Wireless Power Transfer for Vehicular Applications: Overview and Challenges

TLDR

Greenhouse‑gas‑emitting gasoline engines dominate transport, but electric vehicles promise eco‑friendly mobility, yet battery limitations—high cost, scarce materials, low energy density, and weight—remain a barrier that dynamic in‑motion charging could mitigate. The paper reviews recent advances in stationary and dynamic wireless charging of electric vehicles. The review covers dynamic in‑motion charging solutions, including charging pad designs, power‑electronics configurations, compensation networks, control strategies, and relevant standards. In‑motion charging can reduce battery storage needs and significantly extend electric‑vehicle driving range.

Abstract

More than a century-old gasoline internal combustion engine is a major contributor to greenhouse gases. Electric vehicles (EVs) have the potential to achieve eco-friendly transportation. However, the major limitation in achieving this vision is the battery technology. It suffers from drawbacks such as high cost, rare material, low energy density, and large weight. The problems related to battery technology can be addressed by dynamically charging the EV while on the move. In-motion charging can reduce the battery storage requirement, which could significantly extend the driving range of an EV. This paper reviews recent advances in stationary and dynamic wireless charging of EVs. A comprehensive review of charging pad, power electronics configurations, compensation networks, controls, and standards is presented.
