How Much Does Cabin Overheat Protection Impact Tesla Model 3 Range?


Parking your Tesla Model 3 out in the hot sun for hours? How much range will you lose?

Tesla recently added Cabin Overheat Protection to its Model 3. It assures that if the interior temperature of the Tesla Model 3, Model S, or Model X reaches an unsafe point, the feature will engage and cool it off. This happens when the car is parked in a warm area or in direct sunlight, etc. YouTuber Alex Venz left his Model 3 parked outside in the heat during his entire eight-hour workday to assess the range loss related to the feature.

Obviously, everyone’s situation is different. This is not scientific data and Alex admits that. The temperature and amount of time the car is parked come into play, as well as how much direct sunlight is reaching the Model 3, whether or not the car was accessing any other features, and the list goes on and on. Still, it’s nice to have a reasonable picture of what level of battery drain this type of feature might impose.

For reference, Alex says he loses about three rated miles per day if the car is simply idle and parked in his garage. His garage doesn’t get hot enough to initiate Cabin Overheat Protection. During the eight-hour time period in the hot sun, his Model 3 loses about 12 rated miles.

Do you own a Tesla? How has this feature impacted your range? Let us know in the comment section below.

Model 3 Cabin Overheat Protection: Range Impact?

A less than scientific look at how much energy the Tesla Model 3’s cabin overheat protection feature uses when parked outside over the course of a warm 8 hour work day. Observations were made with software v8.1 (2018.36.2), results with other software versions may vary.

Quick videos like this are what happens when more complex video projects aren’t going as planned… Then again, I don’t think I’ve really ever paid much attention to how much energy cabin overheat protection uses in my Model S.

I normally lose 2-3 miles a day to vampire losses. I haven’t had the overheat protection come on since I park in garages at home and at work.

Could leave it on in case you ever do and forget to reset it though.

On the hot days over 108 I was losing anywhere from 10-20 miles on average per 8 hours.

what is the overheat protection supposed to protect against?


Or rather…


Children or dogs dying in a car left unattended.

Is it ok to leave kids unattended inside cars?!
It wouldn’t be better to activate the function just when there’s movement detected inside?!

It’s not ok, obviously, but people do it all the time. What about children sleeping. An 18 month old in a car seat isn’t moving around much.

Leaving small kids (<6) unattended is a criminal offense here; I think some US jurisdictions are the same. We get several deaths a year due to people forgetting small kids in the backseat.

Some of us would rather not bake the car’s interior if it can be avoided for minimal cost.

Destroying the screen. There are videos showing the bands of glue “dripping” from the screen.

So, it might be to protect life….but it’s likely it’s also to protect the life of the center screen.

Nothing better than a car that is not blazing hot on a 120 degree day! Love it! Should help protect the interior of the car and definitely seems worth the cost to me.

They put a non automotive grade screen in a car?

Steven, this piece from a while ago was really interesting but it would be great if it explained how a circuit could reduce miles of wires to mere meters. (do you have a twitter handle?)

per the below, I mean to include this link —

So, it is only couple kWh. That is pretty good. I guess it only needs to bring the car down to “safe” temperature. I wonder how much is done with venting and how much is actually down with AC compressor.

You can select venting only or A/C as cooling. Venting isn’t going to do much if the temperature outside is above 95 degrees F or so. But venting would be sufficient on cooler days.

“Cabin Overheat Protection” also exacts an energy toll because the car will not go to sleep during periods it is active. So the true cost of running the A/C for Overheat Protection may be lower, but the car will not shut down other energy intensive services during COP use.

Can this feature be turned on/off?
What if you are on a business trip and you car is parked in the sun during the summer in Arizona for a couple weeks?
Somebody mentioned you have A/C option or just fan, how will these option affect the batteries over a two week period?
To me it sounds like a condition you want to be able to disable it all together, but what affect will the heat have on the batteries?

So many questions and unknown answers.
I’m considering purchasing a Tesla, but don’t own one yet.

Yes it can be turned off

Why not just crack windows open a little bit? I am surprised Tesla does not have that feature especially on the X. I see 110F+ during a sunny 90F day and that is with white seats. Blower would be enough so no AC needed.

Still totally confused why this is needed. Don’t leave pets/children in the car unattended… period!!!. Ok that behind us…why do you need this. The car better not have issues from being in the sun or I would say, what the heck… Beyond that, I can easily turn the AC on with my phone shortly before heading to the car to drive. So, again… WHY is this a feature?

It’s a safety and convenience feature. Some people are ignorant and unaware and children and pets have died. In some areas, it’s incredibly hot and people would rather not get into a steaming car at the end of the day. It’s not necessary for everyone, but neither are many new car features. Automakers are constantly adding new safety and convenience features on a regular basis. Whether or not every person wants them or needs them makes no difference, there will still continue to be new features that are helpful to many.

My elderly dog loves to come driving with me everywhere. He waits at the door for me to take him in the morning and is happy as a clam sleeping in the car while I attend to daily business. I manually set the “away” function on the HVAC whenever I leave him so he’s comfortably warm or cool as needed.

If, god forbid, I forgot to to set it, I’m sure he would appreciate the failsafe feature.

This is needed if you live in hot climate. Here in Texas my car is parked in sun for 8-9 hour everyday. The temperature inside the car shoots above 140F. Takes forever to cool down if you forget to precondition it.

Maybe its also good for the battery module.

Why need the feature? Likely a marketing gimmick / spin on a necessary feature ie the screen. Here is why I want my interior cabin always conditioned to a nominal temperature – Less energy is required to maintain a comfortable temperature. That is right just like your house, your system does not turn off and let the house bake all day from the sun load warming the interior and all of the materials inside. Less energy to pull down the house once and maintain a comfortable temperature.
