Other Parts Discussed in Thread: BQSTUDIO
Hi,
In the presentation that most people are referring to for scaling the current on slide 4 it shows an example of using scaling to support discharge currents of 48A.
"We can fool the gauge by current calibration: for a 5 mohm Rsense, if we calibrate at an actual current of 4A, we can use the value 2A for calibration so the CC Gain and CC Delta would become 10 mohm. We now have a calibration ratio of 50%"
1) For this example this procedure requires you to use a 4A load and in bqstudio we will input -2000mA (2A discharge) and click calibrate current. Is that right?
2) Once that is done, would we then go to Data memory and change CC gain and Capacity Gain 10 mohm? Or does that change automatically?
3) If I then attach a load, would the current/ average current shown in the registers tab show the actual current or half the current?
I'm asking this because if I leave the CC gain as is, then the reading of the current is half the actual current I'm supposed to see. If I double the CC gain, the reading matches up with the current I'm supposed to see,
