For regular battery constant current charge tests,when you use constant voltage to charge the battery, the current flows into the battery becomes smaller and smaller as time goes by, right?
There must be a point for you to stop the charge, the end condition of that point is supposed to be a very small current.
That’s why for CV_Chg the end condition is current, that’s a necessary set up.
But that’s just for NORMAL tests, what if you want to do the tests without setting up the current end condition?
Such as if you need a step to simply hold voltage at 2.7V for extended amount of time.
What can you do with that? Is it possible for Neware BTS software(Battery Testing System) to get the job done?
The answer is YES!
For achieving this purpose, you have to modify the BTS.ini file in the installation directory.
Please close the BTS application firstly, go to the installation directory(normally C:\Program Files (x86)\NEWARE\BTSClient7.5.5) and open the BTS.ini file.
Locate the following segment and modify the value from 0 to 1.
[CVCHARGEMODE]
MODE=1
Then save the BTS.ini(you may be asked for the administrator rights if you are using Windows 7 or higher edition of Windows OS).
Restart the software and you’ll notice now the CV_CHG can work without setting up the current end condition.
BTW: As you may already knew, long time Chrage/Discharge may cause hazards to battery or supercapacitor, please be careful.
