Interesting. I had thought it was -5Celcius for AC charging. Maybe it allowed charging because the -5C was ambient and not necessarily battery pack temp

Scheduled battery preheating vs. battery degradation
- Thread starter bumcurriculum
- Start date
I may have missed someone saying this already...
My 2016 X scolds me if I haven't preconditioned before getting to a supercharger and goes on to tell me that charging time will be extended by 10 - 15 minutes while it preconditions while plugged in to the supercharger, before charging starts. The charging rate is very slow while it preconditions.

Thanks for answer, Åke!
But the SC will use higher effect when the battery is warmed up by the preconditioning, right? May be it will be the same result for battery life? But Tesla want to show that it takes shorter time to charge therefore they use higher effect. Time is what mostly user is interested in. The precondition also use a lot of energy, I can see in my car. 75 kW/2019 RWD.

Yes, but a preconditioned battery is above 40C, which make it much less prone to develope lithium plating.
The battery heating will be on for a part of the supercharging session.
A completely preconditioned battery probably (as in: I never tested) use more battery heating in the Supercharger so the difference might be very small or null.
I had to supercharge once without preconditioning in the winter and was chocked to see 130kW immediatly (Supercharger V2, that otherwise max out at 135-140kW).
You have good answers, Åke!
I am happy to read your thoughts about battery and charging for Model 3/Tesla.
