Beschreibung
Zusammenfassung:	A charging device for a storage battery includes: a charging power source for supplying electric power to a storage battery; charging electric power detecting means for detecting electric power charged to the storage battery; full charge determining means for making a full charge determination based on a detected value of the charging electric power detecting means; and charging controlling means for conducting charging control by charging the storage battery until the full charge determination is made, stopping charging when the full charge determination is made, restarting charging after a prescribed time period elapses from the stop of charging, and continuing charging until the full charge determination is made again. The charging device further includes temperature detecting means for detecting a temperature of the storage battery; and stop time setting means for setting a stop time based on at least the temperature of the storage battery at the full charge determination. The stop time setting means sets the stop time to be longer as the detected temperature of the temperature detecting means becomes lower.
