  • RE: BQ34Z100-R2: FCC/RC mismatch

    Hi Mathias, I notice in your Ra0 and Ra1 tables are very different. I recommend using the GPCRA0 tool to optimize these values. Were you able to capture a log file of the soc jump? Regards, Diego

  • BQ40Z80: GPCRA0 calculator using scaled current or actual current?

    TI Thinks Resolved
    Part Number: BQ40Z80 Other Parts Discussed in Thread: GPCRA0 , Hi, I’m trying to use GPCRA0 to generate gg file for bq40z80 gauge. The results have Qmax set to the actual mAh rating of the battery. With scaling factor set, I’m assuming Qmax should scale…

  • RE: BQ34Z100-G1: True FCC & True RC values changed while the battery was sitting idle

    Hi, Just because this was a custom ChemID does not meant the Ra tables cannot be improved by using the GPCRa0 tool. I would think this issue could be fixed by running more discharge cycles to allow the Ra tables to learn the cell resistance or using the…
