Abstract:

The container energy storage system is an effective means of solving the energy waste problem caused by the mismatch between the generation and consumption peaks. The development of the container energy storage system is limited by the reason that the life of the lithium battery (hereinafter referred to as the battery) is affected by the batch battery consistency and the heating characteristics. The thermal performance of the battery module of a container energy storage system is analyzed based on the computational fluid dynamics simulation technology. The air distribution characteristics and the temperature distribution of the battery surface are then obtained. Moreover, the influence of the size and the arrangement angle of the guide plate on the gas flow and heat transfer characteristics is studied. The results show that the maximum and average temperatures of the cooling surface of the battery have a downward trend with the increases of the guide plate width and layout angle of the guide plate. The reasonable arrangement of the guide plate can reduce the temperature of the cooling surface of the battery to below 60 ℃, which is in line with the reasonable working environment of the general battery. The research results provide a technical reference for the wide application of the container energy storage system.
