21、PRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 1 Scope 1.1 These requirements address the safety of battery systems employing lithium ion cells that are intended for use in battery operated electric power tool and motor operated, heating and lighting appliance evaluations. The requirements co

22、ver both integral and detachable batteries but do not cover batteries or cells for general purpose use. 1.2 These requirements address the risk of re or explosion of these batteries and not any possible hazards associated with toxicity or electric shock nor potential hazards associated with transpor

23、tation or disposal. 1.3 Battery systems covered by these requirements are not intended to be serviced by the end user. 1.4 These requirements are structured so as to be used in conjunction with an end-product standard. These requirements are not intended to provide comprehensive evaluation of a batt

24、ery independent of an end-product standard. 1.5 These requirements address the safety of lithium ion battery systems during storage and use including discharge and charge. These requirements are only considered to be supplementary requirements in regards to battery charger re and electric shock. The

25、 safety of battery chargers for appliances are covered by other standards such as the Standard for Power Units Other Than Class 2, UL 1012, or the Standard for Class 2 Power Units, UL 1310. 1.6 These requirements refer to and require parameters supplied in reference to the cells that establish condi

26、tions for safe use of those cells. Those parameters form the basis of acceptance criteria for a number of tests contained herein. This standard does not independently cover the safety of cells. These parameters, taken as a set, constitute the Specied Operating Region for a cell. There may be several

27、 sets of specied operating region(s). 1.7 These requirements do not consider the effect of special applications (such as medical appliances) or special environments (such as hazardous locations). 1.8 These requirements have not assessed for the purposes of evaluating other end-product categories suc

28、h as information technology equipment, telecommunications, laboratory equipment, re alarm, security systems, emergency lighting, and audio-video apparatus, and may be incomplete with respect to those categories. 1.9 These requirements make frequent reference to the conditions and tests of the end-pr

29、oduct standard while often also providing minimum conditions or severity of tests. These minimum conditions shall not be construed to imply equivalence to end-product requirements. Conditions or requirements of end-product standards shall prevail over the conditions or requirements of this standard,

Values in parentheses are explanatory or approximate information. 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the req

32、uirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 3 Terms and Denitions 3.1 APPLIANCE A product, which is not a component of another product, whose primary output consists of heat, light, mechanical motion, or the movement of air. Within the

33、se requirements, appliance is assumed to refer to an appliance that derives its operating power from a battery. Appliances do not include products or vehicles intended for the transport of people or cargo. 3.2 BATTERY An assembly of one or more interconnected cells intended to provide electrical cur

34、rent to the appliance. For the purpose of these requirement this designation is limited to those batteries incorporating lithium ion secondary (rechargeable) cells. 3.2.1 DETACHABLE BATTERY PACK A battery which is contained in a separate enclosure from the appliance and is intended to be removed fro

35、m the appliance for charging purposes. The battery pack may contain additional circuitry. 3.2.2 INTEGRAL BATTERY A battery which is contained within the appliance and is not removed from the appliance for charging purposes. A battery that is to be removed from the appliance for disposal or recycling

36、 purposes only is considered to be an integral battery. 3.2.3 SEPARABLE BATTERY PACK A battery which is contained in a separate enclosure from the appliance and is connected to the appliance by a cord. For the purpose of these requirements, integral or detachable requirements would apply based upon

37、how charging is achieved. 3.3 BATTERY SYSTEM A combination of the battery, the charging system and the end product along with the interfaces between them as would exist in use. 3.4 C 5 RATE The current, in amperes, that a cell or battery can be discharged at for5ht ot h e voltage cutoff point specie

38、d by the cell manufacturer. FEBRUARY 25, 2011 UL 2575 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 3.5 CELL Basic functional electrochemical unit containing an assembly of electrodes, electrolyte, container, terminals, and usually separa

39、tors, that is a source of electrical energy by direct conversion of chemical energy. For the purposes of these requirements these cells are further understood to employ a lithium ion based electrochemistry. 3.6 CHARGING SYSTEM Combination of circuitry intended to charge, balance, and/or maintain the

40、 state of charge of the battery. 3.6.1 CHARGER Part or all of the charging system contained in a separate enclosure. As a minimum, the charger would include at least some of the power conversion circuitry. Not all charging systems require a charger as in the case where an appliance may be charged ut

41、ilizing a mains supply cord or may incorporate a plug for attachment to a mains receptacle. 3.7 EXPLOSION Failure that occurs when an appliance enclosure or a detachable or separable battery pack opens violently and major components are forcibly expelled in a manner that could result in injury. 3.8

42、FIRE The emission of ames from a battery. 3.9 FULLY CHARGED A cell or battery charged to achieve the maximum state of charge permitted by the battery charging system intended for use with the appliance. 3.10 FULLY DISCHARGED BATTERY (OR CELL) A battery or cell that has been discharged to the end of

43、discharge voltage at a rate of C 5 A until one of the following conditions occur: Discharge terminates due to protective circuitry or the battery (or cell) reaches a total voltage with an average equal to 2.5 V per cell, unless a different end of discharge voltage is specied by the manufacturer, whi

45、y may be different than the manufacturer of the product. A 12-V automotive battery and AA, C, and D alkaline cells are examples of general purpose. 3.12 SPECIFIED OPERATING REGION Range of permissible operation, expressed by cell parameter limits. 3.12.1 SPECIFIED OPERATING REGION FOR CHARGING Condi

46、tions during charging in which the cell operates within its voltage and current range as specied by the cell manufacturer and tested in accordance with the Standard for Lithium Batteries, UL 1642. In general, the permissible ranges of voltage and current are dependant upon temperature (see Figure 3.
