Carwings Data

Sat Mar 12, 2011 12:17 pm

is it just me or does Carwings report different distances than your car does.

i reset Trip B EVERY morning.

so mileage over past week

date-car-carwings

3/11-20.5-na
3/10-20.4-12.2
3/9-41.3-40.3
3/8-33.4-32.6
3/7-18.1-17.7
3/6-18.1-17.7
3/5-87.1-75.9

anyone else seeing this? i noticed this because prelim findings (which may not be right due to some sort of math error) shows my charging efficiency could be as low as 75%

Yes, carwings shows a slightly different miles driven than the car.

I think the carwings system uses GPS to get the mileage than the car's internal info.
1st Leaf : 2/28/2011 to 5/6/2013
2nd Leaf : 5/4/2013 to 3/21/2017
Volt : 3/25/2017 to 5/25/2018
Model 3 : 5/10/2018 to ?

Well 2D GPS would report shorter distances in hilly areas but I think that its not the issue. For some reason its not tracking all trips. The other day it tracked me for 12 of 20 miles.

May be you didn't hit "yes" to sending data ?

My regular commute comes to 10.6 & 10.8 in carwings & the car.

Anything is possible but I don't consider it likely.

Yep, my Carwings data is significantly off and much more optimistic in average Miles/Kw than what the car shows.

And I do remember to accept the Carwings data screen every time I start up.

i find a small correlation between taking the MPK carwings reports multiplying that with kwh used by motor min regen plus kwh by accessories.

that does come up with a number that loosely matches my personal observations. problem is, i have exact matching numbers on several days with unmatching correlating numbers. its almost like Carwings is just providing rounded results with high tolerance values.

This is what I have collected m/kwh. The difference in miles driven doesn't answer this difference. A few more days of data gathering before I report.

And yet another data point is calculating your miles/kWh from the utility meter. Using that, which the one which probably counts the most, I'm only at 3.4 miles/kWh. And thats over 1300 miles and two month. This is far different that what CARWINGS is reporting.
