Just picked up my 2022 MYP. I am not complaining, just trying to understand the range calc. With my first home charge to 90% the estimated range is 268. With an EPA range of 303, 90% would be 272.7. Just wondering if anyone knows how the calc is done for remaining range as I am I interested in just understanding.
Thank you

First of all, welcome and sorry you got a bristly intro to this forum. I lived in Colorado for 20 years and also owned a Tesla there so I can attest to the cold weather performance.
I now have a 2021 Model Y I took delivery of in August. As of this moment, my car has 5851 miles on the odometer. My range is a little lower than when I first took delivery, but its really similar. In the app/on the energy screen, it states my 90% charge is 261 miles and my 100% charge is 290 miles. I take issue with those numbers as I KNOW my car will not go that far on a charge the way I drive it and the way I use it. I am a heavy user of Autopilot, and I have been on several middle range road trips (Houston, about 200 miles, Starbase which is 390 miles, and back and forth to San Antonio which is about 100 miles). I will tell you, as I am sure you would know by searching, the efficiency of these cars and the ACTUAL RANGE is highly dependent on all kinds of things. But, the things I have found make the most difference are as follows:
- Tire pressure - I keep mine around 41 cold, heats up to maybe 43 warm
- Cruising speed - 70 on the highway takes a lot less kWh than 80. seriously, like 10-15%
- Load in the car - everyone hauls extra crap around in their car. I generally pack and travel light, but Ive found this to make a difference.
- Outside temperature - here in Austin we get to freezing occasionally, but not often so its not a big deal.
So anyway, dont take your estimated range too seriously, and switch it to % as opposed to miles. Miles is useless in my current car, and my previous car. The summary of my mileage over the 5851 miles, by the way is 302 kWh.
I look at it a little like fuel consumption in an ICE car - its just a results of a set of testing that someone did who is probably not in the same situation as you are. So, take it with a grain.
By the way, there are LOTS of pundits out there who will tell you how to maintain the battery to keep up your range. Personally, I never charge above 80% unless I know Im going on a roadtrip, I personally dont plug in every day (generally below 30% I plug in) and I use a lower charging rate than my charger can put out. I have the wall connector and it's capable of 48A, but I charge at 30A. This takes longer, but it reduces the amount of heat going into the battery. I also dont leave the car charged if I know Im not going to drive it.
So, anyway my 2c FWIW -
Cheers and welcome.
