Dimensional and Parametric Study on Thermal Behaviour of Li-ion Batteries

Abstract

Safety is the primary concern in developing Electric Vehicles (EVs). Recent accidents on electric vehicles involving thermal runaway event have set drawbacks in EVs deployment around the world. Battery thermal management needs to be considered carefully during the design process. This work uses an integrated model of Li-ion batteries starting from the electrochemical process in the electrodes. The model is used to analyze the effect of both dimensions and materials on thermal behavior of Li-ion batteries. The results demonstrate that different designs are prone to suffer from the distinct risk of thermal runaway event. The results are expected to be a guideline to design batteries for EVs.
