Abstract

The introduction of wireless charging systems for electric vehicles (EVs) is a revolutionary step in the field of electrified transportation. Misalignments between transmitting and receiving power pads significantly affect the overall power transfer efficiency of an EV wireless charging system. In this article, a new power pad named “double D circular” (DDC) is designed. To evaluate the proposed DDC power pad design, its performance is compared with that of the existing circular and double D (DD) power pads by analyzing the power transfer efficiency in the wireless charging system considering different vertical and horizontal misalignments between the transmitting and receiving power pads. We use physical dimensions published in the Society of Automotive Engineers (SAE) J2954 recommended practice for existing circular and DD power pads in the simulation software, ANSYS Maxwell 3D. The influence of ferrite plates on the performance of power pads is also evaluated in the article.

电动汽车无线充电系统中一种新型电源垫的设计与性能评价

电动汽车无线充电系统的引入是电气化交通领域革命性的一步。在电动汽车无线充电系统中，发射和接收电源垫之间的错位会严重影响系统的整体功率传输效率。本文设计了一种名为“双D圆”(DDC)的新型电源垫。为了评估所提出的DDC电源垫设计，通过分析无线充电系统中不同发射和接收电源垫之间的垂直和水平错位，将其性能与现有圆形和双D (DD)电源垫进行比较。我们在仿真软件ANSYS Maxwell 3D中使用了汽车工程师协会(SAE) J2954推荐实践中发布的现有圆形和DD电源垫的物理尺寸。本文还评价了铁氧体板对电源垫性能的影响。
