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.
To verify the effectiveness of the cooling function of the liquid cooled heat dissipation structure designed for vehicle energy storage batteries, it was applied to battery modules to analyze their heat dissipation efficiency.
It can be seen that the new liquid-cooled shell structure has good heat dissipation and temperature equalization performance in the battery charging and discharging process. The variation of cell module temperature, temperature difference, and inlet/outlet pressure drop with coolant flow rate is shown in Fig. 18.4.
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.
In summary, the optimization of the battery liquid cooling system based on NSGA-Ⅱ algorithm solves the heat dissipation inside the battery pack and improves the performance and life of the battery.
Thus, a liquid cooling system for the battery pack is generally integrated with the AC system of the vehicle through a refrigerant cooled chiller to deal with the cases when the coolant radiator is not capable of bring the coolant temperature down to the required pack inlet temperature . Figure 3.
