Systems

HIU scientists in the Systems research field test and characterize the electrical properties of commercial battery cells, e.g. to evaluate aging processes in a battery in a holistic and system-oriented manner. In this way they lay the foundations for further optimization of the batteries.

Research Field

The focus is on the life cycle of commercially available cells (e.g. with newly developed cell chemistry) and their evaluation with regard to potential fields of application. Main topics are e.g. the determination of performance indicators, charge cycle stability or the state of charge. By comparing the battery properties with the specific requirements of the different fields of application, the suitability of materials and battery systems for use in stationary energy storage devices or in electric vehicles is assessed.

In addition, life cycle assessments (LCA) are created for the new materials in order to enable a holistic characterization of future products at an early stage. This means that aspects such as toxicity, availability of raw materials or recyclability can already be included in battery development.
