recently, China's first national standard for mobile power - the "General Specification for Portable Power Supplies for Information Technology Portable Digital Equipment" officially promulgated by the People's Republic of China, was promulgated jointly by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and China National Standardization Administration, July 1, 2018 formally implemented.
Preparation of national standards for mobile power
Mentioned the preparation of the national standard mobile power, in fact, as early as 2015 put forward the mobile power security assessment system, and has been carried out in the certification body for mobile power security voluntary certification widely implemented, the mobile power of the national standard The official release, to further clarify the safety requirements of such products, product stereotypes, quality supervision will be more evidence-based.
Mobile power unit of the drafting of national standards
Many standard drafting units, many of them many from Shenzhen, the first-tier cities in this industry enterprises, such as Shenzhen Huntkey Chi Yuan Electric Co., Ltd., China Great Wall Computer Shenzhen Co., Ltd., Shenzhen Di Bike Electronic Technology Co., Ltd., Guangdong Electric Second Technology Co., Ltd., Huawei Technologies Co., Ltd., Yan Wanda Electronics Co., Ltd., Shenzhen City Best Power Co., Ltd. and so on.
Mobile Power National Standards details
The standard text includes: Scope of application, normative references, terms and definitions, requirements, test methods, quality assessment procedures, marking, packaging, shipping and storage and other parts.
The national standard for mobile power stipulates the requirements, test methods, quality assessment procedures and marking, packaging, transportation and storage of mobile power supplies for portable digital equipment (hereinafter referred to as 'mobile power supplies'), norms applicable to portable digital equipment with input voltage not greater than 250V, the output DC voltage is not greater than 60V, single-port output current is not greater than 5A, the use of wired output of mobile power.
First of all, the standard defines the definition of various terms, such as: Mobile power refers to a non-stationary power system that is composed of a battery or a battery pack, a corresponding circuit and a housing and can provide a stable DC output, and does not exceed 18 kg of a predetermined user-portable power supply.
Second, make specific and specific requirements on all aspects of the mobile power supply, including: appearance marking, performance, safety protection, safety, electromagnetic compatibility, environmental adaptability, limited use of substances and so on.
such as Mobile power cycle life should not be less than 300 times, the product must have an overshoot protection, over-discharge protection, short circuit protection, overload protection, misoperation protection.
National standards for mobile power will be used as a basis for spot checks
Guangdong Provincial Bureau of Quality Supervision directly under the Guangdong Provincial Quality Inspection Institute and the drafting of national standard electricity second, Meizu, Patriot, Bester, Dubico communication will be combined with a number of mobile power GB drafting unit and charging head network to promote the new GB's publicity work, at the same time, according to the introduction of Guangdong Quality Inspection Institute, the future national and provincial mobile power checks will also adopt the new national standard.
