Model S Plaid range discussion.

Also, get a cable, Elm327, and SMT app and look at what the BMS is reporting as your nominal capacity. My X Plaid currently states 97.2 kWh. My rated range is 291 wh / mile and 100% is 334 which exactly adds up to the 97.2 kwh that SMT is reporting.

At about 14k (actually 11k on this HV battery) mine is reporting 342.2, down from 348. I charge to 80% daily. Car has only seen 99% once. Never seen below 20%. (with this pack)

Is that 97.2 kWh the nominal full pack value? What size is the buffer according to SMT?

Insomuch as you are talking about a compromise, then you are probably correct. However, since I've retired several years ago and have no need for being anywhere in a BIG hurry, like I did when I was younger, I find that I prefer the big MPGe numbers, and therefore drive 65 and 70, which is the speed limit on most interstates and highways now. But the difference between 70 and 75 is probably about 105 MPGe vs 100 MPGe? So I really shouldn't give a sugar anyway?

Just stay in the right lane

Yes, mine headed in the wrong way from the first Dyno Mode entry. Was 90.3kWh the first time a few days back. Now 82.8kWh as of yesterday afternoon (though in practical terms I still get the same awful 200-220miles actual range, with the car stating between 295 miles and 310 miles predicted range). Still overcharging horribly. Can you set the charge to 90% and it actually charge to there successfully if you monitor it? Set your notifications in the app to let you know if charging is interrupted/stopped. Both times this week I set to 90% it crapped out at 83% and 86% respectively. I then shut off charging and the car continued to climb to 100% SoC over the next 10-15 mins.

I’m pretty convinced we need new battery packs. Quite honestly would like a new car at this point (the number of issues keeps growing daily, and I’ve not been able to enjoy this car since day 1).

Happened to see this older post in the thread looking for something else. Your screen shots shows a 9 mv min/max cell difference at 86% and a later screen shot showed 390 mv difference at 6%. It's amazing the BMS wasn't just saying no and stranding you on the side the road. A typical healthy diff at 80% would be 3 or 4 mv and at 6%, 9 or 10 mv, so your battery was quite toast (at least one of the modules was). Good thing they replaced it.

Hah, yeah that car was a bit of a joke. So glad to be rid of it (buy-back for sooo many issues) and uh.. have the same car, but a year newer. Heh.

Good times. Oh and I meant to say 90 mv, not 9. I typoed out the 0.
