“…Behi et al 9 established a mature heat pipe air cooling system to control the temperature of Li ion battery/module under high current (184 A) discharge rate. Their results showed that the maximum temperatures of battery and module are reduced by 35.8% and 23.8%, respectively.…”
When a lithium-ion battery works under high current, its working temperature is easy to exceed the allowable working temperature, resulting in the decrease of battery life. This may cause the non-uniformity of the internal working temperature of the battery and affect the working parameters of the battery. Therefore, an effective thermal management system is needed to enhance the thermal performance of the battery, improve the work efficiency, and extend the service life of the battery. In this study, we propose a new type of fork type mini-channel cooling plate based on genetic optimization algorithm to reduce the working temperature of battery and obtain better thermal uniformity.First, the thermal performance of co-current type cooling plates is experimentally and numerically studied. The heat transfer ability of cross flow cooling plates used to cool the Li-ion Battery is evaluated by parametric method. Second, a multi-objective genetic algorithm optimization is finally performed, considering the balance of the maximum value for temperature and pressure drop.Compared with the previous study, the reduction of temperature difference of this cooling plate can be up to 2 C. In contrast, the pressure drop penalty and thermal resistance of the optimized cooling plates can be reduced by 20% and 40%, respectively. Thirdly the thermal performance of a battery module with eight battery cells is also examined numerically. The maximum ΔT of the battery pack among cells is 4.83 C for V = 48 mL/s, which implies that the battery pack can work normally. This study indicates that batteries with the proposed new cooling plates have much better temperature uniformity.

“…Some researchers have added fins to straight‐channel LCP to improve the performance of LCP.

Due to its high thermal sensitivity, a power lithium‐ion battery for vehicles requires an efficient cooling system to ensure safety and good performance. Excellent heat dissipation capacity enables the liquid cold plate cooling system to have better application prospects. However, all existing cold plates improve their cooling capacity by increasing the complexity of their structure. Therefore, directly opposite inlet and outlet cavity cold plate cooling systems with simple structures are established. Two kinds of cavity cold plates (Model I and Model L) with different inlet and outlet positions are analyzed using the numerical simulation method. The effects of inlet and outlet sizes, coolant mass flow rate (qm), and inlet and outlet positions on the temperature field as well as the cold plate pressure drop are studied. According to the results, maximum temperatures of batteries appear at four corners of cavity cold plates, which are lower than 35 °C. The cooling capacity and temperature uniformity of Model I cooling systems are better than those of Model L. However, the heat dissipation capacity of Model L is more sensitive to qm than that of Model I. Pressure drop of Model L is smaller. This method meets the heat dissipation of vehicle pouch lithium‐ion batteries.
