Precondition weak on battery prep

[Rhineg]

2024 Cybertruck - when I precondition our Cybertruck the cabin temperature achieves desired setting by scheduled time BUT the battery still shows the snowflake at that time. Any hints? Do I need to schedule before desired departure... by how much when outside is 10 to 30F?

It should be properly preconditioned by the time you have set it to be such. If it's not, then something seems amiss. I just did a week in same temperature range and when I scheduled it say at 8am, at 8am the battery was properly preconditioned and cabin temp as well. Perhaps schedule 10 to 15 minutes prior to when you really were planning on departure and see if that helps? If not, you might want to touch base with service...

Service? The batteries take longer to warm up than the cabin. Depending on the cold, they can take a very long time. People have reported over an hour for the snowflake to go away.

It's not a service issue with the truck, it's just the thermal management of the batteries.

You've missed the point. He scheduled the precondition to be completed by the time of departure. It wasn't ready as it should have been. It knows how cold the pack is and should be able to compute the time required to precondition in the range of temps he was experiencing. Otherwise, what is the point of preconditioning? It simply didn't do it in temp range that it should have easily. Something is amiss or perhaps the possibility of user error. Suggesting that he repeat the test and if it still fails miserably, contact service. That's WHAT IT'S FOR.

The snowflake isn't a big deal.unless you need max range.

The climate conttol preconditioning does warm the pack, but not at a high rate. If you want the pack warmer before driving you can bump your charge limit up a couple percent, that gets the pack to charging temp. Can also set a charging schedule along with preconditioning to do this automatically.

To really heat it up:
Uplug
Get in
Set destination to a Supercharger
Press brake (and enter PIN if enabled)
Hang out in the truck for a while (depending how cold it is and how warm you want it) 10-20 minutes can do it.
Get out and plug back in.

This unleashes approximately 16kW of pack heating, but pulls down the battery SOC (can be a net range gain though due to unlocking cold capacity).

Again, that's not how Teslas work.

The precondition is mostly the interior climate, but does start to warm the battery. As you see in that thread, the battery is almost never warm enough in extreme cold temps, but it starts warming it. The Cybertruck's 4680 are more sensitive to cold than many of the other Teslas and takes longer to heat up and needs to be warmer. This isn't a bug in an individual truck, it's fleet wide and ongoing for years.

I’ve tried using a 250 kW supercharger a couple times (Winter temps) , having my cyber truck’s battery preconditioned anywhere from 30 to 45 minutes, I’ve only been able to pull anywhere from 53 kW to 98 kW just to go from 40% SOC to 75% SOC. It’s taken 40 to 45 minutes. Something is definitely not right.

One thing I noticed is that if you set it to 'leave at 8am' (for example) and then you get in at 8:15 it has already 'cooled down' and shows the snowflake...

Just remember that it's pre-conditioning and if you are not 'using' the truck after it is, then it's going to start cooling down the battery again...

Hey, I wonder... Can you set TWO pre-conditionings? One for 8am and one for 8:15am? That way, it should be pre-conditioned from about 7:50-8:15 at least...

Hmmm... something to try... Can't really give it a good test 'here' as we're starting to warm up already (lows in the 40's now as opposed to the 20's while at another place)... But you could give that a try...
