Mobile power supply, also known as power bank, is welcomed by consumers because of its light weight, small size, easy to carry, easy to charge mobile phones and other electronic products. However, the mobile power supply has the possibility of bringing certain safety risks to consumers because of its internal lithium-ion batteries and uneven quality on the market. The results of the 2022 national supervision and random inspection of mobile power released by the State Administration for Market Regulation show that about 25% of the mobile power products sampled are unqualified, and the problems found mainly include various safety hazards such as leakage and fire.
anke Jie for you to organize mobile power related international and major countries and regions of the safety standards, see below:
IEC International Standards
IEC 62133-2: 2017+A1: 2021 Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications -Part 2: Lithium systems
secondary cells and batteries containing alkaline or other non-acid electrolytes-Safety requirements for portable sealed secondary cells and batteries-Part 2: Lithium system
the role of mobile power supply is mainly to power electronic products, so it can also be considered as a rechargeable battery, suitable for IEC 62133-2 standard.
IEC 62368-1: 2018 Audio/video, information and communication technology equipment -Part 1: Safety requirements
audio, video, information technology and communication technology equipment-Part 1: Safety requirements
mobile power is mostly used to charge audio and video products such as mobile phones and computers, and is used in conjunction with audio and video products, so it is also suitable for IEC 62368-1.
North America
UL 2056 Outline of Investigation for Safety of Lithium-ion Power Banks
Lithium-ion Mobile Power Supply Safety Outline
UL/CSA 62368-1 Audio/video, information and communication technology equipment -Part 1: Safety requirements
Audio, video, information technology and communication technology equipment-Part 1: Safety requirements
The United States and Canada also issued with IEC 62368-1 in conjunction with the UL/CSA 62368-1 standard, but there are corresponding national deviations.
South Korea
KC 62133-2 Secondary cells and batteries containing alkaline or other non-acid electrolytes - Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications -Part 2: Lithium systems
secondary cells and batteries containing alkaline or other non-acid electrolytes-Safety requirements for portable sealed secondary cells and batteries-Part 2: Lithium system
south Korea mainly controls the battery in the mobile power supply, KC 62133-2 standard is also used to evaluate the safety of the mobile power supply, which is deviated from IEC 62133-2. For the test of the mobile power supply, the main deviation is that the voltage requirement used in the overcharge test is stricter.
Japan
METI Appendix 12 J62133-2: Safety of Rechargeable Batteries for Portable Devices - Part 2: Lithium Secondary Batteries
safety of rechargeable batteries in portable equipment-Part 2: Secondary lithium batteries
japan classifies mobile power supplies as portable lithium-ion batteries, which are suitable for the J 62133-2 standard in the Japanese PSE standard and need to meet the requirements of circular PSE.
China
GB/T 35590: 2017 Information technology - General specification for portable digital equipments used power bank
information technology-General specification for mobile power sources for portable digital devices
china has also promulgated the national standard GB/T 35590 for mobile power supply.
GB 4943.1:2022 Audio/video, information and communication technology equipment -Part 1: Safety requirements
audio, video, information technology and communication technology equipment-Part 1: Safety requirements
similarly, GB 4943.1 in conjunction with IEC 62368-1 is also suitable for mobile power supplies.
It should be noted that in September 2022, the State Council issued a notice that mobile power products will be included in the national compulsory certification management, and the quality management requirements for mobile power products will be more stringent in the future.
Transportation Safety (Global Requirements)
UN 38.3: Recommendations on the transport of dangerous goods-Manual of Tests and Criteria-Sub-section 38.3: Lithium metal and lithium ion batteries
UN Recommendations for the Transport of Dangerous Goods-Manual of Tests and Criteria-Chapter 38.3: Lithium Metal and Lithium Ion Batteries
mobile power supply is regarded as lithium ion battery in transportation safety requirements, and safety test shall be carried out according to UN 38.3, and test report and safety transportation appraisal report shall be obtained before transportation.
