Re: new owner - am I doing something wrong?

Here's a chart from another thread that might be helpful to you... This is based on the "NEW" software and is not valid for any cars still running the old software.

Speed in MPH......38....50...60....70...Battery Value and percent battery remaining
Battery Warning...20...14...12....10....48...17.00%
Very Low Warn....10.....7....6.......5.....24.....8.50%
Turtle mode........about 1 mile..........5......1.70
Interesting...I received the 'low battery' warning (fuel icon) at 11 miles and one bar remaining going around 38mph not 70mph. Maybe that was because I was getting 5.5m/kwh?

Stop using the guess0meter !!!! Rely on the fuel bars, and when you're down to zero fuel bars, use the data points I provided with first the Battery and then Very Low warnings. Reset your trip odometer as soon as you get one of those warnings and look on the chart to determine your range.

You are missing the point if you are using your "guess o meter" to indicate that you have 11 miles. As has been stated numerous times, those numbers are NOT ACCURATE. If you were going 38mph on relatively flat highway, you've got 20-22 miles to go.

The chart I provided will give you the range based on the ACTUAL numeric value of power left in the battery (I included the raw data values in bold; 48, 24, 5) and the calculated remaining power remaining. The remaining calculation is the miles per kilowatt, roughly 10 miles per kilowatt at 38mph, reducing to 5 miles per kilowatt at 70mph.

DON'T USE CARWINGS, YOUR iPHONE, or the DASH GUESSOMETER to figure range.

Cover the guess0meter up !!!!

Oh, so you are saying that I actually had 20 miles left when I was down to one bar and saw the low fuel icon?

YES !!! I edited my previous post to address that.

Use the chart that is posted by Mogur. It's useless to debate the guessOmeter numbers.

If you have questions on the chart, I'll answer those.

And this one is useful for what exactly? Certainly not for general use. Or do we get different charts for different temperature bands and different wind conditions and different terrain, all revised on a yearly basis to reflect battery pack degradation?

Your suggesting a precision that doesn't exist. Too many variables are unaccounted for.

And yet it turns my experience from an alarming bit of bad range to well within expectations. Based on the new chart, I was getting mid-60's total range before.

Incidentally, today I drove from 80% to 2 bars over the course of 45 miles. That would be scary using the original scale (since it would work out to 70 miles total range and I drove REALLY conservatively today), but using the chart I see that there's actually 34% of the battery remaining, so I used 46% to go 45 miles - total range estimate just a tad below 100 - Which sounds GREAT to me.

As a note, I'm now seeing 4.5 mpk range most of the time, so I'm getting better :)

Again, thanks for the chart - quick question, is that from one of the service manuals or something? Or was it user created based on experiences here?

I've suggested, more than once, of the many variables that are not accounted for. Obviously, you chose to overlook that. If the chart doesn't work for you, don't use it. For new owners, it's a good guideline.

The chart was developed using battery data derived from our crack team of hackers, driving experience, and a need for SIMPLICITY in deriving a predicted range.

There will always be somebody who "didn't get this or that range number". Great. I think you'll find it quite handy as you learn the ropes of the LEAF.
