Other Parts Discussed in Thread: GPCCHEM
您好!现我司有量产bq40Z80用于磷酸铁锂电池,但是电量在静置5小时后会从充满电100%跳变到69%-73%这个范围。
请问配置LFP_RELAX=1是否可以解决这个问题。

您好,请将 .gg file and the GPCCHEM report and data submitted发过来看一下。
This is one of the main limitations of LFP type chemistries with such a flat voltage curve, everything needs to be optimized or there will be issues in estimation. I would definitely disable any of the relax smoothing or relax jump settings so the SOC doesn't jump during relaxation and the smoothing will have more time to adjust any jumps.
