Research on lead-acid battery impedance parameters identification system based on LabVIEW

基于LabVIEW对铅酸蓄电池的阻抗参数辨识系统进行了研究,在对铅酸蓄电池阻抗进行全面分析的基础上,提出了系统设计的总体方案以及软件和硬件的具体设计;同时提出了由虚拟仪器实现变频交流恒流源的方法,实现了铅酸蓄电池阻抗参数的在线实时辨识,具有重要的实际意义和推广价值。

The impedance parameter identification system for lead-acid battery based on LabVIEW was studied in this paper. The general scheme and the specific design of software ＆ hardware were proposed based on the integrated analysis of lead-acid battery impedance. And meanwhile, a method to realize the frequency conversion AC constant current source by visual instrument was presented, which has achieved the online and real time identification of lead-acid battery impedance parameters. Therefore, this method has a high practical value and is worth of popularizing.
