It was recently learned that Amazon asked mobile power sellers to provide UL 2056 certification. If they did not provide UL certification before May 25, all mobile power will be banned. The ban was imposed on Amazon's official platform, targeting all types of mobile power. UL 2056 is a special detection standard for mobile power supply. What are the requirements of this standard for mobile power supply and how to obtain UL 2056 certification? Let's learn about it.
UL 2056 Scope of Application
UL 2056 is the world's first standard for mobile power supply. It aims to protect consumers from personal and property damage caused by dangerous accidents such as fire and explosion of mobile power supply, while helping manufacturers reduce the risk of expensive product recovery and brand damage.
UL 2056 certification-1
UL 2056 is a standard for mobile power supply with a maximum DC input voltage of 60V or a direct-plug AC power input and a maximum DC output of 60V for low-voltage electronic products. Batteries with built-in solar panels are also applicable. However, it is not applicable to use special external solar panel power supply or mobile power supply powered by vehicle 12V charger.
Requirements for Components of Mobile Power Supply
The battery, housing, fuse and other components of the mobile power supply need to meet the requirements of the following standards:
UL 2056 certification-2
Requirements for Mobile Power Supply
1. Structure:
1.1 The whole mobile power supply meets the requirements of UL 2054, mainly refers to the housing, external connectors and PCB board.
1.2 If there is 42.4Vac or 60Vdc voltage generated by built-in DC/DC conversion line, the line requirements meet UL 60950-1 or UL 62368-1.
1.3 For direct plug-in mobile power supply: the mobile power supply should meet the requirements of UL 60950-1 or UL 62368-1, and isolate between the built-in battery pack and the built-in ac/dc power supply.
1.4 The lithium cores in the mobile power supply must meet the requirements of UL 1642.
2, performance
2.1 The performance of mobile power supply should meet the requirements of UL 2054, but considering some differences in PCB design between battery and mobile power supply, there will be some special requirements in some tests, such as: DC/DC conversion lines need to be shortened in abuse test; when charging temperature rise test, batteries need to be under the maximum load condition (all loads are running at the same time).
3. Energy Input Test
3.1 The input current of the mobile power supply does not exceed 110% of the rated current when all the loads are running, including the built-in batteries being charged.
4. Load Testing of Output
4.1 Each output need to be tested.
4.2 The maximum output current of the output terminal is used for 1 h.
5. Combustion Testing of Photovoltaic Cells
5.1 This requirement applies to mobile power supply with built-in photovoltaic panels.
5.2 The test requires a single fault mobile power supply, in order to make the photovoltaic cells possible to burn before testing.
How to obtain UL 2056 certificate?
Products in North America can be sold with certificates issued by NRTL-accredited laboratories. NRTL is a product safety testing certification service approved by the Occupational Safety and Health Administration (OSHA) under the Federal Code of 29 CFR 1910.7. OSHA is the NRTL's accreditation organization and manager. The first NRTL was born in 1989. At present, there are 16. Dephwa Testing can act as an agent for UL 2056 certification of mobile power supply to help customers obtain certificates and eliminate trade barriers.
