Project Title: Design of a stationary energy storage concept for electric bus charging stations at depots and termini using second life batteries

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.

TUMCREATE is looking for a highly motivated student to conduct a master thesis or internship. TUMCREATE is a research platform in Singapore that is developing a 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. Opportunistic fast-charging for the buses leads to high fluctuations in power demand for large charging stations, as shown in the figure on the right. The fluctuations can be reduced by installing stationary energy storage, thereby reducing the costs of the power lines. The use of aged batteries could reduce the system costs further. 

Objective & Tasks
The student will be responsible for designing a stationary energy storage concept for electric bus depots and termini using second life batteries.  The thesis will build on the results from a previous study which evaluated the energy and power demand requirements for a city-scale electric bus operation. Based on the obtained demand requirements, the potential of installing stationary energy storage to achieve load leveling will be investigated. The tasks include but are not limited to: 

  • Literature research on the topics including stationary energy storage and 2nd life battery use cases
  • Determining the required size, power and components of the energy storage
  • Analysis of the economic potential of installing stationary energy storage at bus terminals in Singapore
  • Cost comparison between storage concepts consisting of 2nd life batteries, new batteries and supercapacitors
  • Developing a strategy for scaling the stationary storage with electric bus market penetration
  • 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 technology is preferred
  • Independent, self-motivated mindset
  • Fluency in English and able to work in a multicultural environment
