As jjeff said, I'm in Malta, which uses the UK system. 50Hz 240V AC, standard plugs are fitted with 13A fuse giving a max theoretical power of around 3.2kW. So anything 110V or American-spec wouldn't apply this side of the pond.
I saw the model S allowing charge rate to be varied from the touchscreen on a YouTube video - someone was charging it with a portable 2kW (actually 1.6kW) honda eu2000i generator. That's pretty neat. It's nice to know the i3 does that as well. I'm surprised the leaf doesn't. Problem with the i3, and in fact most EVs is cost. A Renault Zoe in Malta costs €35k new (if you buy the battery outright). For that price I can buy three Ford Ka's!
I thought of buying a cheap used leaf in the UK and driving it down to Malta, but my calculations show it will need recharging a minimum of 17 times over the distance of the trip. That's why I need some sort of backup in case I find charging stations broken or occupied. Course I could have it shipped to Malta directly for €950 like I did with my last car, but where's the fun in that?
Oh, before I forget, some background since this is my first thread on the forum. I'm a warranted mechanical engineer, though I spent the first few years of my career programming robots and doing R&D in a semiconductor factory (that among other things makes the gyros, accelerometers, microphones and other sensors in many well-known smartphone brands). I'm well-versed with electrical theory (up to and including 3-phase AC theory). I'm also an RC car and helicopter hobbyist, which is where I learnt to put theory into practice. Electric cars are after all a scaled-up version of the systems in a hobby-grade RC car (though the RC ones use DC brushless motors driven by a rudimentary ESC whereas most full size EVs seem to prefer induction motors driven by a full-fledged VFD).
When I charge a battery, I normally do it using a dedicated charger directly connected to the battery terminals, setting appropriate voltage and current limits. Seems EVs add an extra level of obfuscation to the process to make it fool-proof to the majority of drivers, who simply want to plug in a wire that magically tells the car how much power it can draw, without having to set it themselves.
Unfortunately this means that in unique situations like mine with the 1kw generator, it becomes a bit tricky to get the desired behaviour from the car because I'd have to know how the charging standards work - i.e. what signals or voltages to send to which pins to tell it to limit itself to 4A at 240V. Well, either that, or spend €300 on the appropriate cable, which essentially consists of a few plugs, some copper wire, and some circuitry that could probably be mimicked by an Arduino board costing a few dollars.
It's made worse by the fact that there isn't a single universal standard that applies to all electric cars, each car only supports a subset of them, and sometimes it even varies by model year for the same car (look at the Renault Zoe for instance, the early model years were hopelessly inefficient at charging from wall sockets, the later years sacrificed super high power charging for more efficient low-power house socket charging).
