Role Summary
We are offering a fully funded Industrial PhD position in collaboration with KTH Royal Institute of Technology, focused on developing battery ageing models for Battery Management Systems (BMS). This role combines academic research with practical application in a global industrial context, contributing to the advancement of electric mobility and energy storage.
This role is a part of TRATON Group R&D, located in Södertälje, Sweden.
About the Position
Are you driven by innovation, electrification, and advanced software systems? We are offering an exciting Industrial PhD opportunity in collaboration with KTH Royal Institute of Technology focused on Battery Management System (BMS) software development — a critical area in the future of electric mobility and energy storage.
As an Industrial PhD candidate, you will contribute to software solutions for next-generation BMS platforms, while gaining experience in both academia and real-world industry application.
The automotive industry develops advanced embedded software for monitoring and controlling the batteries in BEV vehicles. To maximize battery performance, the software heavily relies on models. One type of model that needs more understanding is ageing models. The aim of this doctoral project is to use vehicle and test data to develop models that predict ageing of battery cells built into a battery system. An expected outcome is that the models can contribute to longer battery lifetime by serving as input for design improvements, improvements in existing algorithms, as well as an understanding of how vehicle usage influences the lifetime.
The results of the project are expected to be published in scientific journals and presented at national and international conferences as well as within TRATON.
You will be employed by TRATON, while the academic position at KTH will provide the opportunity for professional development through studies towards a PhD degree. The goal is to complete doctoral education up to an obtained doctoral degree.
The work will be done in close collaboration with KTH, Division of Decision and Control. The main supervisor will be Professor Jonas Mårtensson, KTH and co-supervisor is Björn Bökelund, TRATON. The main workplace will be at Scania in Södertälje.
