Special Issue Information

Dear Colleagues,

The rapid evolution of electric vehicles (EVs) as a sustainable alternative to fossil fuel-powered transportation necessitates equally innovative advancements in charging technologies. Wireless power transmission (WPT) techniques, leveraging electromagnetic fields to transfer power over distance without physical connectors, offer a promising solution to enhance the usability and adoption of EVs. This Special Issue focuses on the cutting-edge developments in WPT, emphasizing its potential to revolutionize EV charging by eliminating the need for plug-in cables, thus facilitating greater convenience and operational flexibility.

Despite significant advancements, WPT for EV charging faces several challenges including limited efficiency at high power levels, the need for precise alignment between the transmitter and receiver, safety concerns related to electromagnetic exposure, and the integration of WPT systems into diverse urban environments. Additionally, the dynamic nature of vehicle operation demands the development of fast and reliable control methods to adjust power transmission in real-time, ensuring efficiency and safety under varying conditions.

This Special Issue seeks to explore these issues in depth, presenting the latest research aimed at overcoming these barriers and enhancing the overall viability of wireless charging for electric vehicles. Key areas of interest include improving transmission range and efficiency, developing adaptive alignment systems, ensuring user and environmental safety, and integrating these technologies into smart urban infrastructures.

We invite original contributions that explore various dimensions of wireless charging technologies, including but not limited to the following:

  • High-efficiency resonant converters;
  • Innovations in transmitter and receiver coil configurations;
  • Infrastructure requirements and integration challenges for dynamic WPT systems;
  • Control strategies for power flow management;
  • High-interoperability WPT systems;
  • Integration with smart grid and renewable energy sources;
  • Economic and environmental impact assessments;
  • Environmental impact assessments of widespread adoption of wireless charging;
  • Smart grid and IoT integration;
  • Consumer behavior and adoption challenges.

This Special Issue will serve as a premier platform for researchers, engineers, and industry professionals to disseminate their findings, exchange ideas, and foster collaborations that will drive forward the capabilities of wireless EV charging. By bridging technological research with practical implementations, we aim to address the challenges and leverage the opportunities within this dynamic field, paving the way for a more sustainable and efficient automotive future.

Inductive power transfer (IPT) systems are pivotal in various applications, relying heavily on the accurate estimation of mutual inductance to enable system interoperability discrimination and optimal efficiency tracking control. This paper introduces a novel mutual inductance estimation method for Series-Series IPT (SS-IPT) systems, utilizing time-domain modeling combined with nonlinear least squares. Initially, the time-domain model of SS-IPT systems is developed by deriving its ordinary differential equations (ODEs). Subsequently, the mutual inductance is estimated directly from these ODEs using a nonlinear least-squares approach. This approach necessitates only primary-side information, eliminating the need for communication, supplementary equipment, or frequency scanning. The simplicity and directness of using collected real-time data enhance the practical applicability of our approach. The effectiveness of the proposed method is substantiated through simulations and experimental data. Results demonstrate that the estimation accuracy of our method remains more than 95.0% in simulations and more than 92.5% in experimental data. Full article

The increasing demand for wireless power transfer (WPT) systems for electric vehicles (EVs) has necessitated advancements in charging solutions, with a particular focus on speed and efficiency. However, power transfer efficiency is the major concern in static and dynamic wireless charging (DWC) design. Design consideration and improvements in all functional units are necessary for an increase in overall efficiency of the system. Recently, different research works have been presented regarding DWC at the power converter, coil structure and compensators. This paper provides a comprehensive review of power converters incorporating high-order compensation topologies, demonstrating their benefits in enhancing the DWC of EVs. The review also delves into the coupling coil structure and magnetic material architecture, pivotal in enhancing power transfer efficiency and capability. Moreover, the high-order compensation topologies used to effectively mitigate low-frequency ripple, improve voltage regulation, and facilitate a more compact and portable design are discussed. Furthermore, optimal coupling and different techniques to achieve maximum power transfer efficiency are discussed to boost magnetic interactions, thereby reducing power loss. Finally, this paper highlights the essential role of these components in developing efficient and reliable DWC systems for EVs, emphasizing their contribution to achieving high-power transfer efficiency and stability.
