However, under the monitoring of big data, it has brought unexpected answers. According to media reports, the global smart Travel Conference opened on September 20. At the meeting, sun Fengchun, academician of the Chinese Academy of engineering and director of the National Engineering Laboratory of electric vehicles, revealed that the fire accident rate of new energy vehicles was lower than that of traditional fuel vehicles, and the combustion accident rate of new energy vehicles in China was significantly lower than that of Tesla. It is understood that at the place where new energy vehicles were first promoted in China, relevant departments have established a national regulatory platform for new energy vehicles. Almost all the new energy vehicles in use in China are connected to the platform. As of September 14, 2020, 3.47 million vehicles have been connected to the national supervision platform, with a total mileage of 162.3 billion km. Through monitoring the operation data of more than 3 million new energy vehicles, academician sun got seven conclusions: < / P > < p > 1. The proportion of fire accidents of new energy vehicles is lower than that of traditional fuel vehicles. The fire accident rate of new energy vehicles in China in 2019 is 0.0049% (187 accidents in 2019 and 3.81 million in 2019). < p > < p > since 2020, the annual fire accident rate of new energy vehicles is 0.0026% (the overall travel mileage has decreased in the first half of the year). According to the data released by the relevant departments of the Ministry of public security, the annual fire accident rate of traditional fuel vehicles is about 0.01% ~ 0.02%. The fire accident rate of new energy vehicles in China is significantly lower than that of foreign countries. According to the 2012-2019 Tesla safety report, a Tesla vehicle burning accident occurs every 280 million km. < / P > < p > China’s new energy vehicles have a combustion accident every 447 million km (2018-2019 national regulatory platform Statistics). Passenger cars account for a large proportion of the vehicles on fire (in 2020, of the 54 vehicles on board, 25 are passenger cars, accounting for 46.3%, special purpose vehicles are 25.9%, passenger cars are 24.1%, and other vehicles are 3.7%). < / P > < p > 6. There are more trains in motion. Among the starting vehicles, 31.4% were in stationary state, 40% in driving state, 17.1% in charging state and 11.4% in unknown state. < / P > < p > at present, fire accidents of various new energy vehicles are often seen on the Internet. In fact, the fire rate of traditional fuel vehicles is higher. Therefore, we should treat the safety of new energy vehicles rationally.
