I've had related issues and have posted my experience in nissanlies.com
Good luck! and let us know how it goes. Here's another site by another LEAF owner with problems: Wilting LEAFleafowner234 said:I've had related issues and have posted my experience in nissanlies.com
Perhaps you didn't notice that Ed is using a Leaf that has the firmware known to have the potential to be wildly inaccurate. He hasn't bothered to get the P3227 update and then states that the LBC is wildly inaccurate... guess he is only a year or so behind Nissan, but apparently came up with the info independently.drees said:Anyway, I an very certain that if your P3227 updated car is reporting ~20% capacity loss, it will also take ~20% less energy from the wall than a new car to fully recharge from turtle to 100%.
edatoakrun said:So you evidently need a combination of very high ambient temps, very high kWh use and miles driven per day (and perhaps, as exacerbated in the AVTA test, by extreme cycling of SOC) to degrade a battery to 70% EOL by 60k or 70k miles over a short time period.
Unfortunately, we don't have data over any longer time periods, since, AFAIK, no one has done an accurate range/capacity test of a LEAF with either 4 bar loss or high miles.
The only range test of an 8 capacity bar LEAF, AFAIK, reports that Blue494, with ~38% LBC indicated capacity loss, went 59.3 miles, which we now know (from all the AVTA test data) is only ~22% less miles than the average capacity of the four "new" LEAFs tested by AVTA would have completed (~21 kWh x ~3.6 m/kwh) = ~75.6 miles.
Unfortunately, the wiki continues to use the incorrect 4.0 m/kWh, and so, an incorrect total miles, for a "new" LEAF, in it's summary.

When doing some short tests of about 20 miles or so on an uncrowded freeway at 55, according to the dash, my miles per kwh seem to constantly be a little higher then the chart in your signature. Does the chart assume 2 passengers? I do run my tires at 40psi, but didn't think that was enough to explain the difference. I drive a 13.
Thanks

Nissan has done a huge disservice to EVs by not making the real world range of the LEAF clearly apparent.
Your choice of the LEAF for a 54 mile required round trip was doomed to failure from the start.
Talked with a new salesman who had just passed his LEAF salesman test the other day while doing DCQC.
His primary question: "How valid is the 84 mile range rating?"
I explained based on three years experience driving the LEAF that for most people it is a 40 to 60 mile range vehicle in moderate weather, and a 30 to 45 mile range vehicle in cold 20F weather unless you have the heat pump heater.
That is what needs to be on the salesman test, and included on all Nissan publications and sales documents in bold letters like the warnings on cigarette packs

mwalsh said:After 3 years for me, winter or summer, even with a fair bit of degradation, 54 miles is still doable very easily, even at full highway speeds, providing it's over relatively flat ground.
You still have to be careful with a 34 mile round trip but less concern in OC.tcherniaev said:I just recommended LEAF to a friend of mine who's commute is 17 miles each way. He is a perfect candidate for LEAF driver -- he can even drive few miles during lunch and still make it home OK. Plus he will be driving right by Nissan's QC on the way home.
I agree.mwalsh said:IMO, what Nissan hasn't done adequately is to explain that there are a whole range of variables which could potentially stop you from achieving the advertised range ...

...So, either you're right and everybody else is wrong...
Sublime
From the battery (from the wall):
45mph = 4.85mi/kWh (3.94mi/kWh)
60mph = 3.70mi/kWh (3.04mi/kWh)
70mph = 2.92mi/kWh (2.48mi/kWh)

You still don’t seem top get the point, Tony
All evidence from credible sources that I am aware of indicates that a new 2011-12 LEAF could not drive "84 - 89 miles in controlled 100kmh (64-65mph on the speedometer) testing..." using the controls you claim.
Everyone can decide for themselves which data sources they believe to be of higher integrity.
four test LEAFs between 99.9 to 105.8 miles at 45 mph. So, while is obviously incorrect to state that new LEAFs all have the same range, you can see that in this test they averaged ~4.9 m/kWh for the group.

I'm going to guess that "4.9" number above is your calculation based on your belief on how much usable energy the battery has. Why don't you first answer if the battery has 21.384kWh useable when new at room temperature or some other amount...
edatoakrun:
...On-topic, page five of the update below has a chart showing variable percentages of total capacity available and variable efficiency, resulting in the final range of the four test LEAFs between 99.9 to 105.8 miles at 45 mph.
So, while is obviously incorrect to state that new LEAFs all have the same range, you can see that in this test they averaged ~4.9 m/kWh for the group.

You, and those "many other folks" (whoever they are) who you state reproduced your test results, are free to believe whatever you like Tony.="TonyWilliams"
...I guess myself and the many other folks who physically have done this with the controls I have specified find your observation wrong...

Though we don't know if the AVT tests were at precisely "room temperature"...
The BOS available battery capacities, miles driven, and more data, for each of the four test LEAFs was at the link right below the quote you copied-and-pasted. One of the four's LBC did allow ~21.4 kWh, and the other three less, in this single discharge test.
DougWantsALeaf said:Tony,
Besides incidental posts here, are there any figures out there as to the spread in car ranges (or more specifically GIDs)? It seems like it might by 10% or more high to low.
Thanks

Ok, we are getting somewhere. There's data that you and I both "believe" in (that I generally refer to as "facts").
So, the next simple question is either I'm a "big fat liar" and faking the tests that myself and others have done and documented over years now on this forum, or...
...the Nissan LEAF goes 85.2 miles (plus or minus a few, based on our tests) divided by 21.4kWh equals (drum roll) 4 miles per kWh.
Obviously, if the heater or air conditioner were on, then the same test might get, oh say, 3.6 miles per kWh.
I'll let the reader decide. I suspect your reputation here might skew the "belief" against your cause to prove me wrong.
