UL 2849:2020 PDF Download

The UL 2849:2020 standard provides guidelines and requirements for the electrical systems of eBikes powered by lithium-based, rechargeable batteries. This standard covers both Electrically Power Assisted Cycles (EPAC) with pedal assist and non-pedal assist eBikes.

The electrical systems addressed in this standard include both onboard and off-board components of eBikes. The minimum required electrical system components comprise the drive unit, battery, battery management system (BMS), interconnecting wiring, and power inlet. Depending on the specific application and risk factors, additional components or systems necessary for compliance may also be included.

Off-board components referenced in the standard encompass dedicated chargers for charging batteries that are either removed from the eBike during charging or left in place on the eBike during the charging process.

It's important to note that this standard does not cover the mechanical structure of the eBike unless explicitly stated otherwise. The focus is primarily on the electrical aspects of the system to ensure safety and compliance with standards.
