An apparatus for controlling charging of a storage battery that initially charges the storage battery in a constant current charging mode and then in a constant voltage charging mode when the charging voltage across the storage battery reaches a desired value. The present apparatus includes power supply means for operating initially in the constant current charging mode and supplying power to the storage battery, charged voltage state detecting means for switching over the operation of the power supply means from the constant current charging mode to the constant voltage charging mode when the charged voltage reaches the desired value, switching means for receiving the voltage being applied to the storage battery when the power supply means operates in the constant voltage charging mode and for dividing the received voltage at different predetermined rates to output the voltage-divided signals, and current variation detecting means for detecting a variation of the current being applied to the storage battery in response to an output signal from the switching means to output a power-off signal to the power supply means.
