摘要
对某容量为700Ah的动力蓄电池进行了12小时放电制恒流放电实验。根据实验采集的数据,应用灰色系统理论建模方法,建立了该型蓄电池恒流放电数学模型。在MATLAB环境下,采用该模型对蓄电池放电过程中的电解液密度的动态变化进行了模拟仿真,并结合实测值进行了必要的精度检验。经验证,模型结构简单、模拟仿真精度高并易于计算机实现。
12 hours constant current discharge experiments were carried on a power battery with capacity of 700Ah. According to the experimental data, constant current discharge mathematical model of this battery was set up with method of grey system theory. In MATLAB environment, the density＇ s dynamic change of the battery＇ s electrolyte was simulated using this mathematical model and the compute accuracy was tested by the measured data drawn from experiments. After verification, this model has the character of structure simple, high precision and is easy to computer simulation.
