I use two EU2000's in series with a special circuit. This produces 240v, then I use an EVSE programmed for 13A. I can easily set an EVSE to any amperage I choose here in the Lab, but there is no easy way to make it adjustable in the field.

So, we just need you to whip me up a "special circuit" for two Hondas, and when you're done with that, I'll take a "Quick 240-100" for two RV campground NEMA 14-50's.

This generator produces 15kW and does 240v.

Much bigger than a Honda, and good luck fitting it in your Leaf! =)

We have Ballard Fuel Cell gensets which put out 10KW 220VAC 3-phase and 120 VAC at both 60 Hz and 400 Hz which are about the size of a foot locker. They ain't cheap but they make no noise. Great for Stealthy, sneaky folks who were never there, and you never saw them or heard them. I am thinking the GGSA price is about $40,000 and it runs on any re-formable product. Army is using with a JP8 fueled version too. Also, there are several sizes of a high pressure steam gen set out of Florida which the DoD has been buying up in truck-loads. Runs on anything liquid which will burn.

NOW, How much would you Pay?!? =)

It's always possible, but given the extremely low quantities such a device would be sold at, expect it to cost upwards of a quarter million to be worth making.

Honda couldn't even do it, so it's unlikely you'll ever see it unless you want to pay someone megabucks.

-Phil
OK but I can dream can't I? :-)

Is the EU2000 a US only product? (ironic since the name starts with "EU") If there was a European version that put out 240 you'd be one step closer, although maybe that doesn't help if the only option to consume less power on L2 is 10 amps.

I suppose if there were enough EVs out there to make such a product viable there would also be enough public charging around to make it unnecessary.

I'm sorry but I have to think that anyone would would need to use something like this generator scheme more than once a year or so would be better off with a Volt or equivalent.

I presume that there won't be any problems running a UK specification Honda EU2000 with the modified Panasonic at 230 volts, vice the USA 240v. The 50Hz versus 60Hz might be an issue, but Phol would know that answer.

But, the final issue is COST. In Pound Sterling, those things list for 1350. That's $1800-$2000 each. I can buy two of the USA spec 120v models for that price, and not pay import duties and IVA (20%) tax. Plus oversea shipping.

So, I'd prefer to stick with a cheaper generator that I can use here with normal 120v things, and also use to charge the car. So, if a kit comes out to modify them to run 240v, I would prefer that.

That's the ticket, only 1600 watts though, only a marginal improvement over L1.

The idea would be to use two, so you end up with a bit under 3.0kW continuous, while producing 230 volt, 14 amp (actually, it might only be 13 amp limit).

Both generators are "cheap"and light enough to easily handle and carry, and compatible with the modified EVSE at 12 amps and 230/240v.
