The results of the effort show that poor airflow organization of the cooling air is a significant influencing factor leading to uneven internal cell temperatures.
Are lithium battery energy storage systems safe?
Therefore, lithium battery energy storage systems have become the preferred system for the construction of energy storage systems , , . However, with the rapid development of energy storage systems, the volumetric heat flow density of energy storage batteries is increasing, and their safety has caused great concern.
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.
How many lithium phosphate batteries are in an energy storage system?
Energy storage system layout. There are 24 batteries in two rows fixed inside the battery pack，as shown in Fig. 2. Thus, the energy storage system consists of 336 LIB cells. The LIBs are square lithium iron phosphate batteries, each with a rated voltage of 3.2 V and a rated capacity of 150 Ah.
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 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.
