基于谐振法和数学模型的电解液密度检测技术

Technology of Electrolyte Density Measurement Based on Mathematics Model and Syntony

电解液密度是直接反映蓄电池充放电状态和电池容量的重要参数,但难以进行准确、简便和经济的在线自动测量。因此,对基于谐振法和数学模型的混合检测方法进行了深入研究,建立了基于谐振法监测数据的密度测算数学模型,并给出了数学递推算法,试验表明该检测方法可靠、有效,且工程适用性良好。

The electrolyte density is an important parameter that directly reflects the charge-discharge characteristics and the capacity of the storage battery. It is difficult to measure the parameter on-line accurately, simply and economically. A hybrid measurement based on mathematics model and syntony was investigated, and a new recursive algorithm was introduced. Experiment result shows that the scheme is effective and available for engineering application.
