How can an electric car charging will be fired? What is the cause of fire?

Electric bicycle, electric motorcycle, electric tricycle as an important composition of electric vehicles, as well as fires and battery fires caused by their supply power, often cause a large amount of black smoke and toxic and harmful gases during combustion. In order to ensure the safety of people's lives and property, create a good social security environment, reduce and prevent the occurrence of electric vehicles and battery fires, is suggesting that the warning is as follows: electric car fires occur in night, especially at night concentration charging time, not easy to find, After discovering, it is difficult to save and can cause casualties; electric bicycle fires can occur in the community carport, the first floor of the building, the walkway, and the residents, there is a large number of toxic and harmful flue gas, causing casualties; electric vehicles and battery in violation Easy to cause electrical accidents during charging. The reason for such fires has the following: 1, the quality of the electrical components is not.

Some manufacturers use core components such as inferior controllers, chargers, batteries, and motors to maximize economic interests, leading to problems such as the technical indicators of different specifications models, without charging overcurrent protection functions, people are buried Under unsafe hidden danger. A part of the electric bicycle undervoltage overcurrent protection technical indicators are unqualified, and some do not even install short-circuit protection devices, even if short-circuit protection devices are installed, they are not connected to the line or repair, and the modification process is unauthorized, resulting in short circuits. Loss of protection.

2, line arrangement irregular. Some companies have not selected suitable linear lines as required, and the line connectors do not have waterproof, moisture-proof function. At the time of modifying the electric bicycle, the line is arbitrarily selected, and the protection device is not set, and the assembly process is unreasonable.

Once there is a high voltage or large current pass, it is easy to fire, fever, fever, heat generation,. 3, charging behavior is not safe. First, the battery overtime is overcharged, charger, battery continuous heat, thus causing fire; second, privately lit up the temporary wire, from the indoor pull line to the outdoor electric bicycle charging, power cord is easy to cause fire; The charger and battery model do not match, consumers replace the electric bicycle battery or purchase similar models during use, the mismatch of the parameter model is too high, the battery is abundant, and the heat is too high.

Explosion 4 is that the battery charging position is not safe. In the public stair, the corridors, the safe exports, etc., the area is charged, and the safety passage is blocked after the fire, which is easy to cause casualties.

4, use maintenance and maintenance is not in place. First, use an over-stage service battery, some owners do not replace the battery in order to save money, it is easy to use, it is easy to cause a fire; the second is private anti-theft, new electricity load, self-installed anti-theft power cord The power bus is connected, and it is not connected to the electrical protection device. It is easy to cause a fault to fail to cause a fire.

The three is to pay attention to maintenance and inspection. The internal part is easy to loosen. After the negative pole is short, it is more Under the use of large currents, fire caused fire; fourth, after the electric bicycle has failed, self-improvement or delivery to non-professional repairs, freely change the internal line, may cause the internal line of electric bicycles to mess, and then trigger a fire; five is overload riding pair Motors and batteries are easily caused by damage, buried hidden dangers.
