Abstract:
The paper discusses the problem of computer simulation of the state of charge (SOC) dynamics of lithium-ion batteries. A discrete model which is based on the substitution scheme is used for the problem solution. A computer implementation of the model was performed in Python language, during which graphs of SOC and voltage dependence on time were obtained using constant, pulsating direct discharge current and WLTC (Worldwide Harmonised Light Vehicles Test Procedure) profile current.
Keywords:state of charge, SOC, battery model, equivalent substitution scheme, WLTC.
