Challenges and Barriers of Wireless Charging Technologies for Electric Vehicles

Abstract

Electric vehicles could be a significant aid in lowering greenhouse gas emissions. Even though extensive study has been done on the features and traits of electric vehicles and the nature of their charging infrastructure, network modeling for electric vehicle manufacturing has been limited and unchanging. The necessity of wireless electric vehicle charging, based on magnetic resonance coupling, drove the primary aims for this review work. Herein, we examined the basic theoretical framework for wireless power transmission systems for EV charging and performed a software-in-the-loop analysis, in addition to carrying out a performance analysis of an EV charging system based on magnetic resonance. This study also covered power pad designs and created workable remedies for the following issues: (i) how power pad positioning affected the function of wireless charging systems and (ii) how to develop strategies to keep power efficiency at its highest level. Moreover, safety features of wireless charging systems, owing to interruption from foreign objects and/or living objects, were analyzed, and solutions were proposed to ensure such systems would operate as safely and optimally as possible.

Overview of the Thermal Runaway in Lithium-Ion Batteries with Application in Electric Vehicles: Working Principles, Early Warning, and Future Outlooks

“…Resonant electromagnetic induction, also known as inductive charging, is used in this method for wireless EV charging to carry an electrical current. − The same principle applies to wireless charging for EVs; when the two pads line up, charging starts thanks to a magnetic coil in the charger sending current to a coil on the underside of the vehicle (Figure ). However, the battery management system in electric vehicles must also be compatible with the wireless charging system and must be able to control the battery system to not charge for too long or to be overloaded to avoid the phenomenon of battery bottles or even fires at the charging station.…”
