摘要
以2016年全国大学生数学建模竞赛C题"电池剩余放电时间预测"为例,通过对给出的铅酸电池采样数据进行分析,得到了各电流强度下的放电曲线,并建立了20A到100A之间任一恒定电流强度放电时的放电曲线的数学模型.最后构建了多元二项式回归模型,预测出电池在指定衰减状态下的剩余放电时间.
Based on the problem C(prediction of battery residual discharge time)of2016China Undergraduate Mathematical Contest in Modeling,the discharge curves under different current intensities are given by the analysis of the sampling data of the lead acid battery,and the mathematical model of discharge curve at any constant intensity from20A to100A is established.Finally,a multivariate binomial regression model is constructed and the residual discharge time of the battery in the specified attenuation state is predicted.
