摘　　要：建立了铅酸蓄电池组的数学模型,采用对大容量铅酸蓄电池组进行突加扰动的试验方法,对不同容量的蓄电池组开展了实验研究,验证了所建模型并辨识出蓄电池组的参数。通过对不同状态的蓄电池组的参数辨识,发现其参数几乎不变。The mathematic model and parameter identification of high-capacity lead-acid storage battery are difficult to obtain for a long period. This paper deals with the experimental method of adding the disturbance suddenly for high-capacity lead-acid storage battery. The basic mathematic model and parameters of high-capacity lead-acid storage battery are obtained by measuring dynamic voltage and raising rate of current and steady values. The mathematic model is improved by analysing the surge process of initial current and voltage.
