Could you let us know: How many rated miles you have right now, at what %? That's the easiest way to determine your approximate battery health. So just look at the rated miles, switch to %, and report here.
A good battery will have ~279 rmi @ 90% (many cars have recently gone to more like 272 rmi @90%, but it's probably temporary).
The car does not count usage while in Park. Also you have a P3D+, so 220 miles on the freeway is what you should expect for a perfectly functioning vehicle. If you drive that continuously on the freeway, with no elevation gain, no stopping, I expect you'll see something along the lines of 65 "kWh" of consumption.
If you want:
Put car in drive, make a note of the miles & the %, and do a fairly long, continuous drive. Do 150 miles at least, do not stop. Do not put in Park. You really can't stop.
Report:
Wh/mi, miles traveled, the starting rated miles & %, and the final rated miles (and % if you want). We can then figure out your battery health and overall approximate available energy. This isn't really necessary, but it's a little more info than just rated miles & %. Maybe on your next trip to Vegas...
A brand new car appears to have about ~71-72 "kWh" available for a full discharge from 310 to 0. They're meter kWh, so they may not be actual kWh.
The only thing that is relevant is to compare kWh available to other vehicles - the actual "kWh" displayed doesn't really reflect anything important in an absolute sense because it's not calibrated. I haven't seen any reports of any vehicles showing more than about 72 "kWh" for a full discharge, assuming that the net elevation gain was not negative, of course (elevation is like having extra battery capacity, and it's a way you can get the meter to display more than 72 "kWh," since last charge, in rare situations).
Yea at 90% everyday usage was showing from what I recall many times 2754 miles rmi? I don't know what's rmi, does it mean that's shown on the Green Battery? I don't even count that, that would be a dream.
When was the last time you charged? What % did you charge to? Did you spend any time sitting in the car in Park? Did you use Sentry Mode? Do you use Cabin Overheat Protection?
You're missing my point here - the car does not count usage spent in Park - which can be considerable!
Charge your car to 80 or 90% and report the % AND the rated miles.
While energy used in Park over multiple days is relevant for EFFICIENCY, it's not relevant for RANGE. This is because usually (there are rare exceptions) when range matters, you do it all in one shot and there is no time spent in Park.
I'm not saying there is nothing wrong with your battery - but we need more information.
Ah, then, in that case, it looks like you have some normal degradation (likely from charging to 100% and draining to well below 10% all the time) but nothing serious.
Your usage is similar to mine lifetime average of a little over 320 Wh/mi, lately with the new firmware and the warmer weather I'm getting 250 - 280 Wh / mile with AC on.
It looks like your battery is perfectly healthy to me. As for what it's reporting that's weird and I'd need more data like if it was parked at any time with AC on or sentry mode, etc.
Last time I charge was last Friday to Saturday when I reported here it was showing 99% then I went back again and was 100%, accordingly to Tesla Technician it was 99.97%. I did stayed inside in Park about 5min on Saturday and that was it at 71-73 degrees, kids sleeping. No for this CHILL test purpose I have turned off Sentry Mode. Yes I do have Cabin Overheat protection, but again... the technician told me the Kwh displayed DOES account for all of those drains. It should be accounted into the 57kwh I have consumed, unless that's not a fact.
Tesla technician said it does account EVERY usage from the car, even in Park, Sentry Mode when we are away, Teslacam.. I emphasized that 5 times.
So this should include also Park not? I understand that affects efficiency, but also it affects kwh spent, per technician, it's included in the 57kwh displayed.
I do get 250-280 wh/mi as well driving regularly, but do you get 200miles with 95% of battery used, that's what I got with Chill mode, sentry mode off.
I will try to get those extra information and Alan, again, you've been awesome man! I really appreciate it and ALL I hope is that I am wrong. But then why the technician constantly asserted and affirmed ALL TESLA MODEL 3 has the same battery capacity.. over 1 OEM part, range is tweaked on firmware/software.
