Wireless Battery Charger for EV with Circular or Planar Coils: Comparison

Abstract

This paper presents the experimental results obtained in the wireless energy transfer (WET) system prototype based on coils: circular or planar. With these experimental results we can choose the tuning settings to improve the efficiency of power transmission of the WET systems. In WET for electric vehicle batteries charging, the coil shape and the range between the coils are the most important issues of those systems.

Omnidirectional WPT and Data Communication for Electric Air Vehicles: Feasibility Study

“…While in [19,20], two magnetic core reactors (MCRs) are included at the transmitter and receiver sides to ensure the frequency control and to tune both ends at the same frequency, enabling the increase of the systems' performances by ensuring the impedance matching [16][17][18]. Furthermore, to advance the design of electric vehicles battery chargers using WPT technique, two different geometric configurations are compared in [21,22] in which the electrical three-phase system transmitter can be connected electrically and geometrically in a star or a delta configuration. In this paper, we focus on the analysis and design considerations of the induction-based wireless power supply and data communication through three-dimensional wireless channel inductive coupling for electric air vehicles such as UAV drones and AEA applications.…”
