Energy storage power supply UL2743 certification test in the United States

What is UL2743 certification? What products require UL2743 certification?

1. The UL2743 standard covers portable and portable power sources equipped with one or more batteries, electrochemical capacitors, or electrochemical capacitor modules. If equipped with batteries, they should be lead-acid or lithium-ion batteries. The power pack has one or more inputs and one or more outputs. For power packs with boost function.

2. The UL2743 standard covers large portable power banks for outdoor, temporary outdoor, or indoor use. The outdoor use bag is designed for unrestricted outdoor use. The temporary outdoor use bag is intended to be used outdoors under limited humid conditions and always stored indoors. The packaging bag intended for indoor use only is intended for storage and use indoors, and is not intended for outdoor use at any time. Under no circumstances should a power box with boost function be considered for indoor use.

3. The UL2743 standard covers powertrains equipped with additional systems, such as air compressors (non tank type) for inflating tires or other inflatable items, or lights, flashlights, etc. that serve as warning lights for imminent traffic. These functions are also powered by internal batteries.

4. The UL2743 standard covers power pack options such as lights, voltmeters, internal air compressor components, related instruments, inverters, vehicle adapters, and internal batteries, as well as charging the internal battery when these options are integrated with the power pack.

5. The UL2743 standard does not include wiring or cables for the charging function of electric vehicle charging equipment.

6. The UL2743 standard does not include mobile power banks covered by the UL2056 Mobile Power Bank Investigation Outline.

The UL2743 certification standard mainly includes the following requirements:

1. Performance requirements: The energy storage emergency power supply needs to start immediately after power failure and provide power to critical loads, such as hospitals, banks, gas stations, and other emergency equipment that must remain operational.

2. Battery requirements: The battery must have sufficient energy density to provide sufficient electrical energy and have good charging and discharging efficiency.

3. Safety requirements: The energy storage emergency power supply must have functions such as overvoltage protection, overcurrent protection, short circuit protection, over temperature protection, fire protection, etc.

4. Capacity and Durability Testing: The capacity and durability testing of energy storage emergency power sources needs to be conducted in accordance with standard requirements to ensure that they can provide long-term stable backup power (Shunj93).
