Scope:

These requirements cover portable and movable power packs provided with one or more batteries, electrochemical capacitors, or electrochemical capacitor modules. If provided with a battery, the battery shall be either a lead acid or lithium ion battery. The power packs are provided with one or more inputs and one or more outputs. For power packs provided with a booster function, the power packs are used for providing a temporary power source to a depleted land vehicle battery, rated 24 V dc maximum, to provide emergency starting power.

These requirements cover power packs suitable for outdoor use, temporary outdoor use, or indoor use only. Outdoor use packs are intended to be used outdoors with no restrictions. Temporary outdoor use packs are intended to be used outdoors in limited wet conditions and always stored indoors. Indoor use only packs are intended to be stored indoors and used indoors and are not intended to be used outdoors at any time. A power pack with a booster function is not considered indoor use only under any conditions.

 

These requirements cover power packs provided with additional systems such as an air compressor (tankless type) for inflating tires or other inflatable items, or with a light to act as warning lights to oncoming traffic, as a flashlight, or the like. These functions are also powered by the internal battery.

These requirements cover the power pack options such as lights, voltmeters, internal air compressor assemblies, associated gauges, inverters, vehicle adapters, and internal batteries, as well as the charging of the internal batteries, when these options are integral to the power pack.

Project need:

The following changes to ANSI/CAN/UL 2743 are being proposed: 1. Clarification to definition of hazardous voltage level 2. Addition of definition of "portable or moveable" 3. Alignment of requirements for sub-enclosures with UL 746C 4. Receptacle output not supplied by AC mains 5. Increase the vehicle adapter voltage rating 6. Replacement of UL 60950-1 with UL 62368-1 for external charger standard 7. Double insulated products with functional earthing 8. Alternative cell standard for Lithium and Lead Acid batteries 9. Addition of alternative standard for inverters in the power pack 10. Addition of mass limitation for stability test 11. Addition of the induction output and energy hazard measurement test 12. Addition of LVLE circuit requirements and test 13. Clarification of Leakage Current Test with hazardous voltage circuits 14. Option of single fault condition in control circuit besides functional safety evaluation 15. Clarification of the short circuit resistance for output short circuit test 16. Charging current for Overcharging Test 17. Additional requirements for large energy storage systems (ESS) 18. Strain relief test for interconnecting cable 19. Updates to the Impact Test and Drop Test 20. Clarification of the compliance criteria for the Rain Test 21. Power Pack Ampacity Test and booster ampacity rating marking 22. Addition of UL 969A requirements for flag labels 23. Revisions to Markings and Instructions 24. Addition of instruction for booster cable connection and disconnection to battery 25. Clarification to Annex A as Normative or Informative
