Regarding the current function input.

[manjunathnilugal]

Dear all,

I have system which generates/requires electricity along with battery charging/discharging. There are drive cycles and experimental method where I can give the charging current for 't' seconds to the battery in the form of the interpolant and solve.
But, is there any alternate way of giving the current function or switch the value of current from +/- along with the running simulation with integrated pybamm model.
There is an option of starting_solution and inital_soc in the solve option, I am not aware of using it, if there are any document regarding this kindly let me know.

Not sure I fully understand your question. You can pass an interpolant (or a function) to your current. You can also work with experiments, defining "Charge" and "Discharge" steps.

You can find an example of starting_solution in this notebook.

I think this question relates to adjusting current input dynamically by some external control system. If this is the case then the solver can be used to step the solution for discrete time intervals with a fixed current input and this current input can be changed from step to step. Have a look at this script to see the step solve method and this notebook to see how to set current as an input

N.B you can also use Simulation.step

@manjunathnilugal what you had looked ok but you don't need to create all the objects inside the loop and your npts seems a bit low for the step

Sir, Thanks a lot

Thanks a lot, appreciate the help @TomTranter @brosaplanella

@TomTranter @brosaplanella Hi again,
here you will find the modified version of my code with the example code that you sent for predicting the SoC. Unfortunately on each iteration with different current_delta I always get the same values for SoC_from_n and SoC_from_p. Is it supposed to be like this or am I overseeing something.
Thanks for the help
