The Fire and Rescue Bureau of the Ministry of Emergency Management reported that from the perspective of vehicle fires, the growth rate of new energy vehicles is relatively large. A total of 19,000 fires of various types of transportation were reported, an increase of 8.8% year-on-year; among them, new energy vehicle ,640, an increase of 32% year-on-year; 3,777 electric bicycle fires, an increase of 35.9% year-on-year, both higher than the average increase of transportation fires.
According to statistics from the Ministry of Public Security, as of the end of June 2022, the national motor vehicle ownership reached 406 million, including 310 million cars and 10.01 million new energy vehicles. The national new energy vehicle ownership accounts for 3.23% of the total number of cars. Among them, the number of pure electric vehicles is 8.104 million, accounting for 80.93% of the total number of new energy vehicles.
With the continuous increase in the penetration rate of new energy vehicles , car spontaneous fires have also occurred frequently. So what is the reason for frequent fires of new energy vehicles?
The cause of fire in new energy vehicles is related to batteries, but it is not only related to batteries. There are many factors that cause fire in new energy vehicles. At present, there are fires caused by fire and electricity use factors, and fires caused by external collisions.
is mainly: external collision. Currently, new energy vehicles mainly use ternary lithium batteries, and some models use lithium iron phosphate batteries. Both are liquid lithium-ion batteries and will burn violently after being damaged by external forces.
Vehicles exposed to high temperatures, whether they are fuel vehicles or electric vehicles, may spontaneous combustion.
For a long time driving, the battery load will increase, which will increase safety hazards. At the same time, improper charging will also cause fires. For car companies, they should pay attention to and pay attention to the safety performance of new energy vehicles, improve the stability and protection capabilities of power battery , and at the same time improve customers' awareness of product maintenance and troubleshooting.
For car owners, when using cars in daily life, they should pay attention to using the car according to the specifications, driving smoothly, reducing chassis scratches, charging the vehicle strictly in accordance with the specifications, and paying attention to regular maintenance; avoid long-term use of the car in the scorching sun in summer, try to park in a cool place when parking to avoid direct sunlight, and can be pasted on invisible car jackets as an auxiliary. For the increasingly serious outdoor climate environment, Baoye has exclusively developed a high-weather-resistant TPU invisible car jacket, so that the car is not afraid of extreme weather in the scorching sun and severe cold weather, easily resisting natural corrosion such as acid rain and bird droppings, and effectively preventing the aging of the original paint of the car.
In fact, judging from the number of new energy vehicles in my country and the fire data on new energy vehicles, there are not many new energy vehicle combustion accidents. Because new energy vehicles are now vigorously developing, people pay more attention and discussion about them. However, if new energy vehicles want to develop for a long time and replace fuel vehicles one day, then their safety performance needs to be continuously improved and improved to bring users a safer and more environmentally friendly travel experience.
