The battery powering an EV contains highly energetic active materials and flammable organic electrolytes. Usually, an EV battery catches fire due to its thermal runaway, either immediately at the time of the accident or can take a while to gain enough heat to ignite the battery chemicals. There are numerous battery abuse testing standards and regulations available globally. Therefore, battery manufacturers are always in dilemma to choose the safest one. Henceforth, to find the optimal outcome of these two major issues, six standards (SAE J2464:2009, GB/T 31485-2015:2015, FreedomCAR:2006, ISO 12405-3:2014, IEC 62660-2:2010, and SAND2017-6295:2017) and two regulations (UN/ECE-R100.02:2013 and GTR 20:2018), that are followed by more than fifty countries in the world, are investigated in terms of their abuse battery testing conditions (crush test). This research proves that there is a need for (a) augmenting these standards and regulations as they do not consider real-life vehicle crash scenarios, and (b) one harmonised framework should be developed, which can be adopted worldwide. These outcomes will solve the battery manufacturers dilemma and will also increase the safety of EV consumers.}, language = {en} } @article{StegerNitscheArbesmeieretal.2020, author = {Steger, Fabian and Nitsche, Alexander and Arbesmeier, Alexander and Brade, Katja and Schweiger, Hans-Georg and Belski, Iouri}, title = {Teaching Battery Basics in Laboratories: Hands-On Versus Simulated Experiments}, volume = {63}, journal = {IEEE Transactions on Education}, number = {3}, publisher = {IEEE}, address = {Piscataway}, issn = {1557-9638}, doi = {https://doi.org/10.1109/TE.2020.2970554}, pages = {198 -- 208}, year = {2020}, abstract = {Contribution: Prior studies comparing the effectiveness of different laboratory learning modes do not allow one to draw a universally valid conclusion, as other influences are mixed with the learning modes. In order to contribute to the existing body of work and to add another piece to the puzzle, this article demonstrates an improved methodology to evaluate the effectiveness of computer-simulated laboratories in comparison to hands-on exercises using a battery basics practical course as a case study. Background: Computer-simulated experiments are becoming increasingly popular for conducting laboratory exercises in higher education and vocational training institutions. To ensure the consistent quality of laboratory learning, an accurate comparison between the results of simulated experiments and practical hands-on experiments is required. Intended Outcomes: In this article, the achievement of the following learning objectives were compared between the two laboratory modes: 1) comprehension of the most important parameters of battery cells and 2) knowledge on how these parameters can be determined using adequate experimental procedures. Application Design: To avoid interference of factors other than laboratory mode on the learning, laboratory instructions and experimental interfaces ensured identical execution of the experiments in the compared modes. Using a counterbalanced methodology, the two laboratory modes alternated by the session, while the experimental procedures remained constant regardless of the respective modes. Findings: Tests taken by the participants after conducting the laboratory experiments revealed that hands-on laboratories resulted in statistically significantly better student performance than simulated laboratories. This difference was even more pronounced for the participants that finished a vocational education and training program before the university studies.}, language = {en} } @inproceedings{StegerArbesmeierNitscheetal.2019, author = {Steger, Fabian and Arbesmeier, Alexander and Nitsche, Alexander and Brade, Katja and Schweiger, Hans-Georg and Belski, Iouri}, title = {Laboratory learning}, booktitle = {Varietas delectat… Complexity is the new normality: SEFI 47th Annual Conference Proceedings}, subtitle = {influence of the perceived laboratory mode on learning outcomes}, editor = {Nagy, Bal{\´a}zs Vince and Murphy, Mike and J{\"a}rvinen, Hannu-Matti and K{\´a}lm{\´a}n, Anik{\´o}}, publisher = {SEFI}, address = {Br{\"u}ssel}, isbn = {978-2-87352-018-2}, doi = {https://www.sefi.be/proceedings/?conference=2019-budapest-isbn-978-2-87352-018-2}, pages = {1897 -- 1907}, year = {2019}, language = {en} } @inproceedings{StegerNitscheBradeetal.2018, author = {Steger, Fabian and Nitsche, Alexander and Brade, Katja and Belski, Iouri and Schweiger, Hans-Georg}, title = {Energiespeicher-Praktikum an der TH Ingolstadt}, booktitle = {Tagungsband zum Forum der Lehre an der TH Ingolstadt}, subtitle = {reale versus simulierte Experimente}, editor = {Waldherr, Franz and Walter, Claudia}, publisher = {THI / DiZ}, address = {Ingolstadt}, issn = {1612-4537}, url = {https://didaktikzentrum.de/publikationen/dina-und-tagungsbaende}, pages = {90 -- 97}, year = {2018}, language = {de} } @inproceedings{StegerNitscheBradeetal.2017, author = {Steger, Fabian and Nitsche, Alexander and Brade, Katja and Belski, Iouri and Schweiger, Hans-Georg}, title = {Teaching Energy Storages by means of a Student Battery Cell Test System}, booktitle = {Proceedings of the 45th SEFI Annual Conference 2017: Education Excellence for Sustainability}, editor = {Quadrado, Jos{\´e} Carlos and Bernardino, Jorge and Rocha, Jo{\~a}o}, publisher = {SEFI (Soci{\´e}t{\´e} Europ{\´e}enne pour la Formation des Ing{\´e}nieurs)}, address = {Br{\"u}ssel}, isbn = {978-989-98875-7-2}, url = {https://www.sefi.be/conference/2017-azores/}, pages = {169 -- 176}, year = {2017}, language = {en} }
