Abstract:

The numerical simulation of a container type energy storage system velocity field and temperature field were carried out, according to standard k- model, D-O radiation model and lithium battery thermal characteristic. The simulating results of the basic case show that, compared with the stay away from the air conditioning area and adjacent air conditioning area, there are a big difference about the wind uniformity and the temperature difference between the battery modules. The basic case was optimized by adding the wind guide plate in the air channel and the structural adjustment. The simulating results of the optimized operating case show that, the improved flow field and temperature field distribution are more well-distributed, the temperature difference between the battery module is effectively reduced.
