See specs tab of http://nissannews.com/en-US/nissan/usa/ ... -press-kit.

CHAdeMO inlet is to the left of the J1772 inlet. It's not on top.

These may help

No. The "level" terminology relates only to the voltage. Level 1 = 120V, Level 2 = 240V.

Typical home outlets are 120V, 15A circuits. But your 120V, 30A outlet would still be level 1.

I have tried the Leaf's internal charger and it only cares about current. I have only tried my enhanced charger but it is likely the basic charger is similar. An electric car's EVSE is considered continuous load o you are limited to 80% of the circuit. For a 30A 120V circuit you are limited to 24A.

Over 16A (80% of 20A) violates the J1772 L1 spec but it works fine. The stock EVSE signals the car that 12A is available (80% of a common 15A plug) There is really no way to change it. Some aftermarket evse's can be set for more.

We have a member that regularly charges at 120V and high current. Even 16A @ 240VAC is faster but you use what is available.

You might look into rewiring the circuit for 240V and changing the receptacle. a 14-50 socket is the unofficial standard. In this case the neutral is ignored. Many homes hare a 30A dryer receptacle. It currently uses a very similar plug. In fact only the neutral differs. Early homes use a 3 wire plug with no ground. Since it is not used some cut the pin flush so they can plug into 30, 50, and 60A outlets. For 40A circuit a 50A unit is used since there is no 40A parts.

Well I was just told on FB that my model S can only handle 16A and anything else is useless. does that mean im stuck with 15 to 20 hr charge times?

I was going to do install a 40A 220-240V but not if its not going to do anything and I went to look at newer models and it doesnt say charging capabilities.

Leaf S has a 3.3kW charger. You should be able to go from dry to almost full in 6 hours, with a 240V 16A station.

I am simplifying this a bit but if your car is the 3.3 you can charge up to 16 amps at 240 volts. The stock EVSE, sometimes called the portable EVSE or the trickle charger, that plugs in to a standard 120v volt outlet will supply 120 volts at 12 amps or 1440 watts to the car. The most important part here is the watts delivered to the car, both the voltage and amperage play in to those numbers. So now if you can up that, still at 120 volts to 16 amps you are now supplying the car 1920 watts. Now if you can get a 240 volt outlet that can supply 16 amps you can supply the car with 3840 watts.

Another way to think of the voltage of 120 volt vs 240 volt is one hose or two. So if they are both running at 16 amps 240 volts is twice as much as a single 120 volt hose, bad analogy I know, but maybe it helps.

120 volts at 12 amps = 1400 watts
120 volts at 16 amps = 1920 watts
240 volts at 16 amps = 3840 watts

Think of watts is how much power is moving at a time in to the car.

So you can see the 240 volt at 16 amps will charge much faster than 120 volts at 12 amps.

Another possibility, if you are feeling adventurous, is to upgrade the OBC:

Doesn't sound too difficult, but really only worth it if you can get the replacement OBC at a reasonable price (list price new is just under $1000, pretty steep)
