Modeling and Simulation of Lithium-Ion Battery Considering the Effect of SOC and Temperature

The use of lithium-ion batteries (LIB) is common in portable devices, electric vehicles, and aerospace applications thanks to their considerable amount of energy density, compact size, as well as the low maintenance costs. These advantages make them a key technology in promoting sustain ability and combating climate change. A reliable lithium-ion battery (LIB) model is essential for accurately estimating key parameters such as voltage and state of charge. Developing an efficient and precise battery models are considered vital, as they account for various influencing factors. A battery model was developed in this study, using MATLAB/Simulink, focusing on the effects of temperature and SOC. The model is explained, developed, and validated against experimental data, measuring voltage, SOC, and current under varying temperature conditions. Although this model currently considers only SOC and temperature, it can be extended to include additional factors.
