"You shouldn't put your electric car in front of your child to charge!"
Ms. Cai from Shangluo, Shaanxi Province, regretted it very much
Recently, an electric vehicle that was charging indoors exploded and caught fire
As a result, Ms. Cai's 7-year-old son and 9-year-old daughter suffered severe burns
The child's mother: "The electric car was charging and on fire, and I suddenly heard a sound at night, and when I ran over, the fire was already very big, and the child called my mother inside, and my heart was broken at that time." ”
Dad ran into the fire and rescued the two, but both siblings were unconscious at the time.
The child's mother: "The child burned at the time...... The child's father also came out in a coma, and after a long time, he coughed up a lot of black substance. ”
The child's mother: "It's all my fault, I shouldn't have put the electric car in front of the child to charge." ”
The doctor said: "The little boy's condition is slightly milder and there is not much life-threatening so far, while the little girl's condition is much more serious, even after the dangerous period, the little girl's hands have been severely burned, and she may face the risk of amputation or even disability in the future." ”
Electric vehicle fire accidents are frequent
The fire started only in the blink of an eye
Let's watch a set of experiments together
Learn how terrible an electric car fire can be
01 Experimental setup
The experiment was conducted in a laboratory in a multi-storey building, and the spread of the fire was reproduced in a real state.
The laboratory has five floors, and an electric bicycle is set up on the first floor to simulate its thermal runaway and cause a fire. Foam boards are set up on the 1st, 3rd and 5th floors to detect temperature and toxic gases on site.
02Experiment begins
After the start of the experiment, the e-bike battery continued to heat up for the first 16 minutes, and it could catch fire at any time.
03 Electric bikes are starting to heat up
An open flame appeared at 16 minutes and 23 seconds, white smoke came out 10 seconds after the fire, and black smoke came out 50 seconds later, and the firefighters at the scene used a handheld thermal imager to detect that the temperature above the body exceeded 650 degrees Celsius. One minute after the fire, the body burned violently and the battery continued to explode.
A chimney effect is formed at the scene, and the smoke spreads upward. Seventy seconds after the fire, the upper space of the atrium quickly filled with smoke and gathered heat at the top, and the scorching smoke ignited the foam on the 5th floor.
According to the on-site harmful gas detector, the harmful gas quickly accumulates and reaches its peak.
04 Experimental effect
The experiment showed the characteristics of rapid fire starting, large smoke production and rapid heating of electric bicycles.
It can be seen through the above experiments
The e-bike caught fire quickly
The battery is explosive
That's why it's been emphasized
