Change Capacity in Specialized discharge profile battery model

I am using a 12v 245AH battery model with discharge profile battery in Simulink. The actual battery capacity does not reflect on the discharge profile plot as attached. Kindly let me know if I am missing or needs a tweak.

Hello Gokul,

I believe what we are seeing responds to the definition of the different types of capacities. e.g. total, discharge, nominal, etc.

If you are referring to the fact that the x-axis is ~255 Ah at the end of the discharge, I believe the reason is that the maximum capacity for the block has been defined as the capacity obtained at low C-rate until the cut-off voltage value has been reached, which looks close to the 245 Ah that I would expect to see.

Please let me know if I misinterpreted your inquiry.

Best regards,

Javier
