No EVSE is "more powerful" than 16a when it comes to the Leaf. I don't see the point in a 20a unit. Either use the upgraded Nissan unit at 16a or get a permanent unit on a 40a line so you're "future-proofed" for charging MY2013+ Leafs or other EVs at 6.6kw. Or get the SPX for the best of both worlds, and for much less than Clipper Creek.

GE Wattstation
http://www.geindustrial.com/cwc/Dispatc ... -WallMount
Should be available soon at Lowes.com. Rumour is a couple stores have a few on display. Price $800????
Available in different colors. Seems bulky large and more profile at 6" deep.
Requires 40 amp circuit, has a nice holster. Outdoor rated. Cord is just 16'
Has an OFF mode to draw zero power when not in use.
The Wattstation is $999 at Lowe's. It's still not available at lowes.com even though promised to be there some time this month. They have about a week left to deliver. I use the on/off button all the time but, doh, you have to remember to turn it on when you plug in! Bought mine at the Burbank, CA, Lowe's on the first day it was available but apparently their inventory has been hit or miss since. It may be a large and bulky unit but is also the most attractive design of all the EVSE's imho. There are two models, hardwired and plugin. Ventura County only allows hardwired installation so we had to remove the plug from our plug in unit.

This helps tremendously. Seems to me that one of the key decisions is whether to get something capable of 30+amps to take advantage of potential improved onboard charger in the future, or stick with something less than 20amps for current model. Does anyone see the potential of a charger upgrade that could take advantage of 30-40 amps 240v?

It is my opinion that the 20 amp circuit (16a charging) will work fine for home use especially when charging overnight. Daytime charging to run errands during the day would be mostly adequate but there would probably be a periodic exception where you want a faster charge. I am on L1 driving average 50 miles a day and there have only been a few times in four months when I could not run that last errand due to L1 vs L2.

If you had a 150 mile range car and needed to run 125 miles in the morning and again in the afternoon then you absolutely will want 40+ amp circuit.

You can get close to 100 miles charged in the super off peak window from 12a to 6a.

Vehicles that charge faster will do much better at opportunity charging when on the road. Commercial charging seems to be 40 amp minimum(32a charging). Current Leaf is limited to 16a.

If you have 200 amp main panel at home you may as well put in 40a evse. Some have 100 to 160 amp panels and the electrician recommends an upgrade at additional cost. If this was the case I would go with 20a to avoid the main panel replacement.

I do not expect there to be any retrofit to put a larger charger into the existing Leaf.

The answer there is CHAdeMO... We just need the chargers to get installed where we need them.

The LCS-25 is nice if you can't spare 40/30 amps, like me. That would overload one phase of my service since it it is 3x63A. 20A will let me charge a future Leaf or Model S at 4.6kW.

I would suspect some US citzens with 100A service to also have problems with a 30/40A unit.

I do plan to upgrade my stock Nissan unit to 16A (10A standard over here) but have no wish to pack and unpack it all the time, hence a permanent EVSE.

As smkettner said, I doubt there will be any upgrade available anytime soon. And for regular home charging it's really unnecessary anyway. There may be some hope in an adapter/charger that can accept a higher-rated J1772 plug for a power source and charge at a faster rate via the QC port, but that would be very costly and bulky at this point.

Also, to be clear on the "30-40 amps" question, the "conventional" wall units are all capable of charging at 32 amps, but require a circuit rated at 40 amps for 25% margin. Similarly, the upgraded Nissan or appropriately-set SPX charge at 16a and require a 20a circuit, and the stock or upgraded Nissan unit charges at 12a on a 15a (120v) circuit. Note 25% margin in each case.

Which route you take will probably be dictated by what you have available in your home. If you already have a 20a or 30a outlet available in your garage then it would be very cheap and easy to just get the EVSEupgrade for the Nissan unit and be done with it, but if you have to (or want to) run a new line anyway then you might as well make it a 40a line, since the additional cost of larger wire and breaker is peanuts compared to the cost of your electrician's labor. Of course, if a 40a line means you need to upgrade your panel, that's another story...

Personally, I had my Nissan unit upgraded and I plug it in with a simple adapter to an old-style 30a dryer outlet in my garage, which was unused as I have a gas dryer. I also ordered a second Nissan unit to carry in the car and had it upgraded as well. Although with the cheap wall units showing up on ebay recently I might have gone that route instead of getting the second Nissan unit. FYI, if you search for "nissan leaf charger" on ebay there are currently both an AV and a Blink unit up from reputable sellers with bids <$500.

You call them up and say "I'd like to buy an EVSE on a cash-and-carry basis". Easy peasy.

Or you can just look at what has already been done at:

It's a reasonable place to start the search and then look at the many comments on this forum.
VERY nice find !!
I'd suggest it be made into a stickie ... but with 50,000 stickies already - it's gett'n kinda ridiculous.
