Low quality charging safety accidents occur frequently

According to CCTV's "Weekly Quality Report", this year, the State Administration of Quality Supervision, Inspection and Quarantine organized the monitoring of product quality and safety risks of mobile power sources(commonly known as "charging treasures"). The 32 batches of products collected from the market have quality and safety risks through the detection of heat abuse, overcharging, short-circuit and other items. There is a counterfeit Xiaomi mobile power products explosion incident, has caused widespread concern, mobile power security concerns. How to eliminate the hidden danger of mobile power supply and protect the interests of consumers is an urgent problem that needs to be solved.

Mobile power quality and safety have far-reaching implications

The safety accident that breaks out repeatedly, make our country mobile power supply and lithium battery industry benign development situation faces crisis.

The State Administration of Quality Supervision and Supervision found that the problems of mobile power supply include: virtual standards of capacity, too low or too high output voltage, non-flame retardant plastic shells, and heavy impact can cause fire or explosion. These safety risks not only exist, but have also caused many safety incidents.

This year, a number of low-quality "charging" safety accidents have been reported in the newspapers, including airports, subways, factories, homes and student dormitories. Consumers 'personal and property safety risks are everywhere.

Mobile power is an important application market for lithium battery products in China. The lithium battery produced in China can meet the demand of mobile power, and the price is lower. About 50% of the global mobile power supply and the batteries used by it are supplied by China. China has become the leading force in the mobile power market. Repeated security incidents have caused the vicious development of China's mobile power and lithium battery industry to face a crisis, and the reputation of domestic brands has fallen sharply. For example, Huawei's 5200mAh mobile power supply has been imported from Sanyo and Sony to ensure product safety. On the other hand, it provides opportunities for foreign companies to take advantage of. 18650 battery manufacturers, due to the sharp decline in orders in traditional markets such as notebook computers, its huge capacity needs to find a way out, such as Samsung's 2.2Ah 18650 battery required to significantly reduce the price of mobile power this year, trying to seize the global mobile power at a more favorable price. Market, squeeze our enterprises. The frequent occurrence of safety accidents affects the long-term development of China's lithium battery industry.

In recent years, overheating, flammability, explosive and other "charging treasures" have become more and more dangerous, and various cottage products have flooded the market, leading to a crisis of consumer confidence that has risen from a single product level to the government level. The discussion has intensified and criticism of the regulatory approach has been heard. The first is to simply rely on "checking, blocking, penalizing, and shutting down" to solve the problem. The effect is only a drop in the bucket, and the standard is not a cure. It must be dealt with from the production process to strictly control the source. Second, in some important places, such as the Capital Airport, there are more than 100 mobile power sources that are intercepted and abandoned by passengers every day. There are thousands of mobile power sources in airports around the country. A large number of abandoned mobile power sources, including "three no" and inferior products, storage and handling have serious security risks, to test the government.

Frequent safety incidents reveal multiple problems

China's production, quality, security separation of the management system, resulting in mobile power safety supervision loopholes.

Due to the lack of mobile power standards, the entire industrial chain from raw materials to semi-finished products, the production process of finished products is not standardized, and the quality of products is uneven and poor.

First, mobile power product standards have not yet been introduced. Mobile power sources are integrated with power storage, voltage lifting, and charging management. The products that are closest to their functions are batteries and chargers. China has more than 20 national standards for batteries and national standards for chargers GB4706.18-2005 "Special Requirements for Safe Battery Chargers for Home and Similar Appliances", which are not fully applicable to mobile power sources.

Second, the mobile power supply inspection standard is missing. Mobile power sources such as a small "electrical", internal power indicator, core protection, charging management and rising power supply and other sets of circuits. The test standard involves many modules such as batteries and whole machines. At present, there is no comprehensive document to incorporate the relevant test standards into a standard. It simply applies the relevant standards of batteries and chargers for testing. The standard system of mobile power supply needs to be established.

There is a vacuum in mobile power safety supervision. China's production, quality, security separation of the management system, resulting in mobile power safety supervision loopholes. Under the current system, mainly in the quality management link, the State Administration of Quality Supervision, Inspection and Quarantine conducts regular spot checks to monitor the quality and safety risks of products, and there are blind areas in the production and safety management link. The single supervision department is only concerned with its own "one-acre three-point land", and it relies excessively on performance tests conducted from the quality point of view and safety tests conducted by thermal abuse, overcharging, and short-circuit, and can not completely detect and eliminate the possible quality and safety risks of mobile power sources. Lack of systematic understanding of product quality and safety. First of all, there is no supervision in the production and manufacturing chain, and it is impossible to reduce safety hazards at the source. Mobile power is an industry that has almost no threshold. Stimulated by high profits in the past two years, many mobile phone makers, battery makers, lithium battery manufacturers, and even some small businesses that have no relevant industry experience have also piled in. Second, there is a lack of safety oversight of mobile power and lithium batteries. At present, there is no safety supervision department that is clearly responsible for the supervision of these two products, and there is no strict punishment and accountability mechanism. For some mobile power production enterprises that seriously endanger consumer safety, after becoming an established fact, the relevant departments only made a decision on fines, and the determination of liability was also relatively vague, resulting in this kind of "low-cost violation" being intensified, and the company had no fear.

