22/08/2023 At Alexander Battery Technologies, the safety of our battery packs is a top priority when we begin prototyping. When designing a battery pack for light electric vehicles (LEVs), we ensure our battery packs are designed and manufactured to UL2271 standard. A UL2271 certification is important for your battery pack as it is required for your product to meet regulations in some regions.
What is UL2271 Certification?
UL2271 certification was released in 2016 by Underwriters Laboratories, a global safety science organization. This standard covers the safety requirements for the design, manufacture, and testing of lithium-ion batteries used in LEV applications. It is now a necessity for all lithium-ion battery packs traded in the US to meet UL2271 certification. With other countries expected to follow suit, we ensure all our LEV application batteries meet UL2271 standard.
How is the battery pack tested?
Prior to achieving certification according to UL2271 standard, every battery must undergo a sequence of assessments.
The tests mandated by UL2271 standard encompass:
- Thermal runaway test
- Overcharge test
- Over-discharge test
- Crush test
- External short-circuit test
- Impact test
- Water immersion test
- Thermal cycling test
- Vibration test
- Forced discharge test
Examples of applications that require UL2271 certification
- E-Bikes
- E-Motorbikes
- E-Scooters
- Golf carts
- Hydrofoils
What does all of this do for your battery?
UL2271 certification ensures the battery is safe for the consumer and the product. This guarantee of safety is needed for the battery pack to be eligible for trade in the United States of America. UL2271 certification ensures an application’s power source will be durable and safe throughout the application’s lifetime.
To receive UL2271 certification, battery packs must not:
- Explode
- Catch fire
- Rupture
- Leak electrolytes
- present an electric shock hazard
- lose protection controls during testing
What does UL2271 mean for Alexander Battery Technologies?
We know if an OEM is looking for their battery pack to be UL2271 certified, the safety of their battery pack will be a top priority. Using our 40 years of battery pack manufacturing expertise we can design and manufacture a battery pack that can be UL2271 certified. Our battery packs are designed with our customers requirements at the forefront, allowing our engineers to prototype all aspects of the battery pack to pass the certification test. From the fittings to the casings, our battery packs are custom-made to fit your application.
Conclusion
Since its inception in 2016, the benchmark set for the safety of a battery pack used in LEV has been UL2271 standard. Using our wide range of industry knowledge, we know how a battery to design and manufactured to achieve UL2271 certification.
