hela Sverige Within the Electromobility department, we work with the design and development of electromobility systems and components such as energy storage, motor drives, and charging solutions for Volvo group products. Electromobility is an important technology area with a strong contribution to reducing the CO2 emissions in our society
Reaction-induced heat generation inside the cells of a battery is a major issue reducing
battery performance, capacity, power, and the overall system safety. Heat and mass
transfer concur within cell materials to trigger an escalation of exothermic reactions and a
severe increase in the temperature, which can lead to catastrophic failures of the battery
cell. Such a phenomenon, called thermal runaway (TR), poses serious safety problems:
smoke, fire and explosion are TR-induced problems.
Suitable background
We are looking for students from Mechanical engineering, Chemical engineering, Engineering Physics, or any other relevant engineering program and are at the end of finalizing their master's degree. You have a structured approach and an interest in virtual development. Knowledge in Computational Fluid Dynamics and Lithium-Ion battery is meritorious, and your English is fluent.
Qualifications:
MSc Engineering student in applied physics, mechanics or similar. Ready for thesis work 2023.
Education in direction towards fluid dynamics or mechatronics.
Programming skills preferably Python is merit.
Pervious knowledge in GT-SUITE is merit.
Communication skills and ability to document a work process in steps.
Fluent in English, spoken and written
Having knowledge in Lithium-Ion battery and mass transport phenomena is a merit.
Description of thesis work
The master thesis project aims at formulating a new 1D model of thermal runaway propagation
which comprises the coupled heat-mass transfer effect, from the chemical
chain reaction mechanisms, to the heat and mass generation and propagation inside and
outside a cell structure. The model is calibrated with experimental data at Volvo Trucks.
The final goal is to provide a more reliable tool to anticipate and predict the failure mechanisms
in a battery cell and minimize the negative effects at the battery-module level.
