This lead-battery charger is professional designed according to the power battery of electric vehicles epuipment. It use the advanced soft switch technology,with small size,easy to installable, high conversion efficiency, running fully loaded for a long time,stable output current,large capacity,high reliability,long life features etc. With short-circuited protect,low-voltage protect,overheated protect function.
The long delay digital counter can ensure the battery from the constant voltage to the float charge reliably every time.
Pre-charge mode: In order to protect the battery and extend its life, the battery’s internal resistance is too large or voltage is too low because the discharged time is too long or it is not used for a long time, the charger will supply low output current for the battery automatically. When voltage of the battery rises to the given voltage value, the charge mode will turn to constant current charge mode automatically.
Constant current mode: The charger supply constant charge current for the battery.
Constant voltage mode: Using the pulse width modulation(PWM) tech to control the charging current and output voltage of the charger which ensure the battery is fully charged and avoids over charging.
Floating charge mode: When the voltage of the battery is approaching the value of the constant voltage mode, and the current cut down to the given current gradually, that means the battery power is full, then the pilot lamp will turn green and the fan will stop working.The charger will turn the mode into floating charge mode automatically. At this moment, the battery can be stopped charging or keep on floating charge for half an hour.
