The aim of BlueDot EVenture project and with it student Formula DTU team is to develop and nurture student activities at DTU related to the ongoing green transformation of the energy system into a sustainable, cost-effective and reliable energy system. As a part to the BlueDot EVenture project, DTU student have an opportunity to take part in prestige international engineering competitions related to eMobility. Currently 20+ students are taking part in designing and building student Formula electric race car (CAD illustrated in the Figure below) with aim to compete in Silverstone UK in July 2019.
In this project student will work on the design and development of 590Vdc battery energy storage used in the student Formula race-car. The primary goal of the project is to design the accumulator storage of approx. 6 kWh which is in compliance with the rules and regulations of FSUK and FSG and is further more optimized to maximize the system efficiency during the race events.
The student will review suitable chemistry of the cells and define the proper cells specification (Energy Capacity, C rating, max T…), evaluate the heat development in non-solder contacts in the battery modules and asses the cooling requirements, develop BMS interface, etc. Particular focus of this project will be electrical and thermal analysis of accumulator energy storage, mechanical integration of the developed solutions, all with experimental validation. The project will compare the benefits/ risks of high voltage (600V) standard vs. low voltage (120V) standard accumulators.
Tasks: Depending on the student’s ambitions, the project can consist from following steps
- Literature and market review of batteries, connecting methods, suitable materials
- Develop parametrized CAD model for battery terminals, temperature sensors, integration of fuses, relays, BMS….
- Evaluation of key performance indicators of battery operation
- Apply optimization to the interconnection of the battery cells in order to reduce losses and ensure compliance
- Construction and experimental validation of battery prototype
