ABSTRACT OF THE DISCLOSURE A charging control apparatus comprising a switching circuit for controlling a charging current from a charging power source to a storage battery. A reference voltage is provided which increases with a ramp corresponding to a value equal to, or more than, the maximum ramp value of the charging characteristic of the battery and a reference voltage is also provided which increases with time with a ramp corresponding to a value equal to, or less than, the minimum ramp value of the charging characteristic. The terminal voltage of the battery is sensed by a voltage sensor. A first comparator compares the reference voltage and a first sensed voltage from the voltage sensor. The ramp of the reference voltage is switched in accordance with the output of the first comparator. A second comparator compares the reference voltage and a second sensed voltage from the voltage sensor. The switching circuit is controlled by the output of the second comparator. - 15 -
