Part Number: BQ20Z95
In one of our batteries using the bq20z95 chipset, we have a few batteries that end up with low or high RSOC after being cycled. After doing some digging, I found that on these batteries the remaining capacity doesn't start changing until 10 to 20 minutes after a charge or discharge current is applied. I've compared the .gg file from a failure to a .gg file from a properly functioning battery and found no strange setting variations. What else can I look at? I've attached a quick and dirty plot of voltage, current and RM vs time from one of the defective batteries.
