About TUMCREATE
TUMCREATE is a research platform for the improvement of Singapore's public transportation, including the deployment of electric and autonomous mobility. Researchers from Technical University Munich and Nanyang Technological University join forces and are funded by Singapore’s National Research Foundation as part of the Campus for Research Excellence and Technological Enterprise (CREATE).

In TUMCREATE, over 100 scientists, researchers and engineers work together, led by Professors from the Technical University of Munich and Nanyang Technological University. The Mission of TUMCREATE is to seek the ultimate public transport system for the people of Singapore. Our innovative road transport solutions will provide high comfort and a positive travel experience, best protection of the environment and maximum benefit to the society and the economy.
 

Background

TUMCREATE is looking for a highly motivated student to conduct a master thesis or internship. TUMCREATE is a research platform in Singapore developing an autonomous public transport system for the year 2030. The system concept consists of small electric autonomous buses that can form platoons and respond dynamically to vehicle demand. Public buses are well suited for electrification due to their limited operating range and the predictability of their driving patterns. However, the electric powertrain is more sensitive to high and low temperatures and therefore requires a well-designed thermal system. The optimal thermal system design is investigated as part of a larger optimization tool that finds the optimal bus powertrain configuration for a specific use case, see figure.  
 

Objective and Tasks

The student will be responsible for the development of an optimization method that finds the optimal battery thermal system design. The student can build on previous work in which a method was developed to find the optimal battery size, number of chargers and charger power for a specific use case. The tasks include but are not limited to:

• Literature research on battery thermal design, battery modelling & thermal modelling

• Identification of key parameters of the thermal system • Optimization of thermal system parameter

• Analysis of the impact of preheating/precooling

• Implementation in different use cases, e.g. different ambient temperatures and opportunity charging vs. overnight charging

• Integration in existing optimization tool

• High quality documentation in the form of a report or a thesis (if applying as a master thesis student) 
 

What we expect from you

• Initial experience with battery simulation is preferred

• Independent, self-motivated mindset

• Fluency in English and able to work in a multicultural environment
 

What we offer you

• Interesting innovative research topic

• Opportunity to be part of a scientific publication

• Financial support

• An international and multidisciplinary environment

• A great experience in one of the most dynamic megacities in Asia
