(Taking a similar approach to acmotor for his i-Miev)
21000 km in 10 months
I only charge to 80% (Nissan "long life mode")
Weekday commute:
Home -> daughter school -> work: 40km. 90 minutes. No heater usually because the car pre-heats while plugged in.
work -> home: 30 km. 60 minutes. Heater used in winter (now)
All driving is suburban with max 80km/h speed limits.
I almost always drive in "D" as I don't like the slow accelerator response in "ECO".
I usually arrive home with about 30km on the GOM (guess-o-meter).
I feel using the heater on the way home reduces the potential range by 10-15km.
I only charge at home as I have no charging at work.
Saturday typically 120km but this is broken into two 60km round trips with a top-up between them.

Decided to take the Leaf for a run to Mt. Wilson. Only 63km one way, my first real trip in it. Didn't even bother to reset the trip meter although I did do an over night recharge. Unfortunately Mt. Wilson is also 1740m higher! By the time I got there range was down from 170km to 30km! Not a good look when it's 63km back home.
Most of the way back downhill range was less than distance remaining, I made a mental note to never leave home again without the EVSE. At 17 km range she-who-must-be-obeyed (turn right, turn right NOW, the Leaf NavBitch is very assertive) was giving warnings and the range digits began flashing.
By Bilpin range & distance remaining finally matched & I got in with 9km to spare. Range Anxiety? Pffft!

Looks like my driving style is ~140Wh/km

Power:
63km to Mt. Wilson at 140wh/km = 63 x 0.14 = 8.8kwh
1740m vertical for a 1493kg car + 140kg occupants = 1633 x 9.8 x 1.74 = 27.85kJ = 27.85/3600 = 7.7kwh
So total energy used = 8.8 + 7.7 = 16.5 kwh

Distance numbers:
Predicted range at trip start 170km (24kwh pack/[.14kwh/km] seems reasonable)
Claimed range remaining at Mt Wilson 30km
Difference = 170 - 30 = 140km used, 16.5kwh/140km = 118Wh/km this figure makes no sense at all, it must be an artifact.

Seems the range prediction is based on rate of power consumption. I figure 24-16.5 = 7.5kwh left in the battery at Mt. Wilson. The 30km prediction there assumes 7.5/30 = 250wh/km. My actual power consumption going up 16.5/63 = 262 Wh/km, 5% agreement good enough.

Conclusion: I need a phone app that takes vertical displacement into account, the guess-o-meter is not quite smart enough.

After 9 weeks driving Nissan LEAF- I am getting 95 to 115km on 80% - hot weather with air con appreciated, highway runs of 10km @ 100kph and 10km @80kph giving lower range.

My Leaf now has 15,000 km on the clock and is fantastic for my daily commute - 40 km each way plus side trips then charged off-peak each night. Typically has 40 to 60 km left representing range of 140 km. The commute includes 18 km each way on the Eastern Freeway at 100 kph. (106 kph on the speedo).

If I slow down to 80 kph on the freeway (eg in traffic) then I could get an extra 10 km range each way. ie. Probably 160 km range total.

Lights do not appear to make any difference to range but A/C can reduce range by up to 10 km or more in a blizzard with demister & windscreen wipers going.

The "Guess-O-Meter" actually seems to work well provided you take into account that it assumes you are going to continue driving similarly to the last 10 km or so. ie. if you are going fast up-hill it will give you a lower range estimate compared with moderate speed down-hill.

21 months old with 27000km on the clock
1 bar lost. LEAFspy Pro showing 91%SOC maximum achievable. 19.9kWh (after testing on several recharges)
I have used the RAC WA Electric Highway twice in the last month. The route is installing the charger between Bunbury and Mandurah at Harvey. It is required. Bunbury - Mandurah is 103km. Too much for the LEAF to sit at 100kph
Note, LEAF speedo is about 7-10% error so if it reads 88kph I assume I am doing 80kph.
I didn't exceed 90kph ( 81kph) and had 12km left on GOM, no air conditioning.
required trickle charging until lights go out.
Repeated driving fast recharging did raise battery temperature, and it's only been 17C so a summer's drive in 40C could be problematic.
I don't know how far below "0" on the GOM I can go.
The journey seems to average 0.145wh/km when limiting to 90kph (no headwinds)
I used the Old Coast Road and through Australind to minimise impedance on fast traffic.

we need more LEAF owners to post their data
perhaps the LEAF owners haven't really travelled to the edge of their GOM
or not as techno as i-MiEV owners seem to be.

Volt owners may not worry about EV range cos they have petrol.
similarly PHEV owners too.

Can't wait for the new forum software.
Admittedly the AEVA forum at the moment is not very user friendly, especially for adding photos and URLs

I have read in older USA forums that 12-16km below zero for 60kph, which I think is fairly true. Some of my calc's from using the LEAFspy Pro (which has a few glitches) show 2-3kWh left when GOM flashes no range (about +ve 5km)
On my 2 trips south I have had a passenger. If time falls into place I may try the run by myself to see what speed I can do and to what level of discharge I can go. Now I have a consumption value I ccan slow down if required to do so and I have a relative in Australind where I can bleed their solar power. (Australind is about 16km from Bunbury at 70kph)

I've found photomac details helpful, so me follow suit:

Mine is 2012 Leaf (second hand):
From fully charged to warning low batt, only managed to get 100km (12km left on guess-o-meter). 60 out of 100km were done on Roe Hwy at 100kph (speedometer reading).

