If it having the car plugged in stresses you out ... just don't do it.

I put my cell phone on a (wireless) charger whenever I am near one. I have a wireless charger at work, on my desk at home, on my night stand, and in one of my cars. I only charge the phone up to 80% unless I need more stored power for a specific activity. I probably do about 2 cycles a day on this phone. It's the same rules you follow with all li-ion batteries: do not charge to 100% and smaller depth of discharge is better than larger depth of discharge. You know how cell phone batteries typically start to degrade quickly? Well after almost 3 years, my battery is still at 90% SoH.People tend to plug their cell phones in when they get pretty low... nobody charges at 85% (with only 15% down from full).
Why? Many people have to charge outdoors, and it's not just Ys. My daughter charges her X outside. Doesn't seem to have ever hurt it or reduced her range. As I happen to have a garage that's not full of junk, I park my S and my 3 in the garage and plug in whenever. It makes no difference to the car if there's a roof over it or not, because the charger plug is waterproof. The main thing is to keep the car charged so it will be ready when you need it. If you constantly keep running out of range, well, that's why I paid extra for an S. Where I charge it makes absolutely zero difference.I know the Tesla charger is rated for outdoor use, but does anyone not keep their Y plugged in because it's outdoors?
if you charge outside and are on vacation, then leave it plugged in and be sure to turn on Sentry Mode
When Sentry mode is active the Tesla Model Y remains powered on. Power consumption while parked is 230W continuous. The Tesla Model Y will top up the battery as needed once the state of charge drops a few percent. This will maintain the battery at the set charging limit. (When the Tesla vehicle is allowed to enter sleep mode the power consumption is 25W (about 9X less) than when the Tesla is powered on.)This won't run directly off AC though, right? Doing this would likely cost a full HV battery cycle each week'ish.
While parked the Tesla vehicle will not use energy from the grid or from the battery to cool or heat the battery unless this is required for charging or when preconditioning.It was my impression that by leaving it plugged in the charger also maintains proper cooling and heating for the battery pack as well as keeping it charged to the Optimum level for your needs.
It's a nice safety feature for the battery that wouldn't happen if it wasn't plugged in. Not even sure why this is a debate. Tesla has said many times that the best way to take care of the battery is to leave it plugged when not in use. It is also recommend to keep the battery charged to the minimum past 50% that you need for your daily driving and to set the charger at 30 Amps instead of 40. Seems to be working well for me so far. Almost no degradation in 9 years.The Tesla vehicle will not use energy from the grid or from the battery to cool or heat the battery unless this is required for charging or when preconditioning.
Once the battery reaches the preset charging limit the Tesla vehicle stops charging, stops using power from the grid. Whether plugged in or not plugged in once charging has been completed the Tesla vehicle does not cool or heat the battery while the Tesla vehicle is parked because this would just waste energy.It's a nice safety feature for the battery that wouldn't happen if it wasn't plugged in.

This impression is wrong.It was my impression that by leaving it plugged in the charger also maintains proper cooling and heating for the battery pack
It’s a debate because what you are saying is flatly wrong. The car will condition the battery as necessary, at any time, regardless of if it’s plugged in or not. Nor is there any recommendation to charge at 30 amps vs. 40. This “recommendation” is imaginary.It's a nice safety feature for the battery that wouldn't happen if it wasn't plugged in.

It's an intentional programming choice to make that tradeoff. It won't do as much active heating or cooling while unplugged, because that could deplete people's range, and make for unhappy customers. But if the extra energy is available externally, they decided to do what is a bit better for the battery by moderating the temperature range.the Tesla vehicle does not cool or heat the battery while the Tesla vehicle is parked because this would just waste energy.
I would be interested in seeing the data, especially as regards warming the battery when plugged in with cold temperatures.No, this is not true, which had been observed directly from the car's own data years ago. When reading values from the car with one of those 3rd party tools, like maybe Scan My Tesla, you can see the values the car is using for its high and low temperature range targets. The car will use different temperature targets if it detects it is plugged in, versus if it is not.
So the way this behavior looks like in real life is that if the car has been parked all day out in the sun at work during the Summer, and it has been getting toasty on the hot blacktop at over 100 degrees, and you then drive home just a few miles, you pull into your garage. The car may just quietly sit there when you park, because the allowed temperature target is that high. But then if you plug it in, the car is set to know that it has extra energy available and won't be just using up your range, so it moves the target temperature down, and it will start drawing from the wall connection and will activate the chiller and start actively cooling the battery down to get it into a more ideal temperature. This has been measured and observed by multiple people. I guess it's just not widely known. And again, this was seen on the S and X platform. I don't think I have heard if the 3 and Y do things differently. But if so, then don't generalize about "Tesla vehicles".
