Recently, the mandatory national standard "Technical Specification for Mobile Power Bank Safety" (draft for soliciting opinions) was officially released on the website of the Ministry of Industry and Information Technology from November 12th to December 11th. Compared with the old standard, the new national standard proposes dozens of strict improvement requirements in the three major technical fields of the whole machine, circuit board, and battery cell, known as the "strictest" safety standard for power banks in history, which has attracted widespread attention. Why establish a new national standard for power banks? What impact will the new national standard have on consumers? The reporter interviewed relevant experts on this matter. First question: Why is it necessary to establish a new national standard for power banks? Since the beginning of this year, there have been frequent safety issues with power banks, such as the explosion of multiple brands, the "recall wave" of well-known products, and the Civil Aviation Administration's ban on passengers carrying non 3C marked power banks on board. According to statistics from the China Academy of Civil Aviation Science and Technology, there were 15 incidents of passengers carrying power banks catching fire and emitting smoke on airplanes in the first half of the year, which is about double the same period last year. China is the world's largest producer and consumer of power banks. The safety of power banks affects everyone, which is an important background for the introduction of the "strictest" standard in history. The person in charge of the standard preparation working group stated that the frequent occurrence of mobile power supply safety accidents in recent years has exposed problems such as uneven product quality and numerous safety hazards, especially in public places (such as airplanes, subways, shopping malls) or during user carrying. This not only highlights the differences and particularities between mobile power products and other electronic products, but also poses a threat to the safety of consumers' lives and property. The person in charge stated that the development of standards will provide technical basis for mobile power management, clarify technical thresholds, and reduce accident risks from the source. At the same time, we will improve product quality, curb the proliferation of inferior products, eliminate low-quality production capacity, and ensure the safety of consumers' lives and property. The new standard will complement and complement the two mandatory national standards and one recommended national standard already published in the field of mobile power banks. Question 2: What new requirements does the new national standard propose? Compared to existing standards, the new regulations propose breakthrough requirements in core areas such as the entire machine, battery cells, and circuit boards. The draft for soliciting opinions proposes that in terms of labeling, the new regulations have changed the previous practice of only labeling the brand, and explicitly require that product casings must be labeled with information such as product name and model, battery material system, production date, and recommended safe use life. The new standard adds or enhances testing requirements for overcharging, needle punching, squeezing, thermal abuse, etc., and requires that mobile power supplies must "not ignite, explode, rupture, or leak" in situations such as overcharging discharge, short circuit, overload, and misoperation. The new standard also includes requirements for intelligent monitoring and management of mobile power banks. Among them, intelligent monitoring information includes battery voltage, temperature, current information, abnormal voltage, abnormal temperature, etc. The standard requires that the above information must be recorded in the chip and read by all users. In terms of intelligent management, the standard requires that mobile power banks should have an intelligent management system, with functions such as dynamic management of charging and discharging currents, over temperature protection, etc., to ensure the safety of the entire lifecycle of lithium-ion batteries. Question 3: Will consumers' purchased power banks be affected? The person in charge of China Electronics Standardization Institute stated that the implementation time of the new standard has not yet been determined. According to convention, the transition period after the release of mandatory national standards is generally 6 to 12 months, and the standard will be implemented after selecting a suitable transition period based on suggestions from all parties. The standard is currently in the stage of soliciting opinions and has not been finalized yet. The person in charge clarified that according to existing policies and regulations in China, mobile power products purchased by consumers that have obtained 3C certification will not be affected by the release of standards and can continue to be held and used. In daily use, Geng Zhenfeng, director of the Battery Research Laboratory at the Safety Center of China Electronics Standardization Institute, reminds consumers not to place their power banks on the front windows of cars that are exposed to sunlight in summer, and to avoid being bitten by pets at home, as well as frequent throwing and falling of power banks. When placed in a bag, avoid strong squeezing with other items, tools, etc. to prevent safety risks. (New Society)
