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.
