Estimation of the state of charge and the state of health is therefore essential. The traditional way uses the voltage level of a battery to determine those values. Modern metal air batteries provide a flat voltage characteristic which necessitates new approaches. One promising technique is the electrochemical impedance spectroscopy, which measures the AC resistance for a set of different frequencies. Previous approaches match the measured impedances with a nonlinear equivalent circuit, which needs a lot of time to solve a nonlinear least-squares problem. This paper combines the electrochemical impedance spectroscopy with neural networks to speed up the state estimation using the example of zinc air batteries. Moreover, these networks are trained with different subsets of the spectra as input data in order to determine the required number of frequencies.}, language = {de} } @inproceedings{LoechteGebertHorsthemkeetal.2018, author = {L{\"o}chte, Andre and Gebert, Ole and Horsthemke, Ludwig and Heming, Daniel and Gl{\"o}sek{\"o}tter, Peter}, title = {State of Charge Depended Modeling of an Equivalent Circuit of Zinc Air Batteries Using Electrochemical Impedance Spectroscopy}, series = {International Conference on Time Series and Forecasting: Proceedings of Papers, 19-21 September 2018, Granada (Spain)}, booktitle = {International Conference on Time Series and Forecasting: Proceedings of Papers, 19-21 September 2018, Granada (Spain)}, isbn = {978-84-17293-57-4}, pages = {625 -- 636}, year = {2018}, abstract = {Metal air batteries provide a high energy density as the ca-thodic reaction uses the surrounding air.

State estimation is quite complicated as the voltage characteristicof the battery is rather flat. Especially estimating the state of chargeis important as a secondary electrolysis process during overcharging canlead to an unsafe state. Another technique for state estimation is theelectrochemical impedance spectroscopy. Therefore, this paper describesthe process of setup and measuring a time series of impedance spectraat known states of charge. Then these spectra are used to derive anequivalent circuit.

In many teaching systems, the student is required to use a particular programming language or development environment. This paper presents an intelligent tutoring system to support blended learning scenarios, where the students can choose their programming language and development environment. For that, the system provides an interface where the students request test data and submit results to unit test their algorithms. The submitted results are analyzed by a machine learning system that detects common errors and provides adaptive feedback to the student. With this system, we are focusing on teaching algorithms rather than specific programming language semantics. The technical evaluation tested with the implementation of Mean and Median algorithm shows that the system can distinguish between error cases with an error rate under 20\%. A first survey, with a small group of students, shows that the system helps them detect common errors and arrive at a correct/valid solution. We are in the process of testing the system with a larger group of students for gathering statistically reliable data.}, language = {en} } @article{LoechteGebertHemingetal.2018, author = {L{\"o}chte, Andre and Gebert, Ole and Heming, Daniel and Sanders, Tilmann and Gl{\"o}sek{\"o}tter, Peter}, title = {State of Charge estimation of zinc air batteries using electrochemical impedance spectroscopy}, series = {Neural Computing and Applications}, volume = {2018}, journal = {Neural Computing and Applications}, publisher = {Springer}, pages = {1 -- 9}, year = {2018}, language = {de} } @inproceedings{Mertens2018, author = {Mertens, K.}, title = {„String-Dunkelkennlinien-Technik zur Diagnose von PV-Anlagen", Solarkampagne des Kreises Steinfurt, Betriebs- und Sicherheitstagung der DGS, Berlin, 17.10.2018}, year = {2018}, language = {de} } @misc{Mertens2018, author = {Mertens, Konrad}, title = {"Solarstrom auf meinem Dach: Wie geht das?
