Job Description

• During your internship you will conduct a literature review of classical electrochemical battery models, physics-informed neural networks, and hybrid modeling techniques applied to high-voltage EV traction batteries.
• You will investigate and compare methods of incorporating physical laws into neural networks, evaluating their strengths and weaknesses to provide a comprehensive overview.
• Furthermore, you will develop a hybrid model that integrates electrochemical physics-based models with data-driven methods to address limitations of common electrochemical models.
• You will implement the most promising physics-informed neural network approaches using Python and suitable deep learning frameworks. You will also train and calibrate the implemented models using laboratory and real-world battery telemetry data, performing hyper-parameter tuning and rigorous validation, including sensitivity analysis, to assess reliability and generalizability.
• Additionally, you will analyze and optimize model performance focusing on accuracy, robustness, and computational efficiency.
• Finally, you will compile research findings into a clear and concise internship report or master thesis, detailing the hybrid modeling approach, implemented models, and performance results.

Qualifications

• Education: Master studies in the field of Physics, (Electro-)Chemistry, Applied Mathematics, Computer Science, Electrical Engineering or comparable with good grades
• Experience and Knowledge: proficient in Python and MATLAB; familiar with deep learning frameworks (e.g. TensorFlow, PyTorch); knowledge in electrochemical battery models, machine learning, data analysis and computational modeling
• Personality and Working Practice: independent and analytical working style
• Enthusiasm: for Electromobility, Lithium-Ion Battery Technology and Programming
• Languages: very good in English
