Model 3 SR Plus Impressions

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.

hybrid battery is disconnected on pip, no drain at all in 9 weeks of sitting.

 

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.

 

yes, not noticeable. and certainly not 2 miles a day.

 

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.

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.

 

to me, vampire losses are unknowns. tesla, and everyone else should have a handle on the specific drains.

 

“Should” is the key word.

Do they ?

 

apparently not

 

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?

 

No email but you can find him easily enough.

 

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.
