What determines the EV range that is displayed? Is it just a guess based on the temperature or is it somehow constantly adjusting based on driving habits, temperature, etc.?

When I got my car in October the EV range went as high as 57 miles while it was in the 60s and 70s outside. Yesterday I ran the car to 0 EV range and drove on the ICE so the battery got a full recharge last night. Today it's about 52 degrees outside and the car is only showing 40 miles EV range.

I'm wondering if this is just the car guessing based on the most recent conditions and after I drive it and recharge it today the range will actually increase... or is this the actual max range I will get right now? Is the car just assuming that I will use the heater, heated seats, drive a certain way, etc. and combining that with the air temperature to say 40 miles, so if I were to drive without the heater on I would get more?

Every night, you eat out. For the last 3 nights, you spent an average of $50 at your favorite restaurant. My guess is you'll spend $50 tonight.

That's what the car is doing.

Now if you change restaurants, or eat more, eat less, have more beverages or less, this can throw off the estimate. Same with the car, but related to driving style, tire pressure, outside temps, the roads you travel, etc.
