标准摘要
[中文适用范围]： IEC 60904-5 描述了测定光伏器件（单一种类的电池、模块和组件阵列）的等效电池温度（ECT）的首选方法，旨在比较其热特性、测定 NOCT（名义工作电池温度）或 NMOT（名义模块工作温度），并将测量的 I-V 特性转换到其他温度。本标准适用于具有线性 VOC 随辐照度对数依赖关系且处于稳定条件下的器件。它可用于所有技术，但必须验证没有影响测量的预 conditioning 效应。 [外文原描述]： IEC 60904-5:2011+AMD1:2022 describes the preferred method for determining the equivalent cell temperature (ECT) of PV devices (cells, modules and arrays of one type of module), for the purposes of comparing their thermal characteristics, determining NOCT (nominal operating cell temperature) and translating measured I-V characteristics to other temperatures. The main technical changes with regard to the previous edition are as follows: - added method on how to extract the input parameters; - rewritten method on how to calculate ECT; - reworked formulae to be in line with IEC 60891.
