Overview

Recently, Kalman filtering has been proposed for cell modeling in [1,2,3]. Highly promising and relevant results are shown for closely modeling the cell terminal voltage under load using the cell current as input. Furthermore, they add temperature dependence to the models and provide results where the state-of-charge (SOC) is estimated without correct initialization, i.e., the SOC is not exactly known at the beginning of operation of the cell.

The task of this thesis is to implement the models in [2,3] and to reproduce the results using data from a local company.

Profile of prospective student

The candidate should be interested in machine learning, applied mathematics/statistics, Matlab programming, and algorithms. Interested candidates are encouraged to ask for further information.
