Here's how bad the range can get with a seriously degraded battery:

Update: - 9 October 2012, Added chart version "7G". Each PDF file has English (first page) and Metric (second page) measure.
Now for iPhone, iPad, and iPod, free from the Apple App Store
Now for Android !!!

If your LEAF is missing any of the capacity bar segments of the 12 total capacity segments (number 14 in the photo above), use the appropriate chart:

Here are the links on Dropbox - no downloading hassle:

Use this 100% chart for a factory new battery.

Use this 93% chart for a one year old or more battery that still has all 12 capacity bar segments.

Use this 82% chart for a battery that has 11 of 12 capacity bar segments.

Use this 75% chart for a battery that has 10 of 12 capacity bar segments.

Use this 69% chart for a battery that has 9 of 12 capacity bar segments.

Use this 63% chart for a battery that has 8 of 12 capacity bar segments.

************************

EPA LA4 test cycle: 100 miles

The Nissan LEAF has been tested under the EPA Urban Dynamometer Driving Schedule, a laboratory test commonly called the LA4 test cycle, which represents city driving conditions. Top speed is 56.7 mph and average speed is 19.59 mph. Ambient temperature can vary from 68 - 86 degrees. Climate control is off. The Nissan LEAF easily achieved 100 miles.

************************


If you decide to use this chart, you can print it out and carry it in your car for reference. Your range may vary.

If you want an emailed PDF or the original Excel file, just PM with you email address, or probably easier for me, just email me at:

12 / 120 ------- Any ------ 4.0 miles (supplied cable with car in USA/Canada)
12 / 208 ------ Public ----- 8.4 miles (EVSEupgrade.com 2011/12 LEAF)
12 / 240 ------ Home ----- 9.6 miles (EVSEupgrade.com 2011/12 LEAF)
16 / 208 ------ Public ----- 11.1 miles (EVSEupgrade.com 2011/12 LEAF)****
16 / 240 ------ Home ----- 12.9 miles (EVSEupgrade.com 2011/12 LEAF)

30 / 208 ------ Public ----- 21.4 miles (unverified at 30 amps**)
30 / 240 ------ Home ----- 22.7 miles (limited to 27.5 amps)


**** will likely pull 18 amps at 208 volts****

**I don't know if its been measured at 200 or 208 volts yet to see if it increases to 30 amps.**

TIME USED CHARGING

Nissan LEAF hours to charge LEAF with warm new condition battery
From Turtle mode ("dead") to 100%

30 / 240 ------ Home ------ 4.2 hours (limited to 27.5 amps)

LEAF Charge-Rate Chart
Assumes 30 amp pilot signal from EVSE


----------- Japan --- USA/Canada - The World --- USA/Canada
Amps --- 200 volts --- 208 volts --- 230 volts ------- 240volts

16 -------- 3.2kW -------- 3.3kW ---- 3.7kW ------ 3.8kW
27.5 ------ 5.5kW** ------ 5.7kW** --- 6.3kW ------ 6.6kW


Obviously, the charger will output some value below those stated above, at about 85-90%. So, a typical LEAF drawing 16 amps at your North American house's 240 volts will put 3.3kW into the battery, and draw 3.8kW from the wall.

The new 2013 LEAF with optional 27.5 amp charger will be about 6.6kW at 240 volts. The 2013 LEAF-S retains the 16 amp charger of all previous LEAFs.

**I don't know if its been measured at 200 or 208 volts yet to see if it increases to 30 amps.**

Nice. I'll probably move this to its own thread.

Nice chart. Thanks. It might help all of us reduce any remaining anxiety ... :)

Now ... I know it's apples-to-oranges, at least in terms of price and range, but if Nissan could just get their engineering resources to produce something accurate to replace the guessometer ... with a more useful tool and data (look at the 2nd "-" paragraph): http://www.teslamotorsclub.com/showthre ... #post70188

Very nice graph. However, it's far too complicated for the average driver and, given the inability to accurately measure the output in kW, ultimately not that useful even for those who could understand it.

Interesting chart - the "projected battery discharge curve" and the actual battery discharge curve don't seem to be in great agreement. It would be interesting to know what caused the actual discharge to have the inverse curvature to the projected (looks like two spots where the curvatures are opposite), and see if there is a way to extend that actual discharge behavior. Is it just speed/load/discharge rate? Seems the graph is missing a critical axis of information.

Very nice! Any chance you could put this into a PDF link, it would be nice to have laminated in the car for my wife and I to help reinforce good speed habits and to give a decent way to predict range.

Doesn't seem like someone should be studying spreadsheets while driving.

I prefer the Ford mockup of the 'waterfall' range graph.

Great job! Might want to point out that this is with the latest firmware even though I am sure there only a handful of Leafs running the old firmware including mine.

Huh, far too complicated for the average driver? It's just a table. Are we assuming that the average driver can't read a simple table?

As long as Tony based his chart on reliable data, I think it's amazingly useful.
