Discussion: The proposed liquid cooling structure design can effectively manage and disperse the heat generated by the battery. This method provides a new idea for the optimization of the energy efficiency of the hybrid power system. This paper provides a new way for the efficient thermal management of the automotive power battery.
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.
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.
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.
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.
Since the geometric model of the power battery pack is vast and complicated, it is necessary for it to be simplified, considering the heat transfer path. During the high-temperature cooling condition, heat is mainly generated by the battery, transferred to the thermal pad and the cold plate, and finally absorbed by the coolant.
