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 projects at Scania is an excellent way of making contacts and relations for your future working life. Several of today’s employees started their Scania career with a Thesis project. At Scania we are always looking for academic association with students and universities. If you as a student would like to work on this thesis or other than the one defined in this ad, you are encouraged to contact us as well.Background
The usage of power consuming devices has been proven to be of great value to the commercial vehicle industry. These devices are used in different systems, ranging from transmission and engine to USB outlets in truck cabins.
Power consuming devices have a short operating time. It has been found that their current consumption is different compared to traditional DC as it has transient characteristics. These transients originates from different sources - the power consuming device itself and conducted emissions from other similar devices.Target/scope
The transient currents complicate the answer to the straight forward question ‘how much power does the device consume?’ due to their frequency dependency. Therefore, the focus of this thesis is to quantify
the current consumption of power consuming devices. With emphasis being placed on the word quantify
, it is possible to break the term down into two general goals:
Description of the assignment
- Describe the power consuming device in the frequency domain
- Construct a viable and reliable test method for engineers to measure these transient currents in a specific frequency band.
Quantifying current consumption underlines the importance of the relation these power consuming devices have. In other words, the properties of the devices in the cable harness is crucial to understand. This gives Scania a comprehensive picture of the vehicle.
This thesis work is based upon typical engineering tasks that Scania employees work with. Therefore, this thesis is an opportunity for students to get first-hand experience of how to work with development at Scania. This allows students to apply theory learned from university lectures and labs to real issues in the commercial vehicle industry. These issues are not only solved through numbers, as teamwork and networking with different engineer groups is greatly encouraged at Scania.
The thesis work is mainly about analog and power electronics. Additionally, knowledge in electromagnetic compatibility is necessary. It is predicted that the thesis work will involve theory, simulation, practical lab work and vehicle measurements. Scania R&D in Södertälje has excellent testing ability with labs.
With that said, Scania wants to present this thesis work as an open-ended project and students are encouraged to give input to how the thesis goals can be improved.Education
Masters student with focus on electronics, engineering physics, applied mathematics or similar.
