AI Technical Summary

Technical Problem

When a battery pack in an existing liquid-cooled lithium battery energy storage container experiences a temperature anomaly, the liquid cooling medium sprayed by the nozzles is difficult to reach the abnormal battery pack at the bottom, and may affect or damage nearby normal battery packs.

Method used

Two water inlet pipes were designed and connected to three-way solenoid valves respectively. The flow of the water inlet pipes was regulated by the solenoid valves to directly deliver cooling medium to the abnormal battery pack and discharge it through the fire drainage pipe to avoid the cooling medium affecting the normal battery pack.

Benefits of technology

It enables accurate forced cooling and fire suppression of abnormal battery packs, avoids damage to normal battery packs by the cooling medium, and improves the stability and reliability of the system.
