1. Micro-short circuit inside the battery. This short circuit phenomenon may be caused by external impact or lithium dendrite growth in lithium batteries.
2. The battery is out of control. The chemical reaction inside the battery may generate a lot of heat. If the heat dissipation is not good or the battery temperature is too high, thermal runaway may occur, which may cause the battery to catch fire.
3. The battery is impacted by external force. If the electric scooter is hit by severe external force, it may damage the structure of the battery, resulting in short circuit or thermal runaway of the battery.
In order to prevent the electric scooter from catching fire, it is suggested to pay attention to the following points during use:
1. Avoid overcharging the battery. Overcharging may lead to battery damage or even danger.
2. Avoid using electric scooters in high temperature environment. The high temperature environment may cause the battery temperature to be too high, thus causing danger.
3. Avoid external force hitting the battery. If the battery is hit by external force, it should be stopped immediately and inspected and maintained.
4. Check and maintain the electric scooter regularly. Regular inspection and maintenance of electric scooters can ensure the normal operation and safety of batteries.
When the electric scooter catches fire, the following measures should be taken as soon as possible:
1. Cut off the power immediately. Never put out the battery fire with water, as this may lead to electric shock and explosion.
2. If there are flammable materials around, they should be removed immediately to prevent the fire from expanding.
3. If the fire is large, call 1 19 as soon as possible and evacuate to a safe place as soon as possible.
In short, in order to ensure the safety of yourself and others, please strictly abide by the relevant regulations and instructions when using electric scooters.
