22、 This part of IEC 60896 is applicable to lead-acid cells and batteries which are designed for service in fixed locations (i.e. not habitually to be moved from place to place) and which are permanently connected to the load and to the d.c. power supply. Batteries operating in such applications are ca
23、lled “stationary batteries”. Any type or construction of lead-acid battery may be used for stationary battery applications. This part 11 of the standard is applicable to vented types only. The object of this standard is to specify general requirements and the main characteristics, together with corr
24、esponding test methods associated with all types and construction modes of lead-acid stationary batteries, excluding valve-regulated types. Recommendations on the use of tests for stationary battery application are given in Table A.1. Recommendations relating the type of cell or monobloc to the use
25、of tests are given in Table A.2. Statements and claims of basic performance data by the manufacturer shall correspond to those tests. The tests may also be used for type qualification. 2 Normative references The following referenced documents are indispensable for the application of this document. F

28、o-digital converters Page4 EN6089611:20033 Definitions For the purposes of the present part of IEC 60896, the following definitions apply. 3.1 electrolyte reserve volume of electrolyte between minimum and maximum level indication 3.2 rated capacity C rt quantity of electricity, declared by the manuf
29、acturer, which a cell or battery can deliver under specified conditions after a full charge. This value is usually expressed in ampere-hours (see IEV 486-03-22) 3.3 nominal capacity C nom suitable approximate quantity of electricity used to identify the capacity of a cell or battery. This value is u
30、sually expressed in ampere-hours (see IEV 486-03-21) 3.4 endurance ability of a cell or battery to function and withstand operations under specified conditions for a minimum period of time or repeated application thereof 4 Mechanical strength Stationary cells or batteries shall be designed to withst
31、and mechanical stresses during normal transportation and handling. Resistance to earthquakes, if required, shall be particularly specified. 5 Electrolyte levels 5.1 Each cell shall be equipped with a device to indicate the minimum and maximum electrolyte levels. 5.2 For containers made of translucen
32、t material, the minimum and maximum levels shall be indicated on the container wall. 5.3 For containers made of an opaque material, a gauge shall be provided indicating the position of the electrolyte level in relation to the minimum and maximum levels. 6 Electrolyte reserve 6.1 The electrolyte rese
33、rve (see 3.1), together with the battery design and the charging method used, governs the frequency of inspections for electrolyte level readjustments. 6.2 For batteries in float operation (see 8.1) the minimum electrolyte reserve is specified in Item d) of 8.2. Page5 EN6089611:20037 Capacity (Test,
34、 see Clause 14). 7.1 The essential characteristic of a stationary cell or battery is its capacity for the storage of electric energy. This capacity, expressed in ampere-hours (Ah) varies with the conditions of use (discharge current and voltage, and temperature). The recommended t-values are: t = 24
35、0 h, 20 h, 10 h, 8 h, 5 h, 3 h, 2 h, 1 h, 0,5 h. From these various C rtvalues one value may be selected and declared as rated capacity C rt (see 3.2). 7.2 The most commonly used values of t are between 10 h and 3 h. For these, the final voltage (end-of-discharge voltage) shall be U f= 1,80 V per ce
36、ll (unless otherwise recommended or requested by the manufacturer or user). For other discharge rates, the recommended value of U fshall be set by national standards or shall be stated by the manufacturer together with the value of C rtor together with the particular performance data (see 7.5). 7.3
37、The discharge current corresponding to the rated capacity C rtat the chosen reference temperature 20 C or 25 C is: I rt= C rt/ t (A) to the final discharge voltage U fin accordance with 7.2. 7.4 The actual capacity C ashall be determined by discharging a fully charged cell or battery in accordance w
38、ith Clause 14. The resultant value shall be used for comparison with the rated capacity C rtstated by the manufacturer, or for control of the state of a battery after long periods of service. 7.5 The determination of the actual capacity C ain accordance with Clause 14 may also be used for comparison
39、 with particular performance data indicated by the supplier. In this case the current I rtin 14.4 shall be substituted by the particular current corresponding to the relevant performance data. 8 Suitability for floating battery operation (Test, see Clause 15). 8.1 Stationary batteries are mainly use
40、d in floating operation A battery in floating operation has a constant voltage U flo , permanently applied to its terminal which is sufficient to maintain it in a state close to full charge and is intended to supply a circuit whose normal power supply may fail. Suitability for this operation shall b
41、e checked by a test carried out on cells or on batteries. Batteries which are not in true floating operation (for example, solar power storage) should not be qualified according to the test method described in Clause 15. Page6 EN6089611:20038.2 Batteries operating in continuous floating operation Ba
42、tteries operating in continuous floating operation according to Clause 15 shall meet the following requirements: a) the electrolyte densities shall remain within specified limits in all cells; b) the individual cell voltages shall remain within specified limits; NOTE In some batteries with monobloc
43、design the voltage of individual cells cannot be measured. In those cases the assessment of uniformity should be made with the voltage of individual monobloc units. c) after a period of six months the actual capacity C aon discharge according to Clause 14 shall be at least equal to C rt ; d) after a
44、 period of six months the loss of electrolyte shall not exceed 50 % of the volume between the minimum and maximum levels. The volume between the minimum and maximum levels shall be available from the manufacturer. 9 Endurance See definition 3.4. Depending on the battery and system application an end
45、urance test based on discharge- charge cycles or an overcharge shall be carried out. 9.1 Endurance in cycles The endurance in discharge-charge cycles shall be tested according to Clause 16 where frequent discharges of the battery are to be encountered due either to a deliberate choice of operational
46、 application or to frequent power-line outages. The minimum requirement of the test shall be two sets of 50 cycles each (N = 100 cycles) before capacity drops below 0,95 . C 10where C 10is the rated capacity at the 10 h-rate Optionally, the manufacturer may state the number of cycles as C a= 0,8 . C
47、 10 . 9.2 Endurance in overcharge The endurance in overcharge shall be tested according to Clause 17 where natural overcharge related potential failure modes such as corrosion of grids, plate group bars or terminals of the battery are to be encountered due either to high ambient temperatures, poor f
48、loat voltage regulation or similar. The minimum requirement of the test shall be six periods of 720 h each before the capacity drops below 0,8 C where C is the rated capacity at the 1 h rate to U fas defined in Clause 7. 10 Charge retention Although, in the majority of cases, stationary batteries ar
49、e on permanent charge, it is useful to establish their capability to retain charge by means of a test for cases where the battery may become electrically disconnected either normally or accidentally. Page7 EN6089611:2003The charge retention shall be determined according to Clause 18 and expressed as C R= per cent of the initial capacity C a . The minimum value C Rshall be in accordance with the applicable product standard or as indicated by
