How powerful is the explosion of lithium batteries? Co governance takes you to find out

Mondo Science Updated on 2024-02-01

There are nearly 4 million electric bicycles in Jinan, and electric vehicles are deeply loved by the majority of Jinan people because of their small footprint, low cost and high transportation efficiency. However, electric vehicles bring us a lot of convenience at the same time, but also accompanied by some problems, electric vehicles are placed at will, go upstairs at will, charge at will in the corridor and other problems penetrate into our daily life, and these problems will also bring irreparable harm to our daily life.

There are many hidden dangers in charging upstairs, when will the electric car "go upstairs" be closed?

The biggest risk and hazard of electric vehicles upstairs is that electric vehicle charging is very easy to cause fire, and the hazards are mainly manifested in high temperature and toxic smoke in the fire field. Most of the electric vehicles are composed of flammable and explosive materials, and once **, the smoke contains a large amount of highly toxic gases such as carbon monoxide, which is more deadly than high temperatures. According to some data, 80% of electric vehicle fires occur while charging, and 90% of electric vehicle fires cause people** due to placing electric vehicles in the hallway, corridor or aisle. The fifth episode of the "Co-governance" program entered the Yujing Community of Zhongda Huaishu Street, Huaiyin District, Jinan City, and recorded around "how to let electric vehicles go downstairs", aiming to resolve conflicts and build a harmonious home for co-governance.

The battery ** is harmful, experiment to see how fierce it is?

In this episode of the program, the reporter of the "Co-governance" program also conducted an experiment with the fire department, and put the lithium battery removed from the electric vehicle to the designated experimental site, when the battery immediately burned after coming into contact with the fire source, and it was accompanied by thick black smoke floating in the air. If the battery of an electric vehicle is short-circuited, overloaded, impacted, or exposed to high temperatures, the battery will burn**, and as long as one battery of the electric vehicle catches fire, the entire battery will have a chain reaction. From this experiment, we can see that the harm of electric vehicle fire is huge, not only causing property damage, but also endangering personal safety.

Regulating electric vehicle charging depends on the law and self-discipline!

According to the "Fifth Order of the Ministry of Emergency Management of the People's Republic of China" and Article 37 of Chapter 3 of the "Regulations on the Fire Safety Management of High-rise Civil Buildings", it is forbidden to park or charge electric bicycles in the safety exits, evacuation passages, public foyers, and stairwells of high-rise civil buildings. Violation of this provision shall be issued by the fire and rescue agency, and a fine of not less than 500 yuan but not more than 1,000 yuan shall be imposed on non-business units and individuals.

In recent years, high-rise residential fire accidents caused by electric vehicle charging or spontaneous combustion have occurred frequently, the toxic gas produced by the combustion of an electric vehicle can cover the entire room in 30 seconds, and people will suffocate to death within 100 seconds.

How to prevent the safety hazards of electric vehicles upstairs and ensure the personal safety of residents in the community? The fifth issue of "Co-governance" will be broadcast on the Cultural Tourism Sports Channel at 20:30 on September 9, the Urban Channel at 21:00 on September 10, and the Luzhong Channel at 21:00 on September 17.
