I am planning to simulate a circuit configuration in Simulink to implement regenerative braking before conducting a direct experiment. In the actual experiment, I am using a supercapacitor, and since Simulink has a Supercapacitor block, I am using it.
When setting the parameters of this supercapacitor block, I encountered an issue. In the self-Discharge settings, under Discharge, there is a parameter called "Current prior open-circuit." What does this "Current prior open-circuit" mean? This parameter significantly affects my experimental results.
I would like to simulate this as closely as possible to the specifications of the actual supercapacitor I am using, but I cannot find this parameter in my datasheet.
MathWorks Help Center provides a brief description, saying, "Current prior to an open-circuit event, in amperes," but I still don’t understand what this entails. Some people call it "Leaked current," but this does not seem to match the parameter's name.
What capacitor performance metric does this parameter indicate, and how can I verify this parameter? If anyone knows about this parameter, please let me know.
Thank you for reading.
