"Shop while you charge" may be an advertisement for a store near you according to some analysts in the industry. While there are only "1,400 publicly accessible chargers scattered around the country, Pike Research projects 13,000 stations by the end of 2012."
Depending on where they are located, that should be more than enough to satisfy the "fewer than 15,000 all-electric cars on U.S. roads today according to Plug In America, a group promoting the technology."
Many if not most analysts doubt that number will not explode to the one million that President Obama hopes for 2015. Regardless, small and chain businesses, like Walgreens have shown interest in ordering the chargers, in part because of a federal government subsidy of "$130 million for two pilot projects that help pay for chargers at homes, offices and public locations."
"A 480-volt 'fast' charger, capable of recharging a vehicle in 30 minutes or less, typically costs $40,000, plus installation. The more common commercial 240-volt chargers... can cost $2,000 to $3,000 and take almost eight hours to fully charge a Nissan Leaf, though they offer a meaningful boost in shorter periods.
Home chargers can cost $700 to $1,000, plus at least that much for installation. Those costs will fall as production rises, says John Gartner, an analyst at Pike Research."
