That's pretty optimistic thinking. You have to take into account how
long a driver is willing to wait for a charger to become available. I
would guess in the *best* of circumstances that would result in a 50%
occupancy rate. But of course some times of day would be in more or less
demand than others.
Another factor is that some of the time is the user authorizing his
account, plugging in the cable, and unplugging and moving the car when
done. You don't get revenue during those times.
Third, if someone goes past about 80% charge, the trickle charge should
start and you get substantially less revenue.
I believe anyone who installs an L3 should expect it to be a loss and
plan on recouping it with associated business.

If there were a car plugged into all three for 10 hours a day that would be
$160 to $175 at $0.20 per KWh. Assuming cost of $0.10 a KWh that would take two
years to get back the investment with no maintenance costs.
Those are big if's..... but then it would be $25k a year income. I've never
seen chargers that busy around here but maybe in California.

Locally (Menomonie, WI, about an hour east of St Paul, MN) our food co-op and
an electric car owner/investor are hoping to install two level 2 and a 75kW
level 3 charging stations at the co-op storefront location. They are figuring
on about $50,000 by the time it is functional (most of the cost due to the
level 3 charging). I'm not sure how payment for charging will be done, but I
thought that the total estimated cost that they are assuming was interesting.
