[updated 05.06.2025]
Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

WIBASc-525-625-Ing29 Industrial Engineering, Bachelor, ASPO 01.10.2013 , semester 5, optional course

Suitable for exchange students (learning agreement)
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
30 class hours (= 22.5 clock hours) over a 15-week period.
The total student study time is 90 hours (equivalent to 3 ECTS credits).
There are therefore 67.5 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
WIBASc145 Physics
WIBASc435 Thermodynamics
WIBASc445 Electrical Engineering

Learning outcomes:
After successfully completing this module, students will have a basic understanding of the physical principles and system technology of battery storage systems. Topics such as material selection, electrochemistry, and thermodynamics will be covered. Students will also learn about methods for modeling and simulating battery cells in relation to electrolyte movement, charging, and discharging. The lecture will cover current applications such as battery systems for electric mobility and smartphones. These include lithium iron phosphate (LFP) and lithium nickel cobalt manganese (NCM) batteries, as well as novel cobalt-free batteries (NMX). The production processes and quality assurance measures used in manufacturing will be described.

Module content:
And special battery designs in the familiar prismatic, cylindrical, and pouch shapes will be discussed.
 
Module content:
 - Electrochemistry and thermodynamics
 - Materials and heat transfer processes
 - Thermal management and thermal behavior of batteries
 - Possible power losses, wear and tear and possible defects
 - Battery integration, applications and designing for vehicle applications
 - Charging and discharging behavior (Butler-Volmer equation) and SOC (state-of-charge)
 - Battery monitoring, battery management and battery characterization
 - Stationary applications and material issues
 - Production process and quality management
 
Students will get to know the user-friendly simulation tool Matlab/Simulink based on a diffusion problem and a battery model. (Easy to use; no prior knowledge is necessary.) The resulting technical solutions, as well as possible design alternatives, will be discussed in the group and presented in a project.

[updated 05.06.2025]
Teaching methods/Media:
The module will be held in hybrid lecture/tutorial format. In the course of the module, students will work independently in teams on the design of a battery storage system. To this end, each team will perform simulation calculations using the battery model and document the results in a project report. Students should be able to apply the subject matter independently to their own battery designs.
 
After successfully completing this course, students will:
 - be able to carry out discussions in small groups and develop a solution
 - be able to independently define tasks, build up the necessary knowledge, and implement it
 - be proficient in the Matlab/Simulink software tool commonly used in industry
 - be able to take responsibility within the team and discuss problems with experts.
 
Professional and methodological skills 60%, Social skills 15%, Personal competence 25%
 
A battery cell will be examined in detail in a project involving various teams using the Matlab/Simulink software tool. Students will take an exam at the end of the module.
