Assuming you only recently bought your iMiEV, might I suggest you drive it for a while before you decide you need to make a major modification - Are you charging using L2 all the time . . . . because plugging it into any 120 volt outlet isn't using all of the car's capability
You may find, as many of us have, that it works pretty darned well just the way it is. If you need to go 125 miles in one trip so that the car's built in L2 240 volt 3.3Kw charging capacity is really slowing you down, maybe you bought the wrong car??
