铅酸电池剩余放电时间预测模型与求解

Residual Discharge Time Prediction Model and Solution of Lead-acid Battery

为了准确预测铅酸电池剩余放电时间,将铅酸电池固定电流时放电过程划分为初期、中期和末期三个阶段。通过建立基于初等函数拟合的预测模型,借助MRE检验多种初等函数的拟合精度,同时对放电曲线进行整体拟合,采用计算机仿真求解得到铅酸电池剩余放电时间。仿真结果表明,该模型易于实现计算机编程,能准确预测剩余放电时间,具有推广价值。

In order to have an accurate prediction of the residual discharge time of lead-acid battery, the discharge process is divided into three stages： the initial stage, the middle stage and the end stage. For all discharge curves, a prediction model based on elementary function fitting is established in stages, the fitting accuracy of several elementary functions is tested by MRE, and the residual discharge time of lead-acid battery is calculated by computer simulation. The simulation result shows that this model is easy for programming, can have an accurate prediction of the residual discharge time, and has promotional values.
