No.
When the lithium battery fuse is blown or the circuit is overloaded or shorted. The fuse is blown to protect the battery and other circuits from damage. Once the fuse blows, an internal circuit break often occurs and current cannot flow normally.
How long does it take for a lithium battery in an electric vehicle to cool down if it catches fire?
The most correct way to To extinguish a lithium battery fire is to unplug the power source and use a dry powder fire extinguisher or carbon dioxide fire extinguisher.
Since lithium batteries are electrical components, using these two fire extinguishers can minimize the damage to lithium batteries. At the same time, it is not recommended to use water to extinguish lithium battery fires, because itit exists. There may be charged equipment nearby. There are some safety risks when using water to extinguish fires. If there is no fire extinguisher, sand and earth can also be used to put out the fire.
Since lithium batteries will reignite if not cooled, it is very important to cool the battery with plenty of water. (Note) Continue watering.
The following measures are taken to prevent lithium battery fires:
1. If all batteries are charged on a dedicated charging stand, riding electric bikes will be safer.
2. The cargo rack should have large wheels that are easy to move and be made from non-flammable materials. And kick him out. Nothing stands in the way of the charging station passing in front of the door.
3. In the event of a fire, the first reaction is to pushremove the charging stand outside.
4. Place batteries, chargers and smoke detectors on the charging stand. There is only one extension cord attached to the charging rack, so there will be no other interference when you push the charging rack out of the door. When you push the charging stand out of the door, the power plug should be easily unplugged.
5. Use a timer on the charging stand's power supply to avoid charging while you sleep at night.
It takes 24 hours to put out the lithium battery fire and cool it down. When there is no external condition for ignition, the lithium will turn off and shut down.
Lithium-ion batteries are made up of three basic parts: 1. The positive terminal, usually lithium manganese oxide, lithium cobalt oxide, lithium nickel oxide, etc. 2. The negative terminal,usually she; is a material of graphite, lithium titanate, lithium silicon or lithium germanium, etc. 3. The electrolyte, usually an organic solvent obtained from nonaqueous salts, serves as a medium for the movement of lithium ions in the positive and negative electrodes, and as a battery insulator.
When a lithium-ion battery is hit by a weight of 5 kg and falls freely from a height of 0.6 m, 25 J of energy instantly appears inside the battery, causing the battery temperature to increase by 120°C. Lithium ions have high activity, so this type of battery is very sensitive to external forces. When struck or dropped from a height, the battery heats up internally, causing it to spontaneously ignite.
In the event of a fire, first turn off the power supply. If the battery has high heat, bulging surface, smoke, etc. during the tankge, this indicates that the battery will malfunction soon. Spontaneous combustion or even explosion may occur, so the power supply should be turned off as soon as possible.
When the battery ignites spontaneously, the battery should be cooled immediately and continuously. Using water to turn off the battery is the most ideal solution. If the fire is large, you can use an ABC dry powder fire extinguisher or carbon dioxide fire extinguisher to put out the open fire, then use water to continue to cool the damaged battery. Keep an eye on the auto-ignition battery. is still hot, continue to use water to cool the battery until it is completely cooled.
