EVs are the recent emerging automotive technology in the transportation sector to reduce the CO2 emission from the internal combustion engine. The issues in EVs technology development are battery tube capacity, heavy-size batteries, fast charging, and safe charging infrastructure. The dynamic wireless charging technology shows a suitable alternative to address the charging system-related issues in EV. However, a limited number of review studies are conducted to specifically address the wireless charging pad design challenges. The wireless inductive power pad and magnetic coupling circuit design are the main factors to decide the performance of the DWPT system. This review analyzes the current developments and challenges associated with wireless charging pad design. Further, this study investigates the potential parameters which improve the performance of a DWPT system to increase the distance traveled (mileage). First, this paper discusses WRIPT technology for DWPT EV charging application, and several parameters affecting the PTE are examined. Also, the aids factors considered for designing the DWPT power pad and different magnetic resonance coupling topologies are presented. In addition, the performance evaluation of the WRIPT power pad, with in-motion testing from the major findings in earlier studies is discussed. Finally, the challenges and opportunities of the WRIPT power pad for in-motion EV charging applications are also addressed. The current state of the art of DWPT and its future directions to make DWPT EV charging systems a fullfledged method are highlighted.

Summary Wireless power transmission (WPT) is becoming a more viable idea and creative solution, particularly for the battery charging of electric vehicles (EVs). Inductive power transfer (IPT) is a widely used wireless charging technology. Here, the energy transformation takes place between two coils that are magnetically coupled. WPT has recently increased the interest of researchers because it is such a secure, easy, and dependable method of recharging EVs. This article gives an idea to design the charging coils using WPT system by using resonant inductive coupling and also optimizes the coupling coefficient using rain optimization algorithm (ROA). Wireless power transfer based on inductive coupling may perhaps potentially be applied in many real‐world applications. This article uses ANSYS MAXWELL and FEMM 4.1 software tools to analyze the results for 2D and 3D coil WPT systems. From these software simulation results, it has been illustrated that the distribution of flux between Tx and Rx is analyzed for spiral and rectangular coil shapes. The selected coupling coefficient is 0.08. At 95 kHz, the inductance is 34.76 italicμH, the mutual inductance is 9.16 italicμH, and the coupling coefficient is 0.2635. Highlights Design an efficient circuit to enhance the whole performance of WPT system. Self‐inductance, mutual inductance, and coefficient of coupling parameter are analyzed. Rain optimization algorithm is designed to optimize the parameter for enhancing the efficiency.

To improve the reliability in wireless power transfer system, communication is widely used. An independent coil as the signal coil for data transfer has the advantage of decoupling power coupling mechanism and signal coil when designing the system. Besides, in some application, vertical offset of the power coil may impact the stability of the system, position detection of the receiver side power coil is needed. Method of using the signal coil for vertical offset detection is adopted in this paper, simulation result verified the feasibility. The vertical offset of the power coil can be estimated by an exponential function based on the system parameter and the current of the primary side power coil. The exponential fitting function used in the paper can be used as a reference when designing the detection.
