12V/24V/36V/48V universal smart battery charger for e-sweeper / scooter
Brief description :
1. Aluminium case , light weight
2. Input voltage ; DC 100 V ~240 V 50 / 60 HZ
3. Max wattage : 120 W
4. Charge mode : 3 stage ( CC CV float mode )
5. Charging : High saturation and efficiency
The 3-stage mode charging :
First stage ( constant current ) : The charger will supply constant current for the battery
Second stage ( constant voltage ) : The voltage will be rising under the first stage, when it reach constant
voltage value, it will turn into the second stage. The current will be slowly smaller until it reduce to floating value,
the CV stage will end.
Third stage ( Floating charging ) : When the current is approaching the value of transition, the charger will
cut down to the given current gradually, that means the battery power is full and indicator light turn to green. At
this moment, the battery can be stopped charging or keep on trickle current charing for half an hour.
