Abstract

This paper investigates how well the two battery types which are Li-ion and NiMH perform in a sedan electric vehicle (EV) using the simulation program MATLAB Simulink. Three driving cycles categorized as urban, rural, and highway were used in the simulations to analyse battery behavior in various scenarios, with an emphasis on the State of Charge (SoC) as a crucial performance metric. The findings show that over the course of all driving cycles, Li-ion batteries consistently preserve a higher SoC than NiMH batteries. Improved general vehicle efficiency is directly correlated with this superior energy retention. Li-ion batteries offer benefits like a longer lifespan, improved charging efficiency, and lighter weight in addition to encouraging a longer driving range. These results support Li-ion batteries’ suitability to be a EVs preferred energy storage selection, which enhances performance, range, and dependability in practical driving scenarios.
