[Abstract]: The "Guidelines for the Safe Use of Electric Bicycles" require that electric bicycles should be charged in a fixed parking and charging place that meets the national electrical safety regulations. Lithium-ion batteries should be placed in an open or semi-open dedicated charging place, and the maximum charging time should not be more than 8 hours each time. It is strictly prohibited to use temporary power lines, sockets and switches for charging.

  In recent years, my country‘s electric vehicle fire accidents have occurred frequently. China‘s fire protection data show that there are about 2,000 electric vehicle fires across the country every year, and 80% of the fires are caused by charging. At the same time, China Fire also reminded many times that the charging of electric vehicles must be safety first, and it is forbidden to enter buildings or fly-line charging. Recently, this requirement was put into the "Guidelines for the Safe Use of Electric Bicycles."

  According to the news released by the Beijing Municipal Bureau of Market Supervision, a few days ago, under its guidance, the Beijing Bicycle and Electric Bicycle Industry Association organized the industry to compile the "Technical Specifications for Lithium-ion Power Battery Packs for Electric Bicycles", "Technical Specifications for Chargers for Electric Bicycles", The three group standards of the "Guidelines for the Safe Use of Electric Bicycles" were officially released. It is reported that this is the first release of similar standards in the local electric bicycle industry.

  Among them, the "Guide to the Safe Use of Electric Bicycles" guides the safety requirements that electric bicycle users need to meet in daily links such as purchase, use, parking, charging, and maintenance, and provides standard guidelines for the safe use of electric bicycles.

  In terms of parking, the "Guide" points out that electric bicycles should be parked in open or semi-open dedicated parking places, and should not be parked indoors and in evacuation passages and safety exits of buildings. When parking, the power lock should be turned off, and the power should be turned off to park. Special attention should be paid to the fact that electric bicycles should be parked far away from dangerous places such as gas facilities, power distribution facilities, boiler rooms, gas stations, and the distance between them is greater than 5 meters. It should be parked far away from the outer wall of the building, and no combustible materials are piled within 2 meters around the body. Avoid parking in the upper ground position of sewage wells, sewers, septic tanks and other areas.

  In terms of charging, the "Guide" also makes clear requirements. Electric bicycles should be charged in a fixed parking and charging place that meets the national electrical safety regulations. Lithium-ion batteries should be placed in an open or semi-open dedicated charging place, and the maximum charging time should not be more than 8 hours each time. It is strictly prohibited to use temporary power lines, sockets and switches for charging.

  Two group standards, "Technical Specifications for Lithium-ion Power Battery Packs for Electric Bicycles" and "Technical Specifications for Chargers for Electric Bicycles", focus on the naming of battery models and the permanent unique code identification of battery packs, charging and discharging based on market needs and regulatory requirements. The interface anti-electric shock protection, battery pack installation battery management system (BMS), and electrical output interface safety, charger classification and charger protection level have been clearly required, which fills the safety technical requirements for lithium batteries and charger products for electric bicycles Whitespace.

  The Beijing Municipal Bureau of Market Supervision stated that the formulation of the above-mentioned group standards provides clear technical guidelines for production, sales and users. In order to promote the quality upgrade of electric bicycles and supporting products, promote the healthy development of the industry, improve the service level of enterprises, and the comprehensive management of the electric bicycle industry is of great significance.
