The lithium ion battery, thanks to their high density and high power, became promotes element for hybrid and EV vehicles. After several recent researches, it has been proved that lithium ion batteries are currently confronts a problem of temperature rise during their operation discharge, which affects the batteries performance, efficiency and reduces the life of lithium ion battery. However, this work is set to access the three dimensional analytical modeling based on Greens Function technique to study the thermal behavior of lithium-ion battery during discharge with different discharge rates (0.3C, C/2,1C, 2C,) and strategies natural convection cooling on the surface of the battery is performed.

Abstract. The paper has built 3D-FEA models to simulate the electro-thermal behavior of Li-ion battery cells with Pouch Cell and Prismatic Cell by ANSYS. As for two models, the Li-ion battery system is simplified as a single equivalent battery layer (Pouch Cell) or multiple equivalent battery layers (Prismatic Cell) with the equivalent electrodes and separator. They were simulated under air cooling conditions. Simulations were compared with available battery temperature measurements. This shows that the 3D electro-thermal model applied in this study characterizes the electro-thermal behavior of the Li-ion battery cells reasonably well.
