21、ications .17 Bibliography18 Page3 EN62259:2004INTRODUCTION Traditionally the manufacturers and users of alkaline secondary cells and batteries have expressed the current used to charge and discharge these cells and batteries as a multiple of the capacity. For example, a current of 20 A used to charg

22、e a cell with a rated capacity (C Ah) of 100 Ah would be expressed as C/5 A or 0,2 C A. This method of current designation has been used in earlier standards relating to alkaline secondary cells and batteries. Comments have been made, however, that this method of current designation is dimensionally

23、 incorrect in that a multiple of the capacity (ampere-hours) will be in ampere- hours and not, as required for current, in amperes. As a result of these comments, the method described in IEC 61434 has been used in this standard. In brief, the method states the reference test current (I t ) is expres

24、sed as I tA = C n Ah/1h where C nis the rated capacity declared by the manufacturer in ampere hours (Ah), and n is the time base in hours (h) for which the rated capacity is declared.

25、ISMATIC SECONDARY SINGLE CELLS WITH PARTIAL GAS RECOMBINATION 1 Scope This International Standard specifies marking, designation, dimensions, tests and require- ments for vented nickel-cadmium prismatic secondary single cells where special provisions have been made in order to have partial or, under

26、 very specific conditions, full gas recombination. NOTE In this context, “prismatic“ refers to cells having rectangular sides and base. When there exists an IEC standard specifying test conditions and requirements for cells used in special applications and which is in conflict with this standard, th

27、e former shall take precedence. 2 Normative references The following referenced documents are indispensable for the application of this document.

36、king 5.1 Cell designation Vented nickel-cadmium prismatic secondary cells with partial gas recombination shall be designated by the letter K which signifies cadmium, followed by the letter G which signifies partial gas recombination, and followed by a letter L, M, H or X which signifies: low rate of

37、 discharge (L); medium rate of discharge (M); high rate of discharge (H); very high rate of discharge (X ). NOTE These types of cells are typically but not exclusively used for the following discharge rates: L up to 0,5 I tA, M up to 3,5 I tA, H up to 7 I tA, X up to and above 7 I tA. This group of

38、three letters shall be followed by a group of figures indicative of the rated capacity of the cell in ampere-hours. Cells that have been tested at 20 C and 5 C but not at 18 C shall carry an additional marking of T5. For example: KGH 185 or KGH 185 T5. Cells in cases of plastic material shall be des

39、ignated by the letter “P“ after the figures. For example: KGH 185 P or KGH 185 P T5. 5.2 Cell termination This standard does not specify cell termination. 5.3 Marking Each cell or monobloc shall carry durable markings giving the following minimum information: designation as specified in 5.1 (In addi

40、tion, it is permissible for a manufacturer to use his own designation); name or identification of manufacturer or supplier; positive terminal: either a red washer or an indented or raised symbol, (see IEC 60417- 5005 DB-2002-10. 5.4 Safety recommendations The manufacturer shall provide recommendatio

41、ns for the safe handling of the cell. See also IEC 61438. 6 Dimensions No preferred dimensions are specified in this standard.
