Abstract

Temperature compensation methods and equipment for charging electric storage batteries are described. Control over battery charging includes measurement of battery temperature at the commencement of a charging event, and use of inflection analysis of a charger voltage-time curve to detect the attainment of a distinctive signal point in the event. To compensate for the variations with initial battery temperature on the relation of the signal point to a different battery condition of interest, control of a charging event includes use of the measured battery temperature to obtain from a controller memory information about the applicable values of process parameters pertinent to those temperature-variable process factors. The temperature of a battery charger which includes such controls preferably is used as a workable approximation to battery temperature, so that batteries of conventional construction can benefit from use of the disclosed methods and equipment.
