Description

Technical Field

[0002] Under the vision of carbon peak and carbon neutrality, the energy storage market has entered the fast lane of development, but the risk of safety accidents has also increased, especially the problem of battery thermal runaway has caused people's concerns. Batteries, like people, need to work in a comfortable temperature environment. Batteries that are in a high temperature environment for a long time will significantly shorten their life, degrade their performance, and even cause safety accidents. Therefore, accurately controlling the temperature of the energy storage system is an important part of ensuring the stable operation of the power station.

[0003] The number of battery modules in the existing energy storage system is usually large. The existing air duct structure is used to achieve ventilation and heat dissipation. There is a problem that the air volume of each air outlet is uneven, which makes the air volume entering the battery modules at different positions inconsistent, resulting in uneven heat exchange of the battery modules. After the heat is accumulated, the temperature of the local battery module is high, and the temperature difference between the battery modules is large, resulting in rapid attenuation of the battery module capacity and life, poor consistency of the energy storage system, and even thermal runaway and other safety problems in severe cases; at the same time, the heat dissipation of the PCS in the existing energy storage system is only dissipated through the louver channel, which has the problem of poor heat dissipation effect. Therefore, the utility model proposes an air-cooled industrial and commercial cabinet energy storage system. Utility Model Content
