Abstract

Wireless power transfer (WPT) technique for charging Electric Vehicles (EV) shows a promising impact on the EV industry. However, there is a lack of a 230V AC input wireless charger for EV. This research aims to investigate a 230V AC input wireless power transfer for electric vehicle application according to the Society of Automotive Engineers (SAE) standard. Using Finite Element Analysis (FEA), the study analyzed the parameters of transmitter and receiver coil of a magnetic resonance coupled (MRC) WPT system and measured power and efficiency using the parameters of the coils. In addition, the co-simulation environment between Ansys Maxwell and Ansys Simplorer was used to validate the results. The study shows an AC output power of the coil between 240W to 3.58kW at different distances with the highest coupling coefficient of 0.32. Besides, the analysis indicates that the system can operate at different frequencies with maximum power transfer. Further studies are needed to establish less flux linkage between the coils to achieve a higher output power for the system and calculate the power losses.
