As I have mentioned in other posts in EBR forums, it's critical that the full electrical system be safety certified to UL 2849 to reduce the risk of fire and explosion. Just having a battery pack to UL 2271 is not sufficient to address the safety of the full electrical system. Often times...

Thank you Dewey for your explanation. Advocating for the American National Standard Institute’s accredited United States safety standards should be clear as to why that would be in USA Citizens best interest. Otherwise why even have national consensus standards that take years to reach...

Dear Dewey, Have you studied the EN and UL standards? If not how would you know what’s actually addressing the product safety of an e-bike or its battery? Many of the fires from e-bikes around USA or globally are from EN compliant e-bikes. EN ebike and related standards are not as robust as...

If a company other than UL Solutions has legitimately product safety certified, the manufacturer can say “Certified by ___ to UL 2849” where the blank is the certification company’s name. If a company only tested to UL 2849 it would not demonstrate compliance to the safety standard. I caution...

More than half the requirements of most UL safety standards are about construction, design, engineering, and material principles, not just about testing. UL 2849 is not a testing standard, it’s a system safety standard and requires engineering evaluation to determine product compliance. An ISO...

Pedego does not show up as UL Certified at the links shared. If there are advertisements of UL Certified coming from any company who doesn’t show up on UL’s certification directory please report that at this link: https://market-surveillance.ul.com/

Shimano does not come up on UL’s certification listing database. Here are the existing Listee companies that have ULS Listed e-Bikes: https://productiq.ulprospector.com/en/search?term=qgns Here are the existing Listee companies that have ULS Listed e-Scooters & e-Mobility Devices...

Hi Tom, My apologies for the late reply. UL 2849 covers the electrical system of an e-bike and the integration of the various components to make the system. It evalautes and tests to the forseeable use and misuse of an ebike. Over 20 companies are voting members on its requirements coming...

Great list that you have started to build utilizing available sources! It would be ideal if the brand who says they are certified provide a web link back to the certification organization who has actually issued it for the electrical system that is being used on their e-bike. For example here...

UL Solutions Market Surveillance department investigate any concerns reported from consumers, regulators, and any other concerned party related to products identified as UL Certified. Market Surveillance actively monitors CPSC for recalls that involve UL Marked products. They open...

While the NYC law does not explicitly mention OSHA National Recognized Test Laboratories (NRTLs) with scope of recognition to UL 2849, UL 2272, and UL 2271, it does make a lot of sense these would be the approved certification organizations given the fact the US government has recognized some of...

Fire protection is multi-prong approach. FDNY has given great education that only use the lithium ion batteries designed for the end product. Full electronic, environmental, and mechanical protection for battery packs is defined in UL 2271. At this time most used batteries have not been...

Battery packs submitted for formal certification evaluation at the same time the ebike electrical system is submitted can be evaluated to UL 2271 and UL 2849 concurrently.

Sorry just seeing your post Ron. Please see my post here with the link to the database: https://electricbikereview.com/forums/threads/ul-certified-ebikes.44690/page-2#post-592355

Electric motor have been suspected as the starting incident that leads to lithium battery fire in some cases. In lab environments, non-compliances have occurred specific to motor requirements and tests when certifying to UL 2849. Other parts of the system have an affect whether or not the...

Safety never sleeps! I appreciate your questions and helping clarify things. A used intact UL-certified battery pack retains its certification so long as it not damaged, defective, or tampered with. It should be used in the intended end product it was designed for. Using an intact UL-certified...

For the battery packs certified to UL 2271, the UL Recognition Mark will be the most common mark and will have a file number printed underneath the logo beginning with “MH” and then 5 numbers. In my first post I shared links to the UL Database that can be used to confirm authenticity. However...

That is not true that only the battery pack is the significant fire concern. The electrical system of an e-bike inclusive of e-motor, safety circuits, battery charger as well as the battery packs pose fire, explosion, and/or electric shock risk. If there was not concern over the full electrical...

Hello, Thank you for your questions. I will try to answer them succinctly. 1. The ebike with an AW motor, is it UL 2849 Certified? If not, it would not meet the recently passed NYC micromobility law. Clause 20 of UL 2849 describes the Motor and Motor Control safety requirements. There are...
