Accurate circuit model for steady-state and dynamic performance of Lead-Acid AGM batteries

Electrochemical batteries are rapidly gaining wide-spread application in transportation systems as well as in the electric utility sector, and accurate battery models are need during the design stage of such systems to forecast future performance. This paper proposes a simple and yet accurate model of a sealed AGM battery. The model takes into account the nonlinear characteristics of the discharge curves, and its parameters are derived by using the manufacturer's data sheet in addition to a simple laboratory test on a 12 V, 89 Ah battery. Comparison between the measured and calculated responses to a number of different discharge profiles shows a comfortable degree of accuracy of the proposed battery model.
