Worry! Father and daughter rode and were swallowed by the fire next second! People with electric cars must pay attention to →
On July 18, an electric bicycle suddenly caught fire while driving near Yuhuang villa in Hangzhou.
A pair of father and daughter on the electric bicycle were severely burned and were being treated in the hospital.
At that time, a middle-aged man was riding a bicycle with his daughter sitting in the back seat.
After the fire, the father and daughter were surrounded by a fire.
In the face of this sudden scene, passers-by quickly responded in just 10 seconds The passing drivers came out one after another.
The security guard took the fire extinguisher and rushed over.
Everyone worked together for one minute to quickly put out the fire.
The reporter learned from the witnesses that the cause of the fire may be that the battery of the electric bicycle suddenly exploded, causing the personnel on the vehicle to avoid and get injured.
It is understood that when the fire broke out, a family of three were riding along Yuhuang mountain road.
Two battery cars, father and daughter ride in front, and mother follows behind alone.
Suddenly, the father’s battery car with his daughter made a loud noise and immediately jumped up a fire.
The father and daughter were immediately surrounded by the fire.
“What a pity.
My father and daughter are burned.
The little girl is badly hurt.” Master Zhuang, the security guard at the back door of the sanatorium, sighed facing the wreckage of the battery car, saying that he didn’t want to recall the scene at that time, “I didn’t dare to look carefully.” Here, Master Zhuang used two bottles of fire extinguishers to put out the fire.
Over there, the girl’s father also borrowed a fire extinguisher from nearby, and the staff of Yuhuang villa also carried the fire extinguisher to help.
The fire was almost out before the firemen arrived.
“Three members of the family have different degrees of burns.
The mother is in good condition and the daughter is the most serious.” An investigator at the scene said.
The injured girl Qiqi was born in August 2014.
She should be in the second grade of primary school in September.
At more than 9 p.m.
last night, her mother said: just in the morning, her parents had a rest.
They were going to the bookstore with her child to buy her some extracurricular books.
Originally, the girl took her mother’s electric car, but before leaving, her mother suddenly thought of getting a citizen card and wanted to get a library card for her child, so the girl moved to her father’s car.
“She used to ride in my car.
She said she liked to sit behind her mother.” At 9:30 p.m.
on the 18th, the reporter learned that Qiqi’s operation has been completed, but she can’t come out yet.
She needs to continue to observe in the surgical intensive care unit.
According to the injured girl Qiqi’s uncle told reporters, up to now, the hospital has issued three critical notices, and the family stayed awake all night.
The reporter also learned from the West Lake scenic spot branch of Hangzhou market supervision bureau that next, the relevant staff of the market supervision bureau will learn from their families about the purchase territory of electric vehicles and whether they are 3C certified products.
The reporter will follow up the matter further.
The West Lake scenic spot will also conduct a comprehensive inspection on the electric vehicle sales and maintenance business units within its jurisdiction.
Expert: the maximum probability is the internal explosion of lithium battery! Burn girl’s mother told reporters: the car was bought at a battery car store on Jiangcheng Road, Shangcheng District, two or three years ago.
Last year, my husband also changed a new battery in this car shop, which cost about 500 yuan.
The brand of electric vehicles has not been announced.
The head of the power supply department of a well-known electric bicycle brand R & D center in Zhejiang said after watching the video of electric vehicle spontaneous combustion yesterday that this situation is most likely caused by lithium batteries.
The safety factor of lithium battery is lower than that of lead-acid battery.
He said that at present, electric vehicle batteries in the market are mainly lithium batteries and lead-acid batteries.
Under the same capacity, the mileage of lead-acid battery is much less than that of lithium battery, which is one of the reasons why there are more lithium batteries in the market.
Electrolyte organic matter in lithium battery (lithium hexafluorophosphate) is combustible.
Its positive electrode is lithium ion and its negative electrode is graphite.
Generally, lithium ion is embedded in the positive electrode.
When fully charged, if there is a short circuit, it is easy to cause lithium precipitation.
In addition, its chemical properties are relatively active and can not contact with oxygen in the air.
Once contacted, it is easy to cause heat out of control and violent chemical reaction (such as explosion), electric vehicles are naturally easy to burn.
In addition, when lithium battery electric vehicles are running, under the condition of discharge, the over discharge of a single battery may also cause heating or explosion due to inconsistent battery voltage.
In the past, electric vehicles would emit smoke first.
Why did such a fire suddenly burn this time? The person in charge said that it depends on the specific situation of lithium batteries Which part or specific reason caused the spontaneous combustion? For example, the electric bicycle caught fire.
From the monitoring screen, it is likely that there was an explosion inside the lithium battery at that time.
“The energy of the lithium battery is still very large, and the power of the explosion is no less than that of a small grenade”.
The person in charge reminded that when using an electric bicycle at high temperature, first of all, you can’t charge it for a long time, as long as you ensure 80% power.
Be sure to go to the original store to replace the battery (brand store) for replacement, it is better to replace the charger at the same time, because the voltage and current requirements are different.
It is easy to cause some battery faults when the charger is not matched.
Most importantly, do not take it home for charging.
Once an accident occurs, the consequences at home will be more serious.
When buying an electric vehicle, you should recognize the 3C certification.
Production will be banned by the state from April 15, 2019 Sell electric bicycles and other electric vehicle products that do not meet national standards.
When citizens buy electric bicycles, To recognize 3C certification (CCC certificate, full name: compulsory product certification system).
The standard 3C certification requires that in addition to the whole vehicle, there are nine parts of electric vehicles that need 3C certification, namely: front combination lamp, front steering lamp, brake hose, rear combination lamp, rear license plate lamp, rear-view mirror, reflector, tire and horn.
In addition, electric vehicles can not be approved at will except 3C certified electric vehicles Refit, but not change its engine and battery.
If the purchased electric bicycle does not meet the standard, it has the right to return or replace it, and can report to the market supervision department at the same time.
The electric car has great combustion power.
This accident makes people worried.
How violent is the electric car combustion? Let’s have a look! △ when the electric vehicle is short circuited, it immediately emits thick smoke △ the smoke spreads all over the building in 2 minutes △ the electric vehicle has been burning violently in less than 5 minutes! In addition, don’t be indifferent when you see someone pushing an electric car or carrying a battery to the elevator! Recently, the Ministry of emergency management of the people’s Republic of China announced the regulations on fire safety management of high-rise civil buildings, which added seven fire administrative penalties in the chapter of legal responsibility, which mentioned that if an electric bicycle is parked or charged in the public lobby of high-rise civil buildings, the operating units and individuals who refuse to make corrections can be fined up to 10000 yuan, and non operating units and individuals, The maximum penalty is a fine of 1000 yuan.
The provisions shall come into force as of August 1, 2021.
