Parameter Estimation for second order battery: I am trying to fill lookup tables for R1, C1, R2, and C2. Lookup tables depends on SoC and Temperature value. For now, I am only sending temperature as 20 celcius and generating SoC from input current.

Parameter Estimation for second order battery: I am trying to fill lookup tables for R1, C1, R2, and C2. Lookup tables depends on SoC and Temperature value. For now, I am only sending temperature as 20 celcius and generating SoC data from input current. I am sendind current data and trying to get estimations for lookup tables. I want to use "Parameter Estimation" tool. I am attaching simulink model. How can achieve this goal?

Hi Gökay,
If you want to fill in the lookup tables, using "Parameter Estimation" is probably not the best approach. A lookup table is typically used because you have data from a spec sheet or from experimental data. As such, you would just pull the information from the spec and put it in the lookup table.
If you need to identify the relationship between the SoC, Temperature, and R/C values you will likely want to either use a model constructed from first principles and/or some sort of curve fitting or optimization to solve for the parameters. If you have the data from a spec sheet, you may be able to just plug them into the lookup table as you have done for the 1-D Lookup Table for Temperature.
Hope that helps,
-Adam
