Using batteryParametersLUT function to determine ECM parameters with HPPC discharge test

Hello, I am trying to use the batteryParametersLUT function as described in the 'Characterize Battery Cell for Electric Vehicles' example to determine the parameters of an RC equivalent circuit model, is it possible to generate parameters for an HPPC dataset that is using discharge pulses only, as opposed to discharge and charge pulses? The charge current (in Amperes) is an input of the batteryParametersLUT function, however when setting this charge current to zero, an error is thrown because the charge pulse array is obviously empty, so wondering if there is a workaround or whether the function can only be used on HPPC data that provides discharge and charge pulses.

Hello Lily,

I believe the issue is that your block has current directionality enabled. This duplicates the parameter fields to separate charge from discharge. Would you kindly try to disable it (third field from the top) and see if the problem persists?

Best regards,
