Abstract
A liquid cooling plate structure with a parallel non-equal-length channel was proposed to improve the heat dissipation ability of the power battery pack of a commercial vehicle and to reduce the energy consumption of the cooling system of the battery pack. A simulation model of a liquid cooling prismatic lithium-ion battery pack was established to optimize the structure of liquid cooling plate. The results show that the cooling plate not only meets the cooling capacity of the battery pack, but also can effectively control the pressure drop. The pressure drop of the liquid cooling plate decreases by 12.5 kPa, and the maximum temperature and maximum temperature difference in the battery pack decrease by 0.26 ℃ and 0.27 ℃, respectively. Adjustments on the flow rate and temperature of coolants could enhance the heat dissipation capacity of the battery pack to keep the battery pack working within a reasonable temperature range.
