Co-simulation approach for analyzing electric-thermal interaction phenomena in lithium-ion battery

Abstract

Battery thermal management for electric or hybrid vehicles is crucial to prevent overheating and uneven heating across a battery pack. Thus, this paper provides a reliable and accurate co-simulation approach that can predict the thermal state inside a battery pack by the electrochemical responses of lithium-ion (Li-ion) battery cells. The approach is based on coupling an electric circuit model and a Computational Fluid Dynamics (CFD) model. The effectiveness and validation of the simulation approach are discussed by comparison with the experimental data.
