As the vehicle industry grows increasingly devoted to sustainable mobility, hybrid-electric propulsion systems with batteries with enhanced gravimetric energy density and cyclability qualities have drawn a lot of attention. In this setting, the widely established lithium-ion battery technology, despite providing decent performance, has partially attained a certain limit. The battery market is thus exploring new technologies capable of strengthening battery electric vehicle safety and overall life cycle assessment. Under such circumstances, the all-solid-state battery (ASSB) appears to be a valid answer. The current research, with the purpose of establishing the cycle capabilities of ASSB in practical applications, places emphasis on the development of a numerical ageing model based on the open-source coding language, Python.
