In order to place as many energy storage devices as possible in a limited space, the battery packs of the energy storage power stations are highly concentrated, which may cause problems of insufficient heat dissipation. Under the influence of internal and external factors such as overcharge and overdischarge, overheat, mechanical collision, poor temperature consistency and the like of the battery, the temperature of the battery pack rises sharply, and battery diaphragm collapse and internal short circuit are easily caused, so that thermal runaway is caused. If thermal runaway occurs in the battery module, a fire accident of the system may occur. Therefore, a corresponding heat dissipation device needs to be arranged on the energy storage device to assist in cooling, and meanwhile, the real-time temperature of the energy storage device needs to be monitored.

The working principle of water cooling is as follows: and injecting cooling liquid into the battery box loaded with the battery pack, completing heat exchange work in the process of immersing the battery pack by the cooling liquid, discharging the warmed cooling liquid from an overflow port of the battery box to an external cooling system, and cooling the battery pack again after the cooling liquid is cooled again to realize circulating cooling.
However, in practical application, it is found that the battery pack close to the cooling liquid outlet in the battery box can obtain a better cooling effect, and the battery pack far away from the cooling liquid outlet has a limited cooling effect, so that the heat dissipation conditions of the battery packs in the same battery box are different, and potential safety hazards are generated.
