Abstract
A refresh charge control device which counts a time after achieving a fully charged condition of a battery by last refresh charge and an accumulative value of a charge and discharge electric current. Plural relationship between the time and the accumulative value is determined as conditions for carrying out the refresh charge of the battery. When either one of those relationship is established, the refresh charge of the battery is performed for fully charging the battery. It is judged whether a condition that a vehicle speed is equal to or faster than a predetermined vehicle speed continues for a predetermined time. Even the condition that the vehicle speed is equal to or faster than the predetermined vehicle speed continues for the predetermined time, the refresh charge of the battery is performed for fully charging the battery irrespective of the relationship between the time and the accumulative value.
