Abstract
Nowadays, Lithium-ion batteries are as the most preferable technology for consumer electronics. They found their way also to electric vehicles or even satellites, mainly due to their high energy density and long life. In the applications, the batteries require a battery management system for safe and optimal operation. Often, state estimation functionalities (as state-of-charge or state-of-health) require a running battery model. Therefore, an electrical circuit model (ECM) that accurately captures a battery behavior in suitable complexity is needed. This paper presents a three steps parametrization technique of ECM for Lithium-ion batteries based on laboratory experiments. Furthermore, an analysis of SOC and temperature dependence of battery parameters has been conducted. The developed ECM is validated, and its accuracy is evaluated by Root Mean Square Error (RMSE) and Maximal Absolute Error (MaE).
