27、ed with one or more batteries 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 as shown in 1.2; and they are provided with one or more outputs as shown in 1.3. For po
28、wer 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 maximum, to provide emergency starting power. 1.2 Power packs shall be provided with one or more of the input options as shown below: a) Cord and
29、 plug connection, rated at 240 V ac maximum, to and/or 60 Hz; b) Photovoltaic panel or device with inverter; c) Vehicle adapter, rated 12 V dc maximum; or d) USB input port (can also act as output port). 1.3 Power packs covered by this outline shall be provided with one or more of the following outp
30、uts, with the exception that one of the outputs in items (a) (c) are provided as a minimum: a) Booster cables to provide a temporary power source to a depleted land vehicle battery, rated 24 V maximum, to provide emergency starting power or recharging of the external vehicle battery; b) One or more
31、receptacles, each rated no more than 125 V ac, 15 A; c) DC output connectors rated 24 V dc maximum; or d) Standard USB port outputs. 1.4 Power packs may be considered suitable for outdoor use, suitable for temporary outdoor use, or suitable for indoor use only. Outdoor use packs can be used outdoors
32、 with no restrictions. Temporary outdoor use packs may be used outdoors but should be used carefully in wet conditions and always stored indoors. Indoor use only packs must be stored indoors and used indoors and cannot be used outdoors at any time. A power pack with a booster function shall not be c
33、onsidered indoor use only under any conditions. 1.5 With reference to 1.3, power packs may also be provided with additional systems such as an air compressor (tankless type) for inating tires or other inatable items, or with a light to act as warning lights to oncoming traffic, as a ashlight, or the
34、 like. These functions are also powered by the internal battery. 1.6 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 batteri
35、es, when these options are integral to the power pack. OCTOBER 14, 2016 PORTABLE POWER PACKS - UL 2743 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 1.7 These requirements do not cover wiring or cabling used in the recharging function of
36、electric vehicle recharging equipment. 2 Units of Measurement 2.1 Values stated without parentheses are the requirement. Values within parentheses are considered explanatory or approximate information. 3 Components 3.1 Except as indicated in 3.2, a component of a product covered by this outline shal
37、l comply with the requirements for that component. 3.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this outline, or b) Is superseded by a requirement in this o
38、utline. 3.3 A component shall be used in accordance with its ratings established for the intended conditions of use. 3.4 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as ce
39、rtain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 4 Undated References 4.1 Any undated reference to a code or standard appearing in the requirements of this outline shall be interpreted as referring to the latest edition of that code or standard.
40、5 Glossary 5.1 For the purpose of this document, the following denitions apply: 5.2 ACCESSIBLE Able to be contacted by an accessibility probe. 5.3 BATTERY An electrical storage unit consisting of two or more cells. 5.4 BOOSTER CABLE The conductors that originate at the power packs internal battery a
41、nd terminate at the clamps that are intended to be temporarily connected to the land vehicles battery. If the cable is connected through a switch and therefore does not have a continuous path to the exterior of the power packs enclosure, then the denition shall apply to the portion of cable that exi
42、ts the power packs enclosure. 5.5 BOOSTER FUNCTION When the power packs are used for providing a temporary power source to a depleted land vehicle battery, rated 24 V maximum, to provide emergency starting power. 5.6 CAPACITOR MODULE A single or multiple series and/or parallel-connected, electrochem
43、ical capacitors with associated circuitry. OCTOBER 14, 2016 PORTABLE POWER PACKS - UL 2743 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 5.7 CHARGING SYSTEM Combination of circuitry intended to charge, balance, and/or maintain the state o
44、f charge of the battery. 5.8 CLAMP Devices located at the ends of the power packs booster cables, and which contain the jaw ends, connectors, and handle ends, which are used to make the temporary connections to the land vehicles battery. 5.9 CLAMP: CONNECTORS Portion of the clamp that contacts the b
45、attery terminals. 5.10 CLASS 2 POWER SUPPLY A source having limited voltage and energy capacity. Requirements for voltage and energy capacity limitations are as indicated in this document. 5.11 CLEARANCE Shortest distance between two conductive parts, or between conductive parts and the conductive d
46、ead metal parts of the enclosure, measured through air. 5.12 CONDUCTORS Wiring used internally and externally on the power pack. 5.13 CREEPAGE DISTANCE Shortest distance between two conductive parts, or between conductive parts and the conductive dead metal parts of the enclosure, measured along the
47、 surface of insulating material. 5.14 ELECTROCHEMICAL CAPACITOR An electric energy storage device where electrical charge is stored as a result of non-Faradaic processes at one or both of the electrodes. (A subset of electrochemical capacitors referred to as an “asymmetric electrochemical capacitor”
48、 have non-Faradaic processes at one electrode and Faradaic processes at the other electrode.) The unique highly-porous electrode increases its surface area for holding charge resulting in much larger capacitance and energy density than other types of capacitors. Electrochemical capacitors differ fro
49、m common electrolytic capacitors in that they store charge at the liquid-solid interface of the electrodes when a potential is applied rather than in a solid dielectric material covering the surfaces of the electrodes. Some other common names for an electrochemical capacitor are “double layer capacitor”, “ultra-capacitor”, “electrochemical double layer capacitor”, “super-capacitor”, and EDLC. 5.15 ENCLOSURE That part of the product that: a) Renders inaccessible all or any parts of the equipment t
