Simulating Electric-Vehicle Battery Degradation with Physics Based Battery Model

Abstract

Physics-based mathematical representations of batteries are the most complete and complex battery models in the literature. These models are exemplified by PyBaMM; a well documented, easy to use, open-source python library which can be used to simulate physics-based battery models of various levels of complexity and detail. This work describes the process, the workflow and the viability of combining an Electric Vehicle powertrain model, constructed in Simulink, with a PyBaMM model in order to observe an accelerated battery degradation cycle using a physics-based model.
