Most electric power batteries are made of ternary cells, and some are composed of lithium-iron phosphate cells. Regular battery pack systems are equipped with battery BMS to prevent overcharge, over-discharge, high temperatures, and short circuits. Protection, but as the battery ages or is used improperly, it is easy to cause the battery to catch fire and cause a fire. Moreover, battery fires are generally relatively large and difficult to extinguish for a while. It is impossible for ordinary users to carry a fire extinguisher with them, so electric vehicle batteries Once a fire breaks out, how can we quickly put it out?
Below we provide several methods, and here we provide several methods that are widely used in practice:
1. The battery fire is not big
If the battery is not very hot and there is no risk of explosion, you can use water to directly extinguish the fire, or use dry powder, carbon dioxide, and sand to directly extinguish the fire;
2. The fire is relatively large and there is a risk of explosion.
If there is a risk of explosion, you must first ensure your own safety, cover it with SARS, and use a large amount of water to extinguish the fire. Since the combustion of the battery does not depend on external oxygen, the energy inside it is sufficient to continue burning, so using dry powder will have little effect. It may even cause deflagration, so water-based sand and soil should be used to extinguish fires.
Many people mentioned that both dry powder and carbon dioxide can be used to extinguish battery fires, but we recommend using sand and water first. Although both can be used to extinguish battery fires, the efficiency is different. Of course, it depends on the environment and fire extinguishing conditions of the country at that time. A better way is to immerse the burning battery in water.
3. When the fire cannot be effectively controlled
You must call 119 for firefighting assistance in time and pay attention to your own safety. Although carbon dioxide can play a role in oxygenating and cooling, improper use can cause frostbite on the hands or suffocation when used in a small space.
