What is the right way to obtain SOC values during the experiment?

[cyasing]

I can see SOC being used in the source code as a variable, as well as initial SOC, but how can I change initial SOC and extract SOC from solution within a script?

There is no SoC variable built in PyBaMM as there are multiple definitions, but you can get the SoC according to your own definition by using postprocessing the solution (e.g. dividing the Discharge capacity [A.h] by the total capacity).

[cyasing]

You mean (Discharge capacity from solution) / (Nominal cell capacity from parameters) right?

[brosaplanella]

Yes, though if the battery age you might want to update the value for the cell capacity.

[cyasing]

By step solving or summary variables, then?

[brosaplanella]

Whichever way you choose to define your capacity (different people use different definitions).

Right
