Hellow and greetings from Colombia.
I am currently developing a project involving Bidirectional DC/DC converters and DC/AC inverters, for grid-tied battery applications. the problem i found was that no matter what capacity value i choose for the battery, it discharge at the same rate with the same discharge current in both cases.
**First i tried a 5 Ah battery with a discharge current of a 100 A. The simulation last 1 second. And the SOC of the battery goes from 80% (initial SOC value) to 79.4%.
**Then, i run the same model, with the same discharge current and the same simulation time, with a 80 Ah battery this time. The SOC goes again from 80% to 79.4%
The battery's data is the following:
-Battery type: Lithium-Ion
-Nominal Voltage(V)= 200
-Rated capacity (Ah)= 5 or 80
-Initial SOC (%)= 80
Thanks in advanced for your collaboration. Have a nice day
