Abstract

The recent trend of performance increase in the smart mobile devices demands more power consumption and lower batter life time. Amongthree battery models of mathematical model, electrochemical model and electric model, the Thevenin``s equivalent circuit with non-linearfunction model of SOC in the electrical model is widely used. However, the OCV results have only limited accuracy because of thecharacteristic shift caused by temperature and age and atypical impedance property that cannot expressed by electrical components. In thispaper, the new battery model that improves the accuracy of the existing models is proposed. In the proposed simulator the mathematical modelfor SOC characteristic is improved and the adjustment for the temperature, the age of battery and atypical electrical characteristics. In theexperimental results of predicting of the battery in the static and dynamic state, the proposed simulator shows improved MSE comparingto the results of the existing methods.
