Re: Clarify:The LEAF uses a cellular-type network

Just one WiFi at each location, not at each charger.
And, not even absolutely required there, as data can be collected and sent later.

Also, the charging location probably already has Internet (or other "remote" access), to process credit cards and report in real time how many charging stations are available (and in service).

Even better, it could report the estimated time until a station is available, if somebody had designed the system correctly.

garygid, they may already have that or something similar planned, as on the "EV Project" Website, when you check a charging location, it tells you the # of chargers at the location and how many are in use/available (also on the Leaf telematic screen I think I saw the same thing on a demo I saw somewhere), of course they could be doing that via the same cellular network. I just think WiFi makes more sense these days, than a cell type network, no subscription fee is needed, the end user pays for the WiFi/Internet connection at their home, and at the public/commercial charging stations, the cost is amortized/bundled into the cost of the power billed to the user...

might have seen it on this demo: http://www.theevproject.com/portal/
