Estimation of Capacity of Lead Acid Battery Using RBF Model

Abstract

Analytical models have been developed to diminish test procedures for product realization, but they have only been partially successful in consistently predicting the performance of battery systems. The complex set of interacting plrysical and chemical processes within battery systems have made the development of analytical models to be a significant challenge. Advanced simulation tools are needed to become more aecurately model battery systems which will reduce the time and cost required for product realization. As an akernative approach, we have begun development of cell performance modeling using non-phenomenological models for battery systems based on Radial Basis Function which uses Matlab 7.6.0(R2008b). A Radial Basis Function based learning system method has been proposed for estimation of capacity of lead acid battery. Radial basis function based technique is used for learning battery performance variation with time, temperature and load. Thus a precision model of Radial Basis Function has been evaluated. The correlation coefficient of this model is worth 0.99977 shows good results for the target cnd network output.
