Energy storage liquid cooling fire extinguishing

What makes a good fire extinguishing system?

An ideal fire extinguishing system should have excellent fire extinguishing and cooling effects, which can quickly extinguish open flames and reduce battery system tem-perature. Specifically, extinguishing systems whose aim it to prevent module-to-module, and beyond, propagation.

Which fire extinguishing agent has the best cooling capacity?

Solid fire-extinguishing agents have the worst fire-extinguishing capacity for LIBs fire. The cooling capacity of the fire-extinguishing agents has a positive effect on the suppression of TR propagation and re-ignition. Clearly, water-based fire-extin-guishing agents exhibit excellent cooling capacity [55, 78].

What is the cooling rate of battery fire extinguishing agent?

When using water mist fire extinguishing agent, the cooling rate of the battery surface temperature is 1.7℃·s −1, and the cooling rate of battery flame is 25.11℃·s −1. When applying ordinary foam extinguishing agent, the cooling rate of the battery surface temperature is 0.96℃·s −1, and the cooling rate of battery flame is 13.1℃·s −1.

Why is lib a good fire extinguishing system?

To satisfy the increasing demand for high capacity, the LIB system becomes pro-gressively larger and contains thousands of batteries. Generally, the fire-extin-guishing effect is better when the extinguishing agent is released to the seat of the fire source.
