Cyclists and passers-by were horrified when a moving electric bicycle caught fire. Critical moment, a car more than 10 years of 70 - year - old man came forward to put out the fire. For the electric car spontaneous combustion, the old man said the car's internal line of the importance of the fuse (piece).

A moving electric car burst into flames

Bam! A loud noise below the buttocks, is riding the electric bicycle of Mr. Li startled. I looked down and saw white smoke rising from the battery under the seat. "The battery is probably dead. It's okay. The bike can still pedal." As he was in a hurry to go to work, Mr. Li didn't pay much attention to it. Bam! Battery parts again issued a sound, battery unexpectedly out of flames!

Afraid, Mr. Li stopped the car and jumped down. As the fire in the electric car grew, Mr. Li pulled out his cell phone and dialed 110 and 119.

At this time, it was yesterday at 8:20 xu, the accident site is located near the sports north street tan south intersection. Due to the rush hour, passing pedestrians and vehicles saw the fire after the electric vehicles are diverted. Passing through this newspaper reporter to see the situation, stop to remind pedestrians through safety. As the fire in the electric car gets worse, a strong smell of burnt air comes into the air.

The septuagenarian put out the fire alone

"Quickly find cloth fire, do not water! Mr. Li was at his wit's end when an old man came up to him and said. But looking at the electric car burning fire, Mr Li and passers-by who are afraid to approach.

Thinking of everyone's concern, the old man, who said he specialized in electric cars, hurried to the front of the car to check the situation. Though the fire was very big, the old man pulled a cloth from the basket of the train and beat it against the fire. Then, the old man put the electric car on the handlebars of the cotton to take off the cover, kept beating fire.

Five or six minutes later, the electric car fire gradually reduced. The man grabbed the handlebars of his electric vehicle and pulled it from the zebra crossing to the side of the road, allowing vehicles and pedestrians to pass through.

After towing the car to safety, the man continued to pat the car's embers with cotton gloves and scooped sand from the roadside flower pond. At about 0840 hours, the fire was put out. Looking at his black hands, the onlookers applauded.

The damage of the fuse caused the wire to short-circuit

In the old man put out the fire at the same time, fire officers and soldiers and huayaospecial stationspecial arrived at the scene.

The reporter learned that the old man named meng fuyi, 70 years old, is the capital of an electric car repair shop owner.

The battery was burned out, the tires were burned out, one of the pedals was missing. "this is not a brand car, I've been riding it all these years without a problem. "Mr. Li said.

Was able to take a closer look at the electric Meng Fuyi said, with more than 10 years of repair experience, he is pretty sure electric internal electrical wiring short circuit, lead to the lithium battery of the car on fire, due to the lithium batteries in the battery compartment airtight space, was then deflagration, then the other parts of the electric vehicle.

"The fuse on the car's fender is already broken and could easily cause a short circuit." The electric car's wires are connected to a protective plate with a fuse (sheet) that protects the battery from charging and discharging, meng said. If there is a problem with the fuse, the line will short-circuit even if it is parked, let alone on the road.

"The fuse [piece] is easily damaged." Meng fuyi introduced, in addition to the battery after violent collision, the battery for strong charging, fast charging is also easy to burn the fuse (sheet). The maximum protection current of fuse (sheet) of general electric vehicles is 5A (ampere), but at present, the charging current of common street quick charging stations is between 5-7a, which is easy to cause fuse (sheet).

"Some repair stands do not replace this component, but after removing the wire will be connected directly, although it will not have any impact for the time being, but without the protection device, it is easy to cause a short circuit. Meng fuyi said.

Use a quick charger as little as possible

Yesterday afternoon, the reporter to the provincial capital street part electric vehicle repair booth to carry on an investigation, discovered that the price is only two or three yuan's insurance tube (piece) is not good to buy, some repair vehicles said no goods, and a repair person said no insurance tube (piece) will not cause too big impact on the line.

Subsequently, the reporter and the street rapid charging station investigation. "This machine USES a lot of electricity," said a cold drink stall owner. One young man who has charged his electric car for 40 minutes says he doesn't think twice about the damage done to it.

After consulting the relevant departments, the reporter learned that there is no relevant national standard for street quick charging stations at present, and the quality of fast chargers is entirely controlled by the manufacturer.

Mr. Li said his electric car, though not repaired, had been charged several times at street quick charging stations. To this, meng fuyi reminds everybody, the safe tube of electric car (piece) damage must change in time, must not connect electric wire directly. At the same time, people should use a matching charger to charge the battery before going out, as far as possible to use a quick charging station. If for emergency quick charge, it is best to charge only 10 minutes, in order to avoid damage to the electric car line components and batteries.
