Going on vacation. Should I leave it plugged in?

[Misterbee]

It literally does. I can't see anything you are asking for that it doesn't already do. It can be set at 50% for ideal long term storage level, and it will give you every single status change update of every charging session, as you are asking for. What else is there?

It's not a "battle", and I am really not trying to do anything bad to you at all or trying to "win" something. You just seem to be asking for something that already exists exactly the way you want, so I can't figure out what you are dissatisfied with.

I think he wanted the car to set the optimal SoC on it’s own.

Hi all,
We are planning to be away (flying, not driving) for a week. Should we leave our Model Y plugged in while we’re gone? Is this necessary? Or just let it sit in the driveway?
Thanks!

Noooooooooooo don't do it. You will only be gone for a week. At most you will only lose 8 miles per day.

This thread is 6 months old, just saying. The Op has probably taken more than one trip by now.

Not sure why there is debate over the question. There is zero downside to leaving a Tesla plugged in. True, I don't think a Tesla would disintegrate if left unplugged for a few weeks, but then, what's the advantage of leaving the machine unplugged?

We don't all have garages - I park in the City on the street, usually right in front of my house, but can't leave it plugged in wo a cover over the cord across the sidewalk - Id like to get it charged to 70-80% then leave it in between trips, usually only once a week.

Then your options are as you described them (it). Just leave sentry mode off, don't check on the status of the vehicle with your app (wakes it up) and at the charge level you suggest leaving the Tesla of 70-80% a couple of weeks should not be an issue.

You could get a monthly contract in a parking garage where you might even be able to charge the Tesla vehicle.

Good idea except for the cost in urban areas. Buddy of mine (who owned an ICE vehicle) kept his car in an indoor garage in Manhattan. Cost as much per month as an apartment would have run in many other parts of the country! Understand, in NYC, a car parked on a city street is considered as nothing more than spare parts free for the taking...

this is very basic and well known to the old time Tesla owners.
set at 50% state of charge. keep plugged in.

Why 50% rather than leaving it at the 80% setting I now have it set at?

Battery longevity is maximized at 50 percent state of charge.

How much battery level drops if the car IS NOT plugged in but has sentry mode on?

How much battery level drops if the car IS NOT plugged in but has sentry mode on?

6 to 7 percent, per day, down to 20% when the Tesla vehicle will turn off Sentry mode to conserve the remaining battery charge.

Ok…thank you for the info.

Old thread, but I was wondering how you leave the car plugged in, I.e., with scheduled charging? I have scheduled charging for a departure of 6:30am each day. Should I turn this off and set it differently? Will be away for over a week.

I would turn off the departure timer if it also preconditions. No sense wasting electricity when you aren't home. For a week, I wouldn't even plug the car in, but that's just me. Set it at 60% and forget about it.

Scheduled charge setting won’t matter either way. If it’s at the limit (or within 1-2% or so) it won’t try to charge. Or just turn it off.

As the other comment mentioned, just be sure to at least turn off departure preconditioning so it doesn’t waste power heating/cooling the cabin.

If you can plugged-in in a safe location then just leave it plugged in. If not, then turn off sentry/cabin temperature protection/preconditioning and leave it off. I have experience in both, plugged for few weeks and also leave it off for 5 weeks (lost around 25-30% or so), just make sure you don't constantly checking it in the app to prevent it from going to sleep.

3/Y should lose less than ten percent over the course of a month. Big improvement compared to first gen S/X.

I just came back from a 2 week trip with my MY unplugged in my garage with sentry turned off and it only went down 2%. Quite happy with that.

I have no doubt 3/Y is more efficient but also have a bigger battery. I lost around slight more than a mile a day or so standing still.

I agree...the Owner’s Manual couldn’t be more clear:

“About the Battery

Model Y has one of the most sophisticated battery systems in the world.

The most important way to preserve the Battery is to LEAVE YOUR VEHICLE PLUGGED IN when you are not using it. This is particularly important if you are not planning to drive Model Y for several weeks. When plugged in, Model Y wakes up when needed to automatically maintain a charge level that maximizes the lifetime of the Battery.”

If plugged in unattended, how may it handle any potential power surges, lightning, etc.?
