Abstract

A substantial interest in inductive power transfer (IPT) is due to its straight forwardness and dependability in charging electric vehicle (EV) batteries for researchers. The mutual inductance (MI) plays a critical role in the IPT system as it enables efficient power transfer. Therefore, it is imperative to examine the MI between the two coils that are connected through inductive coupling. This work investigates the MI and efficiency of connected coils in interoperable conditions. The transmitter coil is arranged in the shape of a square (TxS), whereas the reception coil is arranged in the shape of a circle (RxC). A concise and user‐friendly collection of design guidelines for S‐S compensated resonant inductive power transfer (SS‐RIPT) systems the design concepts efficiently mitigate the possibility of systematically and unambiguously setting the specifications for a given load profile. A 3.6‐kW setup has been constructed and validated by finite element analysis and experimental testing, following the design specifications. The availability of suitable testing equipment in the laboratory influenced the choice of a resonance frequency and output voltage for a 3.6 kW system.

用于不同错位无线电动汽车电池充电系统的可互操作方圆耦合线圈

感应式功率传输（IPT）在为电动汽车（EV）电池充电方面的直接性和可靠性引起了研究人员的极大兴趣。互感（MI）在 IPT 系统中起着至关重要的作用，因为它能实现高效的功率传输。因此，必须研究通过电感耦合连接的两个线圈之间的互感。这项工作研究了互操作条件下连接线圈的 MI 和效率。发射线圈布置成正方形（TxS），而接收线圈布置成圆形（RxC）。S-S 补偿谐振电感功率传输（SS-RIPT）系统设计指南集简明易懂，设计理念有效降低了为给定负载情况系统地、明确地设定规格的可能性。根据设计规范，我们建造了一个 3.6 千瓦的装置，并通过有限元分析和实验测试进行了验证。实验室中是否有合适的测试设备影响了对 3.6 千瓦系统的共振频率和输出电压的选择。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
