So I haven't been driving my car much since the pandemic allowed me to work at home, in fact, since March, I've only put about 2,000 miles on my Tesla. But, every couple of weeks, I do have to go to the office, which is a 85 mile round trip.
Yesterday I did that drive, and noticed some weird behavior with the "Range Remaining" figure on the screen. And, yes, before a bunch of you go off on "you should have that set to % remaining, then you won't see this" comments, I've tried both ways, and frankly, I like the range remaining more than % remaining. I regularly charge my car at home to 80%, which shows as 250 miles remaining. As I stated earlier, my round trip commute is 85.3 miles. From the car screen, I used 19 kWh of electricity, with an efficiency score of 227 Wh/mi. But, after doing that drive, my range remaining was only 134 miles. So, I drove 85 miles, with a pretty good efficiency score, but I used 116 miles of electricity. Doesn't add up. But, I did have sentry mode on while the car was in the parking garage at work for 11 hours, although only had one alert. So, was puzzled, but didn't think much more about it.
Now, the strange part. Later in the evening, I went out in the garage to plug the car in. I get the notification on my phone that the car had just started charging, with battery at 150 miles. Whoa, where did the 16 miles come from? Did they just appear in my battery? Do I have some kind of wireless charging going on here? A little over 3 hours later, I get the notification that the car had finished charging, this time reporting the battery at 249 miles. So, anybody have any rationale for A) why my range drops so much even though the efficiency score is pretty good, and B) where the 16 miles of range came from?
Background, 2018 LR RWD, 21,000 miles, lifetime efficiency score of 238 Wh/mi, temperature range between 55 and 75, mostly highway driving at 75-80 mph, except for about 15 miles of 20-25 mph stop and go.
