Setup:
I'm new to Typhoon HIL and still learning the software. I'm simulating both the EV side and EVSE side on the same model (not on separate HIL targets) — using the ISO 15118-2 EVCC block and the ISO 15118-2 SECC block, connected through a contactor-based charging circuit model, all within one simulation. I'm testing a DC fast charging sequence.
Symptom:
The session progresses successfully up to PowerDeliveryStart, but does not move forward into CurrentDemand. EVSEPresentVoltage and EVSEPresentCurrent stay at 0 throughout, and the state machine just holds at this point rather than throwing any explicit error or fault code.
Question:
Since I'm still new to this environment, I'd appreciate guidance both on the expected signal chain and on whether simulating both EVCC and SECC together in a single model/HIL setup (rather than on separate targets) could itself be a factor here. Is there a known interlock (contactor feedback, target current/voltage validity, or IsEVReady) that must be satisfied before the EVCC block will issue the first CurrentDemandReq? What is the expected signal chain from PowerDeliveryRes to the first CurrentDemandReq inside this library block, so I can figure out where the chain is breaking?
Attached: screenshots of my EVCC, SECC(subsytem1), and root model diagrams.
