The majority of electric vehicles use less than $4 worth of electricity to charge (if totally depleted). As we see with the proliferation of free chargers all around the country, most businesses must feel that's a worthwhile expense to draw electric car customers (who are generally in the higher income bracket). For the foreseeable future, I expect the cost of the chargers will be spread out over all the customers through higher prices at the businesses that supply free charging. When electric cars become a larger share of the national fleet, this will probably change. Currently, business owners who think they will develop a revenue stream from electric car drivers are only going to see those customers gravitate to the competition that understands the value of attracting them with free chargers. Most people do not understand how much more efficient electric vehicles are and how cheap it is to charge them up.
