The National Standards Commission issued China national standards Announcement No. 32 in 2017, and published 1090 national standards, 4 national standard amendments and 51 foreign versions of national standards. Among them, the first national standard of mobile power (power bank) in China, GB / T 35590-2017, general specification for mobile power supply for information technology portable digital equipment, is officially released, which will be officially implemented on July 1, 2018.
GB / T 35590:2017 specifies the technical requirements, test methods, quality assessment procedures, marking, packaging, transportation and storage of mobile power supply for portable digital equipment. Especially for rated capacity, rated energy, environmental adaptability and safety. It will provide more accurate technical basis for subsequent product design and development, supervision and spot check, and transportation appraisal. Various terms are defined in the standard, and specific requirements are made for all aspects of mobile power supply, including appearance identification, performance, safety protection, safety, electromagnetic compatibility, environmental adaptability, limit of restricted substances, etc. For example, the cycle life of mobile power supply should not be less than 300 times, and the product must have over impulse protection, over discharge protection and short circuit protection to be tested by Chinese manufacturers.
1、 Standard content:
The main body of GB / t35590-2017 general specification for mobile power supply for information technology portable digital equipment includes: scope of application, normative references, terms and definitions, requirements, test methods, quality assessment procedures, marks, packaging, transportation and storage, etc. The national standard of mobile power supply specifies the requirements, test methods, quality assessment procedures, marking, packaging, transportation and storage of mobile power supply for portable digital equipment (hereinafter referred to as "mobile power supply"). The specification is applicable to portable digital equipment with input voltage no more than 250V, output DC voltage no more than 60V, single port output current no more than 5a, and mobile power supply with wired output mode. First of all, the standard defines various terms. For example, mobile power supply refers to the non fixed power supply system composed of battery or battery pack, corresponding circuit and shell, which can provide stable DC output, and not more than 18kg of power supply which is expected to be carried by users.
2、 Scope of application of the standard:
1. Mobile power supply refers to the non fixed power supply system composed of battery or battery pack, corresponding circuit and shell, which can provide stable DC output, and not more than 18kg of power supply that can be carried by users.
2. The input voltage of portable digital equipment shall not be greater than 250V, the output DC voltage shall not be greater than 60V, and the output current of single port shall not be greater than 5A. The mobile power supply with wired output mode shall be adopted. GB / T 35590 specifies the technical requirements, test methods, quality assessment procedures, marking, packaging, transportation and storage of mobile power supply for portable digital equipment. The main body of the standard includes: scope of application, normative references, terms and definitions, requirements, test methods, quality assessment procedures, signs, packaging, transportation and storage. The national standard of mobile power supply specifies the requirements, test methods, quality assessment procedures, marking, packaging, transportation and storage of mobile power supply for portable digital equipment. The specification is applicable to portable digital equipment with input voltage no more than 250V, output DC voltage no more than 60V, single port output current no more than 5a, and mobile power supply with wired output mode.
First of all, the standard defines various terms. For example, mobile power supply refers to the non fixed power supply system composed of battery or battery pack, corresponding circuit and shell, which can provide stable DC output, and not more than 18kg of power supply which is expected to be carried by users. Secondly, make specific and clear requirements for all aspects of mobile power, including: appearance identification, performance, safety protection, safety, electromagnetic compatibility, environmental adaptability, limit of limited substances, etc. For example, the cycle life of mobile power supply should not be less than 300 times, and the product must have over surge protection, over discharge protection, short circuit protection, overload protection, misoperation protection, etc. Mobile power supply involves 28 items of detection, such as appearance and identification, interface, effective output capacity, capacity retention capacity, cycle life, conversion efficiency, output voltage, ripple and noise, power adaptability under charging state, overcharge protection, over discharge protection, short circuit protection, overload protection, misoperation, electrical safety of the whole machine, battery and battery pack, material flame retardant, stress relief Limited power supply, high temperature charging and discharging, radio disturbance, immunity, constant damp heat, temperature cycle, vibration, collision, free fall, limited substance limit.
