5.5.8.23.3 Common Response Parameter
If the WeldingDetectionRes contains EVSEPresentVoltage the VC-EVCC sets the value in
the CAN signal VCVCCU_V2G_EVSEPresentVoltage.
5.5.8.24 Session Stop
The VC-EVCC proceeds with the SessionStopReq
 Vehicle_ContactorVoltage is less than 60V or
 WeldingDetectionRes is received five times in the correct loop sequence and
 VCVCCU_DigitalInput_DebouncedStatus is pressed or
 VCVCCU_S3Switch_DeboundedStatus is pressed (only in case of Combo1) or
 VCVCCU_Vehicle_StopCharge is pressed (only if feature is activated).
