电动汽车能量传输系统 第1部分：功能要求和系统架构

[中文适用范围]： 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整个电动汽车能量传输系统 (EV-ETS) 的所有特性，以确保同一物理系统架构的电动汽车和 EVSE 的功能互操作性。无论架构如何，ETS 都负责将交流电能转换为直流电能，可用于为电动汽车的蓄电池充电，如图所示。 [外文原描述]： 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:aType A—Conductive AC System Architecture— Section 7.2.1bType B—Inductive System Architecture— Section 7.2.2cType C—Conductive DC System Architecture— Section 7.2.3The 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.
