Li-ion battery model
Loucký, Vojtěch ; Toman, Marek (referee) ; Cipín, Radoslav (advisor)
This diploma thesis deals with description of the principle of Li-ion cells, literature search on the topic of mathematical models of Li-ion cells and the creation of a selected mathematical model in MATLAB, which is able to simulate the course of voltage and state of charge as a function of time for different ambient conditions, such as various aging of battery .The creation of both the model and the procedure of identification of parameters necessary for the creation of the model are described here as well as different options of identification of parameters. The selected Thevenin model is then compared with the real course and the accuracy of the model is evaluated with respect to the measured course.

Dynamic Li-ion battery model
Loucký, Vojtěch ; Cipín, Radoslav (referee) ; Toman, Marek (advisor)
The main aim of this work is to compare mathematical models of Li-Ion batteries and for the chosen mathematical model create dynamic model in MATLAB. Different mathematical models are compared based on their weakness. There is detailed description of Improved Thevenin model, which is then created in Simulink and is tested for various discharging currents. This model is adjusted to work with parameters obtained from measuring data on real Li-ion cell and the results from simulations are compared with results from real measurements.
