UPS电池容量计算方法有两种 即恒流法和恒功率法相比而言恒功率法比较准确 因电池放电过程中电流值是变化的一般配置时若有电池的恒功率放电参数表 由选用恒功率法。采用恒流法在长延时备电时才较准确。我司采用恒功率法的计算过程如下

先计算电池组所需功率=80*0.8/0.94=68.08KW(O.8是功率因数、 0.94是逆变效率

再计算单体电池所需功率=68.08*1000/192=354.6W384V系统是192个单体查H12V310/A电池的恒功率放电表在终止电池1.67V/CELL时单体功率为119W则354.6/119=2.98,因此取三组电池并联。

H系列电池是我司的高功率电池相比同容量下其恒功率数据要高。 同比在选用沈阳松下或EXIDE的电池时按其恒功率值选取则需三组12V100AH电池。以上
