On July 15, 2022, the National Bicycle Dealers Association (The National Bicycle Dealers Association, hereinafter referred to as "NBDA") issued a statement recommending that all retailers request suppliers to supply electric bicycles or installed on electric bicycles. The electrical system must be certified based on UL 2849.
NBDA will continue to guide retailers and the industry as a whole, as consumer demand for electric bicycles and scooters that use lithium-ion batteries as a source of power for electric propulsion systems increases, and safety concerns are growing.
NBDA President Heather Mason (Heather Mason) said:
the bicycle industry needs to act now. After extensive consultations with experts in the field, the safety of lithium-ion batteries for e-bikes and e-scooters is an important and urgent topic that we need to take immediate action now. Our statement of advice for retailers takes into account the continued growth within the e-bike industry and the safety of all. If we do not address the core issues, we may see this trend develop to a point beyond our control.
About the Electric Bicycle UL 2849 Standard
electric bicycles enter the U.S. market, there are relatively strict market access threshold. The introduction and implementation of UL 2849 standards have ensured the quality of electric bicycle products and helped the industry develop healthier and longer.
UL Standards & Engagement released the first version of the OUTLINE UL 2849 safety standard for electric bicycle products in 2013, and has undergone several revisions to adapt the standard to changing product requirements. In 2018, the revision of the ANSI/CAN/UL 2849 standard was officially launched. After two years of discussion and revision, the ANSI/CAN/UL 2849 (the dual national standard of the United States and Canada) was officially released by UL on January 2, 2020. The purpose of the standard is to evaluate the electrical, mechanical, environmental and functional safety requirements of electric bicycle vehicles and their electrical systems, so as to ensure the safe use of products.
electric-driven bicycles (the driving electric energy comes from the on-board lithium battery, and only the driving mode of the electric motor output power), electric-assisted bicycles (the driving mode composed of manpower and the power of the electric motor in proportion to the output), and integrated electric drive and electric The electrical system of the bicycle with the auxiliary function.
electric bicycle electrical system related to thermal design, fire, electric shock, high current energy hazards and other potential hazards.
it involves the electrical safety, battery management system (BMS) and functional safety (including software evaluation) evaluation requirements of the product, and also has safety standard requirements for components such as battery pack, motor and charger.
