Abstract

This paper deals with the thermal modeling and experimental validation of a large prismatic Li-ion battery. A lumped model representing the main thermal phenomena in the cell, in and outside the casing is proposed. Most of the parameters are determined analytically, using physical and geometrical properties. The heat capacity, the internal thermal resistance and interfacial thermal resistance between the cell and its cooling system are experimentally identified. The proposed model is validated with a precision of 1°C.
