Power Charger

I set out on a walk through Frankfurt yesterday, and eventually came to see this odd stand next to a government building. It's a charging station for battery-powered cars.

The blue box is the power charger itself.  The silver-like box is a credit card acceptance device.

Basically, you pull up and park....paying your standard parking fee.  Then you hook up your charging cable to the blue box, and insert the credit card to pay for X amount of a charge.  It wasn't exactly clear how much the cost was.

Usage?  Well....it would be interesting to know in an average month how many folks pull up and use it.  It's the first one I've seen on the streets of Germany....most are rigged up at homes.....within a garage.
