FWIW - my Blink reports about 3.73 kW draw from the wall (0.932 kWh every 15 minutes). This would be about 0.62 kWh every 15 minutes - you're pretty close.

My 100% gid count is 265. When it was new I got 271.
Sounds bad... but then there's shenanigans like this:

What was your dash energy economy? Was is below 4 m/kWh?
It was 3.9. I went 85.8 miles on that charge.
I'm pretty sure I reset the mi/kWh gauge before I started. Tony says super car...

Tomorrow: dead to 100% from the wall measurement. :)

Look forward to that data point! And yes, 85.9 miles at 3.9 m/kWh seems a tad high. I didn't realize your car read 271 Gid when it was new. Losing 6 Gids over the course of a Sacramento summer would be pretty good! Although, given the wide range of results we've witnessed with Gids, I'm much less willing to take them at their face value.

Teaser: I borrowed a GID meter on Wednesday. Will have it until coming Wednesday morning. Interesting data ... will post when I have it all collected. :) And you guys may go hog wild figuring it out ;)

Ok ... let me explain why I was being so brusque. The data being collected shows some unexpected "stuff", but some of the recording is being done by my son early in the morning when he leaves, and he is a little less ... let's say ... fastidious ... than he could be. In other words, there may be an inconsistency or two in recording. And, secondly, rather than start a complex analysis with only partial data, I think it's better to have the entire set to analyze.

I'll have the GID meter thru at least Wednesday, not sure if I can extend in order to run another turtle-to-100% event, also subject to my son's schedule in needing the car.

HTH :)

Since not everyone has an SOC meter but many of us (all will a little effort) have a means to record the total power used for a full charge. Parital data is welcome (Ex: VLBW to 100%) but please make a note. I'll start with the two datapoints I know of today. Would be very interesting to see the range we have out there.

TickTock: 21.7 kWh Dead to 100 from the wall (20.04 kWh actually entering the battery)
vegastar: 25.5 kWh Turtle to 100 from the wall

[Edit: added link to the compilation]
Leaf Capacity Variation
I cross posted in Tony's cold temp thread: http://www.mynissanleaf.com/viewtopic.p ... 60#p243033

Well, here's the imperfect data:
Outside Temp 28-32 F, fog/freezing fog, no wind. Car charged to 100% overnight in uninsulated garage (battery might have been a bit warmer, maybe 35-40 F, showed 4 bars to start). Pre-warmed car (on L1 does consume some of the battery) but no climate control during driving.

60.7 mi to LBW, 71.0 mi to VLBW, 80.5 mi to Turtle, 80.7 mi total, about 2 hrs total drive time.
Edit: 4.3 mi/KWH, reset at beginning of trip.

Charging: Start 12:20pm, finish ~06:30 next morning, (~18 hrs L1), 25.37 KWH (Killa-Watts)

Driving Estimate: 3 mi for coffee, 1hr off, 3 mi back at 35 mph on city streets, 3mi@35city, 3@45HW, 3mi@30city, 5mi@50HW, 16 mi@55-65FW, 5mi@35city. Unfortunately, nothing was really flat. About 400ft net elevation rise outbound. LBW occurred on the freeway about 10 mi out of town. VLBW occurred as I was coming into town and the dreaded flashing "4" stayed that way for another 10 mi. Most of the VLBW was at 25-35 mph. I circled the block 2-3 times until Turtle. Looking back at this, I think under level conditions and charging/pre-heating on L2, I could have easily gotten 85 mi at similar driving speeds. I probably wasn't at a full 12 bars to start the drive.

The car is 15mo old and has about 8500 mi. Looks like I'm close to others. Hope this helps the collective cause.
