WASHINGTON, September 13, 2017 - Electric vehicle (EV) manufacturer Tesla is aiming to broaden its customer base by improving accessibility to the brand’s superchargers. While EV batteries typically are charged overnight, the supercharger delivers a rapid 72 kilowatts of dedicated power to each car, allowing for consistent charging times around 45 to 50 minutes. In addition to a growing network of superchargers along highways, workplaces and destinations like hotels, Tesla is expanding the network into city centers, starting with downtown Chicago and Boston.
