Nissan will between now and next April install quick chargers for its Leaf electric car at more than 100 dealerships in 21 cities around the country. The units will be able to charge an empty battery to 80 percent capacity in half an hour. A company spokesman said the list of dealerships that will get quick chargers hasn't been finalized, but Nashville is set to get some. Middle Tennessee is the No. 7 market in the country in Leaf sales. Through the first half of this year, Nissan sold 9,839 models in the U.S., more than in all of 2012.
