BQ27426: Question about the RM corresponding to the flat area

Part Number: BQ27426

Tool/software:

Hello
1, The flat area corresponds to the battery voltage (3679mV - 3803mV) will not change, as the battery ages, will the RM value predicted by FuelgaugeIC, change at the 3803mV voltage?
2, Will the RM value become larger or smaller?
3, Is there any data on the RM value corresponding to 3803mV for different aging levels?
1、平坦区对应的电池电压(3679mV--3803mV)不会发生变化,随着电池老化,FuelgaugeIC预测的RM值,在3803mV电压处是否会发生变化?
2、RM值会变大还是变小?
3、是否有不同老化程度,3803mV对应的RM值的数据?
  • Hello Wang,

    Gauge does not run simulations in the flat region so RM will not change. We do not have data for RM based on different aging levels. This greatly depends on the battery chemistry and cycles of aging.