Ok. This is fairly typical these days (latest software seems to have "degraded" many batteries - it'll probably come back at some point). Mine dropped from 310 to about 300 miles in late July.
Did you charge to 100% just as a test? Typically I would not do this for every day driving...and also don't draw it down to such a low % except very occasionally or on road trips.
So your full available capacity currently (as measured by the in-car meter) is 300rmi * 230Wh/rmi = 69 "kWh" (as compared to 71.3 "kWh" for a new battery). Again, quotes because these aren't actual kWh.
You got 57 "kWh" out of it. So you're "missing" 12 "kWh".
Since you did not charge since Saturday, if you park your car outside, it's quite conceivable that over 4 days you could use 12 "kWh" (50 rated miles) in vampire drain (it would be a minimum of 1kWh over that period and as much as 3kWh), sitting in Park, using Sentry, using 3rd party apps, opening the door for whatever reason, car keeping the cabin below 105F for ~10 hours (can't remember the exact time) after you leave the car, etc.
1) Do you use TeslaCam?
2) Did you use Sentry since Saturday?
3) Do you use Cabin Overheat Protection?
4) Do you use any apps?
At your lifetime 320Wh/mi efficiency, your current "real-world" range is:
230Wh/rmi / (320 Wh/mi) * 300rmi = 216 miles.
But you actually just did 280Wh/mi (probably a bunch of around-town efficient driving), so that would be:
230Wh/rmi / (280Wh/mi) * 300rmi = 246 miles
But those would only be achievable if you drove continuously, started at 100%, and drove to 0%.
These results are normal and expected for the P3D+.
Yea I wasn't even checking the updates and how was affecting or not.. as I rarely charge 100%. Most of times I charge 90% showing 274 miles... this CHILL test I did was the 1st time ever I was using % on battery as someone told me to here.
I did charge 100% last Friday to Saturday morning, I mean, when I saw was 99%, came here to report and by the time I went back to check again, 100% finally showed up... detail, the night before I had 90% charged when I plugged in to charge 10% overnight.
Yes I know, I did for tests reason, I hate when is even 20% yellow. I had BMW i3 70 miles electric range! haha
Where did you get the 230 Wh/rmi? What does this mean?
Vampire drain was told that's included on the 57 kwh rate displayed... again, I doubt it but let's go with this line... I didn't use none 3rd party Apps, I just have Tesla App, Sentry Mode always off.... hum.. ok not true... I turned on manually on Sunday as I parked in a crowded Mall, it showed 58 events when I was back....
As for keeping the cabin below... that's the only thing I can imagine that drains.. specially on this summer... but my car is always parked inside my garage... Saturday was parked outside my friends house in La Canada, was hot... so give or take... 5 hrs parked outside...
Sunday was at the Mall... interior parked, not outside, I remember checking car temperature at 85... but then 58 Sentry Mode Events...
Then Monday and Today back to school, lots of local driving, but again, paying a lot of attention to not speed and trying to "coast" ...
1) Teslacam - Yes I do let it on.
2) Auto Sentry has been turned off for this CHILL test period... only Sunday I turned on manually and recorded 58 events.
3) Yes Cabin always ON since day 1.
4) No I don't trust any 3rd party Apps besides Tesla.
Again, what's with the 230 wh/rmi?.. if that's true then 216 miles is EXACTLY what I am getting now in real world... on CHILL mode though.
Yes since last charge it is 280 wh/mi as you saw pictures... around town was only Yesterday and Today. Saturday/Sunday were all freeways... about 165 miles all freeway.
So from what you are saying my battery is fine, but I "lost" 30 miles of real world to vampire drain? 246-216...?
Then why would some if not majority of folks here reporting 275 miles actual range in average? While apparently me and you are getting 216 miles driving + 30 miles vampire drain?
I could turn off cabin heat protection, sentry mode, and Teslacam and redo this test on the 150 miles test you have recommended also...
Really appreciate your input here Alan, should buy you a beer when I stop down in SD.
