Again, you don't seem to understand the nature of facts. The fact that your personal experience (at limited low temperatures) was positive does not say anything about what will happen at lower temps for other cars at other locations. Why do you not understand this important issue?

That's called "anecdotal" and is not a good basis for establishing facts.

So the only point you dispute is the temperature where a continuous charging connection is required? Where do you find info that says the car will not heat the battery if not plugged in? I'd like to read the entire text. A google search on that text did not find anything useful. The theft...

In one of the threads a person posted a data display from his car that showed the heating threshold was just below 20 degrees F. He said the value can range between -20F and 20F "depending" on factors he did not list. Level 1 and level 2 EVSE have little to do with safety. The charger is in...

Already contacted the airport I'm currently using. They replied by telling me about the level 2 and 3 chargers they've installed with government grants. Oh well.

Actually, this thread is about providing inexpensive level 1 charging at places like airports where EVs park for weeks. Does anyone have ideas on how to get airports to provide such charging facilities?

I'm not "demanding" anything. I'm saying there is no point in talking about generalities since that won't help when my car is bricked. If you are unhappy with the conversation, please do not participate. I think you are being a bit pedantic. I especially like that you cite manufacturing...

Yes, well, people say lots of stuff. I'm looking for the information to support such a claim. I believe I saw someone post that the battery self heating comes on somewhere between -20F and 20F. 20F is pretty common around here. I have no reason to think the car can protect the battery by...

I carry a sweater on the plane. I still freeze at one end and can't stand having it touching me on the other. :o

When it gets to -40 you can drop the C or F.

I'm in a region where it won't reach 20 °F unless I'm in a walk in freezer, but the car is in Maryland. 20 °F is exactly the sort of very cold night I'm concerned about. I've seen half a week of such temperatures. My heating bill got to $60 a night. Any idea how much energy it would take...

So you live in a world where "It's potentially detrimental" is different from bad? Do you live in Washington, DC? Where I live we consider "detrimental" to be bad. Then you use "insignificant". In my world, if it's insignificant, it wouldn't even be discussed except to say, "pffft, it's...

I've never seen anyone distinguish between the two losses of battery charge. From what I know about lithium cells in general, there is very, very little loss of charge if nothing is connected to them. So there is at least one if not two orders of magnitude difference between what YOU call...

Yes, I'm trying to make sure I CAN drive when I return from the tropics to a frozen metro area.

Wow! So the suggestion that it's ok to charge to 90% is bad and leaving it plugged every day is bad and of course the combination of the two is bad. So we need to not listen to Tesla about the care and feeding of our cars? How about Tesla gives us useful info rather than sound bites? Tell...

I don't check on it. When I land I check the car to see if I need to do anything before I leave the terminal. That's it. Meanwhile, no one seems to know any details on what temperature the battery heating kicks in. Or did I miss that? It's not something that's easy to search on in Google...

Ok, you can make up any silly rational you wish. So the drain is 1% of the battery per day no matter what size battery? So the vampire drain is proportional to the size of the battery and does not relate to the electronic that remain on? You don't understand anything I'm saying. I have...

I've been watching my vampire drain very carefully and it varies more than I would expect. Sometimes it is about a half kWh per day, other times it is a full kWh per day. I don't change the settings. Sentry mode is off. Cabin overheat protection is off (that was running some 4-5 kWh per...

That may be your experience, but it absolutely is not mine. When the temperatures are warm I see between 0.5 and 1 kWh vampire drain per day. Still, this says nothing about what happens when it is very cold. I was stranded once when the car dropped abruptly to zero charge while parked for a...

I'm going to be parking at the airport for a week or two at a time and I have the same concern now that the weather is turning cold. The last thing I need is to arrive at 11 pm to a dead battery on a Tesla where the entire car has to be towed to a charger IF the 12 volt battery is not also dead...

Losing visibility could mean the car doesn't have a cell signal. Believe it or not, cell signals are not universal even in densely populated areas. It's also the sort of thing that can change as objects in the vicinity are moved like trucks or cars.

Yeah, this is what I was thinking of and I have the same concern of theft. I think simply cameras could deter the theft issue. You don't hear about cars being broken into in airport parking lots... right? I would think it would be the same level of concern. Speaking of which, when I was...

Wait... you only lost 2% over the entire 3 weeks? You mean you lost 1-2% per DAY over the 3 weeks or as high as 42%, right?

So the car will never use more than 1% (of something, what exactly is the 1% of?) no matter what the conditions are? That's not accurate. The great thing about Musk is you can find where he has said so many things. He is the one who said it's fine to charge to 100% sometimes. My point is...

How does plugging in the car impact battery longevity? If anything that's good for longevity. Leaving it plugged in does not mean it has to charge above any set value like most PCs and cell phones do.

You are confusing the voltage with state of charge. The two are very different things which is why it is difficult to determine state of charge from the voltage. Instead they measure the current and integrate that to measure the amount of charge remaining in the battery. To get energy they...

I'm not sure you understand the curve. It is a curve of voltage for what is assumed to be a constant load but is more often a fixed resistance which only provides a constant load when the voltage is constant. In any event, as you say yourself, the steeper curve allows more precision in...

That might seem to make sense superficially, such as going from 50% to 45%. But give it a bit of thought and explain how it can go from 5% to 0%! The cold would reduce the available range proportionally to the amount left. Dropping 100% is pretty hard to imagine. Even so, that is part of the...

You live in an ideal world where you plan every moment of your day I suppose. I don't need to stand in freezing rain to fill a gas tank. It's not much more than connecting the cable for my Tesla. I would connect the hose and swipe the credit card and get back in my truck. I'd get out again...

I have a regular trip to the airport with a 2 to 3 hour drive. Given the unpredictability and the length of the drive I may or may not end up with the time to charge before parking. Just this week I was routed at the last minute 20 miles out of my way because of congestion and had to stop at a...

Reading another thread I realized the issue with the airport can be summed up by, "Better is the enemy of good" - Voltaire

Why are you not rushing to avoid the idle fees? You still have a time limit, no? With a supercharger being ready in 30-50 minutes depending on the details and the urban charger taking an additional 10-15 minutes depending on details, I don't see how it relieves anyone of having a deadline to...

Yeah, I was caught by sentry mode once and have it turned off now. I also got caught by the overheat protection and that's now off. Too bad these can't be controlled via the app. Well, I know the overheat can't be, not sure about sentry mode. I watched my car drop many percent a day until it...

I don't know why the car uses the juice it does, but I once parked at a supermarket for an hour and a half on my way to a supercharger and the battery dropped 5% (~5kWh)! Clearly there are times when the car sucks power. There are recommendations to keep the car plugged in at all times, no?

I'm traveling a lot now and leave my X at the airport long term parking for nearly a week at a time. With the weather getting colder in the mid-Atlantic I'm wondering if I'm going to need to plug into level 1 power for times when the temps go well below freezing. My understanding is the car...

Just to make a note, when you share a charger, the first to connect gets whatever it requires. The second gets what is left over with the divisions in blocks of 36 kW I think. As the first car's rate drops the second car's rate picks up. The second car will always get at least 36 kW, so I...

l like the way the press is blamed for something that hasn't even happened yet. If you are planning a trip way in advance, you can check the current status of the chargers at the time of day and day of week you expect to be there. There aren't very many always busy chargers. Each has it's ebb...
