Cold weather range reduction or battery degradation

[newbilization]

I have a Gen 2 Dual Max and have been doing daily charging at a limit to 60%. Before the snow came in this week, the 60% SOC translated to 248-249 miles. This week is super cold (in Maryland) but the car has been sitting in the garage (temp at 50-ish) when not in motion. I notice that 60% SOC only translates to 239 miles now..

Do you think the range reduction is due to cold weather or battery degradation?

I do not have your truck (gen1, large) but that reduction in range is based on recent driving characteristics. I've also seen my estimated range drop in cold weather. You can always reset the estimate in the energy panel.

It would be nigh impossible to have significant degradation on a Gen2 truck unless you kept it charged to great than 90% every day.

Keeping it around 60% like you are doing is pretty good to minimize battery degradation. I've kept my Teslas between 50-55% and only have about 2% degradation for the 2 that I've owned almost 3 years now. I'm following the same approach on my R1T I got a few months ago.

Cold weather… I’ve had 9% degradation in my ‘21 model Y with 74k on the clock and i use it as a commuter car, usually charge to 80% but charge to 100% twice a month. I also go waaay deep into the battery often arriving home anywhere from 2-5%. The degradation happened fairly early, around 30k maybe and has been pretty rock solid since. If you noodle around the interwebs, especially the limiting factor, Jordan goes way deep into the chemistry at a molecular level to explain what’s going on in the pack.
honestly, drive the car, enjoy the car and don’t sweat the battery. It’ll all be ok..

Nearly impossible to have that much degradation in such a short time unless your battery has been under extreme duress. It is almost certainly due the cold weather.

Also, don't be afraid to charge your battery. Battery degradation due to charging to a high percentage is really, really, overstated.

I have a BMW i3s that I charge to "100%" every single time and over the last 4 years I have virtually no battery degradation. I say "100" because it is impossible to charge to the full capacity of the battery because there is a portion locked away by the manufacturer to prevent you from charging to 100%.

That said, I never charge the vehicle and then let it sit there for days. I always drive it after charging to 100%. I also never let it get below 20% and let it sit there for an extended period. If that is the case, I keep it between 20 and 70% SOC.
