3. ABSTRACT Wireless Power Transfer (WPT) charging system for electric vehicles (EVs) is a promising technology that eliminate the need for physical cables offering a more convenient and user-friendly charging experience. This provides an overview of the benefits of wireless charging, including reduced wear and tear on charging equipment, enhanced user convenience, reduced infrastructure maintenance costs and enhanced safety and the potential for autonomous charging in the future. The techniques developed for EV dynamic charging includes inductive coupling and magnetic resonance coupling. However, Inductive Wireless Power Transfer technology (IWPT) faces the challenge of poor power transfer efficiency which can leads to high power consumption, and limited to shorter distances. The analysis of power consumption and power transfer efficiency with different frequencies are performed by using Magnetic resonance coupling technique. The results are analysed with the aid of simulation in MATLAB/Simulink software.

4. INTRODUCTION One of the main concerns with conductive charging or wired charging is high power cables to plug EV (Electric Vehicle), those are difficult to handle. Hazards can happen due to damaged cables or mishandling. An alternative new technology is Wireless power transfer (WPT), with the time this technology developed and became competitive solution for wired charging systems. Wireless Power Transfer (WPT) technology, The Inductive Power Transfer (IPT) method, which is based on the magnetic coupling of coils exchanging power from a stationary primary unit to a secondary system onboard the EV. The Resonant Inductive Power Transfer (RIPT) is improved model of traditional Inductive Wireless Power Transfer (IWPT), in terms of power transferring capability, designing and coupler coils. The resonant coupling is used to achieve efficient power transmission.

19. ADVANTAGES [Proposed System] Resonant coupling allows for higher efficiency, with higher power transfer rates. Unlike standard inductive charging, which is limited to just a few millimeters of distance between the transmitter and receiver, resonant coupling works even at relatively long distances. Traditional inductive charging requires precise alignment between the transmitter and receiver coils for efficient power transfer. Resonant wireless charging, on the other hand, does not require tight alignment.

20. COMPARISION OF PROPOSED SYSTEM WITH EXISTING SYSTEM In Inductive Wireless Power Transfer (IWPT) technology for electric vehicle dynamic charging, The simulation has been implemented using this IWPT technology gives the overall efficiency of 94.75% with an input of 10kw. However, inductive wireless power transfer technology (IWPT) faces the challenge of poor power transfer efficiency which can leads to high energy consumption and it is efficient only at shorter distances, longer distances results in reduced efficiency hence leads to low battery performance. In order to enhance the power transfer efficiency which is minimizing energy losses during wireless charging and to operate efficiently even at greater distances between transmitter and receiver coils, Resonators having high quality factors are adapted. They transmit energy at much higher rate, so by operating at resonance even with weaker magnetic fields can transmit the same amount of power in the inductive wireless charging for electric vehicle.

21. CONCLUSION In conclusion, wireless charging technologies have proven to be a promising solution for electric vehicles (EVs). These technologies offer several advantages, including convenience, efficiency and hassle-free charging. By eliminating the need for physical plug-in connections, wireless charging improves the user experience and simplifies the charging process. Among the Inductive Wireless Power Transfer (IWPT) and Resonance Inductive Wireless Power Transfer (RIPT) technologies, RIPT offers significantly more benefits such as high efficiency even at larger air gaps. However, IWPT has poor efficiency at longer distances between transmitter and receiver coils. So the RIPT technology is more suitable for Electric vehicle dynamic charging.
