Internship or Master thesis in Embedded Battery State Estimation (m/f/d)

COMPLEX CHALLENGES. SMARTER SYSTEMS.

Modern battery systems rely on intelligent algorithms to understand their internal state and make the best use of the available energy.
As an intern or thesis student in Hilti’s Battery research team, you will contribute to the development of battery state-estimation and embedded algorithms. You will work with battery measurement data, develop and evaluate modelling and estimation approaches, and investigate how promising algorithms can be transferred toward embedded applications.
The internship combines data analysis, modelling, algorithm development and practical implementation, giving you the opportunity to work on a real engineering challenge from initial concept to prototype.
As part of our battery research team, you will work in an innovative and collaborative environment alongside engineers and researchers with different technical backgrounds. The Battery research team works across a broad range of battery technology topics, giving you the opportunity to gain insights beyond your individual internship or thesis project and to understand how different disciplines come together in the development of future battery systems.
The role is a full-time internship or Master thesis position and will be available from January 2027.

What You'll do

Depending on your background and interests, your tasks may include:

• Analyze and interpret battery measurement and test data
• Develop and evaluate algorithms for battery state estimation using MATLAB/Simulink and/or Python
• Investigate methods for improving algorithm accuracy, robustness and adaptability
• Compare different modelling and estimation approaches
• Support the implementation and verification of algorithms through embedded coding and testing
• Evaluate algorithm performance under different operating conditions
• Document, visualize and communicate your results within an interdisciplinary team

What You’ll Bring

You are currently conducting Master’s Studies in Electrical Engineering, Engineering Physics, Computer Science, Mechatronics, Control Engineering, Applied Mathematics, or a related field.
You have an interest in batteries, algorithms, modelling and embedded systems and experience with at least one technical programming environment, such as:

• MATLAB/Simulink
• Python
• C/C++

Ideally, your studies or previous projects have given you a good foundation in one or more of the following:

• Data analysis
• Control systems
• Signal processing
• Battery modelling
• State estimation

Most importantly, you enjoy solving technical problems in a structured and analytical way and are motivated to work with experimental data and learn more about battery technology. You are curious, enjoy developing your own ideas and are comfortable sharing your results and working collaboratively in an interdisciplinary environment.
