Computational fluid dynamic analyses were carried out to investigate the performance of a liquid cooling system for a battery pack. The numerical simulations showed promising results and the design of the battery pack thermal management system was sufficient to ensure that the cells operated within their temperature limits.
Considering that the indirect liquid cooling method is adopted in this power battery pack, the natural convection heat transfer between the battery and the external environment and the radiation heat transfer (which contributes to a small proportion) can be neglected.
For three types of liquid cooling systems with different structures, the battery’s heat is absorbed by the coolant, leading to a continuous increase in the coolant temperature. Consequently, it is observed that the overall temperature of the battery pack increases in the direction of the coolant flow.
Experimental setup The experimental apparatus of the liquid immersion cooling battery pack was shown in Fig. 14, which primarily consisted of three parts: the circulation system, heating system, and measurement system. The coolant was YL-10 and it exhibited excellent compatibility with all the materials and devices used in this experiment.
The maximum measured temperature of the power battery pack was 46 °C, located at the No. 1 measuring point of the battery module 7, and the minimum temperature was 38 °C, located at the No. 2 measuring point of the battery module 3, and the temperature difference reached 8 °C after the discharge.
When the battery module is discharged at a rate of 2C, the flow rate is no less than 12 L/h. In addition, when the range of flow rate is 12 ∼ 20 L/h, Z-LCS, F1-LCS or F2-LCS should be adopted. When the range of flow rate is higher than 20 L/h, four kinds of liquid cooling systems can be used.
