Braking from Neutral for Range Maximizing, 2011 Leaf

Wed Jan 17, 2018 2:50 pm

I find if I switch the leaf to neutral (by holding the shift paddle left for a few seconds) I can coast really well, and save a lot of battery.
The problem comes when needing to brake, as it appears the regeneration does not work. I have to shift the paddle back to drive mode, then brake.

Is there a better way to do this?

so you are doing this because we can't turn off regen triggering when we let off pedal but we'd like it back when we are on the brakes?

I think this a question a lot of people have asked and wondered about before. I was hoping that the guy who created LeafSpy Pro would be able to figure it out and allow us to switch it off and on but I don't think he's found it yet, or at least, willing to risk sharing it.

We need a device like the Original Honda Insight had available through 3rd parties were you could control the amount of regen and power going to and from the battery while driving. I guess the nissan system is more closed that the Honda one?

I do this all the time. Coasting works great to increase my efficiency. I'll shift into N to coast, then D,D/Eco,B,B/Eco to maximize my regen in the space I need to stop. Barely use the brakes myself. Coming from a manual transmission, this constant shifting is very natural for me.

I would do that too but i have a SL with the screen showing the pie chart and I manage my regen with the pedal but I don't have a B mode.. mine is a 2012 so I don't have that. Maybe I can try coasting with N and see what it's like. having a hand movement is better than looking at a screen. It's not a new concept to me but my OCD wasn't strong enough for me to bother with this method..

Unless you are willing to pop back and forth between N and D, you're not going to realize any savings if you frequently brake while in N. Also, you'll wear your brake pads out faster. Either give up on neutral coasting, or get used to frequently switching between N and D. BTW, ECO mode does more regen, so you can use that too...

I would assume that someone who is goofy enough to shift into N while driving probably knows about ECO mode (and even B mode in newer models) giving more regen , but it always good to ask and share.

They just want a way to switch off regen unless braking, that is what I got from the OP question. I don't know of a way to do that.

Neutral mode by definition turns the motor off (even though it stays engaged with the axles) so this would require a whole new mode. "BN"? "NB"?

Geez... I'm starting to believe that no "mode", control, or gauge on the Leaf is good enough.....

I wonder how many people in the world are trying to invent a better wheel... :) :lol: :lol:

What I do is:

  • Switch to N mode when I see for example a red light ahead, or a long stretch of gentle downhill.
  • Switch to D then ECO (click twice) to start slowing down.
  • Finish off with a gentle braking operation with the brake pedal.

But if I need to brake quickly while in N, I know it will hit the friction brakes. That's what I'd like to avoid. I don't see why regen won't work when in N mode.
