Nowadays, because of the many applications of batteries, modeling of this energy sources and accurate estimation of their behavior at different conditions is very important. In the traditional linear mathematical based models of batteries, nonlinear behavior of them and the variation of battery voltage during charge and discharge states are neglected. But various nonlinear physical, chemical an...

A piecewise linear, time-varying model for modeling the charging and discharging processes of Li-ion batteries is introduced in this paper. Such a model consists of a group of piecewise linear model segments, whose parameters are adapted online over time. Thus, the combined overall model is capable of modeling nonlinear time-varying processes, such as a Li-ion battery charging and discharging p...

This paper reports a modeling methodology to predict the effects on the discharge behavior of the cathode composition of a lithium iron phosphate (LFP) battery cell comprising a LFP cathode, a lithium metal anode, and an organic electrolyte. A one-dimensional model based on a finite element method is presented to calculate the cell voltage change of a LFP battery cell during galvanostatic disch...

This thesis deals with the design of a battery cell testing platform and Lithi...

Electric-drive vehicles (EDVs) have drawn more and more attention worldwide. As one of the most important parts of EDVs, battery management systems (BMSs) manage the huge amount of battery cells in EDVs and assures their safety. To achieve these goals, re‐ searches in BMS, such as battery modeling, battery state estimation, and battery balanc‐ ing have gained a new vigor. This chapter will revi...

Modeling of the battery for 42V PowerNet system is presented. For the Battery Management System (BMS) algorithm in a Mild hybrid vehicle, accuracy in the battery model is crucial. The battery model is needed for the BMS algorithm as well as for the system computer simulation for the energy management. The battery model was composed of impedance elements and each element of the model is estimate...

It is necessary to form an energy system in order to deliver the electrical power to a region that delivering energy to them from the national grid is not possible. At the moment, using the hybrid renewable energy systems (HRES) is the suggestion of more articles and scientific books because of environmental problems, nearing to the end of fossil fuels, and challenges including unpredictability...
