Hello everyone,

I am trying to implement the Battery Pulse sequence object for the dataset I have currently.

The example dataset consists of 26 pulses and my dataset has 11.

When I am trying to implement the Pulse sequence object to my dataset, I am ending up with the following error message:

"Index in position 1 exceeds array bounds. Index must not exceed 11.

Error in Battery.PulseSequence/createPulses

Error in Trial_script_test_data (line 30)

psObj.createPulses('CurrentOnThreshold',3) %minimum current magnitude to identify pulse events"

How and where do I define the pulses as 11 in 'createpulses'

psObj.createPulses(...

'CurrentOnThreshold',3,... %minimum current magnitude to identify pulse events

'NumRCBranches',2,... %how many RC pairs in the model

'RCBranchesUse2TimeConstants',false,... %do RC pairs have different time constant for discharge and rest?

'PreBufferSamples',2,... %how many samples to include before the current pulse starts

'PostBufferSamples',4); %how many samples to include after the next pulse starts

This is my version of the script.

Hi @Simha Sreekar,

Will this help you out, Simulink.SubSystem.convertToModelReference

Hoping to see @Manikanta Aditya expertise resolving this problem.

Hi @ Simha Sreekar,

No problem. Hope, this is what you are looking for, Battery.PulseSequence

Hi @Simha Sreekar,

It appears that you have loaded the data from the example file and are trying to add pulses to the same 'Pulse Sequence' object.

Try creating another 'Pulse Sequence' object and then load the data from your personal files. Here is the code for your reference:

psObj = Battery.PulseSequence;
FileName = '<Insert personal MAT file name here to add your pulse data>';
[time,voltage,current] = Battery.loadDataFromMatFile(FileName);
addData(psObj,time,voltage,current);
psObj.createPulses(...
    'CurrentOnThreshold',3,... 
    'NumRCBranches',2,... 
    'RCBranchesUse2TimeConstants',false,... 
    'PreBufferSamples',2,... 
    'PostBufferSamples',4); 

To change the number of RC branches you can use the 'createPulses' function and edit the 'NumRCBranches' parameter.

For more information here is the documentation for generating appropriate parameter data for your circuit: https://www.mathworks.com/help/autoblks/ug/generate-parameter-data-for-estimations-circuit-battery-block.html

Hello @Umar

Thanks for your assistance. I am able to generate the data, working on the accuracy.
