How do I ensure a suitable operating environment for energy storage systems?

To ensure a suitable operating environment for energy storage systems, a suitable thermal management system is particularly important.

What is energy storage system (ESS)?

The energy storage system (ESS) studied in this paper is a 1200 mm × 1780 mm × 950 mm container, which consists of 14 battery packs connected in series and arranged in two columns in the inner part of the battery container, as shown in Fig. 1. Fig. 1. Energy storage system layout.

What is the maximum temperature of a battery pack?

However, due to the poor airflow circulation at the top of the container, temperature unevenness still exists inside the battery pack, with the maximum temperatures of 315 K and 314 K for the two solutions. Both optimized solutions 3 and 4 belong to the type of airflow organization with central suction and air blowing at both ends.

How to reduce the temperature of a battery pack?

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.

What is the temperature uniformity of a battery pack?

As can be seen from Fig. 11, Fig. 12, the battery pack under the initial scheme shows a poor temperature uniformity in general. And the maximum temperature of the single battery reaches 325 K, which exceeds the permissible range. Battery packs 3 and 10 near the inlet are more effectively cooled, with a lower temperature of 308 K.

What is the corresponding heat generation power of a battery?

The inlet boundary is a velocity inlet of 2.6 m/s and the outlet boundary is a pressure outlet of 0 Pa. In addition, the temperature of the supply airflow is 293.15 K. The battery has a discharge rate of 0.5C and an internal resistance of 0.3mΩ. Using Bernardi's theory, the corresponding heat generation power of the battery is 1132.91 W/m 3.