The construction of a third-party inspection system for the quality of mobile power products is lagging behind. At present, the third party detection system and system for mobile power supply and lithium batteries have not yet been established, and it is also an important factor that affects the quality and safety of mobile power supply. First, China's production, quality and safety inspection departments and institutions, fighting each other, can not avoid the interests of all parties in the inspection work, may affect impartiality and objectivity. Second, because of the lack of testing standards and specifications, it is impossible to form a necessary mobile power supply inspection system, so that the rights and obligations of the testing agencies in the quality and safety inspection of mobile power products are unknown. The third is the poor professionalism of the testing mechanism. Conventional quality testing mechanism lacks knowledge of mobile power supply and lithium battery mechanism and safety risk points, and has professional ability testing mechanism lacks qualification. Fourth, testing technology still needs to be improved. The current detection department still uses the technology of testing mobile phone batteries to detect mobile power sources. Although this kind of detection technology can serve as a demonstration and warning to some extent, it does not meet the characteristics of the mobile power supply product itself.

Eliminate Mobile Power Security

Relevant departments should explore the establishment of cross-sectoral coordination mechanisms to reach consensus on major issues related to the security development of mobile power sources and lithium batteries.

First, speed up the development of standards system

To solve the quality and safety problem of mobile power supply in China, the relevant departments must speed up the construction of standard system of mobile power supply and lithium battery. First, we need to establish a scientific system of standards. The quality and safety standards for mobile power supply and lithium batteries should be formulated and promulgated as soon as possible, and should be refined into various sub-industries and key products. Second, we will establish and improve standards for production management. We will ensure the control of key safety points in the whole process from the production and manufacture of lithium batteries to the assembly of mobile power supplies, and advance the technology of design, materials and manufacturing. The safety and consistency of lithium-ion batteries should be solved. Third, taking advantage of China's extensive participation in the international lithium-ion battery standardization organization, China has actively promoted the internationalization of its lithium-ion battery standard system.

Second, improve the quality and safety regulatory system

Relevant departments should strengthen coordination and cooperation, explore the establishment of cross-sectoral coordination mechanisms, and reach consensus on major issues related to the security development of mobile power sources and lithium batteries. First of all, under China's existing production, quality and safety management system, the management responsibilities of each department are further clarified, and the responsibilities, rights, benefits and efficiency of each department are unified, so as to prevent the dislocation and dislocation of the supervision system. Secondly, through the inter-ministerial joint meeting on hazardous chemicals, an inter-ministerial coordination mechanism for the quality and safety of lithium batteries and mobile power sources could be established. Regular exchanges and coordination on the safety supervision of lithium batteries and mobile power sources could be carried out to enhance the ability of the entire regulatory system to cope with the safety risks of lithium batteries. Finally, we need to draw on the successful experience of developed countries, improve the safety recall system for lithium batteries and mobile power products, increase penalties for enterprises that violate regulations, raise the cost of violating regulations, and realize the transformation of enterprises from "ask me to do it" to "I want to do it".

Third, attach importance to the construction of a third-party inspection and testing system

Detection is an important part of quality and safety supervision of mobile power supply and lithium battery. Under the existing management system of our country, it is necessary to promote the development of lithium battery and mobile power supply industry, and to supervise the safety of lithium battery and mobile power supply. Therefore, the third party inspection system must be strengthened to ensure the objectivity and impartiality of testing. First, improve the design of the inspection system. Endows independent third-party organizations with the rights and obligations in the quality and safety inspection of mobile power sources and lithium battery products, and makes up for the deficiencies of government inspection agencies. Second, we will introduce and cultivate independent third-party inspection and testing institutions, strengthen supervision, credit certification and evaluation of third-party organizations, and the government and industry organizations should regularly authorize and certify the qualifications and scope of testing of third-party testing institutions. Strengthen the quality control of third party inspection. Third, strengthen international cooperation, actively promote mutual trust in inspection and testing results, and comprehensively promote the internationalization of China's inspection and testing system.

Fourth, we should strengthen the healthy development of our industries

The development of mobile power industry and lithium-ion battery industry in our country are mutually reinforcing, so we must pay attention to the importance of improving the quality and safety of mobile power products to enhance the overall competitiveness of these two industries. The first is to support the existing mobile power enterprises in China to cultivate safe and reliable mobile power products with independent brands. According to the development thinking of "integrating resources, concentrating strength, attaching importance to breakthroughs, and improving the whole", the overall competitiveness of mobile power supply in China is consolidated. Second, China's lithium battery enterprises are encouraged to integrate mobile power production enterprises, learn from the advanced experience of Samsung and other foreign companies, give full play to the role of the market in allocating resources, through vertical integration, to create a complete chain of lithium battery industry aircraft carrier enterprises. Third, we will establish an access system for lithium batteries in China. China's lithium battery industry should focus on quality and safety, and refer to the successful experience of the "Lead storage battery Industry Admission Conditions". We will raise the threshold for safe access to the lithium battery industry in terms of enterprise layout, production capacity, project quality, process equipment, production environment, environmental protection, safety testing, and certification, and push forward the increase in the threshold for access to the mobile power supply industry. Fourth, a special Research Fund for mobile power supply and lithium battery safety has been set up, focusing on key technologies for the industrialization of lithium battery materials that meet safety requirements, the manufacturing process for large-capacity batteries, battery assembly technology and smart battery management systems. Overall impact and improve mobile power quality and safety level.
