Totally can't come to terms with the whole idea of a "home charging station". What's the rationale behind such an expensive junk :lol: box. I plug my Vectrix twice daily into an ordinary wall socket. What on earth for would I have to install a special box in my garage for a Nissan Leaf? Would I have to install another box for a VW E-up? I sincerely hope that I'm not limited to charge a Nissan Leaf only at its own proprietary Nissan "charging stations", but will be able, in the future, to connect my on-board charger to the existing ubiquitous electric "infrastructure", constituted by the world-spanning electric grid, for opportunity charging. Hard to believe that US National Electric Code requires expensive "charging stations" without any added functionality, to control charging in homes of private citizens. It might once become brisk business for the likes of Coulomb, Schneider Electric, Blink, General Electric, Aeronvironment, to sell and install those futile boxes. I've heard rumblings that like European guidelines are being brewed up in Brussels.
However, "connectivity" for me is a standard European wall socket, be it of the single phase 230 V, or the CEE 3 × 400V/230V/16 A, or /32A variety (yes that's a 22 kW connector, not quite uncommon in work shops or farms).
No need even for any fancy new 7-pole "Mennekes"
http://en.wikipedia.org/wiki/IEC_62196 plugs, which -- because unavailable and not yet officially standardized -- prevent me and all the fellow EV drivers from using those new public charging columns here in Carinthia. I will admit as much as there should be some kind of identification/roaming provisions at public points, but no need for "connectivity" to obstruct plugging-in at my home.
