At Siemens, SSP interns get access to an international student network and community, career development opportunities with professional growth pathways, comprehensive practical training throughout the program, access to the Siemens Learning Hub and other training materials, and the opportunity to collaborate on exciting projects within a global, diverse team. Internship topic: Advanced modeling and testing of lithium-ion battery cells. What you'll be doing In collaboration with the Physics team of Simcenter Amesim and the research institute IFPEN, you will contribute to a joint industrial-research project focused on the modeling and experimental characterization of lithium-ion battery cells. These cells are at the heart of electric vehicles and energy storage systems, and accurate modeling is vital for building reliable digital twins that support design, control, and safety strategies. Your work will involve both experimental and theoretical aspects, including:
- Participating in test campaigns on lithium-ion cells under various operating conditions
- Analyzing electrical and thermal behavior based on experimental data
- Supporting the calibration and validation of battery models used in digital twin applications
- Exploring modeling strategies to improve the representation of key physical phenomena
- Collaborating closely with both industrial and academic mentors throughout the internship

The objective is to validate existing modeling and testing methods on state-of-the-art battery cells and work with your tutors to identify potential areas for improvement. This 6-month internship is based in Lyon (69), France and is available from January 2026. All about you! You are pursuing higher education in engineering (Bac +5 or equivalent) with a focus on energy systems, electrical engineering, thermal sciences, or physical modeling, in France.
- You have a strong interest in battery technologies, digital twins, and sustainable mobility.
- You are comfortable working with data analysis tools (e.g., Python, Excel) and have a solid foundation in physical modeling.
- You are motivated to work in a multidisciplinary environment, bridging industry and research.
