　　National standards and technical specifications for portable UPS emergency starting power supplies. As there are more and more portable UPS emergency power supply manufacturers, the quality of their products is uneven, and some are even substandard, leading to chaos in the UPS market. Users need to spend a lot of time to refer to and compare different portable UPS power supply manufacturers. In response to this situation, the country has introduced a series of policies and technical specifications to standardize the portable UPS market. The editor introduces some technical specifications in detail in this article, and then read on.

　　What is a portable UPS emergency power supply?

　　Portable UPS emergency power supply is a safe, portable, stable and environmentally friendly small energy storage system. It can provide you with very portable and sustainable green energy solutions. Portable UPS is widely used in various fields, such as outdoor office, outdoor photography, outdoor construction, backup power supply, emergency power supply, fire rescue, disaster relief, car starting, digital charging and mobile power supply.

　　National standards and technical specifications for portable UPS emergency starting power supplies

　　National standard GB31241-2014 for portable UPS emergency starting power supplies. This standard mainly specifies the requirements for electrical safety, environmental safety, and mechanical safety under normal use, reasonably foreseeable misuse and abuse conditions for lithium battery cells and lithium battery packs. Test Methods.

　　According to the test indicators, in addition to the conventional general safety requirements (safe working parameters, labeling requirements, warning instructions, durability), the test items of portable UPS lithium battery packs also include battery pack environmental tests, battery pack electrical safety tests, battery pack There are more than 30 tests including protection circuit safety test requirements and system protection circuit safety requirements.

　　The standard fully refers to the mature test methods in relevant international and foreign advanced standards (UN, IEC, UL, etc.), and has revised and improved the thermal abuse test, overcharge test, drop and other test methods, and newly added protection circuit test, New test requirements such as high-temperature use tests and material flame retardant requirements, among which standard innovations such as thermal abuse tests and protection circuit tests have been adopted by relevant international standards.

　　The technical specifications of the portable UPS emergency starting power supply are formulated based entirely on the basic principles of standardization, namely the unification principle, the simplification principle, the coordination principle and the optimization principle.

　　The technical specifications of portable UPS emergency starting power supply mainly include: scope of application, technical conditions, test methods, factory inspection requirements, and requirements for marking, packaging, and transportation.

　　1. Scope of application: This technical specification puts forward certain requirements for the related applications of lithium-ion electromagnetism for energy storage systems.

　　2. The content in this technical specification is based on the test data of representative enterprises. The safety and convenience mainly refer to the relevant requirements of UL1642 and UL2054. The performance and other aspects mainly refer to the requirements of the communication industry and lithium batteries for electric vehicles. The main reference standards are: QC/T743-2006, YD/T2344.1-2011, JB/T11137-2011, etc.

　　3. In addition, considering the special environmental requirements of lithium batteries used in energy storage systems, experimental items such as resistance to low voltage, hot and cold shock, and damp heat have been added to ensure that the needs of the actual application environment can be concealed.

　　Nowadays, there are corresponding national standards for portable UPS emergency starting power supplies. The editor hereby reminds everyone that when purchasing, you must make sure that the main products comply with national safety standards and purchase with caution.
