Energy storage container air duct design

What is a containerized energy storage battery system?

The containerized energy storage battery system comprises a container and air conditioning units. Within the container, there are two battery compartments and one control cabinet. Each battery compartment contains 2 clusters of battery racks, with each cluster consisting of 3 rows of battery racks.

Where is the air supply duct located?

The air supply ducts are positioned directly above the battery racks, with six identically sized air conditioning vents along the duct sidewalls, opposite the partition. The control cabinet is situated on the left side of the battery compartments, while the air conditioning units are installed on the right side of the container. Fig. 1.

Can CFD simulation be used in containerized energy storage battery system?

Therefore, we analyzed the airflow organization and battery surface temperature distribution of a 1540 kWh containerized energy storage battery system using CFD simulation technology. Initially, we validated the feasibility of the simulation method by comparing experimental results with numerical ones.

Are air cooling systems good for energy storage?

Air cooling systems, favoured for their low cost, simplicity, and space efficiency, are widely utilized in practical energy storage applications . However, they exhibit lower efficiency at high discharge rates and temperatures, resulting in uneven battery temperatures [16, 17].

What is a containerized storage battery compartment?

The containerized storage battery compartment is separated by a bulkhead to form two small battery compartments with a completely symmetrical arrangement. The air-cooling principle inside the two battery compartments is exactly the same.

What is the best airflow distribution in a battery compartment?

Combined with the temperature distribution on the surface of the battery table and the final ranking results of each evaluation index, the airflow distribution in the battery compartment is most ideal when the air supply angle is 90° and the return air vent is at Z = 0.85 m on the side of the fire door.
