From a link in the 1st post, it looks like it's 188 miles.

'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)
'06 Prius

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Add me to the list! 114.4 miles! First time trying a 100% to turtle mode test. Started & stopped same elevation. I don't know what my miles/kwh were for the trip, as it was split from Saturday through today, but I know it was over 6.0.

My GOM estimate shot up sky high after my test too. Previously an 80% charge would give me a GOM estimate of 78 miles. Now it's telling me 97 miles. Hah. The miles were dropping like a rock this morning though on the way to work. Still made it to work though with plenty miles above 78, what I've typically gotten on an 80% charge. The cell balancing seems to have been way off previously. The last 10% on the battery lasted forever yesterday.

Re: 100 Mile Club, 200 km, 300 km, 200 Mile Club (24kWh LEAF)

Sun Nov 06, 2016 2:27 pm

I was only able to complete eight range/capacity tests in the last year on my usual mountainous route from my home to Burney Falls State Park and back, using the charge allowed from "100%" to ~VLBW, since my last post on the previous page.

I completed two trips over 100 miles, bringing my LEAFs total of trips over 100 mile-on-a-charge to thirty-two since delivery.

It has quite clear for many years now that my LBC is significantly pessimistic in over-reporting capacity loss, and apparently by a similar percentage that it has been under-reporting kWh use.

So, I estimated the actual kWh use anjd m/kWh in all the entries below by multiplying the kWh use from the dash/navscreen, and the Carwings kWh use reports by 1.11, which is the ~the average under-report of kWh use over the year, calculated by using an external meter to measure the kWh my pack accepts from the grid.

The most significant change in the last two years is that my LEAF's LBC's pessimism no longer seems to be increasing rapidly, and appears to be have remained between nine and twelve percent for the entire time.

I do not use LBC data for any purposes (other than ending these range/capacity tests at ~the VLBW, which of course is set by the LBC) and suggest anyone wanting to know their pack's actual capacity do the same.

I don't know how much longer I will keep my LEAF, but it seems very possible now that at ten years and ~90 k miles my LEAF would still exceed 100 miles of range, under favorable conditions Nissan defined in its sales disclosure.

Applying the EPA's LA4 test cycle, also less commonly referred to as the Urban Dynamometer Driving Schedule (UDDS), Nissan came up with some real-world range numbers for the Leaf. Here's an overview of the range variations we can expect from the Leaf:
Cruising at 38 miles per hour with ambient temps of 68 degrees, you could squeeze 138 miles out of the Leaf.
Averaging 24 mph in city traffic drops range to 105 miles, assuming air conditioning (A/C) is not in use on a 77-degree day.
In heavy stop-and-go traffic, averaging just 6 mph with temps of 86 degrees and A/C on, range drops to 47 miles.
At 55 mph on the highway in 95 degree temps and A/C on, expect range to be 70 miles.
Winter temps of 14 degrees with the heater on, will drop range to 62 miles in stop-and-go traffic, assuming an average speed of 15 mph.

http://www.autoblog.com/2010/06/14/niss ... dual-resu/

Under those test conditions, I expect my LEAF would have had ~133 miles of range when new, had ~118 miles of range last May, five years from delivery, and if capacity loss continues at ~the same rate, should still have about 100 miles of range in May 2021.

Range loss has been somewhat lower than capacity loss due to efficiency increases, and the ranges I get on my tests are close to (at the same temperature) to a 38 mph constant/level test, since the lower average speed, lower tire rolling resistance and higher pressures (45-48 PSI) closely offsets the large kWh loss to regen on this mountainous route with numerous stops (see the 8/13/16 NC regen report, 8.1 kWh nominal, ~9 kWh actual, below).

Remember, my LEAF's pack still has ~2.3 kWh left, or ~14 to 16 slow miles past the VLBW range results below:

I already posted details on that last trip, including the various ways to calculate m/kwh

~87.6 of the miles, including the two pass ascents, were identical in all of the trips, and shown within elevation profile (8/13/16 trip, with ~0.65 miles not mapped) below:

...And while there is, IMO, little chance my pack has actually lost ~31% of available (or total) capacity since delivery as my LBC indicates, I estimate (from metered recharge capacity) that my available capacity is down ~20% from that available from a 24kWh total pack, and probably about 17% less than It had available at delivery ~47k miles ago.

viewtopic.php?f=30&t=8802&start=7620

Last years post on 100+ mile trips, copied from previous page:

edatoakrun wrote:Nine more actual 100+ mile trips to add to the 22 odometer (21 actual, the 100.0 odometer mile trip was probably ~99.9 actual m) I posted on p 75.

