Heartache! The electric car burns into a fireball in an instant while riding! The 7-year-old girl was notified of critical illness for the
At about 11 a.m.
on July 18, an electric bicycle in normal operation on yuhuangshan Road, West Lake District, Hangzhou suddenly caught fire.
At that time, a middle-aged man was riding a bicycle with his daughter sitting in the back seat.
After the fire, their father and daughter were surrounded by a fire.
Facing this sudden scene, passers-by quickly responded in just 10 seconds.
Nearby security guards, passers-by The passing drivers came out one after another, and 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 the sudden explosion of the battery of the electric bicycle, which caused the personnel on the car to be unable to avoid and injured.
Video clip: xuanyiyao at 12:30 noon, the reporter rushed to yuhuangshan road.
The cordon was raised at the scene of the accident.
A battery car fell to the ground and burned into a frame.
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 riding in front, mother alone behind.
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 and should be in the second grade of primary school in September.
Zhai Xiaojuan, the girl’s mother, recalled that at noon on the 18th, she and her husband had an electric car.
Her husband rode a bike and sat in the back with her children.
At that time, he was going to Xinhua Bookstore on Jiefang Road to buy extra-curricular reading books for his daughter.
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.
It is understood that the child’s father is the security guard of Yuhuang villa.
After the incident, both father and daughter went to the hospital.
The hospital has issued three critical notices, and the family stayed awake all night.
Both father and daughter’s lives are at stake, and the huge medical expenses are astronomical for the family.
Qiqi’s mother opened the rescue on shuidi.
The original fund-raising of 500000 is far from covering the treatment expenses of her father and daughter.
Therefore, the fundraiser raised the fund-raising target to 2 million twice.
At about 10 a.m.
on the 19th, the relevant personnel of shuidi fund told the extreme news reporter that 2 million donations have been raised in one day.
The reporter also learned from the West Lake Scenic Area Branch of Hangzhou market supervision bureau that next, the relevant staff of the market supervision bureau will ask 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 of the electric vehicle sales and maintenance business units within its jurisdiction.
Experts analyze the spontaneous combustion video of yuhuangshan road electric vehicle: the maximum probability is the internal explosion of lithium battery! Burn girl’s mother told reporters: spontaneous combustion electric vehicle is not a miscellaneous electric vehicle.
It is purchased by a brand electric vehicle store, and the battery is also replaced by the store.
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.
He said that at present, electric vehicle batteries in the market are mainly lithium batteries and lead-acid batteries.
Starting from April 2019, the country has a new national standard, and the weight of electric vehicles shall not be greater than 55kg.
Lead acid batteries are relatively heavy, and the weight of the whole vehicle is difficult to reach within 55 kg.
Therefore, most electric vehicles on the market use lighter lithium batteries.
The 48 volt, 12 ampere hour (capacity) lead-acid battery weighs about 16.4 kg, while the same standard lithium battery weighs only 4 kg.
“Electrolyte organic matter in lithium battery (lithium hexafluorophosphate) , it is combustible.
Its positive electrode is lithium ion and its negative electrode is graphite.
Generally, lithium ion is embedded in the positive electrode.
When it is 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 it is contacted, it is easy to cause heat out of control and violent chemical reaction (such as explosion), Electric cars are naturally easy to burn.
“In addition, when the lithium battery electric vehicle is in the process of driving, under the condition of discharge, the over discharge of a single battery may also cause heating or explosion due to the inconsistent battery voltage.
In the past, the spontaneous combustion of electric vehicles would smoke first.
Why did such a fire suddenly burn this time? The person in charge said that it depends on which part of the lithium battery is spontaneous combustion, or what kind of cause it is For example, the electric bicycle caught fire.
From the monitoring picture, 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 the influence of a small grenade”.
The person in charge reminded that when using electric bicycles at high temperature, first of all, you can’t charge them for a long time, as long as you ensure 80% power.
When replacing the battery, you must go to the original store (brand store).
It is best to replace the charger at the same time, because the voltage and current requirements are different.
When the mismatched charger is charged, it is easy to cause some battery faults.
The most important thing is not to take it home to recharge.
In case of an accident, the consequences at home will be more serious..
