1 to 2 miles a day is "so much vampire drain"? I experience more than that in my PIP. Vampire drain is caused by a lot of different things, usually by user preferences in the settings in my Tesla (not available on my Prius). I experience no vampire drain on a daily basis because I have my settings to shut the car down when I lock it up, including in the garage.
I have this gripe too. But 2.5 miles is about 500-600 wh. Multiply by 365 days and that is more like 200 kwh/yr. This was my biggest gripe. I could only see the spots when the windshield fogged up or evening sun hit it just right...even though I wiped the areas several times. Finally I just used some windex and they went away. Mike
We must be doing something different - I could park my PiP for several days and never vampire drain. Agree, no active cooling system on the PiP or all the things to cause vampire drain, but those are my experiences and those of others I have found to this point, What do you recommend to do this? I have sentry mode off, trying overheat protection off, not waking the car, what else? Quite right. I didn’t complete the math right on that one. I should have said 900+ miles lost, not kWh. About how many miles/day do you lose and have you found anything to substantially help?
All batteries self-discharge. Technically, it may not be counted as vampire drain, but the end result is the same. Age and climate influence it, so it may not be noticeable for all. Assuming the 3 is like the S, there is also a 12-volt protection system in which the car periodically connects the traction pack to charge up the 12-volt. So the vampire losses are the accessories plus the self discharge of both batteries. Came across a post from an owner of a S and Leaf, which doesn't self-charge the 12-volt while off, that experimented with leaving the cars unplugged. The S lost range after the one or two weeks. The Leaf didn't have note worthy range loss, but needed a jump to start.
I'm losing about as much as you, give or take. One thing I found, by accident, is that my phone was losing charge overnight, excessively. It turns out that when the phone Bluetooth is on it tends to drain its battery faster. Specifically if your phone is right at the edge of its range to the car considering the obstacles. Where I normally put my phone at night I saw my phone battery drain at least 5x as fast. But if my car was further away (in driveway instead of in the garage) this didn't happen. There has to be some similar effect in the car. Mike
To be fair, when you start with such a short range, the miles lost to vampire drain can be written off as a rounding error.
that would be true if the battery were connected. but only the 12v is subject to vampire drain, and after 9 weeks, my 12v only drops a couple tenths. and that without shutting off sks. now self discharge on the hybrid battery could probably be a rounding error. but i don't leave any wall charge when i'm gone, and it shows the same number of bars when i return. i suppose i would need a scan gauge.
I can attest that the range achieved in our former PiP matched the unchanged guess-o-meter after several days unplugged. We have left the vehicle unplugged at home and at the airport on vacation for ~1 week several times in the past. The Model 3 is a better car for us in almost every way. Just pointing out something they can work on in the future to minimize these excessive vampire losses.
to me, vampire losses are unknowns. tesla, and everyone else should have a handle on the specific drains.
Hard to know everything. But some things need to be understood . Or maybe a bit better would be the operative way.
possibly a listing in the o/m would be helpful, so owners can choose, as o/p and others have discussed above. still waiting for reply from 'others' though. maybe i'm missing something.
Yeah knowledge is power in certain circumstances . If you know what certain draws are and what they equate to, you can at least be an educated user rather than the experimental method.
lite bulb! genius 42" console screen has a option telling you what is turned on and how much it is drawing! does anyone have elon's email?
Hard to have a connected car without some vampire drain. Also, if you are including the cabin overheat protection energy uses in this vampire drain, then yes, those are likely a huge percentage of that overall drain.
Certainly. This is mostly a win compared to the alternative. Still, it's hard to believe Tesla can't improve substantially on the 1% vampire loss a day. I suspect they will. On the Tesla forum I follow, the manual's attestation seems to be the norm: Since acquiring the vehicle, I have had cabin overheat protection on. Turning it off may help substantially. Some have reported that that mode uses a good amount of energy even if high temps are not experienced in the cabin. One guy just did an experiment with turning this off at the airport where he parked his car for 15 days and lost 8% state of charge during that time. That cut the loss almost in half. It's cooler here this week, so turned it off a couple days ago and we will see what happens.