So I'm at 30 total now, by either metric.

Seven were on my usual range/capacity route, a relatively slow course but with ~7000 ft total ascent and descent, all results since last July 15 posted below.

The kWh are nominal, as reported by CarWings and the dash/nav screen m/kWh displays.

The miles are odometer and actual as corrected using google maps, for some of the trips.

14.1 kWh 93.3 m (loaner tire, passenger)

10/14/15

14.1 kWh, 100.6 m (~100.9 actual, one ~new front tire)

I also made two 100+ mile runs on trips back from the Bay area last summer, both with small net ascents.

As mentioned here:
Capacity Losses 2011/12 Leafs-Was(Lost a bar...)

viewtopic.php?f=30&t=8802&start=7340

The first was on 7/29/15, 101.9 m (~102.1 actual) from Winters to Corning, ending with 31 gids reported by the LBC.

The second was on 9/8/15 from Vacaville to Corning, ~14.7 kWh,112.6 m (~112.8 m actual) to VLBW, 14.8 kWh 114.2/114 .4 total miles to destination.

The most interesting aspect of this trip was that I drove 25.8 m from LBW to VLBW, meaning the LBC let me use ~3.3 kWh nominal (~3.6 kWh actual) between the two warnings, and so the average Wh/gid was ~132 nominal (~144 actual) during that segment, the highest I've ever seen.

The first Snow of the season is forecast for Thanksgiving, and I'm not likely to see warm enough conditions to hit 100 miles without driving past the VLBW until next spring.

My LBC report is at ~73.5% now, so it's likely my future 100+ mile trips will be using only nine (or fewer) capacity bars.

I was wrong on that last point.

Although I had lost over 30% of LBC indicated capacity by Summer, my LEAF did not lose the tenth capacity bar until 9/15/16.

It was looking like my LEAF's OE battery's streak of over-100-mile trips using only capacity above the VLBW was probably over, but I picked up # thirty-three last week.

kWh use reports, ranked from LEAST to most credible:

8/29/17

LBC report: 12 kWh used, 104.2 miles (accurate odometer) 8.7 m/kWh!!! Why oh why does anyone take LBC data seriously?

8.1 m/kWh shown on the Nav screen.

Carwings/Nissan connect: 12.9 kWh 101.7 miles (~2.5% under-report) 7.9 m/kWh (identical to dash m/kWh display) .

Actual: 14.4 kWh (est.) 104.2 miles (odometer) ~7.3 m/kWh (est.)

Not too bad, for a LEAF pack with ~55k miles, after seven North Valley hot Summers, and due to lose capacity bar # nine, any day now.

Vacaville to Orland CA, and I didn't even ever see the VLBW, arriving with the LBC reporting 2.2 kWh remaining on arrival, so I expect I would probably have seen the turtle after another 2.2 to 2.4 actual kWh use, a few miles past 120, had I continued on at about the same speed.

This~104 miles is as close as Google can map it, missing one short detour and the distances beyond the road.

https://www.google.com/maps/dir/39.7548 ... m1!1b1!3e0

Air temps from dash, ~92 F to ~102. Battery temps from LBC, averaging ~102 to ~104.

There are about 140 ft net descent driving North, and I believe I had slightly favorable light x winds.

Tire pressure ~44 to ~48 lbs, hot to hotter...

I drove below 45 mph the entire trip, and 33 to 35 mph most of the miles.

There are probably a dozen stoplights and three or four dozen stop signs (requiring 1.4 kWh of nominal regen) on this nearly-level route, over which I averaged ~30.4 mph overall, taking 3 hours and 26 minutes from start to stop.



Only three trips this year so far on my usual long-range VLBW capacity test route, but with close to 7,000 ft of ascent and descent on these trips, I won't make over 100 miles unless I drive beyond the VLBW, or until I get a new pack.

5/23/17

Carwings/Nissan connect: 12.8 kWh 93.5 miles, 7.3 m/kWh (identical to dash m/kWh display)

Actual: 14.3 kWh (est.) 95.7 miles (odometer) ~6.7 m/kWh (est.)

6/20/17

Carwings/Nissan connect: 12.8 kWh 95.2 miles, 7.4 m/kWh (identical to dash m/kWh display)

Actual: 14.3 kWh (est.) 97.4 miles (odometer) ~6.8 m/kWh (est.)
