SAE J2954标准建立了一个行业范围的规范，该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、安全性和无线功率传输（WPT）测试的可接受标准。本规范定义了基于SAE J1772导电交流充电水平1、2和3的各种充电水平，并有一些变化。基于这些充电水平的WPT标准允许根据车辆要求选择充电率，从而允许更好的车辆包装和方便客户使用。该规范支持家庭（私人）充电和公共无线充电。在近期内，根据SAE J2954可以无线充电的车辆也应该能够通过SAE J1772插头进行传导充电- SAE J2954解决了从电网到车辆的单向充电问题；可以针对未来标准评估双向能量传递。本标准旨在用于固定应用（车辆未行驶时充电）；未来可以考虑动态应用。在该版本中，仅覆盖地面（表面安装）安装；已讨论过嵌入式安装，但尚未准备好包括在内。SAE J2954包含安全、性能和互操作性要求。它还包含评估电磁辐射的推荐方法，但要求和测试程序由监管机构控制。本标准中互操作性要求的开发采用了性能- 使用标准化测试站和程序对候选设计进行评估，从而确定用于确定产品可接受性能的参考装置。

The SAE J2954 standard establishes an industry-wide specification that defines acceptable criteria for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless power transfer (WPT) of light duty plug-in electric vehicles. The specification defines various charging levels that are based on the levels defined for SAE J1772 conductive AC charge levels 1, 2, and 3, with some variations. A standard for WPT based on these charge levels enables selection of a charging rate based on vehicle requirements, thus allowing for better vehicle packaging and ease of customer use. The specification supports home (private) charging and public wireless charging.In the near term, vehicles that are able to be charged wirelessly under SAE J2954 should also be able to be charged conductively by SAE J1772 plug-in chargers.SAE J2954 addresses unidirectional charging, from grid to vehicle; bidirectional energy transfer may be evaluated for a future standard. This standard is intended to be used in stationary applications (charging while vehicle is not in motion); dynamic applications may be considered in the future. In this version, only above-ground (surface mounted) installations are covered; flush mounted installations have been discussed but are not yet ready for inclusion.SAE J2954 contains requirements for safety, performance, and interoperability. It also contains recommended methods for evaluating electromagnetic emissions, but the requirements and test procedures are controlled by regulatory bodies. Development of the interoperability requirements in this standard employed a performance-based evaluation of candidate designs using a standardized test station and procedures, resulting in defining reference devices which are used to determine acceptable performance of products.
