MODALIS2 – Role of Siemens Technology (SAGCT)

Interview with Michael Fischer

Development Engineer for Battery Applications and Manufacturing at Siemens Technology.




What is the expertise of SAGCT?

Siemens Technology (SAGCT) is the central research and development unit of the Siemens AG and contributes to the innovation of its different business units. SAGCT comprises different technology fields, including topics related to batteries. This field has a strong history in the characterization and modelling of different types of batteries, as well as knowledge of engineering and application of battery systems.


Which role does SAGCT have in MODALIS2 and what are your specific tasks?

SAGCT is performing several short- and long-term measurements on Gen 3 and Gen 4 cells, providing electrical, thermal and dilatometry data. The measurement data are used to characterize cells and components, serving as input for the modelling and simulation of these cells. Additionally, tests are performed to validate simulated predictions against actual cell behavior under various operating conditions.


Which challenges are you facing in the project?

Ensuring defined handling, storage and test conditions is essential to obtain data that accurately reflects the characteristics of the measured cells. Selecting an appropriate test plan is another important factor to draw relevant conclusions from measurement data. Within this project, new test setups had to be implemented to allow the simultaneous acquisition of electrical, thermal and dilatometry data, affording a more detailed understanding of the cell’s behavior.


Which benefits derive from the project for SAGCT?

First of all, SAGCT benefits from a strong collaboration and knowledge sharing with its academic and industrial partners in this project.

Secondly, a fundamental understanding of Gen 3 and Gen 4 cells is important to estimate the performance and possible limitations of these battery technologies.

Lastly, assessing the capabilities of the employed simulation tools provides guidance on how these methods can benefit future developments in the field of energy storage technologies.
