and tolerance to coil misalignment, which are critical for practical implementation in EV charging scenarios. Addressing challenges such as electromagnetic compatibility (EMC) and thermal management is also paramount for ensuring the reliability and safety of these systems [1].
A key innovation in this domain is the development of dynamic wireless charging systems, which allow EVs to recharge while in motion. These systems focus on the design and performance of segmented coil architectures and sophisticated power electronics to facilitate efficient energy transfer and minimize electromagnetic field exposure. The practical implementation hurdles and the potential to enhance urban mobility are crucial aspects of this research [2].
Further advancements have been made in enhancing the misalignment tolerance of wireless power transfer (WPT) systems for EV charging. Novel approaches, including the integration of Z-source inverters and optimized coil geometries, have demonstrated the ability to maintain high efficiency even with significant lateral and angular displacements between the charging pads. Extensive simulation and experimental validations support these findings [3].
Magnetic resonance wireless power transfer (MR-WPT) is another technology being explored for EV charging, offering distinct advantages such as longer charging distances and reduced sensitivity to alignment issues. The design of resonant coils and the capability for multi-load charging are key features, alongside careful consideration of efficiency and safety in practical applications [4].
Electromagnetic interference (EMI) and electromagnetic compatibility (EMC) are critical considerations for the widespread adoption of wireless EV charging. Research in this area focuses on developing effective shielding techniques and filtering methods to mitigate EMI problems, ensuring that these systems comply with international standards and do not interfere with sensitive electronic components within vehicles and charging infrastructure [5].
Thermal management of WPT coils is essential for the longevity and safety of EV charging systems. Analytical models have been developed to predict temperature distribution within the coils, and various cooling strategies are being proposed to prevent overheating, thus ensuring system reliability under demanding operational conditions [6].
The feasibility of implementing higher charging power levels (exceeding 100 kW) for wireless EV charging is also under investigation. This research delves into the associated challenges, including maintaining efficiency, managing magnetic field exposure, and addressing thermal issues at these elevated power levels, with potential solutions involving advanced coil designs and power electronics [7].
The integration of wireless EV charging infrastructure raises questions about power quality and grid interaction. Studies are examining the impact of multiple charging stations on the power grid, proposing control strategies to mitigate harmonic distortion and ensure efficient power factor correction, thereby supporting grid stability [8].
Comparative analyses of different coil topologies for inductive wireless power transfer in EV charging are being conducted to evaluate their efficiency and performance. This includes assessing various coil structures based on factors such as coupling coefficient, power transfer capability, and overall cost-effectiveness to guide design choices [9].
Finally, the optimization and control of wireless charging for entire fleets of electric vehicles are being addressed through unified frameworks. These frameworks consider aspects like scheduling, power allocation, and energy storage management to maximize charging efficiency and minimize the impact on the electrical grid [10].
