Development of 2D Thermal Battery Model for Lithium-ion Pouch Cells

This paper represents a simulation model for a 2D-thermal model applied on a Lithium-ion pouch battery. This model is able to describe the transient response of the thermal distribution accurately. The heat generation parameters used in this model have been obtained experimentally from dedicated estimation technique. The experimental and simulation are performed at different charge and discharge current rates. The experimental results are in good agreement with the developed model. The battery thermal distributions using natural and forced convection cooling are studied.

Lithium-Ion Capacitor - Optimization of Thermal Management from Cell to Module Level

This paper represents the thermal behavior of a lithium-ion capacitor. In this study, an extended parameter analysis has been realized for observing the thermal behavior when applying dedicated load profiles. Based on the performed analysis, an electro-thermal model and a 3D thermal model have been developed for future optimization of a thermal strategy. The model has been implemented using COMSOL Multiphysics and parameters were obtained from experiments on a 2300-F lithium-ion capacitor cell from JM energy. The accuracy of this model is tested under different operating conditions and simulations are in agreement with experimental results. The developed models are in good agreement with the experimental results, which indicates that the models can be used for the design and optimization of the thermal management.
