1. How to prevent the battery from catching fire
(1) Use the original charger as much as possible. It is forbidden to use high voltage charger and different types of battery charger.
(2) Charging should be carried out outdoors (or garage, balcony, toilet) as far as possible, and ensure that there are no flammable and explosive substances around, and avoid charging in the sun where is very hot;
(3) Try to charge it in the daytime with someone there. The charging time is generally less than 10 hours. Once the charging indicator turns green, unplug the charger as soon as possible.
(4) Do not modify the electric vehicle privately, and do not pull wires and sockets to charge the electric vehicle in violation of the safety requirements of electricity use.
(5) Electric vehicles should be parked in the shed or covered with plastic cloth to avoid rainwater leakage and potential short circuit.
(6) In case of aging and exposed wires, timely repair shall be carried out. If the battery is hot, smelly, the indicator light does not turn green for a long time, or the battery is bulging during charging, stop charging immediately.

2. How to put out a battery fire
When a lithium battery is on fire, because oxygen is not needed during the discharge process, the general fire extinguishing method is difficult to be effective. Water molecules will decompose into explosive hydrogen and oxygen, so it is not safe to put out a fire with a small amount of water; The carbon dioxide contained in the fire extinguisher will be reduced to carbon by lithium, which is exothermic and the particulate carbon will be burned again.
(1) When the fire is under control, if the battery is in charge, cut off the power in time. It is better to move the burning battery to the outside, use a large amount of water to cool the battery, or use sand to bury the battery. If the battery continues emitting smoke after the flame is extinguished, this indicates that it is still hot and there is the possibility of re-burning. The monitoring shall be maintained until at least one hour after the battery no longer emits smoke.
(2) Once the fire is found to be out of control, make sure to escape from the fire site immediately and call the fire alarm immediately.
