1 Scope
1.1 This Standard covers the electrical system of eBikes powered by a lithium-based, rechargeable battery. EBikes include both Electrically Power Assisted Cycle (EPAC – pedal assist) and non-pedal assist eBikes.
1.2 Electrical systems as referenced in 1.1, may include onboard components and off board components of eBikes. As a minimum, the electrical system consists of the drive unit, battery, battery management system (BMS), interconnecting wiring, and power inlet. Any additional components or systems required to demonstrate compliance are included based on the overall system application and risk.
1.3 Off board components include dedicated chargers for charging batteries that are removed from the eBike during charging or dedicated chargers for charging batteries that are in place on the eBike during charging.
1.4 This Standard does not cover the mechanical structure of the eBike unless specified otherwise.

Project Need
Various revisions are proposed for ANSI/CAN/UL 2849 including:
1. Rephrase the applicability of Section 12 to BMS
2. Add reference to alternate battery charger standards
3. Clarify the vibration axis required for the complete device when conducting the vibration test
4. Align pedal cessation test with EN 15194
5. Clarify strain relief test also applies to hazardous energy circuit
6. Clarify the determination of a hazardous energy level
7. Add references to alternate standards for positive temperature coefficient device
8. Revise requirements to address wireless battery-charger systems and components
9. Align dielectric strength test condition
10. Add tolerance of speed for startup assistance mode test and cutoff at maximum speed test
11. Clarify marking requirements
12. Add motor windings Tmax value when measuring temperature with resistance method
13. Update compliance criteria of impact test and mold stress test
14. Add endurance test for the external terminal of a removable battery pack
15. Add references to additional standards for cables and connectors
16. Add exceptions to enclosure requirements in accordance with UL 62368-1/CAN/CSA C22.2 No. 62368-1
17. Revise short circuit test to specify discharge protection/control circuit
18. Revise enclosure requirements in accordance with UL 746C
19. Revise gasket requirements to specify UL 157
20. Revise flammability requirements to incorporate requirements of UL 62368-1/CSA C22.2 No. 62368-1
21. Revise operator interface requirements to address communication devices
22. Revise shock and vibration test requirements to allow testing to CSA C22.2 No. 62133-2/UL 62133-2
23. Clarification of functional safety requirements
