CT Preconditions for 100+ miles

[AlmostHuman]

Yeah my CyberTruck is only a week old in my possession and its been 30-40 deg everyday here and I see the snow flake every morning. Is it really true you only need to be concerned for charging reasons? And is it only for fast charging not Tier 1 or 2?
I also agree on the preconditioning, I have yet to get mine to do it, it would really be nice to just have a button to say "Precondition now"

My understanding is that for level 1 and 2 chargers the BMS will kick on the battery heater if needed and those slower speed chargers will not damage the battery at lower temps. I agree a precondition button would be nice.

The only reason I would not do this is part of the reason it warms the battery is to protect it while Supercharging. They found that DC fast charging cold batteries damages them more, causes micro fractures in some of the materials. It may not be enough to truly matter over the lifespan of the battery depending on how long you plan to keep it. I will always allow it to do whatever it thinks is needed.
I will say that the Cybertruck seems to be way more protective of its battery than our 2020 X. See the snowflake icon more often for sure. They can both be in the garage for the same amount of time without charging and the Cybertruck will have “Less energy availability due to cold battery” when the X has full energy available.

It was my understanding that pre conditioning is only to speed up supercharging; to shorten your time at the charger, and to help relieve pressure on the charging network. Protection of the battery is why it charges slower when it is not at the optimal temperature.

Since I had to stop by Tesla today I asked this question and they confirmed my understanding.

DC fast charging a cold battery can cause lithium plating.

This is from the article that you referenced.
“ Luckily, most modern battery management systems will restrict voltage to safe levels.”

I have a 2013 model S with 177,000 miles on it with 6.5% range loss. Preconditioning only started in recent years. Most of that cars life was before pre conditioning was introduced.

My personal experience is that Tesla knows what there doing with their battery management systems and am not concerned if I show up to charge with a cold battery, as I have done numerous times with obviously very little effect.

But if you feel more comfortable pre conditioning, more power to you.

I’ve noticed similar behavior on mine as well. I’ve noticed on some trips it has used so much energy preconditioning the battery that the amount of time saved was more in the seconds than even minutes.

So if I noticed that it’s starting to precondition significantly before I get to a supercharger I change my navigation to a manual waypoint at or near the supercharger and remove all charge stops. For me, saving three minutes isn’t really worth the extra energy and the excess noise that it makes.

Preheating the battery also helps a lot with longevity and pack health.

With the results that I’ve had, I’m not too worried about it.?

I only use Superchargers on long road trips that would require 3-6 stops in a day. For those trips I will always allow it to heat the battery if it wants.
