I have a 2018 Model 3 Performance model. About 23,000 miles on it. Only supercharged 6-7 times total in life of battery, only ever been to 100% SOC 4 or 5 times ever in life of battery.
today my 100% SOC reads a range of 276 miles. My daily SOC 90% is 248.
I'm taking my M3 in for service in two weeks for battery breather replacements (bad clunks when going up my local mountains) and rear trunk seal problem (rear trunk fills up when driving in hard rain).
I added that I was not happy about my battery capacity and this was the text response I got from Tesla service:
"XXX this is Tesla service. We have run several remote tests on the high voltage battery and the battery management system. The management system performs calculations to determine the expected range of the battery. All Tesla batteries will have some loss over time and will level out. While reviewing the data we noticed that the average watt hour per mile is 340 which is almost 100 over the rated 245whpm this is in conjunction with outside temperature, charging habits and the use of the vehicles accessories would explain the management systems range calculation. After reviewing all the data it was determined that the battery and management systems are working as designed and a service visit for the range concern will not be needed. We will see you XXX to address your other concerns"
I know there are like over 53 pages of discussion on range and batteries in this forum, is this response consistent with the consensus understanding and expectations for these high voltage batteries?
Every ICE vehicle I ever owned never got the EPA rated highway MPG- so look, I get it, I'm a little bit of a lead foot.
I think, overall, speaking for myself and probably a lot of others that Tesla just didn't and doesn't do a very good job of helping people understand how EV range works. I think they play a marketing and PR game with this mileage and 310 should definitely, definitely have an asterisks next to it.
310 mile rating is not actual miles and for those who don't know or understand will be setup for disappointment.
The true fact of these Model 3's is that 310 really means 279 miles of range after the first year of 9-10% degradation then, you can figure you'll only ever charge to 90% SOC, so 250 miles, and will only ever be 70-80% efficient when driving. So, doing that math, people need to understand that real world, actual, factual range of these vehicles is about 188 miles. No ifs, ands or buts.
Don't get me wrong, that's almost 3 hours of driving non stop and I think 188 miles is great, I think it's fantastic and superchargers are amazing as long as you understand you should only use them when at 10%-80% SOC (or risk sitting for a long ass time charging).
But I really, really wish my expectations had been appropriately set before all of this set in. I don't feel like I was duped exactly, I just feel like, despite all the time I've wasted in forums watching people fight over battery tech, numbers, calculations, etc has been wasted and if someone had simply just explained real world what I was buying I'd stop worrying so much about the numbers and just enjoy the ride more.
