A charging apparatus may include an increase and decrease unit configured to increase and decrease charging current to the storage battery; a detection unit configured to detect a temporal change of a voltage or current supplied from a power generation source to the power conditioner; and a control unit configured to control the increase and decrease unit to increase the charging current over time, to continue increasing the charging current when a temporal amount of decrease of the voltage or current detected by the detection unit is smaller than a predetermined threshold, and to decrease the charging current by a predetermined amount when the temporal amount of decrease of the voltage or the current is equal to or larger than the predetermined threshold. |
