As one of the most popular means of daily transportation for Chinese people, electric cars have added a lot of convenience to our life, but a few days ago, "Beijing electric car fire killed 5 people" incident has made people temporarily "talk about cars changed color". In fact, the electric vehicle itself is just a kind of transport tool, although there is a fire hazard, but we do not need to regard it as a monster, as long as in accordance with the scientific method to use, natural can effectively prevent the occurrence of electric vehicle fire accidents. After consulting a large number of information, the author sorted out an electric vehicle fire prevention guide for everyone, hoping to help everyone.
Fire characteristics of electric vehicle
To prevent electric vehicle fire, we must first understand its characteristics, electric vehicle fire will cause serious consequences, mainly caused by the following characteristics:
Electric vehicle fire development is rapid: the data obtained after the professional test shows that electric vehicle battery failure within 30 seconds there is a great possibility of open fire, 2 minutes will be able to ignite plastic parts on the car;
Producing large amounts of deadly smoke: Electric fires, its smoke contains carbon monoxide, sulfur oxide, the toxic gas such as hydrogen sulfide, and also has the characteristics such as light, heat, the men once inhaled easily into a coma, severe cases may even suffocation death, is the consequences of this characteristic, once someone trapped in the scene of the fire, to escape the possibility is very small;
Short time high temperature: after electric vehicle fire occurs, the temperature can reach 1000 degrees in a short time, and the flame temperature can reach a very horrible value of 1200 degrees in 3 minutes, which can quickly ignite the combustible material around the fire to spread and expand.
Electric vehicle fire risk
The occurrence of any thing has its reason place, the occurrence of electric vehicle fire also has its inducement certainly, believe everybody wants to know very much. After finishing, the author found that the occurrence of electric vehicle fire usually has the following types of reasons:
Vehicle maintenance is not timely: electric vehicles do not maintain inspection for a long time, it is very easy to appear electrical line insulation wear or aging fracture, will increase the risk of fire caused by electrical line failure. Moreover, due to the short battery life of electric vehicles, failure to replace them within a specified period of time will also cause internal circuit faults and cause fires.
Vehicle modification: Some people in the process of using electric vehicles for the convenience of consideration, will privately modified electric vehicle lines and accessories or increase the capacity of the battery, this kind of operation will lead to electric vehicle line failure, resulting in line overload and heat, resulting in fire.
Non-standard use: charging time is too long, many cars at the same time, private connecting battery, using cheap not compliance charger and battery, such as indoor charging these non-standard electric vehicle charging ways are also triggered one of the important reasons of electric fire, because it is the use of compliance to make electric cars in the phenomenon such as overload, short circuit, causing a fire.
Product defects: There are many types of electric vehicles on the market, some people will buy some "three products" because of cheap, most of these products have not passed the inspection and certification of relevant departments, there are design defects, there are great safety risks, is also one of the important inducements of electric vehicle fire.
Electric vehicle fire prevention knowledge
Understand the electric vehicle fire several major incentives, we can also clearly feel that the occurrence of electric vehicle fire is mostly caused by incorrect use, from the root to prevent the occurrence of electric vehicle fire, the following points must be noted:
Purchase of compliant products: when choosing electric vehicles, we should pay attention to the selection of electric vehicles with complete certificates, high market visibility and good reputation. At the same time, we should also pay attention to check whether electric vehicles have the functions of undervoltage, overcurrent protection and short circuit protection.
Buy qualified accessories: in the process of using electric vehicles, if batteries, chargers and other accessories appear defects, we must go to the original purchase shop or regular parts store to buy, must not covily buy cheap quality unqualified products.
No personal modification: if there is a requirement of high battery life, choose the model with satisfactory battery life when buying the electric car. It is not allowed to expand and modify the small capacity battery or replace the mismatched battery after purchase.
Regular inspection and maintenance: if there are small problems in the car in time to the regular channel repair, even if there is no problem should be checked every six months or a year to professional maintenance organizations, eliminate hidden dangers from the root.
Standard use: choose regular charging place to charge, and control the charging time according to the instructions. When charging the vehicle, it should be carried out outdoors as far as possible, or the battery should be removed and charged separately. The charging line should choose the appropriate wire diameter, and the wire should not be arbitrarily connected.
Install fire warning accessories: accessories with temperature warning function can effectively prevent the occurrence of electric vehicle fire accidents. Such as the multi-functional locator Zhiqibao, in addition to the basic positioning function, but also real-time monitoring of the temperature of the electric vehicle, once the temperature is abnormal, immediately through the mobile phone APP and telephone two ways to alarm the user, to remind the user to deal with in time, to avoid a tragedy.
Finally, I would like to say to you that the electric vehicle fire is terrible, but the electric vehicle itself has brought great convenience to many people's lives, so we must not give up eating for fear of choking, the electric vehicle product itself and the people who ride the electric vehicle add subjective negative impression. We also hope that the users of electric vehicles can keep in mind the lessons and use electric vehicles in a correct and compliant way, so as to eliminate the fire hazards of electric vehicles from the root and ensure the safety of themselves and people around them!
