Quality Supervision: Mobile power supply common false standard part of the test fire

With the popularity of mobile digital electronic products such as smartphones, tablet computers, digital players, and the frequent application of apps, the problem of "battery short board" caused by insufficient battery endurance is becoming more and more prominent. Therefore, mobile power (commonly known as charging Bao) this kind of portable external power supply equipment gradually popular market. But at present, the quality and safety risk of mobile power products is higher, Shanghai Quality Supervision Department held a special conference today, pointed out that the fire, burst, nominal capacity of the virtual standard can not meet the normal charge of many problems. Click the picture to view the video dozens of Yuan mobile power "flooded" the field more than a fire spontaneous combustion from a few to hundreds of yuan, mobile power in the electricity and digital market everywhere, and the market demand is quite large. Reporter yesterday in Taobao input mobile power keyword found that the total number of products unexpectedly up to nearly 700,000 pieces of baby. And the price of 50 yuan below the mobile power supply has nearly 50,000, including the capacity of up to 50000 ma large capacity equipment, its brand is also a variety of, in the network can not find the company's effective information. A "genuine perfume flavor Samsung, HTC, iphone mobile phone mobile power 2600 ma rechargeable PO/device" products sold only 6 yuan, its security can not help but let people doubt. It is worth mentioning that, August 6 this year, Nanjing, Miss Wang carry-on bags in the mobile power suddenly caught fire; June 23, Beijing subway line Line 10, a passenger in the package mobile phone power supply spontaneous combustion ... Recently, mobile phone mobile power security incidents frequently. Therefore, the mobile power product quality is uneven, the industry safety standards are missing, but also was placed on the table. Recently, China Communications Industry Association president Bingke in China Mobile Power Security Symposium has revealed: "The quality of mobile power standards or the second half of the release, poor quality mobile power supply is expected to be resolved." "Well-known channels to sell products hidden dangers of the municipal Quality Supervision Bureau issued a security risk early warning of the Municipal Quality Supervision Bureau released today, the 5th product quality and safety risk warning display, the phenomenon of virtual standard rated capacity is common in mobile power supply, and some products even have fire and burst in test, which may threaten the personal property safety of users. Of the 22 batches of mobile power samples sampled, 41% of the samples were taken on e-commerce sites. Inspection and evaluation based on the approval of the expert review of Mobile power product testing program, test methods and technical requirements are mainly referred to GB/T 18287-2000, "the general specification of lithium-ion batteries for cellular telephones" and GB/t 17626.2-2006 "Electromagnetic compatibility test and measurement technology electrostatic discharge immunity test" Development, inspection items include: Rated capacity, electrostatic discharge immunity, environmental adaptability (free fall), security performance (overcharge protection, over discharge protection, short circuit protection), battery safety requirements (heavy impact, thermal shock) and other general safety projects. The test results show that 13 batches of samples do not conform to the specified value of the above standard, and account for 59% of the total sample number. In addition, there are 9 samples of the core measured capacity below the overall "nominal capacity", vacancies ranging from 1% to 37.8%-AlsoThat is, the most serious sample of short, its battery capacity than nominal value shrunk by nearly 40%. This also means that consumers who use such products are unable to meet the normal charging requirements when charging for digital products, and they lose the meaning of the mobile power supply. Municipal Quality Supervision Bureau: appeal to national standard to avoid long charge according to the statistical analysis of the results of the test, taking into account the severity of the risk and the possibility of risk, by experts assessment, mobile power products, quality and safety risk rating is rated as "more serious", need to attract sufficient attention. Municipal Quality Supervision Bureau deputy director Shen Wei-min said, has recommended relevant departments as soon as possible to introduce relevant national standards, standardize the mobile power industry. For the existence of quality and safety risks of products, the municipal Quality Supervision Bureau has urged the relevant enterprises to take the initiative to withdraw products. "It needs to be emphasized that in the absence of national standards, the industry standard, enterprises should refer to the corresponding general safety indicators of technical requirements, as soon as possible to establish and implement enterprise standards, strengthen raw material procurement, production processes and factory inspection management, take effective measures to eliminate or reduce product quality and safety risks." Foreign provinces and cities to produce products, has been notified the location of the quality supervision departments. "Shen Wei-min said. Municipal Quality Supervision Bureau at the same time prompts the vast number of consumers, buy mobile power to try to choose the normal channel to buy, do not buy in the source of dubious channels. In the use of mobile power, refer to the instructions to use the correct way to avoid long time charging, and keep the product stored in the dry place, away from flammable and corrosive materials. Do not disassemble, impact, throw into the fire or water the mobile power supply. When used away from high temperature, fire, such as the discovery of battery bulging, leakage or odor, to immediately stop using.
