电动车辆蓄电池交换系统第3部分:与可拆卸RESS/蓄电池系统一起运行的蓄电池交换系统的特殊安全性和互操作性要求

[中文适用范围]： 本标准适用于电动汽车的可拆卸车载储能系统（RESS）换电系统，当连接至供电网络时，额定供电电压最高为480 V交流电或400 V直流电，电池系统额定电压最高为120 V直流电。本标准适用于电池换电系统中可拆卸的RESS/电动汽车，其中可拆卸的RESS/电动汽车被储存以便在电池换电站和可拆卸的RESS/电动汽车之间进行电力转移。本标准适用于：由现场储能系统（例如缓冲电池等）供电的电池换电系统；手动、机械辅助和自动系统；旨在为具有通信功能的可拆卸电池系统提供识别电池系统特征服务的电池换电系统；旨在安装在海拔高达2000米处的电池换电系统。 [外文原描述]： IEC PAS 62840-3:2021 applies to battery swap systems for removable RESS of electric road vehicle when connected to the supply network, with a rated supply voltage up to 480 V AC or up to 400 V DC, for battery systems with a rated voltage up to 120 V DC. This document applies to battery swap systems for removable RESS/EV where the removable RESS/EV is stored for the purpose of transfer power between the battery swap station and removable RESS/EV. Requirements for bidirectional energy transfer DC to AC are under consideration and are not part of this document. This document applies to: – battery swap systems supplied from on-site storage systems (for example buffer batteries etc; – manual, mechanically assisted and automatic systems); – battery swap systems intended to supply removable battery systems having communication allowing to identify the battery system characteristics; – battery swap systems intended to be installed at an altitude of up to 2 000 m. The aspects covered in this document include: – requirements for power transfer between the battery systems; – additional requirements for communication; – the connection to supply network. Additional requirements may apply to special locations. This document does not apply to: – safety requirements for mechanical equipment covered by ISO 10218 (all parts); – locking compartments systems providing AC socket-outlets for the use of manufacturer specific voltage converter units and manufacturer specific battery systems; – safety aspects related to maintenance; – electrical devices and components which are covered by their specific product standards; – trolley buses, rail vehicles; – any on-board equipment which is covered by ISO; – EMC requirements for on-board equipment while connected to the supply, which are covered by IEC 61851-21-1. Requirements for battery swap systems using protective measures as covered by 410 of IEC 60364-4-41:2005 other than double or reinforced insulation are under consideration.
