US electric car maker Tesla announced on Thursday that it will establish seven supercharging networks in major cities and popular travel destinations in the second half of this year.Tesla has its second largest charging network in China -- second only to the United States -- with hundreds of public charging posts and more than 1,300 commercial ones already in operation across China.

The new charging stations will be in the Yangtze River Delta, Beijing-Tianjin-Hebei region and at east China's Mount Huangshan, a UNESCO World Natural Heritage site.

Tesla superchargers, jointly powered by grid electricity and solar energy, can charge Tesla Model S in minutes instead of hours.
