Abstract
Due to growing climate change concerns driven by automobile emissions, the depletion of fossil fuels, and the rising cost of crude oil, electric vehicle (EVs) has become more popular as form of transportation. Energy storage systems are one of the key areas receiving intense attention in ongoing development of electric vehicle. While the energy storage systems for EVs are primarily lithium-ion batteries (LIB). Unfavorable operating temperatures can affect the safety, performance, and degradation of batteries. Therefore, it has become crucial to look further into the thermal behavior of li-ion battery. Using simulation (COMSOL) and experimental technique, thermal analysis of cylindrical li-ion batteries with nickel manganese cobalt oxides (NMC) chemistry is carried for 1C charge and discharge rate at atmospheric conditions (27°C). The simulation technique covers the measurement of surface temperature of battery cells with the help of heat generation rate as input and monitoring output temperature at multiple sensor locations. Utilizing experimental technique, simulation technique accuracy is validated. For 1C charge and discharge rates at atmospheric temperature, the simulation investigation technique suggested in this work forecasts the battery cell surface temperature with a minimum 92.3 percent accuracy during the whole load cycle. The research's thermal investigation can assist for designing suitable thermal management system as well as battery management system operating strategies.
