“…The SRCs form an essential part of the Impedance Matching Circuit (IMC). The SRCs are inductively coupled to the transmitter and receiver coils [5]. When an impedance mismatch due to misalignment occurs between the WPT's transmitter and receiver unit, the IMC shall detect and flag it to the user, giving the user the opportunity to either continue, stop its operation, or hop to the alternative OpF of the WPT see Fig.…”

“…Wireless Power Transfer (WPT) is the technology of transferring electric energy wirelessly from a source to its load using resonant magnetic flux. WPT technology has been commonly used in electronic devices such as mobile phones, electric toothbrushes, inductive cookers, and biomedical equipment, and now being used for EV charging [5,7]. The Qi standard defines parameters for low power WPT (5W to 15W) at 100kHz operating frequency [8,9].…”

With the apparent reliability of wireless power transfer technology, Original Equipment Manufacturers are gradually migrating electric vehicle production charging modes from conductive to wireless. The increased users of electric vehicle wireless power transfer will introduce additional electromagnetic signals in the low frequency bandwidth which could cause interferences to various wireless operating systems. It is worth noting, vice versa, that the operation of the wireless power transfer can also be affected by near field propagated electromagnetic signals. This study shows a simplistic method to secure the electric vehicle's wireless power transfer operation from interference by providing simple resonant frequency hopping. A wireless power transfer system with a consolidated 85kHz, recommended by the Society of Automotive Engineers and non-standardized operating frequency of 250kHz was designed to this effect. The selection of 250kHz was based on a separate study detailed in this report.
