Multizone Modelling of Heat Transfer Characteristics of an Electrochemical Cell Pack

In recent years, significant efforts have been made for reduction in emissions and import of crude. Several government schemes (FAME II) have been initiated to accelerate faster adaption to e-mobility in India. The battery is at the heart of any electric vehicle (EV) and its performance capabilities determine the faster adaption to e-mobility. In the present work, the thermal behavior of the electrochemical cells is analyzed by employing analytical solutions and numerical technique. One-dimensional prismatic geometry of a cell in a battery pack is considered for the analysis. Spatial and temporal variation of the temperature inside the cell and coolant fluid, with heat generation as input profile and Indian driving cycle is obtained by solving governing differential equation using MATLAB. The model was validated with published result. The present result can be helpful for designing full electric vehicle battery pack by optimizing critical design parameters such as size, weight and cooling power requirements.
