PURPOSE:To enhance the life characteristic for charging/discharging cycles under rapid charging by starting a forced charging timer when the charge current has sunk to a specific sensing current, charging with a constant current below the sensing current, and by finishing the charging when the timer is ended. CONSTITUTION:In constant-voltage, constant-current control with the charge current under 2.0CA, the charge sensing current is set below 0.20CA, and a forced charging timer is started when the charge current has sunk to the sensing current. During the timer in operation the charge shall be made with a constant current below the charge sensing current, and the charging electric amount at this time is within 10% of the battery capacity, and the charging is finished after the time has gone out. Thus a proper balance of the charging electric amount for the discharge electric amount is obtained even in case with a large charging current by setting the charge sensing current and forced charge timing to appropriate values, that should enhance the life characteristic for charging/ discharging cycles of a battery. |
