Generator Battery Charger

Charging according to the battery charging characteristics, using two-stage charging method. The first stage charging mode is “constant current mode”, that is, before the terminal voltage of the battery is lower than the preset value, the charging is constant current charging; the second stage charging mode is “float charging mode”, that is, after the terminal voltage of the battery is higher than the preset value, the charging current decreases with the terminal voltage of the battery. After the terminal voltage of the battery is higher than the preset value, the charging current gradually decreases as the terminal voltage of the battery rises. When the charging current is less than 0.5A and the terminal voltage of the battery gradually rises to the preset constant voltage value, the battery is basically full (charging indicator goes off), after that the charging current only offsets the self-discharge of the battery, and the long time charging is not harmful to the battery, that is, the charger can maintain the full state of the battery and ensure the service life of the battery.
