With the increasing use of batteries and electrical systems, it is urgent to solve the safety problems they bring. The battery is the power core of personal light electric riding products. The latest UL standards cover the safety requirements for batteries and overall electrical systems, such as fire protection, explosion prevention, and electric shock prevention. More importantly, these standards will help our society to use battery technology widely in personal transportation in a safe and recognized way in the future.
electric bicycle-UL2849
UL 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, and to escort the safe use of products.
Batteries for Light Electric Vehicles-UL 2271
the second edition of theANSI/CAN/UL/ULC 2271 was released on September 7, 2018 to evaluate batteries for light-duty electric vehicles. The U.S. Occupational Safety and Health Administration (OSHA) issued a notice on January 18, 2019 requiring battery manufacturers to meet the corresponding safety standards. Among them, the applicable standard for light electric vehicle batteries is UL 2271. UL remains committed to working with industry manufacturers to improve product safety.
Battery Cell Requirements for Safety Standard for Power Batteries for Vehicles UL 2580
the third edition of theANSI/CAN/UL/ULC 2580 was released on March 11, 2020. UL 2580 covers the requirements for power cells and systems and is a dual national standard in the United States and Canada. Unlike regular battery standards, the UL 2580 standard not only covers strict testing requirements, but also has comprehensive requirements for battery structure, functional safety, labeling and instructions. For the requirements of the battery core part, the standard adopts double Appendix requirements (Appendix B and Appendix D), that is, meeting any Appendix requirements can be regarded as meeting the requirements of the standard. In terms of testing, the battery core involves capacity verification testing, mechanical testing and evaluation such as vibration, impact, impact, drop, extrusion, electrical testing and evaluation such as external short circuit, forced discharge, overcharge, and environmental testing and evaluation such as high temperature impact, temperature cycle, low air pressure, combustion and ejection. All-round consideration of the safety risks when the battery is used for power drive.
