BQ33100: BQ33100 Super Capacitor Manager

BQ33100: capacitance learning data flash settings

Prodigy 10 points

Part Number: BQ33100
Other Parts Discussed in Thread: BQEVSW

The following are the relevant configuration settings

SuperCap 2.7v 50F

There are two packs 

1. 2P4S

2. 4P4S

CHGLV0

CHGLV1

Vstack

10.36

10.79 

When the measurement is completed, Capacitance is obtained 

4P4S 2P2S
0x1A(26) 0x0D(13)

2P4S expected to be 2 * 50 / 4 = 25 

4P4S expected to be 4 * 50 / 4 = 50 

ESR also has a wide range of values

May I ask how to correctly set the data flash to get the correct value?

    Hello Kenny,

    Please share your .gg file as well as the procedure you used to capture the estimates, if you have a log that would be best.

    Sincerely,

    Hello Kenny,

    It looks like the learning is okay, but I noticed your voltage stays constant for a period of the discharge, which shouldn't be the case. I think this may be throwing off the gauges calculations for capacitance and ESR .

    Sincerely,

    I noticed that the units represented by bqEVSW are somewhat different from those on the bq33100 datasheet, such as Capacitance (0x10).

    I have additionally set the value of the Current Calibration, which will change the Cap and ESR. Can you suggest or provide the flow and method of the current calibration?

    Hello Kenny,

    BQEVSW should provide a calibration plugin to help with this. The units in the software should be referenced since it is generated with the firmware.

    Sincerely,

    Hello Kenny,

    Anything you change from default will need to be updated during production programming. You can see the defaults in BQEVSW by going to the Data Flash tab then the Data Flash bar on the top left to show defaults.

    Sincerely,

    Wyatt Keller
