RFNC8 poloso Laptop battery charging box station manual with 16 channel RFNC7 for over 95% laptop reset the battery

Summary

     RFNC8 is a multifunction device designed specially for intelligent laptop battery testing and management. After the device is powered on, you just need connect it with computer through 

USB cable, and then according the battery management software we provided, you can control and manage 16-channel batteries to work.

•  Supporting 16-channel batteries charge at once.

 • Supporting charge, discharge, test, capacity correction, charge/discharge 50% capacity

 • Real time update cell data,LED indicates working status.

 • Obtain accurate detailed information about each batteries and visual display on the 

    software interface directly.

 •  Real time draw record battery curve.

Parameters

 1. Charging 

Battery charging points following stages,the initial battery charge mode depending on battery starting voltage,the 

charging process may not need to activate and precharge

1) Pre-Charge

       Condition:Single voltage is less than 3000mV

2) Constant Current

Condition:Single voltage 3000mV-4200mV, enter the fast charge,current depend  

on the capacity.

3)  Termination

At the end of charge:Constant voltage charging current will gradually decrease,

when the current less than termination current or power comes to 100%, and the 

current less than 1A, end of charge.

2. Discharging 

Internal constant current discharge,discharge current default is 500mA, up to 3A.You can set the discharge current 

through RFNC8 software ,bias may exist between the set point value and the actual value,specific value related with 

the battery.

3. Testing

By charging and discharging the battery in short time,test whether the charge/ discharge function is good. Charging 20s, discharging 10s.

The LED flash green after test successful,and the software prompts pop.

The LED flash red after test fails,and the software prompts pop.

4. Capacity Correction

After several recycling the battery,the actual power consumption and battery management chip records deviations. When the deviation reaches a certain level will affect the normal use. Power correction via a fully discharged battery to correct the record power management chip value,and full charging for battery.

5. Stop

Stop the current job status

6. CD50% & DC50%

        CD50%:After the first battery charge and then discharge to reach 50% of full charge capacity.

        DC50%:After the first discharge capacity of 50% is charged to the full charge capacity

7.  LED Instruction

Green light:Normal charge

Green flash:Task completion

Red light:Normal discharge

Red flash:Abnormal alarm (Reasons: No current charge, no current discharge,working overtime or activation fails)

 8.   Intelligent Protection

1). Over current protection, over voltage protection:

Under normal circumstances the current and voltage are within the limits, even though this part of the circuit malfunction,power outlet at the fuse can also ensure that the output current does not exceed 3A.

2). Circuit protection:

Hardware short-circuit protection,when the battery is reversed or shorted out, 

not powered.

3). Active cooling:

Discharge status,(If the current exit)Fans starting;

Other status,when the temperature is higher than about 48 ℃ fan starts, when 

the temperature is below about 40 ℃ fan stops.

4). Abnormal Alarm:

Termination function being executed when an exception occurs, and the LED flashes red

• Ø Charge function,for a period of time (about 50s) there is no current
• Ø Discharge function,continue for a period  time (about 25s) there is no current
• Ø charging more than 8.8H
