标准摘要
[中文适用范围]： 本部分IEC 60904描述了测定光伏器件（电池、组件和同类型组件阵列）等效电池温度（ECT）的首选方法，用于比较其热特性、确定NOCT（标称工作电池温度）以及将测得的I-V特性转换到其他温度。该标准适用于具有对数Voc依赖辐照度的线性器件，且在稳定条件下。可用于所有技术，但必须验证不存在影响测量的预 conditioning 效应。 [外文原描述]： IEC 60904-5:2011 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.
