How to estimate SoC for using kalman filter (Simscape Battery)

Hello Everyone,

Currently, I am trying to develop BMS fot battery module. My application is 37V, 950 AH and some series and parallel Arrangement. For example, I am using 20 cells in series connection and trying to measure SoC for using Unscented Kalman filter and SoH in Simscape battery toolbox. My question is that I will use individual SOC (Kalman filter- block) block for each cells or how to arrange so I will get SOC and SOH value for 20 cells. If you have any example so please share it or any method or step to estimation state function ?

Thank you !

Hi,

You can refer to the following documentation link for a better understanding:
