This International Standard is
33、 an amalgamation of all currently valid standards for portable sealed nickel-cadmium secondary single cells: IEC 60285, 1999, IEC 60509, 1988 and IEC 61440, 1997. It complies with the objective of reducing the number of valid standards, and does not introduce technical modifications in the original
34、standards. If, in the future, this standard is amended, the relevant original standards will be cancelled. 2. 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 ca
35、pacity. For example, a current of 20 A used to charge (or discharge) 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
36、, that this method of current designation is dimensionally 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
37、method states that the reference test current (It) is expressed as: It A = CnAh/1 h where Cn is 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.
