Abstract

A brief overview of the various equivalent battery models will be reviewed, a model will be decided upon in which it will be used to depict internal characteristics of the battery. These characteristics will be correlated to the state of charge of the battery. In this paper, a review of how to obtain the internal parametric of the alkaline batteries will be explained utilizing electrical spectroscopy with the data analyzed by various techniques. Techniques that will be looked into are; Least-Squares fitting, Delta V/Delta I, as well as open circuit voltage correlation to state of charge.
