The results show a great difference in temperature at various heights of the battery cabinet. The batteries of the lower height level have a temperature about 25°C; the batteries of the higher height level have a temperature near 55°C. There are also differences in the temperature distribution for various battery cabinets.
The results reveal that the average temperature of each cabinet is about 39°C; the standard deviation of the battery temperatures is about 15°C, and the maximum difference in battery temperature is about 40°C.
The single battery temperature is defined by the area-weighted averaged surface temperature of the battery. To analyze the temperature uniformity, we applied the standard deviation (STDEV) and the maximum difference (dTmax) to measure the variance.
A battery-storage system has a maximum heat generation about one tenth that of a fully loaded data center. Also, a BESS is on its maximum power for a brief interval to satisfy the demand of a rapid fluctuation of the grid; the data center must sustain a high load under an extended period , , .
After modification, the maximum temperature difference of the battery cells drops from 31.2°C to 3.5°C, the average temperature decreases from 30.5°C to 24.7°C, and the coefficient of performance (COP) increases four-fold. The modification shows an improvement in temperature uniformity, overall temperature and COP.
Xu et al. investigated the flow pattern and temperature distribution of the container-type BESS via CFD; they proposed a solution to improve the cooling performance by installing a guide plate at the flow path. The average battery temperature of that new design was decreased by 4.57°C; the maximum temperature difference was decreased by 3.65°C.
