Hello Dear,
I have used DIN70121 in OpenV2G with many chargers with almost no problem except Heliox 50kW depot charger. SessionSetup, ServiceDiscovery and PaymentServiceSelection states are successful but in ContractAuthentication state, charger never returns "finished" for the process, always sends "ongoing" and after about 10-15 seconds the communication is terminated with "EVSE_EMERGENCY_SHUTDOWN". Even if I just bypass this state, EVSE never becomes "EVSE_Ready" in next states (cableCheck, preCharge...). There is nothing to authenticate, actually it is a dummy state just to pass, because there is no RFID reader or something else for authentication. Same charger works with some other devices successfully. Do you have any idea about why the charger does not pass Authentication state although there is not any real authentication issue?
Thanks for reading,
Yusuf
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
the OpenV2G code is purely about sending and receiving data based on C structs.
Whether a charger never returns a response is not something which is part of this library.
