What Should We Do If The Lithium Ion Battery Catches Fire?

Analyzing the causes of battery fires, we take a look at Tesla's recommendations when lithium batteries are needed to put out fires

1. If you encounter a small fire and the flame does not spread to the high-voltage battery part, you can use a carbon dioxide extinguisher or ABC dry powder extinguisher to extinguish the fire.

2, in the thorough inspection of the fire source, do not contact any high voltage components, often use insulation tools to check.

3, if the high voltage battery in the fire bent, twisted, damaged, in short, become unlike, or suspect that there is a problem with the battery. Then the water consumption should not be too little when extinguishing the fire, and the fire water should be sufficient.

4. Battery fires can take up to 24 hours to extinguish completely. The use of a thermal imager ensures that the HV battery is completely cooled before the accident is fully completed. If you do not have a thermal imager, you must monitor the battery for reignition. Smoke indicates that the battery is still hot, and the monitor will remain in control until at least one hour after the battery is no longer smoking.

Electric vehicles can catch fire at temperatures "in excess of 2,760 degrees Celsius," according to the U.S. Fire Department, and "using water or foam can cause violent flames as the water molecules break down into explosive hydrogen and oxygen." So it is not safe to put in a small amount of water, electric cars alone need tens of tons of water.

Simply put, lithium battery fire suppression uses a lot of water to cool the battery, takes a long time and patience, and cooling is key.
