90% charge needed.

Or user programmable level. I live on a hill. I never want to charge to 100%. I charge to 80%, but if I need extended range, I have to interrupt charging, otherwise I have no regen.
Also, I'd like to request GPS location via Carwings.

Oh, I have added a Level 2 (11.5KW) 24/7 free charger. It's located in Sequim, WA. Just search J1772 Sequim.

You know, it just occurred to me. There might be another advantage to this. Nissan should just offer the driver the option to charge to any SOC in increments of 5% or 10%. How would this affect the EPA range rating. Right now some vehicles such as the Spark EV are showing a higher EPA range rating because they don't have a long-life battery mode. So if Nissan were to just change it to offer any charge limit the driver wanted to impose, it would be hard for the EPA to make the case that a specific level is what should be tested.

Hear, hear! I like the 50 - 100% "slider" in the Tesla S!

I agree, I would like more control of this as well, especially via Carwings. Having to get back in the car and turn it on just to change a simple setting is really annoying.

I find that one way to get a 90% charge is by pre-conditioning the cabin. Set the charge timer to 80% and then either use Carwings or the climate control timer to run the heater/air-conditioner. The car will charge using the power it is not drawing for the climate control. Side benefits, actually the intended primary benefits, are a comfy cabin and less power draw from the battery at the start of a drive.

Please note, this works fine for me in Phoenix, where we use our A/C early and often.

"100%" is actually closer to 90% than you think. Just do an end-timer to "100%", you'll be fine.

You missed the point - 100% charge = no regen and the OP lives on a hill.

The most convenient ways I can think of to get ~90%:

1. Set a 100% end time only timer about 1 hour after your departure time. Takes some trial and error and there is some variability in the actual end time.
2. Manually charge for 30 minutes after a 80% charge by hitting timer override. But you have to set your own timer to remember to go unplug.

Would also be nice because we don't always get the charge we asked for.
Set to charge to 80% but it got there early and sat for 15 hours. When we got in the car, it reported only 76% charge. Quite a difference from 100%. If we're not sure of the range we get, we're more likely to choose 100%.

Was this SOC readout from Jim's Android app?

Your method 2 is more reliable and repeatable; I use that one, right down to setting a kitchen timer. Simple, easy, reliable.

The problem with method 1 is that the end-time can be highly variable. Especially if you also preheat: it finishes an additional hour or so early when you have the climate control timer(s) set. The variability of end-time-only charging would make trying to hit a 90% charge target quite frustrating, I would think.
