A dynamic mathematical model of lithum - ion battery in Matlab/Simulink

摘要

In this paper, we are interested to the dynamic modeling of lithium-ion battery behavior as the mathematical modeling of the battery is essential for a better understanding of the characteristics, the performance evaluation and therefore battery sizing and optimization. The dynamic model is a phenomenological model based on an equivalent circuit model. In order to investigate the electrical output characteristics of the concerned lithium-ion battery and validate the conceived model, the presented model is implemented in MATLAB/Simulink. Dynamic simulations are carried out, including the observation of the changes in battery terminal output voltage under different charging/discharging modes and cycling conditions. The simulation results are compared with the results obtained from several recent studies and to manufacturer data.
