Estimating Surface Temperature Profile Of Li-Ion Battery Under Several Conditions

Abstract

In recent years, electric vehicles have become increasingly popular as a highly efficient and environmentally friendly transportation option worldwide. This trend is primarily due to the growing global awareness of the importance of pollution and carbon emissions from road transportation. According to the International Energy Agency (IEA) latest report, the sales of electric vehicles have exceeded 10 million in 2022. Electric vehicles consist of various components that are used for propulsion. One of the crucial components that stores energy for propulsion is the battery. The efficiency and lifetime of batteries depend on the temperature during usage. To ensure long lifetime and efficiency of batteries, temperature management is crucial. Batteries perform best when the temperature is neither too low or high. Therefore, the thermal issue of battery in electric vehicles is essential and has been continuously researched and developed. Heat in batteries and thermal modeling of batteries are important for estimating battery temperature profiles.
