Winter efficiency

[trentsize]

I realize it’s almost July, but does anyone have some efficiency numbers from early deliveries this past winter? Preferably slower average speeds below 60mph, and legitimate northern states cold.

Our Model 3 LR kept ~85% this winter in West Yellowstone, Montana (garaged). Hopefully the CT can maintain similar, especially with software improvements between now and then.

I’m interested in the winter battery drain when not plugged in.

You can expect similar to your Model 3.
If you are garaged, it's not going to be a big deal, but if you have a regular daily commute, setting the departure time will probably warm the battery up a little more and increase your range.

The folks in Canada indicate that when they are using the departure time setting, their winter drop is not much at all.

It's best to leave it plugged in.

The battery drain in the winter is the same as the summer when not plugged or being used.

But a battery at 70 degrees dropped to 0 degrees has significantly less range.
But warm it back up and it has just as much.

As I mentioned, if you can use departure time, the power to warm the battery can come from AC. If you don't do this than that power has to come from the battery.

My “commute” would be 120-150 miles a day in Yellowstone, without a garage overnight, when it’s possibly below 0F, which is why I ask. I should be able to plug into 120v overnight, after charging DC to fill most of the charge in evening.

120V 15A may be iffy, anything better than that would definitely be desirable.
I'm just repeating what some of the Canadians on other forums have indicated.
If the vehicle is plugged into 120V 15A, then you'll be getting about 2 mph charging, UNTIL it starts conditioning the battery.

Aside from a much larger plug, little things like 120V 20A or 240V 15A would definitely help.
I'm not sure if you are at home or a commercial facility, (apartment, condo, etc). At commercial facilities, the 120V plug is often a 20A one, it can be seen by one of the blades being able to be vertical or horizontal.
If at home, if you only have a single plug on a circuit, or can disable the circuit, an electrician can switch it to 240V with no wiring replacements, just a new breaker in the panel.

It really comes down to not yet enough experience in really cold environments from a lot of people with the Cybertruck, which requires 50% more power than the cars.

I use 240v 30A at home, as well as the 120/20 plug occasionally. My winter trips are away from home. There are a few J1772 plugs in the town I can use (free), just not right at the hotel. I have not found a 120/20 plug at a hotel yet.
