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.
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.
In this paper, the heat dissipation behavior of the thermal management system of the container energy storage system is investigated based on the fluid dynamics simulation method. 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.
Therefore, adjusting the direction of the fan can improve the flow field inside the container and thus reduce the extreme temperature of the battery. On the other hand, this solution is more effective in improving the temperature uniformity. Fig. 19. Cooling performance of battery packs under different design options.
Due to the thermal characteristics of lithium-ion batteries, safety accidents like fire and explosion will happen under extreme conditions. Effective thermal management can inhibit the accumulation and spread of battery heat. This paper studies the air cooling heat dissipation of the battery cabin and the influence of guide plate on air cooling.
The working condition of module was 1C, and the air speed was set to 4m/s. The results show that the average temperature, maximum temperature and temperature difference in the battery cabin reduced by 4.57°C, 4.3°C and 3.65°C respectively when guide plate added. The air cooling effect of battery cabin was improved by adding guide plate.
