Abstract
In this study a 1D electrochemical-thermal model is coupled with a 3D thermal model in order to predict the heat generation and corresponding temperature distribution in a battery cell. The developed model is verified
against experimental data for a 20 Ah lithium iron phosphate (LFP) which is operating at 20 °C ambient
temperature. The model is then adjusted to accommodate for 10Ah and 40 Ah cells by decreasing and
increasing the surface area of each cell as well as the tab dimensions. The temperature distribution of the
different cells are studied employing fin cooling as well as indirect liquid cooling system. Simulation results
highlight that the temperature gradient within the surface of the 40 Ah cell is almost 1.9 and 1.3 times that
of the 10 Ah and 20 Ah cells, respectively. Moreover, it is found that the fin cooling method by employing
aluminium plates between the cells is not a good choice when applied to large format batteries. Whereas, by
employing the indirect liquid cooling, a very uniform temperature along with low temperature gradient is
achieved even under high discharge rate. When the two cooling units have the same volume, the obtained
volumetric temperature gradient with fin cooling is equal to 20.5, 27.5 and 34.7 °C for the 10 Ah, 20 Ah and
40Ah respectively, whereas the corresponding value in case of the indirect cooling is 4.7, 5.2 and 6.2 °C
respectively
