I saw the same effect but living in Alabama, it works to keep it on or you’ll really suffer on the next trip. Imprecise, I’m seeing about 1.1-1.4 kWh every 3-4 hours depending on sun/shade. But those black seats will burn your back and butts without it. Yes, remote conditioning will cool cabin air but not those black seats. Bob Wilson
Most of my shifts start leaving a cool home garage before sunrise and I park the car in a large multilevel parking garage at work. So rare direct sunlight outside of driving home from work and parking on errands/shopping. Since others are reporting substantial vampire drain with cabin overheat protection activated but not hitting threshold temps to be used, i’ll keep it off for now to see what happens.
I'm confident it is from the usable, displayed capacity. My EVSE has wireless management so I can track the kWh put in the car. Bob Wilson
that seems odd, as 1% would be less and less depending on battery charge. i wonder why drain wouldn't be a constant.
I'm no physicist, but I'm guessing it would be like a pool of water. Still going to get the same evaporation rate regardless of how big the pool is (given the same exposed surface area ratio). Think Olympic size pool compared to baby pool. Both can evaporate at the same rate.
The operative word in the manual is "MAY" not "WILL." Vampire drain is a function of how an owner configures and uses their car. Anecdotal evidence appears to confirm that the amount state of charge can also affect vampire drain. I shut everything down on my car when unattended, don't check up on it frequently through the app (I don't "wake it up"), generally leave my car at 30% - 70% SOC, and only rarely charge it outside of my home and I don't experience any noticeable drain. Window tinting? I have white interior with no aftermarket window tinting - cool, cool, cool.
