The Transformation and Mathematical Graph Reflection of Lead-Acid Acu-Cell Electrical Parameters in the Equation of a Line

Many of the industrial battery producers in the laboratory follow IEC 60896-11 standard to determine two crucial parameters of the cells: internal resistance and electrical short circuit. However, the majority of producers face difficulties because they lack equipment to measure discharge rate of the large capacity batteries. Such measurement equipment’s are large expensive equipment. The purpose of this paper is to help overcome such burden by measuring internal resistance with micro impedance meter that is much cheaper and is handy-sized. After measuring internal resistance, the tension of cell that is not loaded (E≡U0) is determined and is added to the equation of a line in explicit form (y=ax + b). The latter form then is reflected in the form (E=- ri cel.I + U0), onward by transforming in other forms, such as segmental and general form, beside two parameters named above, other parameters, such as, maximum electric power and discharge rate parameters can be determined as well