Leaf spy screenshot at fully charged (home charging):
Image

Leaf spy screenshot at the end of the journey:
Image

From the above, I concluded Nissan Leaf (2012 model) battery is NOT 24kWh. There is no way the battery capacity is 400Volt * 60Ah. More likely 360V * 60Ah = 21.6kWh (with only 70% usable for practicality, i.e. 15kWh)

PS: During normal suburb run (no 100kph), I manage to get around 120-ish km (0.13kWh/km).

----Edited------

Oops, just found out from other forum that Nissan Leaf battery capacity is around 66.6Ah (which makes sense, since my SOH = 89%). So, it's operator error (me) not knowing how to read Leaf-spy Image

Thanks Rusdy.
I am learning the LEAFspy Pro too.
I noticed the SOC and a few others lock up during journey. I think there are some bugs to fix in the Apple iOS version.

All these experience help paint a very realistic range knowledge which reduces risk of possible disappointment.

When heading down from home (South Perth/Vic Park border) to Mandurah I hop on the Freeway at the Mill Point entrance.

These are the figures;
Leaving
Odo 25856
Time 0737
GOM 152km in Drive
SOC 90.8%

Arriving
Odo 25928 (72km)
Time 0829 ( sat at about 5% above speed limits on speedo knowing it is 7-10% conservative )
GOM 39km
SOC 38.5%

I think the SOC may be affected by the limit the user sets.
In my case I set it at VLBL ( Very Low Battery Level )
From those figures I used 52.3% SOC for 72km.
That's 1.37km / 1%SOC suggesting another 53km left! A potential total of 125km at highway speed.
Scary so I may try the Mandurah - Bunbury run alone. Luckily for me I have a brother with a power point in Australind some 14km closer than Bunbury.

Leaf and tesla tend to charge to 80%
Did you charge to max range mode 100% photo mac n rusdy?

Bmw 18.8 of 21.6 kWh usable. No 80% charge Mode
Imiev seems that 16kwh all usable

FC - the charger clicked off in Mandurah at 90.5%, 89% 90.6% and 88% and Bunbury was 86% and 84%
I moved car to second bay to top to maximum charge with the level 2 charger. I think the maximum amount was reduced by warm batteries but only by about 1%SOC

hi g4qber, from my experiment, my Leaf can't be charged all the way to 100%. 90-ish % seems the maximum. Good idea tho', me think.

Regarding bottom limit, I don't have the guts to try it. Don't want to kill the battery anyway :). However, from my experiment above, looks like the warning starts at 20-ish% SOC.

Since my post at 15K, I started running LeafSpy Pro at 18526km. State-Of-Health (SOH) was then 96%.
Now at 27779km SOH is 93%. Range has dropped about 15km - still good for my daily commute - typical 40km to work & 40km back home as per screenshots below.
Batteries after full charge = 91.8% State-Of-Charge (SOC)
ImageImageImageImageImageImage
Batteries after 80km = 38.7% SOH

Tim Isaacson has done a fantastic video of this vehicle (and many others)

Ouch! As if Nissan had predicted this to happen at exactly 100,000km and adjust the warranty accordingly!!

Had my Leaf for a week. 22,000km on the clock LeafSpy reports 85% SOH. After 1 week the SOH has dropped to 83%, don't know if I was duped or if this is just something with the car. I expected ~85% SOH given the 4yr old car and 22,000km, but drop in SOH has me a little concerned.
Used the Nissan Leaf Range Estimator app and it seemed reasonably accurate.
First week:
SOH: 85%, 85%, 85%, 84%, 84%, 84%, 83%
Hx: 82.39%, 81.86%, 81.18%, 80.82%, 80.42%, 79.95%

I guess if it keeps going down at this rate I will be eligible for a battery replacement about December :)

After 4 months of ownership, the vehicle has done 25,562km, here are some stats about my range. Note the values represent Wall to Wheels consumption, the Leaf can only show Battery to Wheels consumptions, so while my Kw/Km is 0.197, the Leaf shows it is 0.15 on the Dashboard display. I'm only really interested to know what it is costing me to operate the vehicle, anything else is meaningless to me.
Image

The average Kw/Km or Km/Kw gives a reasonably accurate expectation of range, with the obvious issues that hills, speed, wind, A/C affect the range per trip. Basically I work on 1Km/1% SoC and that seems to work well for the driving I do. My LeafSpy shows the best SoC I can get is about 93%, so realistically I am saying I can go 93Km. I'm not getting anywhere near the 120-150km range that others are saying they can get, and it is interesting that the EPA (US) is 86mi, which would translate to about 136km, so with 82% SoH I would expect about 110Km range.

I also plot the SoH, Hx and AH values after every charging day (so some gaps if I did not charge that day). My SoH is 82%:
Image

The spike is when I took the Leaf for the service. Ok, so what are Nissan service doing that causes the SoH, Hx and AH to change? Interesting after the SoH was bumped back up above 85% there was still 1 bar missing in the cars representation of SoH, so it still knew SoH was less than 85%. Hx has not come back to where it was prior to the service, no idea what that value really means, but is a bit of a concern. I saw this behaviour when I purchased the car, and I suspect that it was serviced just before I bought it, which would be consistent with what I am seeing now.

For my around town needs this car is perfect, but any trip of significant range is a problem as we have almost no charging infrastructure in Australia, and using the EVSE is a joke given they put the 15A plug on it, besides the very long time it would take to recharge anyway. 15A EVSE takes a few hours and is Ok, but there needs to be many more of them before it is a reality for any sort of longer range driving.
