agree. Blink web-based data is woeful, not providing good tables, and inaccurate.
Blink itself is reliable on data, I find.

Interesting to see that wall-to-wheel efficiency is about 0.8 of that reported by the Leaf. I imagine that's the charging efficiency figure rather than some misreporting on the part of the car.

The charger isn't perfectly efficient and the batteries aren't either.

Those figures multiply against one another

My data is highly skewed because I got Blnk installed a week or so after I got the car and I also charge the car at work occassionally. So my kWhr usage is probably more complete from CARWINGS. Over time, all my home charging costs will become more accurate since I don't charge off 120V at home any more.

a. Tot miles = 1069
b. kWhr (Blnk) = 104.3
c. Miles/kWhr (Blnk) = 10.2
d. Miles/kWhr (Leaf) = 5.0
e. Miles/kWhr (CW) = 6.4
f. $ spent (Blnk) = $9.08
g. cents/mile = 0.85

Can you recalculate your mi/kwh from the Blink, correcting by adding the kWh that you used by charging at work? Otherwise, as you say, this data is highly skewed.

This is the only useful number there - since rest of it is incomplete and misleading. It is a good number.
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 ?

I agree that my numbers are skewed and misleading but this is true for anyone getting free charging at work etc. The reality is what I am paying for charging at home. If Carwings could include GPS location info where I charged and I could download that, and it would help me to come up with a more accurate number for kWhrs charged at work and other locations. The true cost of charging and therefore c/mile would be impossible (whether free or not) since I don't know what the company pays for its electric rates. The only accurate number is the kWhrs/mile and hopefully Carwings can fix that soon.

My take; if it ain't coming out of my pocket ...

Me being the data hog that I am might try to track both sets of numbers but would do it only to determine how much more I saved by plugging in at work

Posted this elsewhere, but just saw this thread. After my first full month on TOU service with a separate meter I was finally able to see exact energy usage. We went 1216 miles in 33 days (May 7 to June 9) on 336 kWh of energy (all charging at home w/ the Blink EVSE). That comes out to 3.619 m/kWh drawn from the wall. It cost me $24.06 (100% super off-peak charging at about $.07/kWh), or 1.9786 cents per mile for fuel. Carwings says we are averaging 6.3 m/kWh over 2840 total miles so far, BTW. We drive it almost all the time in Eco mode and charge to 80% to maximize regen. We probably do less than 50% freeway driving, but when on the freeway, drive at 65-70mph. We haven't had to use AC much yet (maybe 20% of the time) or heat at all.
