Thermal design and simulation of intelligent energy storage nests for lithium battery

The two cooling schemes of air cooling and liquid cooling for lithium battery energy storage containers are compared in this paper. The results show that liquid cooling has obvious advantages in technical solutions and life cycle cost. Through the thermal simulation of the intelligent energy storage nests and the battery clusters, it is found that the self-contained fan of lithium battery has a better operation effect under the rated air volume, and the space between battery clusters has little influence on the thermal simulation, but it is necessary to retain the safety distance. The temperature consistency between the lithium battery packs in the battery cluster when discharging at full load is poor, which indicates that the lithium battery is not suitable for long-term full load operation. When discharging at partial load, the temperature consistency between the lithium battery packs in the battery cluster is good.
