ETDs

This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries.

In this thesis, an issue is post at the beginning, that there is limited experience in connecting a battery analytical model with a battery circuit model. Then it describes the process of creating a new battery circuit model which is referred to as the kinetic battery model. During this process, a new general equation is derived. The original equation in the kinetic battery model is only valid at a constant current rate, while the new equation can be used for not only constant current but also linear or nonlinear current. Following the new equation, a circuit representation is built based on the kinetic battery model. Then, by matching the two sets of differential equations of the two models together, the ability to connect the analytical model with the battery circuit model is found. To verify the new battery circuit model is built correctly, the new circuit model is implemented into PSpice simulation software to test the charging performance with constant current, and Matlab/Simulink is also employed to simulate a realistic battery charging process with two-stage charging method. The results have shown the new circuit model is available to be used in realistic scenarios. And because the kinetic battery model can describe different types of rechargeable batteries, the new circuit model is also capable to be used for various battery types.
