SOC Estimation using coulomb counting

[Ramesh123]

Hi,

We have been developing BMS (Battery management system). Need support regarding SOC estimation.

MCU : S32k146

AFE : MC33771C

We can able to get raw measurement data from AFE. The coulomb count register gives some values.

my problem is how to estimate the soc from coulomb count values.

please support to us anyone.
