I think that this only further proves my point. It is ridiculous to have to play a guessing game in order to regain functionality that was included in the first model of the Leaf.

Nissan: please consider implementing one of the solutions I suggested in my original post.

Bonus points for implementing an option where you input the Start Time and the desired % at which you wish charging to end (in this fashion my car would start charging at 3am, long after I've finished driving, and will stop at 70 or 90% or whatever % I set by the time I want to drive the car at 5:50am - 6:20am. [This assumes of course that I've left adequate time between the Start time and % I desire to be charged.]).


I've actually gotten to the point where I just go plug it in the moment I wake up and then take my shower, eat breakfast, etc... when I'm ready to leave, I've gotten the extra % I need. The tough part is when my wife drives it to work (free chargers at Apple) and I tell her to not charge to 100% and let it sit. The charge timer is cumbersome on the S model, so I tell her to disable the timer, look at her % charge, figure 35% per hour on the L2 and set a timer on her phone to go out and unplug. She always forgets though and the car sits at 100%. I normally wouldn't care so much, but we bought, not leased, so its our battery in the end.

Maybe you should find out where the charge is usually when she arrives, set a timer yourself, and call her. You can always er, charge her for the service. ;-)

With and S model without carwings, I can't set one remotely for her. What I've been doing is guestimating a stop time in the morning. For example, I set it to stop at 10:30 this morning knowing that she will get there just before 9:00 with approx. 30% charge. Usually I'm accurate enough for it to land between 80-90% when its done.

Part of me wishes I got the SV, but they wrap the QC into yet another package with the SV so you wind up spending another $2K more for really only two features that I cared about (heater and more charge functionality). I'd rather save the $2K for a replacement battery in 4-5 years.

I have contacted Nissan on three different occasions inquiring about the possible damage to the battery on overcharging(past 80%). Each time, the rep stated that with the new Lizard batteries, there is absolutely no harm to the battery with frequent 100% top off. It is reassuring to hear that consistently, but only time will tell if this is true.

As we live on a mountain range, I've long wanted Nissan to implement an adjustable charge "slider". 80% has always been too high for decent regen if descending the 4900' (1500m) to the base of our mountain.

With our degraded 2011 battery and our average mountain temperatures, the SOC would need to be pretty low to get good regen. This is a major reason that our LEAF is now used only rarely for trips off the mountain (charging is required to come back up if the SOC was low going down, riding the brakes at high SOC is problematic, and the nearest quick charger stops with less charge than needed). Thankfully, it's still a great car for driving between our mountain communities (ranging from Crestline, CA to Big Bear, CA).

I too would like to be able to set a charging limit. Preferably in 5% increments. I live at the top of a hill and can easily regenerate 2% SOC but only if the battery isn't fully charged. Between 80% and 90% I can regen a full 30 kW in B-mode and never have to brake during the descent and never exceed the speed limit. It's a real joy to recover all of that potential energy! Above 90% I regen 10 kW and if fully charged I'm riding the brakes. And I'd really like to save the wear and tear on them. I spent a lot of money replacing pads and rotors on my ICE vehicles.

The charging timers are too cumbersome. I've forgotten to turn them off and failed to charge. Unless I drive exactly the same number of kilometers each day the timer can under or over charge unless I keep resetting the timer duration.

My 2015 european Leaf, has the Long-Distance mode. In the carwings menu, i can put it on 80% charge max. Is this what you need???

Do you not shift into a lower gear and use compression braking coming down the hill? That's what they're there for.

Yes. In the US, the rated range of the car was lowered to reflect a 90% charge (average of 100% and 80%) because the car had 80% mode...so Nissan removed it. Tesla has been able to get away with a slider without a problem, but Nissan chooses to just take away the capability altogether.

Of course, their comments are all suspect since they removed the 80% timer long before the Lizard battery came out simply to game the EPA...
