3.1.5 nickel cadmium battery secondary battery with an alkaline electrolyte, a positive electrode containing nickel oxide and a negative electrode of cadmium [SOURCE: IEC 60050-482:2004/AMD1 :201 6, 482-05-02, modified – A synonym has been removed.] 3.1.6 rated capacity, <for railway NiCd cell> C n capacity value of a battery determined under IEC 60623:201 7 specified conditions and declared by the battery manufacturer 3.1.7 state of charge SOC remaining capacity to be discharged, normally expressed as a percentage of the full battery rated capacity as expressed in relevant standards Note 1 to entry: Practical definitions of SOC are dependent upon chosen technologies. 3.1.8 depth of discharge DOD capacity removed from a battery during discharge in relation to its full rated capacity expressed as a percentage Note 1 to entry: It is the complement of SOC. Note 2 to entry: As one increases, the other decreases by the same amount. 3.1.9 ageing factor, <for railway NiCd cell> quantitative factor expressing the degradation in the ability of the battery, due to usage, to deliver electrical energy under specified operating conditions such as, but not limited to, operating ambient temperature, cycling considering depth of discharge (DOD), and maintenance practices 3.1.1 0 nickel cadmium battery information system electronic system collecting and analyzing battery data to provide additional information, i.e. information not necessary for battery operation Note 1 to entry: Additional information can be information about e.g. condition-based maintenance.
4.2.2 Sintered/PBE plate/electrode technology The sintered positive plate/ electrode is obtained by chemical impregnation of nickel hydroxide into a porous nickel sinter coated thin steel strip that is previously perforated and nickel-plated. The negative plastic bonded electrode (PBE) is obtained by the coating of slurry consisting of cadmium oxide mixed with a plastic binder onto a nickel-plated thin perforated steel strip. 4.2.3 Sintered/sintered plate/electrode technology The sintered positive and negative plate/electrode is obtained by chemical impregnation of nickel hydroxide and cadmium oxide into a porous nickel sinter coated thin steel strip that is previously perforated and nickel-plated. 4.2.4 Fiber plate/electrode technology Both the positive and negative plates/electrodes consist of non-woven fibers of nickel or nickel-plated plastic fibers of high porosity. 4.2.5 Pocket plate/electrode technology Both the positive and negative plates/electrodes consist of several flat, perforated metal pockets made from perforated steel strips linked together encapsulating the active materials.
