Keep cabin overheat protection on permanently

[UncertainTimes]

The car is plugged in but it’s still drawing energy from the battery. So you’re wasting battery cycles, aging the battery, aging the HVAC system, wasting money all to keep some electronics cool. Ever hear of a car cover or canopy? Parking under some trees?

Pretty sure if the car is plugged in and HVAC comes on, the car does not use the battery at all(but obviously takes/wastes energy from the source). I'd like to see the basis for your statement.

We’ll I dunno for sure. Read these and come up with your own conclusion

Does “shore power” go through the battery?

Can the car route “shore power” directly to accessories? (well not directly directly, but after AC to DC conversion. e.g. If you have 6 kW AC input power and then turn ~1 kW of accessories on (AC + high fan?) is the car (a) sending all 6 kW to the battery and taking 1 kW out of the battery, or...

Is power for climate supplied by batteries or charger when battery is 100%?

2022 RWD Model 3. If the Model 3 is sitting on 100% and still connected to a high-amperage AC charger, is power for climate and interior functions drawn from the connected supply or does it run off the battery and top this back up?

Only in our first-world greenwashed fantasy land would anyone seriously entertain keeping an unoccupied vehicle air conditioned for weeks at a time.

What a fantastically stupid and wasteful desire.

That's not helpful of you to assume it would be running the air conditioning. The newer cars have that ventilation fan only setting, which does not use all that much energy. That would be appreciated if that were available.

There is Zero logical reason to run the COP for weeks on end while the car is plugged in.
Why else would Tesla themselves put a 12hr. time limit on COP. It is ONLY designed for short time use, in case someone accidentally left a child or pet in the vehicle.

It's also not bringing the temp up or down to 72 degrees. It's just keeping it from being lethal.

And how many people turn off their home aircon and water heater when they go on vacation? Those devices even have built in options for those occasions. We should be hitting the master breaker when we are away.

I also am looking for a solution to this. Sorry if I offend any who live in Alaska but here in Florida the car gets excessively hot. I don't drive it every morning to auto reset the COP. Like just now I forgot to reset it and just checked and the temperature is 148°F. There is some glue dripping onto the floor from under the dash and seat back. Very sticky and hard to clean off the carpet and floor mats.

My normal solution is to just unlock the car from my watch app and then lock it up in the morning. So while I've been typing it is now down to 104.

I've tested the battery drain and it is not that bad. The AC or pet mode is not on a timer but that consumes much more even at the highest setting.

Some have suggested TeslaFi which I have so I'll see if I can find a way to automate it.

How many kWh per day are we talking about? Just don't park your car in the sun!!

On the hottest Arkansas days this year my car dropped 8% in 9 hours. I'd like to park in the parking garage but I'm about 8 months out for getting a spot, but every time I check it's further into the future.

This isn't about keeping the car "air conditioned" down to a person-comfortable temperature, it's about utilizing the cars ability to keep itself from getting crazy-hot inside and causing damage (extensive interior heat will prematurely age interior components). The temperature that this seems to get enacted is about 100 degrees Fahrenheit, 40 degrees Celsius. Yes, it uses energy (and how much energy depends on factors such as whether the car is in direct sunlight and the outside temperature), but to me is a good investment to protect a vehicle I hope to have for several more years.

When I reset Cabin Overheat Protection in the morning the car never goes above 105° which is spec according to Tesla. At 105 the fans come on and circulate the outside air to cool it down to 100° when the outside air temperature is the same. On cooler days the fans shut off about 96° when the outside temp is in the high 80's. On an average day I lose about 1-2% battery when the COP is very active. However, Elon Musk has recommended keeping the cars plugged in when parked at home and setting the charge current low. I found 12A to be ideal. Also, this EVSE at 120v 12A doesn't run 24-7 either. Instead that comes on when the battery drops 5-6% SOC and then replenishes and then shuts off. The consumption data for model Y and S is very similar. We use the Tesla Wall charger at 27A for overnight charging as that car is used every day for about 140 miles. There is no way to plug that in during the day.

So all the chatter about wasting valuable electricity is just nonsense. More important for me to protect my investment from excessive heat damage even if I have to pay $1.30 a week for electricity for COP.

I didn't see an easy way in TeslaFi to set a timer on COP.

There is absolutely, positively no recommendation from tesla, or elon anywhere that says "setting the charge current low".

Hi,
There is no glue in the 3 or Y seat backs. The seat backs are held on by the headrests. Just pull the headrest up and the back of the seat falls off. Then you can clean whatever you got in there. There shouldn't be any glue. The seats are all foam, plastic clips, fabric. The whole seat comes apart fairly easily. I was looking at getting leather seats at one point.

You could construct something like this that won't run off the Tesla battery and MCU?

Wait, watch app? There is a tesla watch app for the car? Sorry, off topic.

The more you cycle the A/C compressor, the chances of a failure increase. Using cabin overheat protection all the time will likely lead to premature replacement of the compressor. Cars are designed to bake in the sun. Use a windshield screen.

Only 3rd party ones sadly- another weird tech oversight on Teslas part

Please post the link to your proof of excessive heat damage.

Every car on the planet gets hot when the ac is not running. Tesla is just a company that tells you what the temperature is.

Haven’t you seen all the jokes of people baking cookies in their car in Arizona?

Hey, hey! Baking cookies in your car in Arizona is no joke. It's a way of life!

 

[SSonnentag]

Environments don't get much more hostile than here in the Arizona desert. Cabin overheat protection uses around 15 kWh during a 10-hour work day. So I'd guess somewhere in the neighborhood of 20-25 kWh maximum power use for a full day's use. That's enough power to run an average home for an entire day in more hospitable climates.

One legitimate use I've found for COP is that it keeps the 12V outlet alive so that my in-car refrigerator (Dometic) will stay running while taking a road trip and parking for several hours, supercharging or staying overnight in a hotel.
