Modeling and Simulation Performance of Discharge Battery

Abstract
Estimation of the parameters of a battery is the main objective for all researches which focus on storage energy, which consist a part to develop a performance algorithm designed to suit the state of charge (SOC) which have to be accurate and able to adopt the equivalent circuit with its dynamic behaviour. In this paper, we propose a mathematical model to estimate the value of the battery parameters under discharge test, and test the obtained parameters through Matlab/Simulink tool, comparing the real data with estimated identify all the parameters of the battery, which guide us to estimate the working zone, we also performed that new design to fit the real measurement. A lead acid battery is tested by specific standard tests. Keywords- state of charge, battery parameters, battery equivalent circuit.
