TUM Department of Electrical and Computer Engineering – Institute for Electrical Energy Storage Technology

The Institute of Electrical Energy Storage (EES) at the Technical University of Munich (TUM) was founded in May 2010 and focuses its research on both the mobile and the stationary applications of lithium-ion batteries. In recent years, it has established itself as an internationally recognized research group by virtue of numerous successful projects and publications. The institute has extensive expertise in the fields of cell modeling and simulation as well as in the electrical, thermal and mechanical characterization of lithium-ion batteries. Furthermore, the aging and efficiency of various energy storage system applications are analysed.

In the research cluster Battery Utilization Concepts, EES is involved via the projects greenBattNutzung, SimBAS, BALd, MADAM4Life, NUBase and OSLiB. It thus actively contributes to all three topics (A: Safety & Performance, B: Aging & Lifetime Prediction, C: Battery System Assessment) – especially in the focus areas A2, A3, B2, B3 and C2. The institute adds to the competences of the research cluster with its relevant know-how in the experimental investigation and characterization of lithium-ion batteries as well as in the simulation of battery storage systems in various fields of application. Furthermore, the EES coordinates the projects OSLiB and SimBAS.

Institute of Automotive Technology

The Institute of Automotive Technology conducts research in the field of mobility, particularly electromobility as well as its components and infrastructure. For this purpose, the research is clustered into five research groups, focusing on individual topics in the field of mobility: Vehicle Dynamics, Driver Assistance and Control Systems, Vehicle Concepts, Electric Drive Systems and Smart Mobility.

The Electric Drive Systems research group investigates and optimizes the high-voltage battery, the power electronics and the electric motor as well as the interaction of the components in the electric drive train. Our expertise in the development of simulation models and prototypes supports the process from early design to vehicle deployment to increase the range, efficiency, and sustainability of electric vehicles.

The Institute of Automotive Technology is involved in two projects within the research cluster “Batterienutzungskonzepte”.

The project “BALd” aims to accelerate the aging characterization of lithium-ion batteries and the life prediction that can be derived from it. In this context, the FTM evaluates the battery behavior on an application-based and vehicle-related level. For this purpose, real driving operation and motion data are collected and evaluated, system and cell type effects are identified and a comparison between real multi-stress scenarios and an accelerated aging characterization procedure on laboratory level is performed.

The project “BetterBat” aims to assess the technical and systemic compatibility between battery technologies and untapped use cases. The FTM focuses on use cases in the mobility sector, particularly for commercial vehicles and leads the work package that identifies the cost-effectiveness of status quo battery cells.
