HEAT DISSIPATION OF LIQUID-COOLED SOLAR
A liquid-cooled BTMS which has a heat transfer coefficient ranging from 300 to 1000 W/ (m2.K), removes heat generated by the batteries via means of a coolant circulation system.
Therefore, lithium battery energy storage systems have become the preferred system for the construction of energy storage systems, , . However, with the rapid development of energy storage systems, the volumetric heat flow density of energy storage batteries is increasing, and their safety has caused great concern.
In this paper, the heat dissipation behavior of the thermal management system of the container energy storage system is investigated based on the fluid dynamics simulation method. The results of the effort show that poor airflow organization of the cooling air is a significant influencing factor leading to uneven internal cell temperatures.
To ensure a suitable operating environment for energy storage systems, a suitable thermal management system is particularly important.
In optimized solution 2, the temperature of the corresponding battery packs is reduced by changing the state of the fan in battery packs 4 and 11. In optimized solution 3, the temperature of the corresponding battery pack has been significantly reduced by further changing the status of the fan in battery packs 1 and 8.
