1RC battery Parameter estimation

Hello,

I'm trying to estimate battery parameter using parameter estimation application. The parameter estimation

toolbox takes a lot of time for predicting th emodel parameters also if I try performing parallel computing

or parallel pool option firstly it takes large time to initiate the simulation, further once started although it allocates

8 workers for parallel processing, it processes fails and no estimation I'm able to perform .

I want a robust model so trying to use 3 parameters with 15 data points in each parameter (corresponding to an SoC ) level.

How to resolve the issue in order to get a faster approach for battery parameter estimation

Hello Neelaish,

do you have access to this example? https://www.mathworks.com/help/autoblks/ug/generate-parameter-data-for-estimations-circuit-battery-block.html

It's for a higher order RC pair, but aligns specifically with what you are doing.

Here is some extra documentation for it: https://www.mathworks.com/content/dam/mathworks/tag-team/Objects/s/76117-sae-2013-battery-estimation-layered-technique.pdf

If these aren't helpful, are you able to share your model, or could you contact technical support and share it with them if it is not appropriate to be posted publicly?

Regards,

Joel
