We congratulate the Institute for Power Electronics and Electrical Drives on moving into the new research building CARL – Center for Ageing, Reliability and Lifetime Prediction of Electrochemical and Power Electronic Systems – on the Melaten campus.
Three large laboratory halls as the heart of CARL and an interdisciplinary research network of ten core professorships, about 20 other chairs and institutes of RWTH Aachen and Forschungszentrum Jülich will now make it possible to push groundbreaking research work on battery aging and lifetime prediction of power electronics from a holistic perspective. “We want to understand down to the atomic and crystal level how energy storage devices function and respond to different requirements,” says Professor Dirk Uwe Sauer of ISEA, explaining the fundamental idea behind CARL.

Test benches for load and environmental simulations are set up in the first laboratory area. For example, this involves electrical, mechanical, chemical or climatic influences on the materials and systems of batteries and power electronics. Here, aging processes are run and analyzed in fast motion, as it were, in order to be able to investigate their causes in detail.

The second laboratory area deals with the construction of prototypes. The performance of entire systems or even individual components is to be examined here in order, for example, to be able to rule out material or design faults at an early stage.

Finally, the third laboratory area is dedicated to physical-electrochemical analysis. With the aid of an analysis chain for structural and material investigations, which will include a state-of-the-art computer tomograph with unprecedented resolution, the structures of the material can be examined and analyzed down to atomic resolution.

Consideration will be given to both the end user and the developer of machines and materials for the production of batteries and power electronics. “With our research results, we can help accelerate development cycles and ultimately save money by optimally configuring systems,” says Professor Sauer. This is because the question of service life is essential for economic considerations. For example, it is important for car manufacturers to be able to estimate depreciation periods, warranty services and reliability as part of functional safety.

Honoring outstanding achievements by RWTH Aachen graduates

The Friedrich Wilhelm Prize is awarded annually by the foundation of the same name in the form of prize money to students and researchers at RWTH Aachen University who have been selected for their outstanding achiements in their theses. Among this years recipients are Maxim Christian Maria Müllender, Master of Science, from the Institute of High Voltage Equipment and Grids, Digitalization and Energy Economics and Laurids Schmitz, Master of Science, from the Institute for Power Electronics and Electrical Drives. Both winners were recognized due to their excellent masters theses.

Funding for research and teaching

The name of the foundation goes back to the Prussian crown prince and later Emperor Friedrich Wilhelm III., who founded a polytechnic institute in the Rhine province in 1858 using a donation from the Aachen and Munich fire insurance companies. In doing so, he laid the foundation for both the Rheinisch-Westfälische Technische Hochschule and the Friedrich Wilhelm Foundation, which is founded 1865 by the legal predecessor of todays Aachener und Münchener Beteiligungsgesellschaft. Since then, the promotion of research and teaching and the support of students and researchers at the RWTH Aachen have been the central concerns of the foundation.

One of the challenges encountered by research on novel electronic devices is to compare devices based on different materials in a consistent way. RWTH Professor Max Lemme and colleagues from USA, China, and Belgium have now proposed a set of clear guidelines for benchmarking key parameters and performance metrics of emergent field-effect transistors. The guidelines have been published as a Perspective Article in Nature Electronics.

Research on field-effect transistors (FET) has long explored the possibility of replacing silicon as channel material with emerging nanomaterials, such as carbon nanotubes, graphene, transition metal dichalcogenides, organic semiconductors, or ultrathin oxides. The field is thriving and keeps uncovering fundamental aspects of these materials. But when it comes to comparing the performance of different devices, there is often a lack of consistent reporting and benchmarking

“Assessing consistently the potential of new materials for novel transistors is difficult, because the performance depends on many aspects and details of the device structure, and many parameters are interdependent.” explains Prof. Lemme. Further complexity is added to the field by the interdisciplinarity of the research community, which includes electrical engineers, chemists, materials scientist and physicists. The multitude of approaches increases the challenge of reporting and benchmarking results consistently.

To address this situation, Lemme and colleagues have prepared a checklist of device parameters to be reported, as well as a list of recommended benchmarking plots to compare device parameters and performance metrics. In addition, they present an explicit example of how to use the proposed procedure by applying it to the case of FETs based on monolayer molybdenum disulfide (MoS2), which is one of the emerging materials most studied in recent years for transistor application.

“To identify the real advantages and opportunities offered by novel materials in the search for improved transistors, we need to be able to benchmark and report different devices in a consistent way. We also need to make sure that all relevant data are reported every time.” adds Lemme. “We hope that our work will contribute to bring clarity in the community and guide the search for even better devices.”

“ELMAR” project: The ISEA is part of it!

September 30th, 2022 | by

The objective of the ELMAR project is to integrate the use of electric heavy mining machinery in the domestic extractive industry and demonstrate its utility.

A secure supply of mineral raw materials is essential for the competitiveness and prosperity of Germany and Europe. At the same time, raw material extraction results in substantial carbon dioxide emissions and therefore needs to become more sustainable in order to help achieve climate targets and to remain competitive. This includes, in particular, the decarbonization of operations that extract raw material. In Germany, this affects around 1,600 companies with around 2,700 plants and 23,500 employees in gravel, sand, and natural stone production alone.

Up to now, a significant proportion of the energy used in the extraction of raw materials at these plants has been used for internal transport. And most of this energy is being consumed by mobile diesel-powered (heavy-duty) vehicles. Conversion to (battery) electric operation is therefore a key lever for reducing emissions in this sector. This applies to the retrofitting of existing companies as well as to future projects.

 

Decarbonization of Domestic Raw Material Extraction – A Holistic Approach

In the newly launched ELMAR project, a consortium of research and industry partners is investigating how the decarbonization of the raw materials sector can be achieved and implemented in a holistic approach. The project involves the deployment of autonomous electric heavy-duty electric mine transport systems, the adaptation of the infrastructure this requires, and the redesign of operational processes. In addition, the project seeks to optimize the matching of energy demand and energy supply with the help of a connected, model-based and intelligent operational management.

ELMAR lays an important foundation for the integration of electric automated mobile heavy-duty transport machines in raw material extraction,” says Dr. Tobias Hartmann of the Institute for Advanced Mining Technologies at RWTH Aachen University. “Maintaining process reliability in extraction while ensuring security of electrical supply, as well as coupling it to renewable energy sources, we want to demonstrate in representative application scenarios that electrical transport is possible in domestic resource extraction. The holistic approach taking production, energy demand and energy supply aspects int account makes it possible to optimize existing and upcoming operating concepts.”

The consortium consists of two RWTH institutes, the Institute for Advanced Mining Technologies (AMT) and the Institute for Power Electronics and Electrical Drives (ISEA), and industry partners. Volvo Group Trucks Central Europe GmbH, Volvo Construction Equipment Germany GmbH, and Volvo Autonomous Solutions AB (commissioned by VCE Germany GmbH), are participating as construction equipment and transport vehicle manufacturers and automation providers. Other partners include mine operators Mineral Baustoffe GmbH (part of the STRABAG Group), Knauf Gips KG, and Nivelsteiner Sandwerke & Sandsteinbrüche GmbH; AI and cloud-based software providers PSI Fuzzy Logik & Neuro Systeme GmbH and PSI Software AG; and TITUS Research GmbH as a developer of autonomous monitoring systems.

The ELMAR project is scheduled to run until the end of July 2025 and receives around 6 million euros from the German Federal Ministry of Economics and Climate Protection (BMKW) as part of the “Research and Development in the Field of Electromobility” funding initiative.The total project volume is around 11 million euros.
