Tool/software:
We are using the bq27541G1 gas gauge in one of our products. We have our board supplier programming the batteries, and have been finding issues with RSOC in some of them. In some cases, our batteries are showing 100% RSOC when they should be around 25%. In others, they will come back from being cycled with a 25% RSOC, but then it drops to or close to 0 very quickly. A review of the flash settings (gg file) found nothing out of ordiinary, with the only differences between a known good and a failure in variable fields (Calibration constants, Lifetime data, etc. A failure of each type was programmed with a golden SREC file, and both worked properly aftward. Attached are SREC files pulled from a known good and one of each of the failure types. We don't have the ability to understand what has changed between SREC files from one battery to another that are constant values. Is there any way you can review and point out any programming errors that might cause the failure modes?PulledFilesSCP0570117.zip
