Sometimes even extremely brief project descriptions reveal huge potential. Even if it says little more than "Investigate thermal replacement models for batteries". When Marcel Nöller read the call for proposals from the Karlsruhe Mobility Systems profile region in 2019, he immediately thought of the countless possible technical uses of the application. The topic piqued his interest, which is why he took on the project as a research assistant at the IPEK - Institute for Product Development at the Karlsruhe Institute of Technology. He only discovered the commercial potential when he realized that hardly anyone in industry was openly addressing the topic. He and his research partner Yunying Zeng are now on the verge of founding a spin-off company. With a test procedure based on battery cell replacement models (BEM) in hand, which not only forms the business basis of their start-up ZeNo, but also profoundly changes the development and construction processes surrounding batteries. The two have researched the technology as part of the ICM project INDU7 - SenseBEM, among others.
