Knock the alarm bell again!Send two fires in three days in a row, don't stop the room in the motorcycles

Within three days, there were two consecutive fire alarms related to electric bicycles in Guangzhou. Fortunately, they all occurred outdoors without causing casualties. The reporter learned from the fire department on July 6 that the preliminary survey of the fire of the outdoor electric bicycle charging station in Baiyun District showed that the source of the fire was a takeaway food delivery electric bicycle.

In recent years, electric bicycle fire has become a typical field of fire safety risks. Why do electric bicycles frequently cause fire? How to prevent such fires? Experts from the fire rescue detachment of Guangzhou Fire Rescue Division answered questions for the general public.

【Fire Police Review】

July 4: Outdoor electric bicycle charging station on fire

Electric bicycle fire becomes a typical field of fire safety risks

In December 2021, the law enforcement inspection team of the Standing Committee of the National People's Congress on the Implementation of the Implementation of the Fire of the People's Republic of China pointed out that the emerging risks and challenges faced by the current fire protection law are electric bicycles, new energy vehicles, hydrogen energy, energy, and energy, and energy, hydrogen energy, energy, and energy, and energy, hydrogen energy, energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy, and energy. Fire explosions such as photovoltaic and lithium power storage facilities, natural gas leakage and large storage and logistics venues are growing. Among them, typical areas are electric bicycle fires.

The report revealed that my country's electric bicycle has more than 300 million vehicles, the output is still growing rapidly, and the risk of fire risks has increased sharply. From January to October 2021, there were more than 14,000 fires caused by electric bicycles and its battery failures across the country, 41 deaths and 157 injuries.

The maintenance, modification, parking, and use of electric bicycles, as well as the management of the charging, scrap and recycling of lithium batteries, and the problems such as illegal modification, household charging, excessive use, and battery aging, and breed a large number of hidden safety hazards. In particular, due to insufficient outdoor charging piles and uneven charging prices, the problem of household charging is more common.

【Typical Case】:

Modified the tragedy of the brewing privately, four years of trial!

According to the Fire Rescue Bureau of the Emergency Management Department, a few days ago, the People's Court of the Fumian District People's Court of Yulin City, Guangxi Zhuang Autonomous Region sentenced to the first instance of the "10.5" fire accident in Xinqiao Town, Fumian District: The defendant Wu Mouhai caused a fire due to faults, causing the two to die The property lost RMB 27,447, and its behavior has constituted a fire. In accordance with the "Interpretation of the Criminal Law of the People's Republic of China" and the "Supreme People's Court on the Specific Applied Laws of Specific Applied Laws" in accordance with the Supreme People's Court.

On October 4, 2021, the defendant Wu Mouhai purchased an electric vehicle lithium battery with a power of 66AM on the Internet and installed it on its own electric vehicle.

At 2:6:00 on October 5th, Wu Mouhai charged the above -mentioned electric vehicles with unsuitable chargers on the first floor of Chen Moumou's residence on the first floor of Chen Moumou's residence in Xinqiao Town, Yulin Fulin District. At 3:44, the charging electric vehicle lithium battery heat out of control and burst of fire caused fire. The fire burned 10 electric vehicles and one motorcycle, causing 1 child and 1 child to be killed.

Why does electric bicycle fire happen frequently?

Recently, in Lishui, Zhejiang, an electric bicycle suddenly caught fire when it was charged on the street. There were more than 20 fire extinguishers nearby nearby, and the fire was still unable to completely extinguish the fire until the firefighters rushed, using a water gun to extinguish the fire, and put the lithium battery dismantled into the water to continue to cool down.

"It is conceivable that if it happens indoors, the consequences are unimaginable." The fire department reminded that when lithium batteries fire, a large amount of water will need to cool down the fire. The dry powder fire extinguisher can only extinguish the surrounding fire, and it cannot effectively prevent the lithium battery from the heat of the lithium battery. "The frequent frequent fire accidents of electric bicycles are mainly due to the quality problem of the battery itself and the poor charging habits, which leads to the overheating and short circuit of the battery, which causes the fire." Fire -adjustment experts introduced that the lines of the line, the short circuit of the line, the lack of water in the battery, and the imbalance of the battery pack. , Battery material problems, etc. are the cause of fire in electric bicycle fires.

Data show that in response to the electric bicycle fire in Guangzhou in 2021, from the cause of fire, battery failure is the main cause of electric bicycle fire, accounting for 80.85%of the total number of electric vehicle fires; It accounted for 29.55%of the total number of electric bicycles, and also accounted for 10.96%of the total number of fires in residential venues.

In addition, according to incomplete statistics, 50%of electric bicycle fires occurred during non -charging. In the case of electric bicycle fire causing casualties, 90%occurred in the hall, aisle, and stairwells. Most electric bicycle fires occurred during night charging. During this time, people were often sleeping. difficulty.

How to prevent electric bicycle fires?

From July this year, the newly revised "Measures for the Implementation of the People's Republic of China" of the People's Republic of China was officially implemented. It clearly stipulates that it is forbidden to park electric bicycles, electric motorcycles, or electric motorcycles, or charging electric bicycles, electric motorcycles and batteries in indoor places that do not meet the fire safety conditions; It is forbidden to carry electric bicycles, electric motorcycles and its batteries into the elevator car.

"The most effective rescue is prevention." Guangzhou Fire reminds the general public to choose the product produced by regular manufacturers, and secondly requires good electric bicycles to ensure safety: electric bicycles should charging charging piles in the community, charging charging, charging charging, charging, and charging After completing the plugs in time; if you charge the non -flying wire, use a fixed socket, one charging; the charging time should not be too long, the continuous charging for more than 12 hours or the charger is unqualified, it can easily lead to short circuit and spark.

"It is particularly needed to remind you, please strengthen your daily self -inspection and self -control, and don't blindly modify the electric bicycle." Fire -adjustment experts said that if electric bicycles are used overdue, the electrical lines and batteries will be aging and short circuit. Lighting or installation of batteries can easily cause the line overload and cause fire. In daily life, citizens should strengthen inspection of electric wires, circuits and other aspects of electric bicycles to prevent the contact point of contact with poor contact, avoid short circuits and string of electricity due to the aging of the line, wear, and strings.
