How can I draw current pulses from a battery in Simulink Electrical to discharge the Li-ion battery?

So I have battery model and I want a block that will draw a current at regular time intervals from that battery.

thanks.

Hi Nishen,

Can you please tell your battery model so, that I can assist you better.

Dear Srija,

Thank you so much for getting back to me.

I have attched my model here.

It currently has a constant current to observe the discharge of the battery, however I want to know how the discharge would look like if the current has a train of pulses.

Thank you.

Best Wishes,

Nishen.

Hi Nishen,

You are using the current source block, which can only generate DC and AC waveforms, but not pulse waveforms. So instead of using current source block, you can use the controlled current source block and a pulse generator block and connect these two using a Simulink-PS converter.

These links can be helpful:

Controlled Current Source - Ideal current source driven by input signal - MATLAB (mathworks.com)

Pulse Generator block - Generate square wave pulses at regular intervals - Simulink (mathworks.com)

The attached Simulink model might be helpful:
