重型电动汽车的无线电力传输

[中文适用范围]： 已发布的 SAE J2954 标准建立了行业范围的规范，定义了轻型插电式电动汽车的互操作性、电磁兼容性、EMF、最低性能、安全性和无线电力传输 (WPT) 测试的可接受标准。这份 SAE 信息报告 SAE J2954/2 定义了重型电动汽车所需的更高功率范围内的新功率传输水平。本文件解决了基于这些充电水平和不同车辆应用的要求，作为完成行业可使用的标准的第一步，该标准适用于私人（车队）和公共无线电力传输，包括电动汽车电池充电。本文档是实现高清静态和动态 WPT 过程的第一步。该文件缺乏具体要求和解决方案，需要现场数据。 [外文原描述]： The published SAE J2954 standard established an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless power transfer (WPT) for light-duty plug-in electric vehicles. This SAE Information Report, SAE J2954/2, defines new power transfer levels in the higher power ranges needed for heavy-duty electric vehicles. This document addresses the requirements based on these charge levels and different vehicle applications as a first step in the process of completing a standard that the industry can use, both for private (fleet) and public wireless power transfer, including for charging electric vehicle batteries.This document is the first step in a process towards HD static and dynamic WPT. This document lacks specific requirements and solutions, for which field data is needed. This document is not intended to be a guideline to enable manufacturers to design systems with minimal assistance; the goal is to inform readers about many of the things to consider in addressing this market and is an outline for the SAE J2954/2 committee for continued work. Based on data, there will be much more detail in the next version of this document. This document represents experience from the SAE J2954 light-duty standard along with active participation of industry providers developing and deploying non-standardized HD wireless power transfer systems with the goal of creating standardized systems in the future.SAE J2954/2 addresses unidirectional power transfer, from grid to vehicle; bidirectional transfer may be evaluated for a future document. This document is intended to be used in stationary applications (power transfer while vehicle is not in motion) and some dynamic applications.SAE J2954/2 covers requirements for safety, performance, and interoperability. Further development of detailed requirements will be based on performance-based evaluations of candidate designs, including evaluations against electrical safety and human safety StandardDetails.SAE J2954/2 also covers recommended methods for evaluating electromagnetic emissions, but the requirements and test procedures are controlled by regulatory bodies.Cross Reference:
