It is the same as with the quantities of vitamins sometimes being listed with the measurements in IU (international units). It is a fixed, exact conversion from milligrams or micrograms according to a conversion factor constant. So it is an exact unit representation. 1 rated mile for a model of vehicle does equal an exact number of joules.Estimate: noun
an approximate judgment or calculation, as of the value, amount, time, size, or weight of something.
Energy is measured in joules, watt-hours, etc. Miles/kilometers is a measure of distance. Any measurement of energy remaining should be in joules (and given as a percentage)
That (326) is a representation of how much total energy there is, which due to manufacturing variability, they cannot guarantee exactly how much there will be in anyone's specific battery. People's batteries will have varying number of joules/"rated miles" in total. Therefore that total amount is an estimate. But the unit that is called a "rated mile" is not.Even if it is a 'conversion from the EPA testing procedure' as you allege, it is still an estimate. Tesla even states this on their web site: (hint - 'est' is an abbreviation for 'estimate') Sorry, but stamping your feet and shouting 'No it's not' doesn't change what it is.
First, as near as I can tell, the only source for the claim that this is a fixed conversion is your posts on this thread.It is the same as with the quantities of vitamins sometimes being listed with the measurements in IU (international units).

Just to get back to the original question, page 67 of the owner's manual has the following statement:Not sure if it is normal. Charged to 100% once and got 306 estimated miles about two month ago. After that estimates went down to 303 miles and today to 300 miles. Is it within normal behavior?
And my MYLR w/inductions after 15 months and 11,300 is also 281, too funny...MYLR with Induction wheels. 14 months ownership with 11,100 miles, and 281 miles indicated after 100% charge.
I'd be very careful with all that drafting - those trucks have taken out many a windshield. I avoid being behind trucks of any kind. Thoughts from a fellow AF retiree (and soon to be civil service retiree!)Nope, I departed Louisville for Mt Vernon at 97% (I misspoke when I said I departed Mt Vernon) it was the other way around. I drafted a big truck for the first 25 or 30 minutes to get my wh/mi down with TACC set to 72 mph (posted is 70) and ducked in/out of the left lane to pass slower cars as necessary. My arrival SoC started off at 11% but kept climbing due to judicious drafting and construction along that portion of I-64. But in the end, my average speed was just at 63 mph with the results as posted. My screen shows temp as well. And I wasn't running my Aero Caps but tire PSI was at 43 psi sometimes 44 psi.
Wow, that is pretty crazy that our cars are essentially the same age, mileage and range. Does it concern you at all it only shows 281 at full charge?And my MYLR w/inductions after 15 months and 11,300 is also 281, too funny...
Not at all that’s great. We only started with around 300 (inductions vs 19’s) so down less than 10%, seems to have leveled off too. All good!Wow, that is pretty crazy that our cars are essentially the same age, mileage and range. Does it concern you at all it only shows 281 at full charge?
Huh--well, maybe someone else can help you find that. This has been known for many years.First, as near as I can tell, the only source for the claim that this is a fixed conversion is your posts on this thread.
All of your citations are pointing out that trying to figure out the amount of energy in the battery is an estimate. Of course it is. I repeatedly pointed that out to you. It would be an estimated amount of joules too. But that was not your point. You were staying that the unit of joules was exact, but a rated mile wasn't. That is still simply false.Second, if it actually is a fixed conversion, the battery capacity is an estimate and variable, meaning it's a conversion from an estimate and making it an estimate by default.
Third, displaying a percentage as a distance is deceiving and inaccurate at best.
But finally, just to put this to rest, I will quote the owner's manual:
I think you'll find over time that we spend way too much time stressing out about range. As others have noted, there are a bunch of other threads on this same topic - it helps to do a search before you post a topic here, just FYI. Realistically, are you going to jump in and drive 300 miles (or over 4 hours) in one fell swoop? Most people don't. Personally, I'm good for about 2.5 before I need a bio/stretch break. So I stop when either the car, or my bladder, says to, and charge up. I've come to the conclusion that range is overrated, but what's important is availability of chargers and charging speed when road tripping.Not sure if it is normal. Charged to 100% once and got 306 estimated miles about two month ago. After that estimates went down to 303 miles and today to 300 miles. Is it within normal behavior?
My 2022 YP has NEVER charged more than 279. Ever. I took it in a week after purchasing and was told it was within specs.I would like to hear what other Model Y owners have as estimated range on full charge.
