In road transportation, the market for electric vehicles (EVs) is considered a potential solution for addressing issues related to gas emissions and noise pollution. Due to the limited driving range of the EV battery pack, the charging process must be fast and safe for EV drivers. Wireless charging technology for EVs has gained attention in recent years, and in this research, the authors explore the analysis and design of a resonant magnetic wireless system for charging electric vehicles. The authors propose a design methodology for a serial–serial (SS) wireless system, which outlines how to determine the appropriate pad dimensions for transferring power to the EV battery. The design approach is crucial to attaining the best possible coupling performance and efficiency. Additionally, the magnetic design of the pad is validated using Ansys Maxwell software, and the proposed design is co-simulated using Ansys Simplorer to analyze the performance of the system. Simulation results demonstrate that the proposed model can transfer over 3.7 kW of power with an efficiency of over 90.02%. The paper also discusses the bifurcation phenomenon at the resonance condition to ensure maximum efficiency.

This article presents an in-depth study of a dynamic wireless power transfer (DWPT) system used to charge electric vehicles (EVs), with a focus on modeling and controlling a double-D (DD) coil structure. The chosen DD coil design improves energy transfer efficiency and minimizes mutual coupling between adjacent transmit coils, a common problem in dynamic applications. A comprehensive mathematical model is developed to account for the nonlinear dynamics of the system, i.e., when the vehicle is moving and misalignments and coupling variations occur. A robust nonlinear control method based on sliding mode control (SMC) is implemented to ensure stable operation and accurate regulation of the output voltage. The controller is tested in different scenarios where the vehicle speed changes, thus ensuring its robustness and stability under all operating conditions. Particular attention is paid to the critical transition zone, in which the receiver coil is placed between two transmitter coils in order to achieve minimal magnetic coupling. The simulation results demonstrate that the proposed controller offers a fast dynamic response (~0.07 s) and stable voltage tracking, even in the event of significant variations in mutual inductance and different EV movement speeds. These results confirm the effectiveness of the control approach and its potential for real-time charging of electric vehicles in large-scale DWPT applications.

Wireless power transfer (WPT) is becoming an attractive solution for charging electric vehicles (EVs). It offers greater convenience, reduces mechanical wear, and supports the development of automated and dynamic charging systems. However, the effectiveness of WPT-based EV chargers does not depend only on power electronics, coil design, and energy efficiency. Reliable wireless communication between the vehicle and the charging infrastructure is also essential. This communication link allows the system to identify and authenticate the vehicle, support coil alignment, regulate power transfer, monitor battery conditions, supervise safety, and manage possible faults. This review discusses the role of wireless communication technologies in the control of WPT EV charging systems. It also presents the main EV charging methods, the basic principles of WPT, its applications in electric vehicles, and key standards such as IEC 61980 and ISO 15118. In addition, the review compares Wi-Fi, Bluetooth, NFC, Zigbee, V2X, and cellular communication in terms of their suitability for WPT control. It also highlights major challenges, including electromagnetic interference, latency, cybersecurity, coil misalignment, system complexity, and standardization issues. Overall, future WPT EV chargers will need secure, reliable, and low-latency communication integrated with control and power transfer systems to achieve safe, efficient, and intelligent wireless charging.
