Zusammenfassung:	According to one embodiment, a charging device includes: a battery controller, an executor, a voltage measurer, a voltage corrector and a diagnoser. The battery controller controls charging of a storage battery. The executor charges the storage battery using the battery controller and changes a charge rate of the storage battery in a case that a predetermined condition is established during a time period when the storage battery is charged. The voltage measurer measures a voltage of the storage battery during a time period when the storage battery is charged by the battery controller. The voltage corrector corrects the voltage measured by the voltage measurer on a basis of a value of a current rate at which the voltage is measured. The diagnoser diagnoses the storage battery on a basis of the voltage corrected by the voltage corrector.
