Hi,
I am experimenting with the bq40z50evm kit connected to two Panasonic cells in series. I'm using bqStudio 1.3.24. I am unable to get the impedence tracking functioning, unsure whether I'm missing something (not) obvious. I'm very familiar with bq20z95 & bq34z100 so didn't expect this to be difficult?
I've updated the basic flash parameters to reflect two cell pack (DA configuration), CC1 = 0, CC0 = 1
I note the IT gauging Configuration doesn't open a clickable configuration box unlike everywhere else, inconsistent UI.
In Gas Gauging I've set the design cap in mAh and cWh as well as design voltage.
I've programmed the gauge with the correct chemistry file. Calibration has also been done and matches with actuals.
Toggled FETs on, and Toggle Gauging on. Pack works, charges and discharges however RSOC stays firmly at 100%, ASOC is at 0% (?), run times to empty are max 65535 mins.
I've cycled the pack a few times with long relax periods (6 hrs) between phases. Ra tables have updated.
Has anyone seen this sort of behaviour and worked out what needed changing or might I have a duff eval kit?
Thanks for any suggestions.
