23、ice in fixed locations (.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 a p p I i ca t i o n s a re ca I I e d “s ta t i o n a r y batter i e s I. Any type or construction of lead-acid batte
24、ry 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 corresponding test methods associated with all types and construction modes
25、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 of tests are given in Table A.2. Statements and claims of basic performa
26、nce 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. For dated references, only the edition cited applies. For undated referen
27、ces, the latest edition of the referenced document (including any amendments) applies.

29、he 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 quantity of electricity, declared by the manufacturer, which a cell or battery can deliver under specified cond
30、itions after a full charge. This value is usually expressed in ampere-hours (see crt I EV 486-03-22) 3.3 nominal capacity C,om suitable approximate quantity of electricity used to identify the capacity of a cell or battery. This value is usually expressed in ampere-hours (see IEV 486-03-21) 3.4 endu
31、rance 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 withstand mechanical stresses during normal transportation and hand
32、ling. 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 translucent material, the minimum and maximum levels shall be indicated
33、 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 reserve (see 3.1), together with the battery design and the charg
34、ing 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. Page 6 EN 60896-112003 7 Capacity (Test, see Clause 14). 7.1 The essential characteristic of a sta
35、tionary 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 = 240 h, 20 h, 10 h, 8 h, 5 h, 3 h, 2 h, 1 h, 0,5 h. From thes
36、e various C, values one value may be selected and declared as rated capacity C, (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, = 1,80 V per cell (unless otherwise recommended or requested by the manufact
37、urer or user). For other discharge rates, the recommended value of U, shall be set by national standards or shall be stated by the manufacturer together with the value of C, or together with the particular performance data (see 7.5). 7.3 The discharge current corresponding to the rated capacity C, a
38、t the chosen reference temperature 20 “C or 25 “C is: to the final discharge voltage U, in accordance with 7.2. 7.4 The actual capacity Ca shall be determined by discharging a fully charged cell or battery in accordance with Clause 14. The resultant value shall be used for comparison with the rated
39、capacity C, stated 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 Ca in accordance with Clause 14 may also be used for comparison with particular performance data indicated by the supplier. In this case the cu
40、rrent I, in 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 A battery in floating operation has a constant voltage U, permanently applied to its terminal which is sufficient to
41、 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 be checked by a test carried out on cells or on batteries. Stationary batteries are mainly used in floating operation Batteries which are not in t
42、rue floating operation (for example, solar power storage) should not be qualified according to the test method described in Clause 15. Page 7 EN 60896-112003 8.2 Batteries operating in continuous floating operation Batteries operating in continuous floating operation according to Clause 15 shall mee
43、t 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 design the voltage of individual cells cannot be measured. In those cases the asses
44、sment of uniformity should be made with the voltage of individual monobloc units. c) after a period of six months the actual capacity Ca on discharge according to Clause 14 shall be at least equal to Crt; d) after a period of six months the loss of electrolyte shall not exceed 50 % of the volume bet
45、ween 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 endurance test based on discharge- charge cycles or an overcharge shall be carried out.
46、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 application or to frequent power-line outages. The minimum requirement of the test s
47、hall be two sets of 50 cycles each (N = 100 cycles) before capacity drops below 0,95 CIO where CIO is the rated capacity at the 10 h-rate Optionally, the manufacturer may state the number of cycles as Ca = 0,8 . CIO. 9.2 Endurance in overcharge The endurance in overcharge shall be tested according t
48、o 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 float voltage regulation or similar. The minimum requirement of the test shall be six peri
49、ods 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, as defined in Clause 7. 10 Charge retention Although, in the majority of cases, stationary batteries are 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. Page 8 EN 60896-112003 The charge retention shall be determined according to Clause 18 and expressed as C, = per cent of the initial capacity Ca. The minimum val
