Summary A dynamic coupled electro‐thermal model including the impact of the state of charge (SOC), inner temperature and current flux on resistance and heat generation rate is proposed for prismatic batteries, including the ohmic and polarization resistances and entropy coefficient. This model reflects the interaction between generation rate of heat and temperature distribution and is appropriate to be employed. Subsequently, the dynamic model is implemented to reveal the temperature increase of a Li‐ion prismatic battery with the capacity of 50‐Ah under the conditions of static and dynamic currents. Experiments are performed to demonstrate the model which is given in this article can precisely describe the thermal behavior under the conditions of static and dynamic currents and different ambient temperatures, with an average relative error of 5.87% for the static condition and of 11.81% for the dynamic condition. In addition, comparative studies are utilized to decide the application range of the dynamic model. It shows according to the results that it should be used for the temperature prediction under the condition of dynamic current. As for the static current condition, the static model ignoring the effect of current can replace the dynamic model, although the temperature prediction precision of the dynamic model is slightly higher than that of the static model. Finally, the proposed dynamic model is compared with a resistance‐based thermal model where the heat generation depends only on SOC and is demonstrated to be superior to its counterpart.

“…It is commonly referred to as a liquid cooling plate (LCP). Sheng et al 42 numerically investigated the use of a serpentine channel LCP through examining the thermal effects of channel width, flow direction, flow rate as well as operating current on the temperature distribution. Their results showed that the temperature distribution was substantially affected by the position of inlet and outlet as well as the flow direction, while the maximum temperature rise was predominantly affected by the amount of liquid flow.…”

Thermal management of large-scale Li-ion battery packs is of great significance to their safety and life cycle, which would impact their applicability in electric vehicles. Of the many strategies developed for this purpose, indirect liquid cooling has already demonstrated quite high potentials in thermal regulation of such battery systems. In this study, a compact lightweight serpentine wavy channel configuration was chosen to construct an indirect liquid cooling system for a battery module of cylindrical Li-ion cells. The serpentine channel has a number of six internal minichannels. Experimental test data were used to conduct a comprehensive thermal analysis to examine the highest temperature, the maximum temperature difference, and the heat accumulation percentages, and so forth within the battery pack. Results have revealed the ability of the cooling system to maintain the module temperature within appropriate working conditions for electric vehicle applications for most cycling tests including two driving cycles. Furthermore, the analysis insights raised by this study could be useful in understanding the cooling performance of the liquid-based thermal management systems for electric vehicles.

“…Also, it is important to provide small temperature differences between batteries in a battery pack and the difference between each battery temperature in a battery pack should be under 5°C 4 . In the literature, five different battery cooling methods/strategies which are air cooling, 5‐14 liquid cooling, 15‐24 phase change material cooling/heat pipe cooling 25‐32 and thermoelectric cooling 33,34 are generally presented in order to keep battery temperature in the optimum range 35‐37 .

“…2 In lithiumion batteries, different problems (such as solid electrolyte interphase break down, electrolyte decomposition, oxygen release from cathode material which can lead to fire) can be occurred with the increment of battery temperature. 3 In order to overcome these problems, it is necessary to maintain the batteries in the optimum operation temperature which is in the range of 15 C to 40 C. Also, it is important to provide small temperature differences between batteries in a battery pack and the difference between each battery temperature in a battery pack should be under 5 C. 4 In the literature, five different battery cooling methods/strategies which are air cooling, [5][6][7][8][9][10][11][12][13][14] liquid cooling, [15][16][17][18][19][20][21][22][23][24] phase change material cooling/heat pipe cooling [25][26][27][28][29][30][31][32] and thermoelectric cooling 33,34 are generally presented in order to keep battery temperature in the optimum range.

In this study, a numerical thermal analysis of a lithium nickel manganese cobalt oxide prismatic battery having nominal voltage of 3.7 V and capacity of 26 Ah was performed during air cooling conditions. The effects of discharge rate (in the range of 3C-5C) and air velocity (in the range of 1-3 m s −1) on average battery temperature, maximum battery temperature, and total heat transfer rate are investigated for both flat and finned cooling surfaces. The results showed that air cooling by means of flat cooling surface is only sufficient for low discharge rate and it is necessary to use finned surfaces in order to keep battery temperature in desired operation temperature range for high discharge rate conditions. Analysis results showed that average battery temperature is reduced up to 29%, 32%, and 30% by increasing air velocity for discharge rates of 3C, 4C, and 5C with the usage of flat surface, respectively. In addition, it was seen that the average and maximum battery temperatures are reduced up to 7.9 and 8.6 K with the usage of finned cooling surface instead of flat one. The heat removed from the battery is increased 8.7 W by using finned surface at the maximum air velocity of 3 m s −1 .
