Battery cycler to generate open li-ion cell aging data and models

Battery degradation is relevant for the lifetime, cost, and life cycle analysis of electric vehicles and stationary storage. Publicly available, reusable battery aging data is scarce and aging experiments are time-consuming and expensive. This poster gives a brief overview of existing battery aging data and models. We then present our battery cycler hardware, which we intend to use to generate open battery degradation data and models. After analyzing the switching behavior, efficiency, and control behavior of the hardware, we give an insight into the generated data and the user interface of the battery cycler. Finally, we provide an outlook on the further development of the project.
