Introduction This introduction is not part of IEEE Std 485-2010, IEEE Recommended Practice for Sizing Lead-Acid Batteries for Stationary Applications. The storage battery is of prim

3、ary importance for the satisfactory operation of generating stations, substations, and other stationary applications. This recommended practice is based on commonly accepted methods used to define the load and to ensure adequate battery capacity. The method described is applicable to all installatio

4、ns and battery sizes. The installations considered herein are designed for operation with a battery charger serving to maintain the battery in a charged condition as well as to supply the normal dc load. This recommended practice does not apply to “cycling” applications. (See IEEE P1660TM/D9, June 2

5、008 B2asubject to approval before this revision is approved.) This recommended practice was prepared by the Lead Acid Battery Sizing Working Group of the Stationary Battery Committee. It may be used separately, but when combined with IEEE Std 450TM-2002band IEEE Std 484TM-2002 (for vented lead acid

6、batteries) or IEEE Std 1187TM-2002 and IEEE Std 1188TM-2005 (for valve-regulated lead-acid VRLA batteries), it will provide the user with a general guide to designing, placing in service, and maintaining the applicable lead-acid battery installation.

41、eplacement of Valve-Regulated Lead-Acid (VRLA) Batteries for Stationary Applications. 3. Definitions For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dictionary: Glossary of Terms for example: The available capacity of the battery decreases as its temp

42、erature decreases. The available capacity decreases as the discharge rate increases. The minimum specified cell voltage at any time during the battery discharge cycle limits the available capacity of the battery. 6.1 Number of cells The maximum and minimum allowable system voltage determines the num

43、ber of cells in the battery. It has been common practice to use 12 cells, 24 cells, 60 cells, or 120 cells for nominal system voltages of 24 V, 48 V, 125 V, or 250 V, respectively. In some cases, it may be desirable to vary from this practice to match the battery to system voltage limitations more c

44、losely. It should be noted that the use of the widest possible voltage window, within the confines of individual load requirements, will result in the most economical battery. Furthermore, the use of the largest number of cells allows the lowest minimum cell voltage and, therefore, the smallest size

45、 cell for the duty cycle. The application of the following principles is illustrated in A.1 of Annex A. IEEE Std 485-2010 IEEE Recommended Practice for Sizing Lead-Acid Batteries for Stationary Applications 7 Copyright 2011 IEEE. All rights reserved. 6.1.1 Calculation of number of cells and minimum

46、cell voltage When the battery voltage is not allowed to exceed a given maximum system voltage, the number of cells will be limited by the cell voltage required for satisfactory charging or equalizing. This is as follows: cells ofnumber for required voltagecell voltagesystem maximum =Example: Assume

47、2.33 V/cell is required for equalize charging and that the maximum allowable system voltage is 140 V or 135 V. Then 140 V60.09 cells (use 60 cells)2.33=135 V57.94 cells (use 58 cells)2.33=If the number of cells is rounded off, the charging voltage should then be recalculated and verified for adequac

48、y of operation. The minimum battery voltage equals the minimum system voltage plus the cable voltage drop. Ensure all voltage drops are considered: For example, the use of unusually long cable connections within the battery or inter-cell connections resistances greater than the values on which the r

49、atings are based may require an adjustment to the calculated minimum battery voltage. The minimum battery voltage is then used to calculate the allowable minimum cell voltage. voltagecell minimumcells ofnumber ltagebattery vo minimum=In an application with a wide voltage window, particularly when long discharge times are required, the minimum cell voltage recommended by the manufacturer for a given discharge time may be a factor. If so, reduce the number of cells in the preceding calculation so that the minimum cell voltage per cell does not fall below the
