Degradation Study of a Swappable Li-ion Battery Module For Frugal L6e BEV

Popis výsledku v původním jazyce

This paper presents a simulation platform developed within the EU-funded GIANTS project, aimed at development of frugal L-category battery electric vehicles (BEVs). The platform integrates a modular 1D longitudinal vehicle dynamics model—based on key vehicle resistances and map-based powertrain efficiencies—with an electrochemical “Pseudo-2D” (P2D) battery model that enables detailed simulation of Li-ion cell degradation and aging. As a demonstration of its capabilities, the platform was used to perform a part of a life cycle assessment (LCA), a degradation study of a single battery module intended for a passenger L6e-class vehicle. The assessment covered 160 charge-discharge cycles, simulating two years of typical vehicle use in European ambient conditions, during which the battery cells exhibited a capacity loss of less than 3 %. Additionally, the impact of cell aging on vehicle energy consumption and electrical range was evaluated, revealing an increase in energy consumption and a corresponding electric range reduction of up to 5.2 % using the aged battery cells.
