Lifetime Average Wh/mi

[Jeff Miller]

J, are the monthly Wh/mi numbers below cumulative or are they monthly averages?
(I assume the latter, but want to confirm).


edit: Actually, looking more carefully,
I see from you cumulative total that they must be monthly.

Btw Jeff, where do you post the stats, I remember occasionally seeing it here, but don't know if there's an up to date table somewhere as a quicklink...

Finally getting around to updating this:

Signature VIN#936, 21" tires:

Cumulative since purchase (Nov 2012): 18.3K miles, 374Wh/mi
Last 3000 miles: 382Wh/mi.

Location: SF Bay Area
Driving: Mostly city/local commuting, occasional freeway drives.

I'm guessing my higher figures are due to mostly local driving and a heavier-than-usual foot

P85 w/ 21's mostly (19"s have similar #'s so far)

368 Whr/mi w/out race days


375Whr/mi overall (16 months- 22,000mi)

Mario, I'm going to post all the raw data in a spreadsheet in case anyone wants play with it, and I'm also going to post a bunch of graphs and tables in a pdf file once I have had a chance to finish collating the data. Should be within a week or so.

OK What's wrong with my math here? For those of us who have the 85Kwh battery, that represents 85,000 wh. If my real-drive average for the 4,000 mile+ life of car so far is 337 wh/mile (it is), then the 85,000 watt hour battery should take me (85,000/337) 252.2 miles on a full range charge. On a realistic basis, I don't think that's happening. Is my calculation correct, and if so, why don't I seem to be getting 252 miles on a full charge??

You don't get full access to all 85KWh. Speculation is you may have real world access to between ~75-80KWh of it (i.e. on a "100%" charge to "0%" discharge you might have only 75KWh for driving and all the other electrical loads... HVAC, consoles, lighting, etc.)

I took a snapshot on April 10, about a day or two after getting 5.9 (the .94 flavor) and 2 weeks after getting the .88 flavor. Odo when I got .88 was 16818.

I think this means I averaged 591.4 Wh/mi over the last 10 days. I'm sure someone will check my math.

I have driven 78kWh from 100% to charge now and beyond (12km beyond) and had by estimate ca 15km left until the battery would have stopped me. So my personal estimate is that I can use ca 80kWh. But that's really pushing it

Not a Tesla Motors official graphic, but it's probably fairly accurate.
And most likely this generic guide applies to a completely new and balanced battery pack (i.e. a best case scenario, total usable KWh will decrease over time)

Sorry, long lag in updating my numbers

60kw, 19" wheels, Washington DC, no air suspension

20619 miles, 320wh/mile: this winter really hurt my numbers

 

[gregincal]

My overall average keeps getting lower. This was also a record for my commute at 284 Wh/mi (I think my previous record was 294). Of course good Wh/mi generally means that there was more traffic slowing me down (but not stop and go, which takes a lot more energy).

I picked up my car about a month ago. i feel like i drive really slow.

Note, you never get to charge to 100% of the real battery capacity. To protect the longevity/life of the battery, TM has determined a safe (but strictly off limits) cap... a self imposed lower 100% level. Though I do not know if the 85kWh number reflects this or not.

There are other threads here on the forums that discuss in full detail.

Back on topic now...

I'd love to see a future firmware update that lets me use my trip meters for trips, but still provides access to my lifetime average. I'd also appreciate an automatic trip meter (one that resets when you exit the vehicle), and a per-driver meter.

Agreed!!
