30 credits – Vibration degradation on Li-ion battery cells

Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions.

Thesis project at Scania is an excellent way of making contacts for your future working life. Many of our current employees started their career with a thesis project.

Background:

Li-ion batteries are the most commonly used energy storage solution for electrified vehicles (hybrid or fully electric). This kind of application exposes the batteries to vibrations, such as road induced or engine induced ones, and the effects of this type of stress on the battery performance is not fully understood.

Most tests proposed by standards are based on extreme criteria for fail-pass and are unable to identify imminent problems and safety hazards.

Target:

The goal is to develop a test method/rig that simulates engine induced vibration as well as road induced vibration to verify the thus generated degradation of Li-ion batteries.

Assignment:

The candidate will work in collaboration with Scania R&D engineers in Södertälje. The work will include building a rig that simulates vibrations for real world applications, following our safety requirements, and study the effects of those vibrations on battery cell components.

Education:

M.Sc. student mechanical engineering

- experience with vibration

- interest in batteries and electrified vehicles

- good communications skills in English

Number of students: 1

Start date: January 2019

Estimated time needed: 6 Months
