UL2271 is a new standard for lithium batteries for electric vehicles (including balance cars and torsion cars)
Electric bicycle UL2271 certification event development background
recently, the balance car scooter has been controversial. The American Consumer Goods Association (CPSC) announced that all manufacturers, importers and distributors of balance cars (including twist cars) must meet new standards for balance cars produced, imported and sold in the United States, including the UL2272 balance car circuit system certification standard and the UL2271 balance car lithium battery new standard. In addition, all balance car batteries must meet the UN38.3 certification requirements.
UL's new regulations for balancing vehicle certification, UL2272 certification, UL2271 certification and standard formulation, our scientific and research engineering team have developed appropriate testing requirements and methods to confidently evaluate and test the mechanical structure, electrical and fire hazard systems of the entire balancing scooter. Today we are pleased to announce the availability of testing and certification services to manufacturers and distributors in the market.
Electric bicycle UL2271 certification documentation requirements:
1. Appearance size drawing (mainly marking the overall size)
2. Battery pack specification
3. Circuit diagram of protection board
4. PCB Layout of the protection board
5. BOM of protection board
6. Electronic label (including: UL LOGO, model, voltage, capacity (Ah or Wh),LithiumIon Battery or similar, production date, polarity logo, warning statement)
7. Coding rules for production dates.
8. FMEA Report
9. Product instructions
Electric bicycle UL2271 certification warning to be marked on the label:
a. Use Only (__) Charger
b. In English: Warning: Hazardous Voltage Circuits; and
In French: «Attention : Circuits à tension élevée»
c. In English: WARNING - To reduce the risk of injury, user must read instruction manual; and In French: «AVERTISSEMENT - Pour prévenir les blessures, l'utilisateurdoit lire le manuel d'utilisation»
Electric bicycle UL2271 certification meaning:
there will be a great risk if the supply of twisted cars in the US market and warehouses continues to be sold. For manufacturers, if your products want to export to the United States, it may not be your problem. And certification. Next, CPSC will increase its efforts to inspect companies or individuals that continue to produce, sell, and import failing twisted cars, including at ports, airports, and even pre-inspection of goods on the road (sea). UL2271 certification of the standard is for all balance car products, not a single finger twist. After the standard for the US market comes out, it is likely that more countries will adopt the standard.
