Electric car chargers installed on Beijing-Shanghai expressway

The construction of electric vehicle charging stations along the 1,262-km expressway that links Beijing and Shanghai finished on Thursday.

State Grid, one of China's two grid corporations, built 50 quick-charging stations along the route, making it the country's first cross-city charging network.

Each of the stations has eight charging poles capable of fully charging an electric car in 30 minutes. All electric cars that meet Chinese standards can use the charging facilities.

State Grid built 133 quick-charging stations with 532 charging poles along three major expressways with total length of 2,900 km in 2014.

The company aims to build charging station networks along eight major expressways with total length of 19,000 km in China by 2020.

Electric vehicles are gaining popularity in China amid its "green" drive, but buyers are hesitant as they worry about a lack of charging stations.
