摘　　要：首先通过大量实验测试,对处于不同电池荷电状态(SOC)下铅酸电池的等效模型参数进行了辨识,使传统的恒定参数电池模型得以改善。建立了基于数字信号处理和控制系统(dSPACE)的SOC估算测试平台,以dSPACE充当快速控制原型对铅酸电池进行SOC实时估计。此处给出了详细的SOC估计算法,以及基于dSPACE试验平台的开发流程,并进行了一系列半实物实验测试,取得了较满意的实验结果。Euivalent model parameters of valve regulated lead-acid battery under different state of charge（SOC） are iden-tified through massive experimental tests,so the battery model with constant parameter is improved.Then,a SOC test platform based on digital signal processing and control engineering（dSPACE） is established,and battery SOC is es-timated in real time using dSPACE as a rapid control prototype（RCP）.The SOC estimation algorithm is given clearly,development process of the platform is described,a series of semi-physical simulation tests are conducted and the re-sults tend to be satisfactory.
