High-power battery energy storage systems (BESS) are often equipped with liquid-cooling systems to remove the heat generated by the batteries during operation. This tutorial demonstrates how to define and solve a high-fidelity model of a liquid-cooled BESS pack which consists of 8 battery modules, each consisting of 56 cells (14S4p).
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.
A power battery pack is composed of 10 lithium-ion power battery cells, and the arrangement is shown in Fig. 2. The volume of the box is 180 mm × 140 mm × 247 mm, and there is a 5-mm gap between the battery and the battery. The geometric modeling of the whole battery cooling system was established by the SCDM software.
Feng studied the battery module liquid cooling system as a honeycomb structure with inlet and outlet ports in the structure, and the cooling pipe and the battery pack are in indirect contact with the surroundings at 360°, which significantly improves the heat exchange effect.
When the battery module is discharged at a rate of 2C, the flow rate is no less than 12 L/h. In addition, when the range of flow rate is 12 ∼ 20 L/h, Z-LCS, F1-LCS or F2-LCS should be adopted. When the range of flow rate is higher than 20 L/h, four kinds of liquid cooling systems can be used.
The test result verified the accuracy and the rationality of the model, but it also showed that the reference design could not reach the qualified standard of thermal performance of the power battery pack. Based on the heat dissipation strategy of liquid cooling, a novel improved design solution was proposed.
