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新型电源垫的设计和性能评估

电动汽车(EV)无线充电系统的引入是电动交通领域的革命性一步。发射和接收电源焊盘之间的未对准会显着影响 EV 无线充电系统的整体功率传输效率。在本文中,设计了一种名为“双 D 圆形”(DDC)的新型电源焊盘。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考虑发射和接收功率之间不同垂直和水平错位的功率传输效率,将其性能与现有圆形和双 D (DD) 电源垫的性能进行比较。垫。我们在仿真软件 ANSYS Maxwell 3D 中使用汽车工程师协会 (SAE) J2954 推荐做法中发布的物理尺寸,用于现有圆形和 DD 电源焊盘。文章中还评估了铁氧体板对电源焊盘性能的影响。
