Two-dimensional Modeling and Analysis of Lithium-ion Cell for Electric Vehicle Application

The process of modelling a device is dependent on the details one intends to derive from the model. In the context of energy storage devices in general and lithium-ion cell in particular; two-dimensional modelling provides meaningful insights into the cell’s electrical observables and their time dependencies. These observables and their time-dependencies are crucial for development of energy storage management systems. The work presented herein, describes graphically, the functional electrical observables of the lithium-ion unit cell, and finally supplies the average state of charge variation with respect to time. In this simulation study, the state of charge manifests nearly 75% increase for the positive electrode during discharge time of forty-five minutes.
