I see now the process - thank you for explanation, ok - with exception that transmission kinda a doing same jerking going on (when you at neutral, car still stops after injecting) and process of charging battery?!?I am guessing you had your Electric Coolant Heater replaced? Your screen shot looks normal for initial start. The ICE is running to heat the coolant, which will provide heat for the battery and to warm the cabin. The ICE is also charging the HV battery somewhat. Once the ICE turns off, all of your power flow should be from the battery. Additionally, the transmission changing back and forth that you experienced before your ECH was replaced should no longer occur. Your PacHy is now running as designed again.
But for the first injection time mostly and then only battery working.
That's additional screenshots from the start "cold" car. 45F out.
As gasoline is on & up and battery as charging and you are saying -the ICE heat coolant and cabin. Why is battery could do that? May be physic or mystery for me. ;-)
