Explain battery drain and Snowflake

[Kryptek]

It may have been from a motion light in my yard constantly activating, setting off the sentry mode. Turned off tonight will see tomorrow!

MY CT and Y sit in the same garage, CT has blue snowflake, nothing on the Y. Garage temp around 40/45 degrees, outside around 20/25 degrees. I think what others are saying is true in that Tesla is providing the info as a caution for the time being with the new cells. Will have to leave it unplugged overnight and see what it loses in charge.

We installed a 24k BTU mini-split heat pump in our garage and had the attic filled with some blown-in cellulose insulation. Total cost for the heat pump + insulation was around $3k, granted everything was in ideal locations for a simple install. The walls were already minimally insulated...1" of exterior foam only. It keeps up even in the AZ summers. I bet you could hold 70F-74F year round with ease. Would highly recommend if it's an option for you. No more preconditioning and greatly improves comfort when working in there.

There's no battery/Phantom drain in that picture. The blue is battery that can't be used due to cold. It will increase the colder it gets and decrease as the battery is warmed.

The snowflake lasts until the battery is no longer too cold.

In 0 degree weather I've seen it last an entire 3 hour trip.

To add on…all of this information you are asking is located & “broken down “ in the manual in your touchscreen of “every Tesla”

Battery temp ranges aren’t in the manual, but you can see them in service mode. The snow flake seems to appear when the battery temps are somewhere in the range of 10-18deg C

I’ve recorded these on a few dozen recent trips, including one where it got down to about 4 degrees below freezing over night (the truck was outside).

As far as I can tell… When driving with the snowflake, the octovalve was usually in ambient source mode (pulling heat from the autopilot and drivetrain I think). When parked, it was either in ambient or series radiator bypass. The power train coolant pump was always on regardless of driving state, temperature, coolant pumps, anything it seemed, just always on. The chiller pump was on about 80% of the time, also regardless of whether the snowflake was displayed or not.

I am observing a 10 day test of drain in cold weather. So far drain is minimal. https://www.cybertruckownersclub.co...n-observation-data-sitting-in-the-cold.31915/

Same here…my drain is minimal as well. I’m sure it will improve with upcoming software updates as it always does

My apologies, I was referring to the original question of “what is the snow flake & explain battery drain”. I hit reply to the wrong one

Sentry is draining 2-3% every 8 hours here in FL and it's intentionally parked away from people and other moving cars. I'm on 2024.39 though... unsure which updated lowered drain.

It's been 0-15 degrees out by me for the past couple of weeks. My schedule varies from day to day, so I have simply started preconditioning the battery by scheduling it the day of, a half hour before I leave and that has made a difference. As compared to just preheating the cabin.

With an 80% charge I'm seeing 70% available so 12.5% unavailable(not loss).

Here's a comparison with the mpg loss during cold weather for two of my other vehicles:
- F-450 mpg drops from 14 to 10, 28.6% loss.
- Colorado drops from 21 to 16 mpg, 23.9% loss.

I assume you have read owners manual that explains these?????

The little green Lightning bolt in a circle there under the headlight indicator is showing there is reduced regenerative braking. You see it a lot when you have a snowflake.

You used to have much less braking when that symbol is on, but I haven't noticed that happening with my Cybertruck. The 2020 MY, yes. Cybertruck, no.

I appreciate your valuable input, forums are for discussions, beyond what a manual may say.

I did notice this as well.. Now I don't know if I'm wrong but I feel power is reduced as well. Almost feels like I'm riding in Comfort setting.

Like i said my cybertruck is sitting in a heated garage with my modely and on the app only cybertruck shows a snowflake. Never saw it on modely. Same garage different behavior.

I have several Teslas and some are in a heated garage, the snowflake is triggered by the weather network info for your area, and the blue bar will tell you the impact on the battery once it’s out and running in the cold. Having it in a heated garage makes getting it warm easier and helps with charging. My older model S doesn't have that, but the Y does.

Hi guys,


This is my 6th tesla.

I’ve had the cybertruck for a week and the snowflake always comes on no matter if I precondition it and store it in my heated garage. It’s a different battery and it will always have the snowflake when temperatures are cold.

on a sidenote, I am really enjoying the cybertruck!
