The definition of vampire drain is energy usage while not in use. The general purpose of a vehicle is to be driven, thus energy used outside of that purpose is vampire drain.Sorry, I wasn't clear. Obviously cabin temperature doesn't have anything to do with the battery health. What I'm saying is that the act of conditioning the cabin affects the battery temperature. So there could be logic in the BMS that says, if temps in cabin/battery drops below a certain level, run the heat to warm up.
The broader point I'm making is that I don't think what we're talking about is truly "vampire" drain in that it is just completely wasted energy (like a leak in a gas tank). A very small amount might be, but I think the majority is going to a purpose, whether it be communications, battery management, whatever. People may disagree with that purpose, whatever it is, but I don't think drain at the level of 5kwh per 24 hours is just evaporating into thin air.
The truck shouldn't be doing anything while not in use and while not told it will be in use soon, that causes fans or pumps to need to run while sitting in weather between 40F and 70F. But it is.
