If you're driving up a mountain and hit turtle mode what happens after you turn around and start regenerating downhill? Will the car come out of it or does it need to be plugged back in before that happens?
I don't think that the car will let you engage anything but neutral if you have killed it in turtle mode. It won't recharge in neutral at all, only coast. The chances of coming out of turtle mode without killing the car are low, since only a tiny amount of energy is available before the battery contractor drops. I wouldn't plan on arriving at the top of a mountain in turtle mode, that's cutting it way too close.michapok said:If you're driving up a mountain and hit turtle mode what happens after you turn around and start regenerating downhill?

I don't know; but I'm not gonna try it either. :!:michapok said:If you're driving up a mountain and hit turtle mode what happens after you turn around and start regenerating downhill? Will the car come out it or does it need to be plugged back in before that happens?
TonyWilliams said:What a timely topic. I have never successfully done this, or tried to do this in a LEAF. But, tonight, after 144.4 miles driven at 3.7 miles per kWh, I hit turtle mode in the Rav4 EV. I was about 2 miles from the charge station, which was about at a 300-500 foot lower elevation.
It will be in drive when you reach turtle mode, but you will have very little energy to play with until the battery contractor drops. It's not a good idea to let the contractor drop, because the car won't go into drive anymore, and it will take a while to recover from this state, just like Gerry described above. Whether the car will go out of turtle mode on the way down will depend on how much energy you can recover and put back into the battery. This might require an elevation drop of 500 feet or more and a relatively steep slope. Why do you need to know this?michapok said:Hmm, any consensus then? Will the Leaf behave like the Rav4 and come out? I've never gone down to turtle mode but I thought that it would still be in drive, not neutral.
michapok said:Originally I was going to rent a Leaf on vacation and see if I could make it to the top of an 7,500ft mountain. It's mostly a 8-10% grade up the entire way so regen the entire way down wouldn't be a problem. So, I wanted to see if I had to turn around at VLBW or could I go all the way to turtle. Now though, I did more research and for the trips I'll be making the Leaf won't work so that experiment has turned to a purely thought one. Still pretty curious though..
I think you can make it all the way from Kula. I would check the available stored energy in the battery with a Gid meter and conserve energy. About half of the usable battery capacity is needed to lift the car from 2,000 to 10,000 feet elevation. I remember watching this video a while a ago. It looks like the owner was down to one bar, but didn't see a low battery warning:michapok said:On Maui, Starting from Kula @2,500ft (plugshare member) up to the top of Haleakala @10,000ft. Here's a google map route: http://goo.gl/maps/LlPZ4" onclick="window.open(this.href);return false;
It's basically straight up at a 10% grade the entire way. I've heard of people doing it but I think they charged at the entrance to the park which is at 7,000ft.
michapok said:Dave, not sure what you mean by leaf being dead - I had planned on driving as far up the mountain as I could (hopefully to the top), but turning around when I got to either VLBW or if possible go a little further until I hit the reduced power (turtle) mode. At whichever of those points I would turn around immediately and drive back down, getting back to maybe 30% SOC by the time I descended the entire 7,5000ft (or maybe even 10,000ft if I went all the way to sea level).
I think given the steep continous grade and the results reported by Liam, this plan would have worked. I would turn around the moment I hit turtle, probably even sooner. Would consider a Gid meter a must, especially with a LEAF that has lost a bar. Speaking of which, could you tell us more? Mileage and age would be quite interesting. First LEAF with a missing bar reported from Hawaii. Although it's been predicted, no instances of bar loss were reported on this board.michapok said:Dave, not sure what you mean by leaf being dead - I had planned on driving as far up the mountain as I could (hopefully to the top), but turning around when I got to either VLBW or if possible go a little further until I hit the reduced power (turtle) mode.

This was all discussed upthread already.DaveinOlyWA said:Turtle mode still allows regen. if the power drops low enough, the pack will be disconnected and regen wont be an option which is what i thought you were originally talking about.
Shaun, are you still here? http://www.mynissanleaf.com/viewtopic.php?f=24&t=8949&hilit=maui#p200252michapok said:The rental car I would have gotten was had already lost a bar of capacity (2011 model) so it sounds like it would have been really close. I know Maui is way out ahead on quickcharge stations so maybe in a few years they'll have one or two on the way up. Oh well, would have been fun to try on a single charge.
