Charging characteristic curve

This charger is designed according to the characteristics of the lead-acid battery used in the engine, and adopts a three-stage intelligent control method of constant current fast charging, current limiting, and trickle float charging. When the battery voltage is lower than the preset value, it is the constant current charging stage; when the battery voltage is higher than the preset value, the charging current decreases with the increase of the battery voltage and enters the current limiting charging stage; the battery voltage gradually increases to reach the predetermined value. Constant voltage value. When the charging current is less than 0.3A, the charging indicator light goes out and the float charge stage is entered. The subsequent charging current only offsets the self-discharge of the battery and maintains the battery in a fully charged state. There is no need to disconnect the charger, which is harmful to the battery. Life span is not affected.
