The thesis project deals with an intelligent battery system and its thermal behavior. A cooperation between the Technical University of Munich (TUM) and the Company Knorr-Bremse (KB) in Hungary developed the idea to use open source software for this modeling and coupled simulation of a thermal and electrochemical system. A simulation model for a single battery cell is developed, and an investigation regarding off-the-shelf software is also included. The developed model considers electronic and thermal properties of the battery cell and spatially discretized temperature fields at the boundary surfaces of the cell as boundary conditions. It is based on experimental data, and the three-dimensional discretization of the domains for electrostatic and thermal simulations is realized using the finite element method (FEM)-software FEniCS. Both the electrostatic and thermal simulation are coupled using the open-source coupling library preCICE. Due to technical limitations and restricted time, the project so far is limited to the simulation of a single battery cell. This thesis describes the task and different views on this project (chapter 1.4), as well as the progress in the simulation task itself in chapter 2 and 3. Chapter 4.1 explains the results and limitations of the project, chapter 4.3 summarizes the work and describes outcomes for TUM, KB. Chapter 4.2 describes how the project could proceed in the future.     «
