2026年4月24日

We are seeking a highly motivated PhD student to join a research project at the forefront of battery diagnostics and modelling, that will help shape the future of battery technology by developing methods that reveal what is happening inside batteries in real time.

Your work assignments

The project develops next-generation methods for understanding and predicting lithium-ion battery behaviour using dynamic Electrochemical Impedance Spectroscopy (EIS), combining advanced measurement technology with modelling and data-driven analysis. A key component is a novel measurement approach that enables high-resolution data to be collected continuously during real operating conditions, providing unprecedented insight into battery dynamics and degradation.

The PhD student will develop models and diagnostic methods that translate this data into meaningful indicators of battery health, performance, and lifetime. The work combines physics-based modelling with data-driven approaches, with the goal of enabling accurate and actionable battery diagnostics.

The project is carried out in close collaboration with leading industrial partners, including Husqvarna Group and Toyota Material Handling Europe, together with the technology developer Batixt and an international research partner at Sungkyunkwan University in South Korea. This provides a unique opportunity to validate methods on real systems and data from production, operation, and second-life applications, ensuring both scientific impact and industrial relevance.

As a PhD student, you devote most of your time to doctoral studies and the research projects of which you are part. Your work may also include teaching or other departmental duties, up to a maximum of 20 per cent of full-time.

Your qualifications

You have graduated at Master’s level in computer science, mechatronics, electrical engineering, engineering physics, applied mathematics, or a related field, or completed courses with a minimum of 240 credits, at least 60 of which must be in advanced courses in areas previously mentioned. Alternatively, you have gained essentially corresponding knowledge in another way.

You work systematically, collaborate well, and tackle challenges with persistence and creativity. In addition, you need to have a genuine interest in high-quality research and possess strong analytical skills with a scientific approach. As our activities are conducted in an international environment, you must have the ability to communicate in English, both orally and in writing. Basic knowledge of spoken and written Swedish is an advantage, or a willingness to learn Swedish in parallel with your assignment.

The position is particularly suitable for candidates with strong skills in applied mathematics, control, physics, or electrical engineering, and an interest in dynamic systems and modelling. Experience in system identification, optimization, or numerical methods is valuable, as is knowledge of data analysis and machine learning for complex, high-dimensional systems. Programming experience in MATLAB or Python, and an ability to connect theory with experimental data, are strong assets.

Your workplace

As a PhD student at the Division of Vehicular Systems, you will become part of an international research environment with strong ties to industry. The division conducts research as well as undergraduate and postgraduate education in areas such as autonomous systems, electrification, battery systems, advanced diagnostics and prognostics, and modelling and control of vehicle functions.

Through a close integration of theory and practical applications – often in collaboration with industrial partners – the division offers excellent conditions for research of high scientific quality with clear industrial relevance.

The employment

When taking up the post, you will be admitted to the program for doctoral studies. More information about the doctoral studies at each faculty is available at Doctoral studies at Linköping University.

The employment has a duration of normally four years’ full-time equivalent. Extension of employment up to five years is based on the degree of teaching and institutional assignment. Further extensions may be granted in exceptional circumstances. You will initially be employed for one year, after which your employment will be renewed for a maximum of two years at a time, depending on your progress through the study plan.
