What should we pay attention to in order to prevent the self ignition of electric vehicles?

because of the characteristics of oil-free, environmental protection and portability, electric vehicles are becoming more and more popular. In the charging process, if the management is not careful, it is also very easy to cause fire. As lead-acid batteries are widely used in electric vehicles, once the charging time is long or the internal circuit of batteries is aging, it will cause fire. Recently, we have received many spontaneous fire incidents of electric vehicles. In order to prevent the occurrence of fire accidents, we remind the owners to pay attention to the following points:

1. The qualified electric vehicles, chargers and batteries produced by manufacturers with production license shall be purchased and used. Do not modify electric vehicles in violation of regulations, and do not use unqualified batteries.

2. It is strictly prohibited to cover the charger with articles during charging, maintain the ventilation and heat dissipation of the charger, and check whether the fan of the charger operates..

3. Please go to the designated place of the underground garage for charging. It is strictly forbidden to connect wires without permission for charging.

4. Strengthen daily self inspection. The electric wires and circuits of electric vehicles need to be checked frequently. Prevent the contact points from sparking and heating due to poor contact, and avoid the occurrence of short circuit and series power accidents due to the aging and wear of lines.

5. The electric vehicles that do not need to be charged shall be parked at the place designated by the 11th floor and the 13th floor. Do not put them together with the charged electric vehicles, so as to cause greater losses in fire accidents.

6. Before charging, the output end of the charger should be inserted into the charging socket of the battery first, and then the input end should be connected to the power supply; the plug of the charging hole and the power plug of the electric vehicle & gt; should be inserted in place, do not plug in half, otherwise it is easy to generate heat and fire.

7. Properly control the charging time. Generally, the average charging time is about 8 hours. If the charging time is long and the heat storage is large, the battery will be heated, which is very easy to cause fire.

8. When charging, keep a certain distance between the car and the car to avoid one car accident affecting more than one car; and try not to have combustibles to prevent rapid spread in case of fire.

9. Chargers with the same configuration shall be used. Chargers with unqualified quality shall not be used randomly. It is strictly forbidden to dismantle the battery box without permission to avoid accidents. Regularly check the safety performance of key components such as batteries and chargers.

After charging, first unplug the 220 V AC plug at the input end of the charger, then unplug the output plug. When plugging in and unplugging the power supply, keep your hands dry; if the battery is not used for a long time, store it after it is fully charged, and make sure to charge it once a month, otherwise it will reduce the service life of the battery.

11. Please do not place combustibles or inflammables in the storage box and rack of electric vehicle to avoid fire after being exposed to high temperature.

12. The electric vehicle shall be regularly repaired and maintained by the personnel of the professional maintenance organization.
