The UL2272 certification standard for electric scooters was officially announced in February 2016. The American Consumer Product Safety Association (CPSC) announced that all manufacturers, importers, and distributors of balance vehicles (including torsion vehicles) produced, imported, and sold in the United States The balance car must meet the latest safety standards, including the UL2272 circuit system certification standard for electric scooters. In addition, all balance car batteries must comply with un38.3 certification requirements.
used to go to Amazon in the United States, and they could go directly. UL report is required for spot checks only after being put on shelves, and UL report is required for Listing if UL certification cannot be provided. At present, many products will be required to provide UL certification when they are directly on the shelves.
UL2272 certification range ofelectric scooter:
Light Vehicle (LEV)-A light vehicle that uses electricity as a power source.
1) electric bicycle;
2) Electric scooter;
3) Electric wheelchair;
4) golf carts;
5) all-terrain vehicle;
6) Non-cycling industrial material handling equipment;
7) Riding floor care machines and lawn mowers;
8) Personal Mobile Devices
This requirement covers an electric drive self-balancing vehicle system consisting of an electric drive powertrain, a battery, and a battery charging system.
the structural requirements of the UL2272 certification ofelectric scooter:
1, non-metallic materials
theshell material has a fire rating above V-1.
plastic RTI temperature rating is greater than 80°C.
plastic enclosures used in outdoor conditions must meet the requirements of UL746C for UV resistance, waterproofing and immersion.
the durability of safety-related waterproof strips and sealing materials needs to be considered according to the environment in which they are used and the chemicals they may come into contact. Meet the test and evaluation of the strip in the UL 157.
2, Corrosion Resistance Requirements for Metallic Materials
metallic materials require a suitable coating to prevent corrosion that may occur in service, refer to UL 50E.
If an insulating liner is required inside the metal housing to prevent the housing from causing short circuits to the internal current lines, the liner must be made of a non-hygroscopic material and its temperature performance must meet the relevant operating environment requirements including charging.
3, Shell Design
enclosures are designed to meet IP34, reference standard IEC 60529.
4, Wiring and Terminal Requirements
If the battery pack is designed to be taken out of the balance car when charging, the external terminal design of the battery pack needs to meet the durability requirements in UL2251 under no-load and full-load conditions.
5, Charger Requirements
chargers need to meet UL1310, UL1012 or UL60950-1.
6, Fuse Requirements
The fuse shall conform to UL248, and the rated parameters shall conform to the actual conditions of use.
