80 vs 65 will increase aero Wh/mi by 50% (v2/v1)^2. At 65mph that component is probably something like 100-125Wh/mi, so that’ll add about 60Wh/mi at 80mph, all else being equal.I tend to drive 70-80 on the highway so I know that is a factor but I wasnt expecting it too be as bad as I saw
Good to know. I'm in Ottawa and ski in Quebec weekly. Thanks!With these kind of reductions, I really hope my ski hills had charging stations for those occasional -25C days... I guess we'll be using the gaz guzler in those instances...
The good news is I did notice some hills are starting to put them in. Saint-Sauveur has an assortment of Tesla and standard Level 2 chargers, not sure how they manage their use though.
No heat pump on 2018I only charge at home and my LFP has exceed my expectation and it is doing better than 2018 LR RWD with NCA. Regen works better at similar temp (30 deg F) so far in NJ. Will see how it goes as the temp dips lower.
It was able to charge at maximum speed (242V@32A) despite cold soaked in 30 deg F overnight.
What was SOC each starting time and how many miles actual vs range in miles car showed? If you did supecharrge can you share charging speed as well? With 120 volt how many miles per hour you are getting in 35 or lower 40 f temps? Thanks again for sharing your trip data.I just did a bit of a colder weather test myself. 37F.
While plugged into 120v, I preheated for 20 min. I then put in the super charger location 25 miles away and it pre-heated the entire trip.
Trip 1:
Speed: 75mph
Wh/Mile: 352 (while preconditioning battery)
Distance: 25 miles
Heater: Set to 74 with heated wheel and seat on max.
Elevation: -30 ft
Charged 19% of the battery for 10 min.
Trip 2 (way back home)
Speed: 65mph
Wh/Mile: 241
Distance: 25 miles
Heater: no heat or heated seats/wheel. Turned on defogger twice for about 30 seconds each time.
Elevation: +30 ft

That should be fine. LFP is good at 100% however i would say dont just keep it at 100% soc for long time. .I'm charging my LFP to 100% everyday regardless of the %, How good is this charging practice? Thanks!
I am goinn to follow Tesla recommendation to charge LFP to 100% at least once a week. Works for my commute routine.That should be fine. LFP is good at 100% however i would say dont just keep it at 100% soc for long time. .

Another question : I have a 15-20 in my garage which charges my model 3 at 7-8 miles / hr currently, giving me ~60 miles overnight. On some old forum I saw that 6-20 NEMA plug can charge at 15 miles /hr. Does anyone use 6-20? Form the forums seems like it is easier and cheaper to convert a 15-20 to 6-20. Is my understanding right?
What was it before? 272 miles or 252 miles??After the last week windy trip, my full charge dropped to 248 miles.
Pic below is from four 30 miles commutes with sparse cabin heat only if it starts to fog up with 2 bacons seat heater. Daily chores to drop off/pick up my daughter/wife had cabin heat.
I got 235/248 miles although I got 200 Wh/mi, waiting in car and one preheat (cost 6 miles).

252 sometimes 253. I have 2021 SR+ LFP.What was it before? 272 miles or 252 miles??

I also have 2021 SR+ LFP, and was charging to 252 - 253 (in the app sometimes up to 254 - 255) but just recently it started to only charge to 249 - 250. Only have 2300 miles on the car. I level 1 charge to 100% every night, never used a super charger.252 sometimes 253. I have 2021 SR+ LFP.
Is it a degradation you think or just the BMS figuring it out. I hope it goes back to 252 to 253 ish. Keep us posted please.I also have 2021 SR+ LFP, and was charging to 252 - 253 (in the app sometimes up to 254 - 255) but just recently it started to only charge to 249 - 250.

Thanks for the info FARKLE!I also have 2021 SR+ LFP, and was charging to 252 - 253 (in the app sometimes up to 254 - 255) but just recently it started to only charge to 249 - 250. Only have 2300 miles on the car. I level 1 charge to 100% every night, never used a super charger.
I have never charged at a Supercharger.By any chance did you use any super chargers on your trip? If you did, how full did you charge to with them? Thanks!
I charged to full last night. Woke up this morning with 251 miles. I think it adjusts to the consumption data.Is it a degradation you think or just the BMS figuring it out. I hope it goes back to 252 to 253 ish. Keep us posted please.
