With the rapid development of electric bicycles, the problem of charging and replacing batteries has become increasingly prominent.

At the recent "Symposium on Practice and Reflection on Urban Layout of Two-wheeled Charging and Swapping Equipment" hosted by the People's Political Consultative Conference Network, experts participating in the meeting believed that in recent years, the safety of two-wheeled electric bicycles has been learned from the blood, and the society has paid great attention to it. The "replacement charging" model is preferable, which can solve the safety problems of residents' traditional private piles, home charging, and flying cable pulling power. Through professional enterprises' unified charging and replacement services, system intelligent safety monitoring methods, etc., it can effectively solve the problem of residents' self-charging. safe question.

  Data show that there are more than 700 million two-wheeled non-motor vehicles in the country, which is equivalent to 1 non-motor vehicle for every 2 people.

Among them, electric bicycles are becoming more and more popular.

As income growth makes residents tend to choose high-quality and powerful means of transportation, and motorcycles are restricted in many cities, more and more residents choose to buy electric bicycles.

According to statistics, the number of electric bicycles in my country has exceeded 300 million.

  In recent years, due to the frequent occurrence of electric bicycle fire accidents, causing serious loss of life and property safety, the whole society has formed a consensus that electric bicycles should not be charged upstairs.

The "Regulations on Fire Safety Management of High-rise Civil Buildings", which took effect on August 1, 2021, explicitly prohibits parking or charging electric bicycles in public halls, evacuation walks, stairwells, and safety exits of high-rise civil buildings.

Various provinces have also issued local regulations one after another, making strict requirements for electric bicycles to go upstairs.

  Zhang Xingkai, president of the China Academy of Work Safety, said that the safety of electric bicycles is indeed a "small incision, a big people's livelihood", which is related to the safety of people's lives and property and their vital interests.

From the survey in recent years, the fire and explosion of electric bicycles have shown a rapid upward trend.

  "The stock electric bicycles have different old and new standards and different degrees of aging. The battery quality is not good enough, and it is uncontrollable during the charging process. This is the main reason for the fire of electric bicycles." In the view of Zhou Jinxiu, vice president of Hello Travel and dean of the research institute , It is extremely difficult to supervise these old and over-standard private electric bicycles.

  At present, the national solution is to build charging piles in the community, but such a solution cannot solve the problem of the source of the fire of the electric bicycle during use or charging.

Liu Yongdong, deputy secretary general of the China Electricity Council, believes that it is impossible to monitor the charging status of the battery in real time in the charging mode because there is no communication protocol.

In addition, all electric bicycle charging socket standards are now civilian standards.

"Household sockets are designed based on home scenarios and do not need to be plugged in and unplugged every day. The application scenario of charging two-wheeled electric bicycles is a public environment, and there is a problem of incompatibility."

  Liu Yongdong suggested that to monitor the charging process, the battery characteristics, charging and changing cabinet information and enterprise platform information must be connected.

He called on the relevant departments to establish a supervision platform, unify the data on the supervision platform, solve the problem of state safety monitoring of batteries, and issue relevant standards for information interconnection.

  "The production and safe use of two-wheeled electric bicycles have to pass three hurdles: intrinsic safety, use safety, and policy promotion." Wang Xianjin, member of the National Committee of the Chinese People's Political Consultative Conference and vice president of the Academy of Sciences of the Ministry of Transport, said, first of all, at the source Ensure the product safety of vehicles, batteries, and charging and replacing equipment.

Through technical research, product production, and quality standard control, the safety of the source is guaranteed.

Secondly, the daily electricity consumption and charging and replacement services of two-wheeled electric bicycles should be included in the basic social public services, and practical problems such as urban layout, site use, electricity price inclination, and cost allocation should be included in the formulation of public policies and the level of supply guidance to speed up the resolution.

  At the current stage of market development, the "recharge with replacement" model has been accepted by large-scale shared moped companies, a wide range of urban commercial distribution groups and some urban residents.

The two-round power exchange service of "recharging with replacement and separation of vehicle power" provided by the enterprise can reduce the burden of urban fire safety management through 24-hour real-time intelligent safety monitoring and platform-based management operations of batteries and power exchange points Residents in urban communities have problems such as difficulty in charging, slow charging, and unsafe charging.

  Chen Chen, head of the special class for the construction of centralized charging facilities for electric bicycles in Beijing, introduced that by comparing the charging piles, charging cabinets and power exchange cabinets that are often seen in the market in terms of safety, convenience and economy, the preliminary results were obtained. Conclusion: It is suitable to give priority to the promotion of power exchange cabinets in commercial buildings and distribution centers for takeaway express delivery, and the construction of charging piles as a transitional measure is suitable for places with insufficient space in public areas such as old communities and bungalows.

  According to Wang Zheng, vice president of Xiaoha's battery swap technology, the flexible and complementary model of "charging + swapping" will continue to become the development direction of urban two-wheel travel energy supplementation for a period of time.
