摘要
高效的车用动力电池作为汽车的新型能源而言十分重要.建立合理的电池模型对于研究车用动力电池性能而言非常有意义.选取PNGV电池模型运用等效电路的思想来模拟电池的动态特性,并对电池模型参数的获取,介绍了Excel线性回归分析原理,在此基础上提出了基于最小二乘法,运用Excel电子表格中的相关统计函数来实现多元线性回归的方法来辨识电池模型参数,并说明了其方法的合理性.
The high efficient power battery is an important part in an alternative energy,and a reasonable model for the study of vehicle battery performance is very meaningful.The PNGV model uses an equivalent circuit to model dynamics characteristics of battery,and the parameters of the model are obtained.The linear regression analysis theory in Excel is introduced.Based on PNGV model,according to least squares regression,a multiple linear regression method based on relative statistical functions of Excel to identify parameters of model is put forward and the rationality of its method is illustrated..
