ABSTRACT:
A method for charging a storage battery includes providing an electric charger having a rapid charge voltage level and a trickle charge voltage level, a total-timer for measuring a total time which has elapsed since initiation of a charging operation, a peak-timer for measuring an amount of time which has elapsed since a peak voltage is reached during rapid charging of the storage battery, and an arithmetic circuit in the peak timer for determining a function of an elapsed time and a value of a charging rate. The arithmetic circuit of the peak-timer determines an elapsed time value of the peak-timer as a function of an elapsed time value of the total-timer and a value of a charging rate. The elapsed time value of the peak-timer is initially set at substantially the same time as an initial setting of a value of the total-timer. The peak-timer is started at a predetermined elapsed time after starting of a rapid charging operation.
