SAE J2293规定了对电动汽车(EV)和用于将电能从北美电力系统(Utility)传输到电动汽车的非车载电动汽车供电设备(EVSE)的要求。本文件直接或通过引用定义了总EV能量传输系统（EV-ETS）的所有特性，以确保相同物理系统架构的EV和EVSE的功能互操作性。无论架构如何，ETS都负责将AC电能转换为DC电能，DC电能可用于为EV的蓄电池充电，如中所示 图1 . 不同的物理ETS系统架构由EV和EVSE之间传输的能量形式来识别，如中所示 图2 EV和EVSE可以支持多于一种架构。 本文件不包含与电动汽车能量传输相关的所有要求，因为电动汽车和电动汽车供电设备的许多方面不会影响它们的互操作性。具体地，本文件不涉及EVSE和公用设施之间的接口的特征，除了承认公用设施是要转移到EV的能量源。 ETS的功能需求使用 功能分解 方法。在这里，需求被连续地分解成更简单的需求，并且需求之间的关系以图形形式被捕获。需求被写成输入到输出的转换，从而产生整个系统的模型。然后，将每个最低级别的要求分配给中所示的四个功能组(FG)之一 图2 这些组说明了三种不同系统架构的变化，因为它们所代表的功能将根据架构在EV上或在EVSE内实现。然后将用于在EV和EVSE之间传输电力和通信信息的通道的物理要求定义为架构的函数。系统架构变型如下所述: 一个 A型-导电交流系统架构-J2293-1- 6.2.1 b B型-感应系统架构-J2293-1- 6.2.2 c C型-导电直流系统架构-J2293- 6.2.3 中的需求模型 第6节 并不旨在规定特定的设计或物理实现，而是提供系统预期操作结果的功能描述。这些结果可以与任何特定设计的操作进行比较。根据本文件进行验证仅适用于EVSE和EV之间的物理边界。看 第8节 .

SAE J2293 establishes requirements for Electric Vehicles (EV) and the off-board Electric Vehicle Supply Equipment (EVSE) used to transfer electrical energy to an EV from an Electric Utility Power System (Utility) in North America. This document defines, either directly or by reference, all characteristics of the total EV Energy Transfer System (EV-ETS) necessary to insure the functional interoperability of an EV and EVSE of the same physical system architecture. The ETS, regardless of architecture, is responsible for the conversion of AC electrical energy into DC electrical energy that can be used to charge the Storage Battery of an EV, as shown in Figure 1 . The different physical ETS system architectures are identified by the form of the energy that is transferred between the EV and the EVSE, as shown in Figure 2 . It is possible for an EV and EVSE to support more than one architecture. This document does not contain all requirements related to EV energy transfer, as there are many aspects of an EV and EVSE that do not affect their interoperability. Specifically, this document does not deal with the characteristics of the interface between the EVSE and the Utility, except to acknowledge the Utility as the source of energy to be transferred to the EV. The functional requirements for the ETS are described using a functional decomposition method. This is where requirements are successively broken down into simpler requirements and the relationships between requirements are captured in a graphic form. The requirements are written as the transformation of inputs into outputs, resulting in a model of the total system. Each lowest level requirement is then allocated to one of four functional groups (FG) shown in Figure 2 . These groups illustrate the variations of the three different system architectures, as the functions they represent will be accomplished either on an EV or within the EVSE, depending on the architecture. Physical requirements for the channels used to transfer the power and communicate information between the EV and the EVSE are then defined as a function of architecture. System architecture variations are referred to as follows: a Type A—Conductive AC System Architecture—J2293-1— 6.2.1 b Type B—Inductive System Architecture —J2293-1— 6.2.2 c Type C—Conductive DC System Architecture—J2293— 6.2.3 The requirements model in Section 6 is not intended to dictate a specific design or physical implementation, but rather to provide a functional description of the system’s expected operational results. These results can be compared against the operation of any specific design. Validation against this document is only appropriate at the physical boundary between the EVSE and EV. See Section 8 .
