Best ways to prepare for a week in the heat?

[blakeypoo702]

Literally just ran this experiment today in Las Vegas with a high of 107 today as it’s the hottest day of the year by far. I’ve been leaving overheat protection off to conserve battery as my girl parks her model 3 in the garage and tops off overnight while I charge once or twice a week once I get around 20-30%. I leave sentry off as well so I get almost no phantom drain. When I checked this morning around 7am with an interior temp of 90 I was at 77% battery. I just checked right now at 6pm and am at 68% with the interior temp reading right at 100. So easily 10% gone on a hot day with just overheat protection enabled.

I've tried searching the forums, and mostly came up blank so let me know if you remember a good thread.

Basically, I'm going to go to Lake Powell in late August, and want to bring the CT. I'm worried about parking it in the heat for a week. I'm not really able to do any hot weather tests in San Diego so I'm hoping for some advice from my hot weather friends here.

1. Does anyone have experience with how much battery gets drained in 100+ degree heat per day (with Sentry off)?
2. How much does an external, whole-body cover (OEM or other) help?
3. How much does that AND covering inside of the windows with sunshades help?
4. Any tips for Page, AZ in general, other than pumping up to 100% in town before parking?
5. Has anyone else done this?

Hey, Scotty and Everybody;

I learned something yesterday and today.

I took my truck to the SC yesterday for a tire alignment. Before heading out I parked the truck in an uncovered lot in downtown Phoenix, and I turned off climate control, and sentry mode, and vented the windows.

After about 4.5 hours the truck had only dropped about 5 miles of range, as compared to the day prior (2 days ago) where it lost 12 miles but with climate control on.

But yesterday, without climate control, the camera in the front windshield reached 120 degrees. At this temperature it will automatically shut itself off (this is new information to me and what I learned today). All I could see on the screen was that “Autopark is Unavailable.” But FSD also would not engage.

So the Service Center had me remove my digital rearview mirror, because they wanted to say that the issue was caused by the rearview. They did not know anything about me turning off climate control on purpose to help with range testing/loss in extreme heat.

Long-story short: if you turn off climate control in extreme heat it can cause your camera to throw alerts that stymie FSD & Autopark. The camera enters self-protect mode at 120 degrees F and turns off.

It was not the digital rearview mirror doing anything. Connecting the power of the rearview mirror to the power supplied to the front camera did not cause this issue and I continue to have zero issues with wiring the mirror at this location short of the Service Center looking to blame the digital mirror for a native Tesla built-in fault protection that was caused by not having climate control on.

Now I need to re-install my rearview mirror because, well, someone took a shotgun approach to troubleshooting instead of using a scalpel and all information available to them. But it is all good! I now have more knowledge…. The front camera will shut down at 120 degrees F by entering self-preservation mode.

And get this: the Service Center is yet attempting to blame the rearview as noted in the attached screenshot by saying that it is blowing hot air at the camera housing. Physics be damned, it’s the fault of the rearview mirror!! lol!?

Honestly I’m just glad to get my vehicle back hopefully without additional problems. I only scheduled the tire alignment because other places do not align Teslas worth a damn.

Yeah…so again, my practice is cabin overheat protection on but at 100 degrees. By my testing this makes quite a difference without a cover but almost none consumption wise with a cover on.
I don’t know if that is true but there are lots of reasons to leave it on in my opinion.

It says 120 degrees Celsius in the notes. Which makes way more sense than Fahrenheit. I’m in Vegas and 120 is a normal summers day here lol I was like there’s no way otherwise my fsd would never work. I don’t use cabin overheat as it consumes 10% over 12 hours in the sun which is an insane waste of electricity.

Thanks for the updates guys!

Sounds like the external cover does the bulk of the work which makes sense, I’m thinking it’s a sure bet with inside and outside covers and sentry/cabin overheat off. We’ll see where the solar goes but although I’m not super concerned with vandalism/theft, leaving a couple thousand just sitting on the car might be a bit too enticing.

Yeah. That does make a lot more sense. That said, could that little black surrounded glass camera compartment sitting in direct sunlight in phoenix reach 20 degrees above the boiling point of water? Absolutely.
The ambient temp by itself is near 120F
