Does a liquid cooling system work for a battery pack?
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.
How does a liquid cooling system affect the temperature of a battery?
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.
What is the maximum temperature of the battery pack?
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.
What is the temperature distribution of power battery pack based on reference design?
The temperature distributions of the power battery pack based on the reference design are shown in Figure 10. At the end of the discharge, the temperature of the upper battery module was higher, the heat distribution of the battery module 7 was more concentrated, and the maximum temperature approximately reached 43.4 °C.
Why is indirect liquid cooling used in power battery pack?
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.
How many cells are in a power battery pack?
It is mainly composed of a pack lower case, battery modules, and liquid-cooled plates. Specifically, the pack is composed of 84 cells. Figure 3 shows the schematics of the structure of the coolant circulation system in the power battery pack.
