标准摘要
[中文适用范围]： 本部分 IEC 62933 适用于电池储能系统（BESS）发生非计划性修改的情况。这些修改可能涉及以下一项或多项： - 储能容量的变化； - 累积子系统化学、设计和制造商的变化； - 使用非原厂零件的子系统组件的变化； - 操作模式的变化； - 安装地点的变化；或 - 由于安装再利用或重新用途的电池导致的累积子系统的变化。 任何此类修改都可能损害 BESS 的原始安全状态。 本文件是对 IEC 62933-5-2 的补充，该标准涉及 BESS 的整体安全方面。本文件涵盖的要求是根据每种情况在 IEC 62933-5-2 的要求之外额外应用的。 [外文原描述]： IEC 62933-5-3:2023 applies to those instances when a BESS undergoes unplanned modifications. Such modifications can involve one or more of the following: - changes in energy storage capacity; - changes of chemistries, design and manufacturer of the accumulation subsystem; - changes of a subsystem component using non-OEM parts, - changes to the mode of operation, - changes of the installation site, or - changes in an accumulation subsystem due to an installation of reused or repurposed batteries. Any such modification can impair the original state of safety of the BESS. This document complements IEC 62933-5-2, which relates to the overall safety aspects of a BESS. The requirements covered by this document are applied in addition to the requirements in IEC 62933-5-2 in accordance with each situation.
