ABSTRACT:
A method of charging a secondary battery by applying the voltage pulses higher than a rated terminal voltage of the secondary battery at predetermined intervals so that a charging current intermittently flows through the secondary battery while the peak value or pulse width of the charging current is controlled as the voltage measured across the terminals of the secondary battery at the intervals when the the voltage pulses are not applied steppedly is made higher.
