Wireless Charging System for Electric Vehicles

Dear Colleagues,

EV technology has proven to be a propulsion technology of the future. However, there is an urgent need to address challenges of lowering price, creating reasonably sized EVs for higher market penetration, higher lifecycle efficiency, and increased power density. Nonetheless, this does not solve the issue related to reluctance to adopt EVs due to a lack of a broad network of charging stations or limited range/autonomy. What is more, gender is one of the different sociodemographic factors (income, age, mobility pattern, etc.) pushing towards EV adoption. Women seem to prefer the benefits of an EV (environmental impact, fuel economy, ease of operation) but still rank lower on their potential EV interest, despite being the most important users in an urban driving scenario. Recent accounts indicate that EV charging operators need to prioritize women’s safety to not lose or miss out potential users. A lack of lighting and the positioning of public EV chargers in more isolated places do not contribute to the notion of security deemed so important by women. Therefore, range extension, has become critical in both urban and remote scenarios. Wireless charging technology, and in particularly inductive power charging, solves simultaneously the electric hazard risks of conventional power cord battery chargers, but specially EV limited autonomy and related anxiety and even security.

More recently research has shifted towards a focus on the challenges imposed by dynamic operation modes, where cost-effective analysis of the best dynamic configuration, leakage flux control techniques, and optimization of the transmitter pads are lacking. State-of-the art solutions with compact in the wheel approaches have also emerged and multiple-coupling systems are becoming more apparent.

This Special Issue aims to present and disseminate the most recent advances related to the previous presented field. Nonetheless, wireless charging for EVs is not limited to cars or higher power vehicles. Other wireless charging applications in the field of electric mobility are subjects of interest such as underwater or airborne vehicles, industrial machines. We invite submissions related to the integration of artificial intelligence or machine learning techniques, as well as communication networks with wireless charging capacities for electrical mobility. The purpose of this publication is to disseminate applications, strategies and or technologies that contribute towards a mature transition to a greener, safer and more sustainable future in electric transportation.

Topics of interest for publication include, but are not limited to:

1. Opportunities and feasibility of dynamic and quasi-dynamic IPT systems (industrial, highways, low traffic, controlled movement, stop and go), interoperability.
2. High-order resonant configurations and/or multiple coupling systems for wireless charging in EVs.
3. Sizing vs energy transfer capability for DIPT.
4. Tolerance in IPT systems.
5. Wireless charging systems for underwater and airborne EVs.
6. Artificial Intelligence in wireless charging systems for EVs.
7. Integration of communication networks with wireless charging for electrical mobility.
8. High-Power IPT applications.
9. Configuration topologies for DIPT system feeding arrangements.
10. Trends and critical updates for related standards.
