Original question:

BQ30Z554-R1: BQ30Z50-R1 FCC, RM, RSOC and ASOC jumps during charging and discharging

BQ30Z554-R1: Question on RB Table Availability in bq Evaluation Software for BQ30Z50-R1

Part Number: BQ30Z554-R1
Other Parts Discussed in Thread: BQ30Z50-R1, GPCRB, BQEVSW, BQ30Z50

Hello TI team:
In a low-temperature environment, I noticed that during discharge with the BQ30Z50-R1, the RSOC drops abruptly from 5% to 0%.
I would like to ask if bq Evaluation Software has a feature similar to the RB Table in Battery Management Studio that can be used for analysis or tuning.
Thank you very much.

    Hello,

    This question has been assigned within the team and will be reviewed and followed up with a application engineer when possible.

    Thank you,

    Unfortunately, GPCRB is not supported by bqEVSW for bq30z50. There is no support for temperature RbL tweaks for bq30z50. One way to work around this issue is to use Reserve Capacity (either mAh or mWh) where you remove 5% of cold temperature FCC (which may not have a large impact on room and higher temperature discharges).
