Low battery warning not early enough

Sat Jun 25, 2011 2:55 pm

My low battery warning did not show up until I had 8 miles left. I had already gone 82 miles and expected that the low battery warning would show up at 20 miles left but it never did. Is this normal? I thought that low battery warnings should begin at 20 miles left and then at 8 miles it would say very low battery and direct me to a charging station. There were no charging stations, except for my home, within 8 miles when the low battery warning registered at 8 miles

How many bars did you have left at that point? Range is not a good way to determine when you have to charge.

This is normal with the new firmware.
The first warning appears as you are using your second last bar. Typically for me, the guessometer shows around 6-8 miles. The "very low" warning appears as your last bar disappears. The guessometer goes from 2-3 miles remaining to ---. Then you have a hidden reserve before you get to turtle.

There are charts describing this behavior in better detail. See http://www.mynissanleaf.com/viewtopic.php?f=31&t=4295

Be alert to whether posts refer to the original firmware or the new firmware (changed in April 2011)

My low warning usually shows up at around 11 miles left, which means at 38Mph I actually have 22 miles. Most of the time I'm in town, so I can get even more at a lesser speed. I much prefer the new to the old firmware. Tony did a great job with the SOC chart.

My warning starts when I turn on the car. The miles undulate a bit at first, then steadily drop as the miles driven continues. What else is needed?
I just pulled in with 9 miles remaining. No other warning needed.

The fact that you had no bars left didn't give you a clue that maybe you might be low on efuel?

It's no wonder Nissan changed the way they display range and SOC bars...

Dah, I absolutely knew I was low . I was experimenting to see when visual and audible warnings would occur. So that I could prepare a person who might borrow the Leaf as to whether they would have enough battery left to find a charging station when the car signaled that the battery was low. Given the lack of infrastructure, the warning system is of little use.

Take a look at the charts that I and others have posted here. It will give you all the particulars that you need. You can look in this thread: http://www.mynissanleaf.com/viewtopic.php?f=31&t=4295

The person borrowing the car should have plenty of warning from you that there are pretty much no random recharge places to just push a button to find and pull in.
They need to plan and pay attention.
