Review of static and dynamic wireless electric vehicle charging system

TLDR

Electrified transportation can reduce greenhouse‑gas emissions and rising fuel costs, but it requires diverse, user‑friendly charging networks; wireless electric vehicle charging systems provide a plug‑free alternative. This paper outlines the current wireless power transfer technologies available for electric vehicles. The authors review wireless transformer designs with various ferrite shapes, discuss health and safety considerations under current international standards, and describe static and dynamic WEVCS architectures and recent progress from laboratories, universities, and industry. Future concepts such as vehicle‑to‑grid and in‑wheel wireless charging systems are examined, with qualitative comparisons to existing technologies.

Abstract

Electrified transportation will help to reduce green-house gas emissions and increasing petrol prices. Electrified transportation demands that a wide variety of charging networks be set up, in a user-friendly environment, to encourage adoption. Wireless electric vehicle charging systems (WEVCS) can be a potential alternative technology to charge the electric vehicles (EVs) without any plug-in problems. This paper outlines the current available wireless power transfer technology for EVs. In addition, it also includes wireless transformer structures with a variety of ferrite shapes, which have been researched. WEVCS are associated with health and safety issues, which have been discussed with the current development in international standards. Two major applications, static and dynamic WEVCS, are explained, and up-to-date progress with features from research laboratories, universities, and industries are recorded. Moreover, future upcoming concepts-based WEVCS, such as "vehicle-to-grid (V2G)" and "in-wheel" wireless charging systems (WCS) are reviewed and examined, with qualitative comparisons with other existing technology.
