Lifetime Average Wh/mi

[Bugeater]

Sept and lifetime numbers. On time this time!

I'm suspecting that since we got 6.0 a couple weeks ago, our usage has gone from an average of around 350+ up to 380+. In the firmware 6 thread, others have noted similar. But the some have said their average went down with 6.0.

Whoops, last month should've said 09-02 as the record date. No trips this past month. As usual, "A" is my near-lifetime and "B" is the past month.

Heh, I drove almost exactly twice as many miles as last month; my vacation was a little over half of August, though. Anyway, amusing to me.

Oh, and a new phone means a better photo of that little total miles number!

@Jerry - Good to see I'm not alone on the mismatched lifetime A/B trip meters issue.

The decimal place is obviously precision without accuracy. I suspect a number like this: 7.83 MW would be about the limit of accuracy.

 

[Sparrow]

For the month of September I drove 510.5 miles using 116.0 kWh or 227 Wh/mi. Lifetime I have driven 17,355 miles using 4,373.3 kWh or 252 Wh/mi.

September stats:

Lifetime:
34,424.9 miles
11,479.1 kWh
333.0 Wh/mi

September:
1,910.9 miles
582.0 kWh (from car)
732.7 kWh (metered)
305.0 Wh/mi (from car)
383.4 Wh/mi (calculated)

September updates. This will probably be the peak low. It starting to get cold again.

Well that's fine, but it still doesn't explain why A and B have different data to work with.

 

[Brass Guy]

Sept 2014: 1,480.9 mi, 375.2 kWh, 253 Wh/m
Lifetime: 25,523 mi, 7514.6 kWh, 294 Wh/m

So with one complete year (13 months now) it is possible that my lifetime will average under 300, but I hardly used A/C all summer; so maybe not a typical year.

 

[paco3791]

Sept 2014: 2,295.3 mi, 625.6 kWh, 273 Wh/m
Lifetime: 22,095.5 mi, 7110.4 kWh, 322 Wh/m

1 year will be in a week or so, time flies. Glad to see I'm not the only one putting on a ton of miles though.

They don't, but they are calculated separately and the analog to binary conversion don't always result in the same number--unless you have a lot of extra bits to hide the differences. And I doubt they use long integers to calculate Wh/mi. They probably just use floats.

 

[Denarius]

Update:

Lifetime:
Denarius - 329Wh/mi, 32885 Miles, combined 19/21, 85kWh (P85+), Utah

September:
Denarius - 328Wh/mi, 3242.3 Miles, 21 only, 85kWh (P85+), Utah

I took a 1200 mile trip in September with an average speed of 83mph. That pushed my average up this month from 310 to 329.

I'm a bit tardy in posting this month, so I added Sept to my recent running list:

Lifetime:
ZBB 296 25,155 AZ 60 19 1 9/30/14
ZBB 297 23,701 AZ 60 19 1 8/31/14
ZBB 296 21,062 AZ 60 19 1 7/31/14
ZBB 294 18,065 AZ 60 19 1 6/30/14

Individual Months:
ZBB 282 1,454,5 AZ 60 19 1 Sep-14
ZBB 302 2,639.4 AZ 60 19 1 Aug-14
ZBB 312 2,996.4 AZ 60 19 1 Jul-14
ZBB 288 1,322.7 AZ 60 19 1 Jun-14

September tied for my lowest month ever (April was also 282 Wh/mi). July and August include our road trip (which drove the average up), so I'm now back to regular commuting. Its also starting to cool off here in AZ, so I expect the next couple months to help get the Lifetime average back to my previous low point of 294 (or possibly lower -- the first few day of Sept, I'm averaging 263!)...

Update: I have been doing bi-annual (Trip A) (winter/summer) Wh/mi records. My cutoff is 4-14-14 to 10-14-14. This summer's efficiency is 279 Wh/mi 13,139 miles .

I've been hunting but not finding. Where is the compiled data posted?
