I'm on a time of use electric plan at home. My teslas are scheduled to finish charging by 5 am when super offpeak pricing ends. If i want to run the kids to school at 8 AM in the winter i want to defrost my car a few minutes before we leave, but when i do the car starts charging again. My electricity is expensive at 7:50 AM. Is there any way to defrost without drawing power from the grid without walking outside and unplugging?

Defrost without charging?

I've never had to defrost because I live in SE FL and do not road trip in the winter, but I am curious if the defrost won't still work when the car is not plugged in?

It will pull from house power to precondition whenever it’s plugged in, even if the battery is at your charge limit. Only way to not pull from house power is unplug it.

And is us just a few minutes, it’s probably going to use less than 1 kWh even at max defrost. That’s like what 50 cents or less even with high electric rates?
I know people in Sweden using net service that limit charging to the off peak time.
This means that even connected, there is no electricity to draw from the wall connector oitside off peak / cheap electricity time (or equivalent ”chargers”, probably need a charger /commector that supports this principle).
I do not use that myself, I use a flat rate so I have no details that work outside Sweden or EU

Great suggestion! I had looked at all the settings for the cars but not for the charger. Let's see if this works!.

Yes, just about 50 cents a day to defrost. That's quite a bit when i'm only paying about $30 a month to charge at night.
Success! I was away on business so I couldn't test this until this morning. I defrosted my Tesla Model 3, while it was plugged in, without drawing any power from the grid. Thank you all for the suggestions.
I believe you can also set up the Wall Connector to not deliver any power unless it matches the VIN number(s) entered into the Wall Connector? Switching the VIN number back and forth would be more of a pain but it might be useful in some strange use-case.
