Abstract

Modeling the external characteristics of the battery precisely is a basic issue for effective battery management in energy storage systems. It is difficult because many inherent factors influence the external characteristics, but only few information, such as terminal voltage, current and surface temperature, can be obtained for modeling. This paper proposes a simple method for modeling the discharge characteristics of the battery. The basic patterns of discharge curves and their relationship with discharge current are analyzed. A mathematic model is built based on the method .The model is verified with experiments on valve-regulated lead-acid (VRLA) batteries.
