Electric bikes
It greatly facilitates daily travel
But it may bring security risks
It should not be overlooked
Recently, two electric vehicles caught fire at home charging
It has aroused widespread concern
According to Changjiang Cloud News
July 9, Wuhan, Hubei
A fire broke out in a rental house
led to a junior student Xiao Du
More than 90% of the whole body burns
More than 900,000 yuan has been spent on rescue treatment
According to Xiao Du's father, during the summer vacation
The son and another junior boy in the same school, Xiao Li
I worked part-time in a shared house near the school
On the evening of July 8, Xiao Li rented an electric car battery
Mention room charging after removal
I didn't expect it to be around 6 o'clock in the morning on July 9
The battery has deflagrated
It is reported that the cause of the fire was comprehensively identified
Thermal runaway occurs during lithium battery charging
Ignite the surrounding combustibles and cause a fire
According to Guangdong fire news
At about 2 a.m. on August 26
A fire broke out in a villager's self-built house in Shanwei City
Firefighters learned
The building that caught fire was a 4-storey self-built house
The fire started in the stairwell on the first floor
According to the situation on site
Firefighters pass through the first-floor window with a water cannon
Extinguish stairwell fires
At the same time, the trapped people were instructed
Shelter from the smoke in the room on the second floor, and wait for help
After more than 20 minutes of rescue
The open flame was controlled
Two trapped people were rescued
There were no casualties
After preliminary investigation, it was determined that the cause of the fire was
E-bikes parked in the stairwell on the first floor
Thermal runaway of the battery causes a fire
Experiments with Apocalypse
This experiment simulates that when the electric bicycle is charged at home, when the lithium battery is overcharged and heated, it cannot dissipate heat in time within 3 minutes, and the organic matter inside the battery melts and shrinks, which then causes the positive and negative poles of the battery to be short-circuited, and finally the battery short-circuit explosion. Three minutes after the fire, the e-bike had been burned to the "skeleton".
Once the battery explodes, ignition of the surrounding combustibles will make the fire spread rapidly, and the harmful gases and smoke produced are difficult to discharge, which seriously threatens the life safety of personnel.
Ah-pop tips
Data shows that 80% of electric vehicle fires occur while charging, and 90% of fire casualties occur in hallways, aisles and stairwells. For the safety of you and others, please do not push the electric vehicle indoors to park and charge.
