Hi,
i want to model a battery pack with thermal effects. i want to discharge it at various rates( called C rates, 1C,2C,3C..). Which simulink block will be used for that purpose, please guide me.
Thank you.

Thanks for responding. Please tell me which simulink block or by which way i can discharge the battery pack at various rates ( C rates).

Hi Sudeep,
We can use Controlled Current Source block, Ideal current source driven by input signal - MATLAB (mathworks.com), to specify the current we want to use to charge and discharge the battery (pack). If we know the rated capacity (in Ah) of the battery, we can easily convert C rate to current in A.
The following example uses this Controlled Current Source block to specify the current for CC-CV charge and constant current discharge. Battery Charging and Discharging - MATLAB & Simulink (mathworks.com).
Best wishes,
Xiangchun
