Electric Mobility (Practical Course)

See TUMonline
Note: Since winter semester 2016/2017 the lecture Design of Electric Vehicles (hold by Prof. Lienkamp) is requirement for participating in the practical course. Participants are selected randomly, so the register date isn't considered. Registration takes place on TUMOnline. Please note that the registration is only possible for the waiting list - the selection of participants will be done by responsable staff. After your registration you will receive feedback on october, 12th indicating whether you can participate in the Praktikum. After that you will have to confirm your participation as the latest until october, 13th.

At the end of the module students are able to create the principal layout of an electric vehicle. This means they know which components are needed and how they have to be assembled functionally. After the course the students are able to understand the fundamental principles of the components needed in electric vehicles. Furthermore the students are able to apply the occupational and operational safety rules while working on electrical vehicles. After taking part in the course the students are able to apply an appropriate simulation-software to problems in the field of electric drive trains. At the end of the module students are able to analyze and evaluate questions in reference to charging and charging infrastructure.

The lab is introducing the students to the topic of electric mobility. The experiments are designed and arranged to teach the basic knowledge of the components existing in electric drive trains. In addition to the components used in electric drive trains knowledge about infrastructure and charging technologies will be imparted. The course shows problems in the range of electric mobility and is also introducing possible solutions. Furthermore, the course is also focussed on new problems coming up with the electrification of vehicles. During the course the topic of electric mobility will be discussed in general but the practical experiments are focused on the Quadrad (bike on four wheels) of the Institute and its components. That means that for measurements which have to be done at a real motor the students have use the Quadrad-motor.
Side by side to the practical experiments the students have to model the components of an electric drive train in SIMULINK. This should help the students to get a better understanding of the theoretical knowledge and the formulas to describe the components. With measurements at real components the students have to parameterize and verify their implemented models.
In the end, an entire vehicle model of the Quadrad is to be created consisting of the component models made in the previous lab lessons. With this entire vehicle model it is possible to simulate different vehicle configurations, driving cycles and control modes. As a final lab task the simulation results have to be compared with real measurement results measured with the Quadrad.

The lab plan:
- Basics and threat of high voltage
- Power electronics
- Electric motors
- Batteries and battery management
- Batteries: design, safety, package
- Charging and infrastructure
- Entire vehicle simulation and analysis
- Tractive resistance – the identification with the Quadrad
- Driving cycles - the measurement of the cycles with the Quadrad

Voraussetzung zur Anmeldung am Praktikum ist der Besuch der Vorlesung Auslegung von Elektrofahrzeugen des Lehrstuhls. Die Auswahl der Teilnehmer erfolgt durch PAS.

Each lab course lesson consists of one theoretical part and one supervised self-working part. During the theoretical part the students will be briefed in the theoretical background. During the following working part the students have to use the skills got from the supervision to implement simulation models in simulink or/and do practical experiments.

The final grade consists of two equal shares: one is an oral final exam (about 10 - 15 minutes for each student) and the other share is the average of all reworks done after each lab course.
