The Chair of Electrochemical Energy Conversion and Storage Systems at ISEA of RWTH Aachen University conducts research at the interface between material and cell development on the one hand and mobile and stationary battery applications on the other. The focus is on the investigation and quantitative modelling of ageing processes and battery life time prediction, battery diagnostics in hardware and software, battery pack design, integration of battery systems in vehicles of all kinds and in power grids for UPS functions, grid stabilisation and integration of renewable energies. The research groups operate their own demonstration facilities and vehicles for testing batteries, as well as a fully equipped laboratory for conducting post-mortem investigations.  ISEA is a partner in the Helmholtz Institute Münster (HI MS) of the Forschungszentrum Jülich and is the scientific and organisational head of the “Center for Ageing, Reliability and Lifetime Prediction for Electrochemical and Power Electronic Systems (CARL)”, for which the research building financed by the state and federal governments is currently under construction. It offers unique interdisciplinary research opportunities for the investigation of ageing processes, service life and reliability together with institutes of electrical engineering, mechanical engineering, materials science, chemistry, physics, informatics and mathematics.

In the BattNutzung cluster, ISEA is involved in the cluster-accompanying project greenBattNutzung and in the projects NUBase, OSLiB, BALd, MADAM4Life, BetterBat, SimBAS and Model2Life. The aim of ISEA’s work in these projects is to investigate fundamental factors influencing battery ageing and safety, to create models to describe and diagnostics to monitor these processes, and to specifically match cell design and planned battery application. Whilst investigating these questions, ISEA can make use of extensive preliminary work in the area of investigating battery ageing mechanisms from projects such as eperformance, MEET-HiEnD I – III, openBat and Raffzyklen. In addition, there is in-depth experience in the field of battery system modelling from projects such as Everlasting, DUETT and HV Modal. In addition, ISEA conducts intensive research on topics related to the overall system evaluation of battery systems in projects such as BOB-LKW, Eliptic, ZeEUS and E2Fuels. Through the position of Prof. Dr. rer. nat. Dirk Uwe Sauer as cluster coordinator for the Batterienutzungskonzepte cluster, ISEA is also committed to cross-cluster networking.

The activities of the “Chair of Production Engineering of E-Mobility Components” (PEM) at RWTH Aachen University address all issues related to the topic of electrified mobility, especially with regard to the components of electromobility. In addition to looking at the production, development and recycling of (traction) batteries, the chair also researches the production of electric motors and fuel cells. Important here is the integration of research into possible practical applications. Key elements for this are practical research and its implementation in industry. Expertise in these areas has been built up through numerous research projects.

The eLAB is also affiliated with the PEM. In the eLAB, together with other research institutions, both components and vehicles can be built and the latest technologies researched and tested.

technologies can be researched and tested.

The “Chair of Production Engineering of E-Mobility Components” (PEM) at RWTH Aachen is involved in the projects “Model2Life” and “SimBAS” in the BattNutzung cluster. In both projects, simulation models for battery cells and systems are being built. The aim of the models is to improve the reusability of batteries in a 2nd life usage and to optimize them in terms of cost and performance.

The related competences in the areas of simulation of battery systems and remanufacturing could be built up by the chair in research projects like “HitCell”, “POLICE” or “BatteReMan”. In the context of the projects in BattNutzung, the simulation models already built up can be used and further developed. This previous knowledge is to be made available and further developed in joint exchange with project and cluster partners.

The Institute of Statistics (ISW) sees its essential tasks in the communication, development, and implementation of statistical ideas, models, methods, and procedures. In research, the main focus of Maria Kateri is on areas of applied and mathematical statistics, stochastic modeling, and reliability theory, with a long and broad experience in model building, statistical methods development (frequentist and Bayesian approaches), data analysis, and simulations. She is internationally established in active research fields in categorical and ordinal data analysis, multivariate statistics, statistical decision theory, lifetime data analysis and accelerated life testing (ALT). Furthermore, she is active in application-oriented research, consulting and projects with partners from industry and business.

The team of Maria Kateri is internationally established in actual ALT-research (optimal experimental design and statistical inference under censoring). Model building, development of statistical methods, model validation, prediction, and uncertainty quantification are of great importance for the investigation of reliability and aging processes of batteries under various application conditions, and thus will be core working areas of BattNutzung (BALd project).

BALd

The Institute for Machine Elements and Systems Engineering investigates the fundamental structural and tribological behavior of machine elements and incorporates it in experimentally validated model descriptions. These model descriptions are used to analyse and design the functional, loss and NVH behavior of complex technical systems with focus on the drivetrain of wind turbines and mobile machines as well as electric vehicles. The results are numerical and constructive designs of specific technical solutions including proof of the required system properties on large test stands. Numerous experiences with such model-based solutions up to the conception of configurable products enable the MSE to research and develop methods of Model-Based Systems Engineering as a central element of future industrial product development processes.

As co-founder of the Center for Systems Engineering, the Institute for Machine Elements and Systems Engineering shapes the change from document-based and geometry-oriented product development towards digital, physical model-based processes. In doing so, the MSE develops methods that enable highly iterative, agile and in part automated product development by interlinking the individual development steps and tools, in order to meet the challenges of increasing interdisciplinarity in the development of cyber-physical products. Thus, the methods enable the holistic optimization of product systems. As a partner in the competence cluster, the MSE enables the systematic, integrated development and early virtual validation of concepts for traction battery systems that address the requirements of the 2nd life concepts of repurposing and remanufacturing.
