The city of Shenzhen bordering Hong Kong recently announced its technical standards for charging systems for electric vehicles, the first of its kind in China, according to a report in Guangdong Daily.
Wu Delin, vice chairman of the Shenzhen Municipal Reform and Development Commission, was quoted as saying that charging poles will become standard facilities in new residential buildings in the city.
Nine technical standards
Shenzhen Municipal Technical Standards for Electric Vehicle Charging Systems, according to Wu Delin, consists of nine standards. These are: General Requirements, Design Standards for Charging Stations and Charging Poles, Non-on-Board Charger, On-Board Charger, Charging Pole, Charging Station Monitoring and Management System, Communications Protocol for Non-on-Board Charger Control Unit and Battery Management System, Charging Connector for Non-on-Board Charger, and Charging Station for the Electric Bus.
“With these standards, we now have guidelines for the construction of charging facilities,” Wu says. “Shenzhe’s standards have reference value for the nation and other localities.”
¥60 billion in annual sales of new energy vehicles in Shenzhen
Information released at the press conference where the technical standards were announced shows that, by 2012, new energy vehicles are expected to reach 24,000 units in Shenzhen, to be found in three major areas: public transportation (including taxi service), institutional use and home use. These will include 4,000 buses (3,000 hybrid buses and 1,000 pure electric buses), 2,500 taxicabs, 2,500 institutional cars and 15,000 private cars. Shenzhen by then will have become a pilot city for the demonstration of both production and utilization of new energy vehicles, Wu Delin says.
By 2012, with 24,000 new energy vehicles on the road, the city can annually save 109,000 tons of gasoline and diesel worth ¥580 million ($85.3 million), according to Wu Delin. Benefits also include reduced discharges of 146,000 tons of carbon dioxide and of 1,026 tons of monoxide annually, Wu says.
Shenzhe’s new energy vehicle industry is going to be of considerable size by 2012. “By then, according to a preliminary estimate, Shenzhe’s new energy auto industry can have annual sales of more than ¥60 billion,” Wu says. By then the city’s two leading automakers, Wuzhoulong Motors Co. and BYD Auto Co., are expected to have new energy vehicle production capacities of 15,000 units and 200,000 units respectively, according to Wu.
Charging stations and poles
Different sites will be selected for charging stations and poles serving buses, institutional vehicles and private cars.
The city plans to build 25 slow-charge and quick-charge stations for new energy buses. Six charging stations have been built and put to use so far. These can basically meet charging demand from 850 new energy buses current in use. Of the 19 planned charging stations, 13 are under construction. Sites for the remaining six have been selected and their construction will start soon.
By 2012, Shenzhen will have built 2,500 slow-charge poles for institutional cars, 10,000 public slow-charge poles and close to 200 public quick-charge poles.
Additionally, Wu says, quick-charge poles will be built in the parking lots of public transportation companies and taxi operators. Also additionally, quick-charge poles will be built around government premises.
Charging poles to become standard facility of new residential estates
“The private car is the focus of new energy vehicle popularization,” Wu Delin says. Shenzhen will additionally build charging stations and charging poles in residential areas, in the parking lots of hotels and around transportation hubs so that they form a charging network. “Charging poles will be standard facility in new residential buildings,” Wu says.
