Eliminate the blue snowflake ❄️

[Kryptek]

Temps got your charging slow or range lost due to cold!?

a cheap remedy is a propane heater like Mr Buddy.

I hooked up my tank to the 4k btu low mode and went from 21f to 56 last night and 27 to 67 this evening

1-hour run time no insulation garage. This allowed me to charge past 67% to 80% the blue bar was restricting charge limit.

I heard about a guy that put a heater directly under the battery pack.

It didn’t turn out well ?

I just put this in my 3 car garage with 12ft ceiling - keeps temp around 55 on mid setting. Outside temp from 15 to 35.

Had it about a week so far, doing good, no snowflakes.

Not me ?

Temps climbing ?

what type of cost are you estimating daily/weekly

 

[devdrone6]

Not sure on cost exactly, it doesn’t run constantly so right now hard to estimate.

But lets say 12hrs every day :

240v X 16amps = 3.8kwh
Times 12 hrs = 46kwh
Times my cost of 10 cents per kwh and so around 5 dollars a day. Mainly used for lets say 90 days out of the year, so around 450 dollars for the winter?

Might have to get a killawatt to measure exact usage.

It's 27F this morning. I just set supercharger as destination about an hour early and let it precondition for 30 minutes or so, then plug it back in and top it back off with heat on, no more snowflake. Probably wastes more $ than just driving but saves range anxiety when I have a longer morning trip into the middle of nowhere than usual. If I had a garage I'd definitely do the heater on a timer thing...

We are rehabbing our shack and moved into another shack for the MN winter.

Rental shack has a one car uninsulated garage. And we are charging with 120V as shack isn't set uo for EVs.

There is a huge difference in charge times for inside garage vs outside once temp get below 20 ish.

Luckily we do not drive much and are at home most of the day so cars trickle charge just enough for us to get by.

this is a simple fix, put your Cybertruck in the garage, plug it in, roll down your windows, turn on your defroster and precondition the batteries, from your app, the windows will stay down, it will warm the garage over 60 degrees, forget about propane, eliminates the blue snowflake asap, and increases charging.

Also, send service messages to Tesla via the app. This hasn't been a problem with either of my 3's, so something needs tweaking with the preconditioning software. The more people ping Tesla on this, the better chance it will be addressed in an update. Remember, they are really the only ones who can actually fix the root cause of this problem.

The CT is more sensitive to temperature than other Teslas. Some slight chemistry changes means the cells don't like cold temps as much. Rule of thumb (but not 100%) increasing nickel while decreasing cobalt increases energy density, but narrows preferred operating temperature. Given that the CT is pushing 90% nickel (IIRC 88%) and running 955 (ish) chemistry, it'll be a lot more sensitive to temps than the 2170s running 811 chemistry. Then the 4680s don't tend to create as much heat discharging so it takes them a bit longer to get up to temp. In my experience so far, driving for a half hour or so raises the pack temperature enough to get rid of the snowflake. That's with temps in the 20s and 30s (and truck is garaged with no heat in garage, but insulated). My 3 would be after 15 or so minutes.

Basically, don't expect this to actually change. Maybe Tesla takes the snowflake away to keep complaints down or changes the thresholds, but you can't change physics. A cold battery is still a cold battery.

Yeah, but if I have it plugged in to my 11kw wall charger all day, and I have scheduled departure set, then when that time comes, it should be fully preconditioned at that time.

Heat-pump-octovalve warmth into the batteries at 11kw for 6 hours for all I care, just get it preconditioned at the percent I've set it to, on time (@Tesla).

The battery will be at the percent you set (with some BMS sway), but a few percent will be decreased for the cold battery. Even at 50% and it said like 44% available. By the time you drove that 44% the battery would be warmed up enough to utilize that extra 6% (and some because of a buffer below zero). If you want it to say __% just set it 4-5% above.

Do you have a guess on the run cost.
