As the need for better prediction of battery life parameters in secondary batteries evolves, especially for electric vehicles, many researchers have looked for methods beyond simple battery modeling. One of the promising methods is electrochemical impedance spectroscopy. This is typically a technique used to get insight on the kinetic reactions in batteries and various studies have shown excellent...
One of the most relevant tasks that must be carried out by a Battery Management System (BMS) is the diagnosis of the battery state. An important part of the algorithms used for determining the State of Charge (SOC) or the State of Health (SOH) requires a cell model to run. The most precise is the model used, the best is the estimation achieved by the algorithm. In this paper, two techniques for obtaining...
A brief overview of the various equivalent battery models will be reviewed, a model will be decided upon in which it will be used to depict internal characteristics of the battery. These characteristics will be correlated to the state of charge of the battery. In this paper, a review of how to obtain the internal parametric of the alkaline batteries will be explained utilizing electrical spectroscopy...
