Characterization and Modeling of NiZn and Li-based Batteries

Bhandari, Sarita

Abstract Details

2012, Master of Science, University of Akron, Electrical Engineering.
Battery modeling helps to understand the battery behavior, as it adds a bridge between the chemical and the electrical worlds. The aim of this thesis is to study the characteristics of the battery and suggest models that can approximate the voltage profile curve and the energy characteristic curve of different battery chemistries. In order to achieve this goal, batteries of different chemistries are monitored throughout their lifetime and the role of all the identified parameters on battery performance are observed. An observation is made that a cell operates in both linear and nonlinear regions, and the models of these regions are split accordingly. An electric circuit model is suggested to represent all the battery dynamics for the linear region. In addition, a mathematical model is used to represent the cell behavior in the nonlinear region. This thesis also focuses on determining the best mathematical model to represent the energy characteristic curve for different chemistry cells. Simulation results obtained by using the electric circuit model and the energy characteristic curve model are validated with the experimental results for NiZn cells and Li-based cells. Further, the models are validated by performing some error calculations, and confirming that the error is below the tolerable level.
