It disturbs me a little bit that owners with higher miles and/or longer ownership times have better range charge numbers than I do. I've been getting 255-258 since I hit 9k miles (after allowing time for pack balance.) Some folks are getting the same or better numbers than that and they have over 20k miles. I have a B pack... but I'm wondering if the combination of 21" wheels, pano, and having a performance makes any difference. My avg kwh is 350... which seems to be higher than most on here, but it's tough to say because not everyone reports whether they have 21's, Performance, or Pano... which all should affect avg kwh along with driving habits (most of my miles are hwy back and forth to work.) 21's are an obvious hit to efficiency. Performance could be too because you can theoretically pull more juice out of the pack when putting it to the floor, possibly leading to faster degradation on Tesla Grin launches... and the pano roof adds about 200lbs from what I've read, so that could add to the stress on the battery, over time at least. Last important factor besides battery age, mileage, driving habits, and car weight I believe is location (and more importantly climate)... Down here in GA we have hotter days during the spring/summer so maybe that leads to faster degradation than some of you folks in the northwest/northeast and SF bay area?
I know I'm still within normal ranges with my loss of rated miles, but it still concerns me I'm a little below the average (at least it seems that way)
I have 11.5k miles, you have 15k. We both have B packs and average ~350wh/mi... and yet, you get 265+ on a range charge (I've never seen anything over 258)... and IIRC my 90% is 222 on a fairly consistent basis (will check that tomorrow.) So despite the fact that we have the same 350wh/mi, my battery capacity is a good bit lower than yours even though I have less miles. It isn't a big deal, but it's there and it's noticeable. When was your car built out of curiosity?
