I've tried to drill into this with Nissan when one of their reps made the follow up call after purchase to see how I was liking the car. The woman on the phone took careful notes of the nuances of my questions and said she would find someone who really knew the answers. A few days later she called back and said there is nothing wrong with charging on L1, as in no known issues with it and that the primary reason Nissan is taking the stance that it is to be avoided is that it's just not practical for most people. I can certainly see that the primary PR issue with EV's is range and that Nissan would want to avoid popularizing the 21 hour charger... some, probably many people would hear that and feel that their worst fears were confirmed and not give it another consideration. The first hurdle, IMHO, in getting EV's into the mainstream is overcoming skepticism about charging and the batteries.
I believe it's a PR thing, and after trying to rely on L1 initially, and later getting L2, I can completely understand why they have taken this stance. While L1 charging is doable, planning for that occasional longish trip gets really tedious, especially if trying to go with 80% charging. I was starting to plan multiple opportunity charges ahead, adding up total number of hours charging in a 24 hour period. That's going to be a no-go for most of the public. All they need is to have someone's story about how proud they are of their complex charging regime get publicized and it will hurt public impression even more.
When my L2 finally got installed, I quickly found a convenient routine that covered the vast majority of my needs without having to think about it much. I set the timer to 80% and charge whenever possible, making it so that I almost always have an 80% charge and I'm a short top off to 100% on the rare occasion that I need it. I believe that this is the way the car and charging system is intended to be used because it is a way that will meeting the needs of the masses.
If you need to rely solely on L1, just know it can be tricky depending on how many miles you drive and your charging opportunities.

Have them show you anywhere where it says that in writing from Nissan. They won't be able to because it is not true. The only negative thing that Nissan has to say about L1 charging at all is that it is slower and less efficient than L2. It does not cause any "problems" of any kind.
I think it is simply a poor Japanese translation and that "emergency" refers to the time that it takes to charge on 120, which may be too long for some and their usage needs...

I also wonder. I'm a prospective buyer and don't plan on getting a home EVSE installed (long story). L1 charging will suffice for me (yes, I know it's very slow). If I end up buying, I wonder if I'll also get a "scolding". Hope Nissan's willing to elaborate on the "problems".
FWIW, in Japan, their power is only 100 volts out of the wall (http://www.jnto.go.jp/eng/arrange/essen ... icity.html
). Not sure of the amperage of typical 100 volt outlets household outlets there...
