Development of a Thermal Model for Lithium-Ion Batteries for Plug-In Hybrid Electric Vehicles

Year: 2012

Type: article

Abstract: This paper describes a novel thermal model for lithium-ion battery technology. The model has been developed in Matlab/Simulink, which is based mainly on the electrical parameters such as thermal resistance, thermal capacitance, and thermal convection. In this study, a new methodology is presented for extraction of the model parameters based on the Matlab/Simulink parameter optimization tool. The results exhibit that the error percentage between the simulated and experimental results is less than 5%. According to this model, the battery cell temperature can be kept in a safe operating region by coupling the surface temperature of the battery with the heating and cooling systems. This will allows to enhance the battery performances on one hand and to avoid thermal runway effect on the other hand. The proposed battery model is not only useful for pouch battery cells but can be employed for any battery design concept.
