Drawing power out of CCS port

Summary

Then it turns off, but a new session can be established after disconnecting and re-connecting the plug. Did a session where I connected two bulbs with 230V/60W in series, and also here, the car shuts down after 10 minutes. image.png Edit: After the 10 minutes, the car reports CurrentDemandReq DC_EVStatus.EVErrorCode 5, which is FAILED_ChargingCurrentdifferential. Maybe it helps to better simulate; at the moment my EVSE mode reports too much voltage and too much current in the CurrentDemandResponse. Today I have a chance to revisit this again, this time with MG4 electric (2023). The set up same as before, CCS2 with only communication protocol runing. The car stay connected in the charging session, with no power transfer and without any complaint. II run the test for 15 miniutes, before stop it. Set up: Session screen, show with no power: Next step is to draw some heavy current out of this car and see if it trigger any alrm or HV fault, EDIT 1: Latest test, I run the session for 2 hours without any complaint, DC pin voltage 355 v (without load) EDIT 2: Tested with 2 ligh bulb in series (60+60w), run the session run for 2 hours no complaint, the MG4 seem to be OK with the fact that SoC reduced rom 43% to 42% in 2 hours while fast charging. EDIT 3: Confirmed with 5kW heater, test only for 5 minutes. SoC reduced about 4% during discharged. I can observe a lots of energy has been transfer out from MG4 battery during this 5 minute. No error reported, the car operate as normal. Edit 4: Tesla & BYD Atto3 also OK now Edit 5: 5kw V2L with MG4 Edit 6: 5kW V2L with Tesla-Y
