The Beijing Fire Department interviewed 11 express delivery companies. What suggestions were made for the fire safety of electric vehicles?

my country has a large number of electric vehicles and a high social ownership. Taking Quzhou, Zhejiang as an example, the per capita electric vehicle ownership is close to 2:1. Electric vehicle fires often occur during the charging process. The main reasons are short circuits in their own electrical circuits, excessive load on the charging circuits, electric vehicle battery failures, etc. Although the new electric vehicle safety technical standards have been officially implemented in our country, it will take some time to promote product upgrading. Currently, electric vehicles produced using flammable and combustible materials such as plastics and polyurethane still exist in large numbers in society. In addition, in order to maximize profits, some production and sales companies cut corners in the production and sales process, and even replace unqualified parts or manufacture inferior OEM electric vehicles, which seriously affects the safety of electric vehicles.

Through daily fire supervision and inspections and fire case analysis, it is very common for many car owners to park their electric vehicles in stairwells, foyers, aisles or near safety exits for temporary convenience. Some even park their electric vehicles from home? Flying cable? Go to the parking lot to charge your electric car. Once an electric vehicle catches fire, the resulting toxic gas will fill the entire evacuation channel and nearby residents' homes in a very short period of time. If the electric vehicle is illegally parked in public gathering places or group rentals, it can easily cause serious consequences. Casualties. In recent years, many major fire accidents have occurred in a rental house in Sancun, South Street, Daxing District, Beijing, resulting in 18 deaths and 24 injuries. The cause of the fire was a short circuit in the power cord of an electric vehicle parked in the foyer on the first floor. , the power cord of the electric vehicle was short-circuited and the surrounding combustible materials caught fire.

An analysis of electric vehicle fire accidents in recent years shows that most of their owners are residents of urban-rural fringes, urban villages or migrant workers, and some are even school students. This group of people has a strong demand for daily use of electric vehicles, but at the same time they have insufficient understanding of their fire hazards, do not have a solid grasp of relevant laws and regulations, and lack the knowledge and skills for electric vehicle fire prevention, fire fighting, and fire escape and self-rescue. study. For example, on May 5, 2019, an electric bicycle malfunction caused a fire in a self-built private house in Xilong Village, Yanshan District, Guilin City, Guangxi Zhuang Autonomous Region, resulting in 5 deaths and 38 injuries, including 5 students from Lijiang College of Guangxi Normal University and 24 injuries.

Electric vehicle fire safety supervision is a full-chain work involving production, sales, and use. Although the fire safety problems of electric vehicles are directly reflected in the form of fires, it is difficult to achieve a "radical cure" by relying only on one or two departments such as fire rescue agencies. It requires industry and information technology, public security, housing construction, market supervision, and fire protection. The rescue, emergency management, planning, comprehensive law enforcement and other departments carry out comprehensive management throughout the entire chain. Judging from the current situation, many departments still only focus on daily supervision of electric vehicles within the scope of their respective responsibilities. There is no exchange of information, and no normal linkage mechanism has been established. As a result, the comprehensive supervision of electric vehicle fire prevention is not efficient, and often The problem of "doing twice the result with half the effort" arises.
