Very interesting!
For the power level, it is a little pricey. If it was 3 kW, 120/240V you could power things like table saws for construction and it would still be fairly light. 6 kW would be nice, though it will be a bit heavier and bigger.
Mitsubishi Motors Corporation (MMC) announced today that it will bring to market on April 27 the new MiEV power BOX power feeder which is capable of supplying large amounts of electrical power from an electric vehicle (EV). Supplied by a Mitsubishi Group affiliate, the MiEV power BOX will be offered as a dealer option for the company's i-MiEV *1 and MINICAB-MiEV EVs.
So we don't know that it's compatible with the LEAF yet, they're using the ChaDeMO port but are they using standard protocol that's also supported by the LEAF, even so it needs to be tested for interoperability. They might be using something non-standard, either for convenience, oversight, or to intentional have it work only with the MiEV. Early Chevy Volts were J1772 but they didn't allow enough time for the portable Nissan EVSE to initialize, so you couldn't a Volt with it. Later Volts fixed this. The standard may not have been specific enough on this time period so you end up with twp compliant products that will not work together. Hence, this needs to be tested with a LEAF before we know for SURE that it is compatible with the LEAF.
It might be hard to get without ordering the car, they say you can order with the car, but make no mention if it will be available as a spare part or for order without the car.
Then you need the 120V 60Hz version for the American market. 100V can work for some applications instead of 120V but things like motors could overheat and not perform as well due to the lower voltage.
It would also be nice to know if this is modified sinewave or a true sinewave inverter. Motors and transformers overheat on modified sinewave inverters due to the excess harmonic power frequencies that end up as heat from the near-squarewave that marketroids have called "Modified Sinewave".
Still very interesting. I'll be watching for more information as it comes! Might consider getting one, but the Nissan's "LEAF to Home" is 6 kW via the ChaDeMO port and more versatile, though it's not something you can carry with one hand! http://www.mynissanleaf.com/viewtopic.php?f=6&t=6619" onclick="window.open(this.href);return false;
