While 220V charging, a smart electricity grid, and J1772 standard
plugs are all good things...


I am not yet sold on how they could permeate the market appearing everywhere.

I mean if I am a store, or a property owner... I can go to home depot,
buy a metal pipe, attach a weatherproof plastic electrical box to it
with an outdoor rated NEMA 5-20 plug with GFCI... and now I have an
electric vehicle recharging station for less than $100 in materials.
Then I just need $63/year to pay for the electricity for that lone
plug.  ($63 for electricity presumes $0.015/kwh commercial rates,
charging at 15A, and using it continuously for 9hrs/day and
5days/week.)

Compare that $163 for a dumb plug to at least $2000 for a shiny new
J1772 smart charging station... and I'm unsure why I would opt for it.

To be fair... for $2000 the shiny new J1772 charging station should be
able to charge exorbitant amounts of money for electricity by
requiring a credit card or a cell phone... so I might could make money
off of such an endeavor, but I would need a lot of people charging to
make back that amount of money.  The cost for a dumb plug is so low as
to be a "why not do this to attract customers".
