Abstract
The current paper simulates the thermal management of Li- ion battery modules of 6x5, 3x10 and hexagonal array arrangements. High-fidelity 3-D CFD simulation is carried out using commercial CFD software ANSYS ICEPAK®. An experimental study of battery array arrangement of Li-ion was carried out for validating the simulation results. Forced air convection mode was used for transporting energy from the battery module to the environment. Post-validation, the thermal analysis of the various array arrangement of battery system was investigated at various environmental conditions. It was realized that the hexagonal array arrangement was more effective than the 6×5 and 3x10 cell arrangements for controlling the temperature within the cells and battery module. The convective heat transfer coefficient is optimized to maintain the optimal temperature ranges of Li-ion cells for different inlet velocities and ambient temperatures. Finally, Inlet velocities and duct sizes for different ambient temperatures were suggested for the effective and efficient functioning of Li-ion battery array arrangement for electric vehicles.
