Gid count on full charge: 269

Miles on car: 7600

Length of ownership: 9 months

100% charging frequency: once or twice a month

Don't you think temperature exposure, and depth of charge, and probably a few others might be important?
 
Gid count on full charge: 277, 278, 276, 279, 278 (how many do you want to know about?)

Miles on car: 14,182

Length of ownership: 14 months

100% charging frequency: currently 3-5 times a month. will soon charge to 100% daily starting April 2nd. i guess, maybe i shoulda waited till then to reply
 
Gid max: 280 (279 typical)
100% frq: 2-3x week
Odo miles: 11,000
Leaf age: 9 months

Gid count on full charge this past week: 280, 280, 280, 280, 279, 274, 278 (lowest ever 267; highest 281 about 3x)

Miles on car: started the week at 18,000+; ended just shy of 19,000

Length of ownership: 10.75 months

100% charging frequency: around 50% of the time
 
Typical gids 100% charge: 272-276

Minimum gids 100% charge: 260 gids (gids on changing each bar adjusted downward. BMS adjusted gids upward on power cicle)

Maximum gids 100% charge: 282 (charge restarted after 280 gids full charge)

Length of ownership: 8.5 months

100% charge frequency: 5 per week

Odometer: 22200km (13870 miles)
 
For March:
Overnight temps typically around 50 deg F. All charging done beginning 12:10 am.

Almost all charging done to 100%. Full charges done so far in March = 16

LEAF delivered March 30, 2011

Miles at end of day March 25, 2012 = 11,105

278 is most common. I've seen 280 once.
9 mo old, 6k miles. Always charge to 80% by 6am and occasionally extend to 100% between 6 and 8am if I need to drive 51.5mi to consulting work. At work I plug in for a 2nd daily full charge which usually ends 272-277gids.

PS usually I clear the trip meter and mi/kwh meter on each trip and have been trying to build a database relating mi/kwh to mi/gid and thus Wh/gid.. So far ranges from 67-77wh/gid and there is a correlation to efficiency... So many other variables though, it's hard to get solid data..

You might make you test to drive at exactly 3.9 miles/kWh and see if that doesn't correspond to 0.256 kWh per mile (21kW / 82 miles), so:

256wH / 73 = 3.506 Gid per mile
256wH / 74 = 3.459 Gid per mile
256wH / 75 = 3.413 Gid per mile


73 available watt/hour per Gid : 281 / 3.506 = 80.14 miles

74 available watt/hour per Gid : 281 / 3.459= 81.226 miles

75 available watt/hour per Gid : 281 / 3.413= 82.33 miles

in your case, i would reset one of your trip meters daily and log your charge (if possible) or at least the amount of time charged and type of charge used.

i tried tracking "bar use" and GID use. i ended up with more footnotes than data points.

the car simply reacts too differently to too many different scenarios

examples; first bar lost after overnight park in garage.
bar lost after driving for 30 minutes, one hour, etc (temperature dependent)

also noticed huge performance jumps every 10º jump in average temps.

first bar lost if charge complete recently.
bar lost if charge completed and car sat 4+ hours...
the list goes on and on.

i ended up with a ton of numbers, sorted them about 5 different ways and still got a mess.

but..if interested. generally speaking on the freeway at 57 mph temps mid 40's i was averaging .23 to .28 miles per GID. this was done on 25 mile jaunt down I-5 which required crossing Nisqually Valley so did run in both directions (this is a 5 mile peak to peak dip to about -20 feet below sea level. the Marsh is what prevents the freeway from flooding)

i made the run in both directions 5 times on different days. weather was a factor since once was in pretty heavy rain but that was not the lowest performance day (.26) west to east (I-5 bends around the southern tip of Puget Sound before turning north again after Tacoma. makes for REALLY crappy driving in early morning and late afternoon sunny days!) was better with each daily trip always better by a small margin

i tried to monitor GID in town but the range on that was between .22 and .35 which was too much.

So, 281 Gids / 80 miles equals 3.5 Gids per mile.
This jives pretty well with the ~ 3 miles per hour on the charging time display I've been seeing in my driving around town. Note that each hour to charge on 120V is about 11 Gids. It's a very linear relationship, but the granularity is much lower. Which could be a good thing when you are doing mental math to correlate it to the odometer.
 
If possible, I think it'd also be useful to report battery pack voltage along with GID count at 100% charge...
 
Pack voltage reads 393.5 or 394V at 100% charge.

4/3 280
4/2 274
4/1 278
3/29 280

it bounces around a bit and most measurements taken 3-4 hours after charge completion but still no signs of any capacity loss unless you want to count .4% (difference between 281 and 280) as permanent loss
