Minsheng Direct Cars 丨 Average monthly electric bicycle how to prevent "burning"

  Xinhua News Agency, November 9th: Average monthly electric bicycle how to prevent "" "Xinhua News Agency reporter violations, flying line charging, illegal modification," super-service "…Convenient, economical electric bicycle, it is necessary to hide a variety of fire hazards. This year, there have been more than 10,000 electric bicycles in the country since this year and causing casualties.

Average thousand of fire accidents per month, reflecting urgency, severeity, and complexity of electric bicycle fire safety governance.

  How to prevent electric bikes to prevent "ignition"? This reporter conducted a survey. Electric bicycle fire accident Frequency Frequency May 10 Not long ago, Beijing’s fire accident once again triggered the attention of the whole society on electric bicycle fire safety. In the early morning of September 20th, Zhang Moumou, a community tenant of Tongzhou District, Beijing, brought electric bicycle batteries to indirect fire, causing 5 people to die, lessons were very painful. On the day before yesterday, Hefei City has an accident that caused fire when electric bicycles are charged at home.

On the evening of November 7, the electric bicycle in a small area of ??Hefei City burned when charging in the house, causing fire. Fortunately, firefighters extinguished in time, did not cause big losses and casualties.

  As the number of electric bicycles continued to rise, the related fire explosion accidents showed multiple trends. In the case of Jinan, Shandong, as of September 2, Jinan City listed electric bicycle has reached more than 300,000, this year, the city’s police officer is 51 electric bicycle fires, including 28 of which fired on fire, and 17 of the fire during use. rise.

  In Zhejiang, there are about 25 million units of registered electric bicycles.

According to the local fire department statistics, the fire safety accident caused by electric bicycles in the nearly three years reached 1861. Looking at the country, in recent years, my country’s electric bicycle has sold more than 30 million units, and the social guarantee exceeds 300 million. According to the Emergency Management Department’s fire rescue bureau, there have been more than 10,000 electric bicycles in the country since this year and causing casualties, showing that there is still a shortest point and pain point for electric bicycle fire safety governance. Production and sales use the fire hazards in the risks of all the risks, and the electric bicycles have repeatedly occurred in the back of fire accidents, there are many hidden dangers in the unqualified product technology, illegal modification, and irregular charging irregularity. – Electric bicycle itself does not meet the standard or exceeded the standard. Some manufacturers have saved costs, unauthorized chargers, unqualified production quality, did not use corresponding wires as required, and did not properly install protection, and unreasonable assembly process is unreasonable, and it is easy to trigger fire safety accidents.

  - The sales market provides electric bicycle battery modification business. In order to meet the needs of some users, some informal manufacturers or individuals will refine the battery privately, and to save the battery protection rack, reduce the anti – collision of the battery, and increase safety hazards. The reporter randomly visited several electric bicycle shops in Hangzhou. Many shopkeepers said that they can add more capacity batteries for electric bicycles. "The expanded battery is actually a larger number of timed bombs." The technical experts of Hangzhou Fire Rescue Detachment said that these privately modified batterions are difficult to guarantee in order to reduce costs, and the probability of accidents is also Double growth.

  - Electric bicycle charging irregularity.

At present, electric bicycle parking and charging problems have always been a pain point for governance. According to a plurality of cells in Hangzhou, many of the owners ride their electric bicycles directly to their entrances, or take the battery back to charge the battery, which actually has a great security risk. "The battery will produce a large amount of heat during charging. If the internal temperature is continuously increased or the temperature between the monomer batteries is uneven, there will be a risk of overheating and 上海贵族宝贝官网 explosion." Zhejiang’s battery manufacturer technician Wu said.

  It is necessary to prevent the problem of "burning" and need to have some problems in the above problems. All localities have also successively explore technical means to control electric bicycle fire safety hazards.

  Zhejiang system integrated supervision department, market main body, product quality and other multi-data information, constructing electric bicycle governance digital system "Zhejiang E line online".

Starting from production, sales, registration, riding, charge, repair, and recovery, realizing the comprehensive management process reconstruction, management reconstruction and system remodeling of electric bicycle full lifecycle.

In some cells in Shandong Weifang City, the camera 上海海选油压会所 inside the elevator recognizes that there is an electric bicycle entry, it will automatically trigger the flash alarm and issue a voice prompt. At the same time, the elevator will temporarily stop running.

  Eliminate fire hazards in electric bicycles, the electric bicycle industry also needs to be upgraded.

Relevant experts said that it is necessary to continue to promote electric bicycle process innovation and form safety standards. Manufacturers should strictly enhance quality control, and strengthen safety detection for electric bicycle components, in particular electrical components, limit the maximum current of the line, and increase short circuit protection for chargers.

  At the same time, the "Regulations on the Fire Safety Management of High-Level Civil Buildings" on August 1, 2021 clearly stipulates that there is no electric bicycle 老闵行江川路浴场150 in the high-level civil construction public hall, evacuation walkway, stairwell, and safe exports to charge electric bicycles.

  The new rule has been implemented for 3 months, but the reporter survey found that many places were not in place for the implementation of management regulations, and the electric bicycle entry is still universal.

  "The next step will continue to strengthen the source management and comprehensive management, promote more parking, charging places, follow-up and exporting fire safety standards, promote the implementation of electricity price preferential policies to implement fixed charging places, and use electricity for public safety standards Bicycle provides better guarantees. "Director Qiong, Director of the Fire Revision Bureau of the Emergency Management Department," At the same time, guide the property management unit to strengthen inspection and inspection, and stop illegal violations in time.
