With explanation.
Charger carries out following charging operations to rechargeable battery：
1. wrong battery detecting
Quality for detecting battery to be charged.Mistake battery automatic identification simultaneously reports an error, when charger opens charge function
The preceding voltage for first recognizing battery to be charged, when the voltage that the charger detects battery to be charged is higher than 15V, is then determined as mistake
Battery；Charger can send false alarm by indicator lamp or buzzer, and reminding user's access cell voltage is too high can energy loss
Bad charger.
2. devulcanization
Effectively repaired for slightly vulcanizing battery.
The hard crystalline solid of one layer of white of surface attachment of negative plate inside lead-acid accumulator, can not still be peeled off after charging
Negative plate surface conversion is the lead sulfate of active material, here it is sulfation, referred to as " vulcanization ".
Devulcanization fills mode using arteries and veins, specially charges 1 second and discharges 0.5 second, if battery in a charge and discharge process
Voltage change then terminates devulcanization into low current priming mode less than 2V.When the devulcanization time reach default 4 it is small when after, fill
Electrical equipment also can be automatically into low current priming mode.
3. low current preliminary filling
When the voltage of battery is less than 10V, charged using 1A low current.
4. constant-current charge
The rechargeable battery main charging stage, lower in this mode to be charged using maximum current, 70%~85% electricity is at this
Stage completes, can quick charge charging.
5. constant-voltage charge
After constant-current charge terminates, cell voltage reaches a constant voltage, and the voltage for keeping this constant fills to battery
Electricity, during constant-voltage charge, cell voltage meeting more and more higher, electric current can be less and less, when charging current drops to a certain set
During definite value, constant-voltage charge terminates, and is then transferred to next stage charging, and constant voltage charging phase is exactly, to battery boost charge, to terminate
When battery be filled substantially with.
6. voltage analysis
Changed by the automatic detection battery voltage of MCU controllers 18, letter is sent if detection voltage change range is more than 2V
Breath prompting.
7. floating charge
The floating charge stage is actually also constant-voltage charge, and simply charging voltage is relatively low, electric current is smaller, category maintenance charging, is led to
Battery electric quantity can be charged to close to 100% by crossing floating charge.
8. pulse charge
When cell voltage returns to 12.9V, charged with the mode of pulse.
