JULY 3, 2018 PORTABLE POWER PACKS - UL 2743 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements

42、 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 m

43、ore 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. 1.2 These requirements cover power packs suitable for outdoor use, temporary

44、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

45、 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. 1.3 These requirements cover power packs provided with additional systems such as an air compressor (tankless type) for inating tires or other inatable items, o

46、r with a light to act as warning lights to oncoming traffic, as a ashlight, or the like. These functions are also powered by the internal battery. 1.4 These requirements cover the power pack options such as lights, voltmeters, internal air compressor assemblies, associated gauges, inverters, vehicle

47、 adapters, and internal batteries, as well as the charging of the internal batteries, when these options are integral to the power pack. 1.5 These requirements do not cover wiring or cabling used in the recharging function of electric vehicle recharging equipment. 1.6 These requirements do not cover

48、 power banks which are covered in the Outline of Investigation for Power Banks, UL 2056. 2 Units of Measurement 2.1 The values given in SI (metric) units shall be normative. Any other values are for information only. 2.2 Values stated without parentheses are the requirement. Values within parenthese

49、s are considered explanatory or approximate information.
