Master Thesis: Create thermal models for use in batteries

Take the opportunity to write your master thesis with our engaged team!

Background:
The industry is going through big changes and Atlas Copco Industrial Technique works closely with customers in this transformation. Together we are developing high-quality software and hardware used by customers worldwide. You are most likely using our customers’ products daily. 

During your thesis you will be part of a cross functional team responsible for batteries and chargers. You will be supported by the Engineering team, with expertise in electronics, mechanics, software, and testing. The team is responsible for both existing battery- and charger products and the development of new product and solutions. 

Target
The aim of this master thesis is to develop and evaluate thermal models for small batteries used for handheld tools. Examples of objects to monitor are e.g., cells, mosfets, fuses and PCB.

When using a battery, certain components need to stay within temperature limits. It is very good not only to keep a fixed limit, but also to see if the value is reasonable considering the power going in and out of the battery. So, we want to compare the measured value to a calculated value, this calculated value is determined with help of thermal models. Hence, temperatures should not only stay within limits, but they should also harmonize with the models.

Definition of scope
•    Develop thermal models and compare the result against reality and simulations.
•    See if the model can be executed on a smaller CPU without floating point hardware.
•    Implement and verify on real batteries provided by Atlas-Copco.

Your profile:
We are looking for a master thesis student with experience and/or interest in the following:
•    Thermal modelling
•    Programming
•    Mechanical engineering/ mechatronics
•    Sensors

Start date mid-January 2023.

For further information
Please contact Therese Sennerfors (team manager) or Nicholas Sävenlid (thesis supervisor) for more information. We only have the possibility to handle applications received through our website. Applications will be reviewed continuously.
