电动道路车辆

[中文适用范围]： 本文件与 ISO 5474-1 结合，规定了在电动道路车辆和外部电路之间使用电压高达 1 500 V dc 的直流电 (DC) 进行传导式电力传输的要求。本文件规定了按照 IEC 61851-1 在模式 4 下传导充电的要求。对于模式 4，本文件规定了按照 IEC 61851-23 仅使用隔离直流 EV 电源设备进行电力传输的要求。本文件中的要求适用于车辆电源电路。附件 B 给出了兆瓦级充电应用要求的概述。本文件不提供： — 同时操作多个电力传输接口的要求和 — 驾驶时电力传输的要求（电动道路系统），但这些要求正在考虑中。本文件不提供： — 轻便摩托车和摩托车的要求（在 ISO 18246 中规定）； — 面向制造、维护和维修人员的全面安全信息。 [外文原描述]： This document in combination with ISO 5474-1 specifies requirements for conductive power transfer using direct current (DC) with a voltage up to 1 500 V d.c. between electrically propelled road vehicles and external electric circuits. This document provides requirements for conductive charging in mode 4 according to IEC 61851-1. For mode 4, this document provides requirements regarding the power transfer only with isolated DC EV supply equipment according to IEC 61851-23. The requirements in this document are applicable to vehicle power supply circuits. An outlook of requirements for megawatt charging applications is given in Annex B. This document does not provide: — requirements for simultaneous operation of multiple power transfer interfaces and — requirements for power transfer while driving (electric road systems) but they are under consideration. This document does not provide: — requirements for mopeds and motorcycles (which are specified in ISO 18246); — comprehensive safety information for manufacturing, maintenance and repair personnel.
