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 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.

What is the temperature unevenness in a battery pack?

The results show that the optimized solutions 1 and 2 are both top-suction and bottom-blowing airflow organization types. 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.
