Refresh charge control device and method
First Claim
1. A refresh charge control device comprising:
- a time count device that counts a time after achieving a last fully charged condition of a battery;
an accumulative electricity use amount count device that counts an accumulative electricity use amount of the battery after achieving the last fully charged condition of the battery; and
a controller that starts a refresh charge of the battery when the time counted by the time count device and the accumulative electricity use amount counted by the accumulative electricity use amount count device satisfy a predetermined relationship.

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.
