Research on battery liquid-cooled system based on the parallel connection of cold plates

The performance of a power battery is greatly affected by temperature. This paper optimized the power battery liquid-cooled system and put forward the way of adding fins to the liquid-cooled plate to improve the cooling efficiency of the thermal management system. In this paper, a liquid-cooled battery system model was established, and the thermal balance performance of the parallel liquid-cooled system was studied through numerical analysis. The results show that the parallel liquid-cooled system with an optimized shunt could maintain the maximum temperature of the battery system below 44.31 °C, and the temperature difference of the battery system could maintain at 3 °C, which could meet the temperature requirements of the power battery system.
