[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.
