【摘要】：分析了安時計量法和電動勢法在線預(yù)測電池當前荷電量(SOC)的利弊,提出了在獨立光伏系統(tǒng)中采用電動勢法與安時計量法聯(lián)合的蓄電池容量在線預(yù)測的新方法。對影響安時計量法估算電池SOC精度的因素進行了修正,建立了適合一般獨立光伏系統(tǒng)的實用電動勢預(yù)測模型,提取了電池E-SOC關(guān)系曲線,將基于電動勢預(yù)測模型的電動勢法與經(jīng)過修正的安時計量法通過一種并聯(lián)加權(quán)的結(jié)構(gòu)進行結(jié)合,實現(xiàn)了優(yōu)勢互補,完成了對電池SOC更加準確的估算。實驗結(jié)果表明,該蓄電池SOC預(yù)測方法簡單易行,實時性強,精度高,應(yīng)用前景良好。
[Abstract]:This paper analyzes the advantages and disadvantages of ammeter and electromotive force (EMF) in on-line prediction of current charge (SOC) of batteries, and puts forward a new method of on-line prediction of battery capacity using electromotive force and amperometric method in independent photovoltaic system. The factors that affect the accuracy of SOC estimation by amperometric method are modified, and a practical EMF prediction model suitable for general independent photovoltaic system is established, and the E-SOC relation curve of the battery is extracted. The electromotive force method based on electromotive force prediction model and the modified amperometric method are combined through a parallel weighted structure to realize complementary advantages and more accurate estimation of battery SOC. The experimental results show that the SOC prediction method is simple, real-time, high precision and good application prospect.
