BEIJING-Shanghai high-speed electric vehicle fast-charging network today

Driving electric cars can also go home for the new year. 15th, the Beijing-Shanghai high-speed network will be fully connected (that is, the whole process into use), become the first electric vehicle with fast charging service function of the expressway.

Electric vehicle charge lower than petrol car fuel charge

14th, the National Grid launched by the electric car "Beijing-Shanghai Line" team in Beijing to hold the finishing ceremony. Convoy January 10 from Shanghai Jia Ding Pavilion Express station, the way to Shanghai, Jiangsu, Shandong, Hebei, Tianjin, Beijing and other six provinces and cities along the route 27 fast filling station, lasted 4 days to complete.

According to the introduction, Beijing-Shanghai high-speed 1262 kilometers, the state Grid company in the line built 50 fast filling station, the average one-way 50 kilometers per one fast filling station. Each fast-filling station plans to build 4 120-kilowatt DC chargers and 8 charging piles, which can charge 8 electric vehicles at the same time and fill 30 minutes with (80%). 2 Chargers and 4 charge piles are built in advance to support all electric vehicles that meet China's standard.

Baic's owner, who participates in the "Beijing-Shanghai Line", said his electric car had been running in the city before, and that the electricity costs of commuting were less than that of buses. This highway to build charging station, for electric vehicle owners, is a good news, can also contribute to energy saving and emission reduction. Another owner said that the purchase of electric vehicles has been a friend decided to drive home for the new year.

After a rough calculation, the cost of electric vehicles is nearly half as much as that of petrol cars after the Beijing-Shanghai Expressway.

The state Grid said that the expressway charging service price, the implementation of local large industrial electricity prices, service charges to the location of the price management department issued price policy prevail. Large industrial electricity prices in general 0.65-0.8 yuan kwh, even after charging service charges, electric car charges will still be lower than the fuel vehicle oil costs, such as Jiangsu electricity price and charging service charges of 1.6 yuan kwh.

To the Beijing-Shanghai high-speed process as an example, in accordance with fuel vehicles hundred kilometers 10 liters of petrol, hundred kilometers fuel consumption costs 62.1 yuan, the entire fuel consumption of about 783.7 yuan. In accordance with the electric car hundred kilometers 20-kilowatt kwh, hundred kilometers of electricity consumption of 32 yuan (reference to Jiangsu standard 1.6 yuan kwh, including electricity), the total cost of electricity consumption is about 403.8 yuan.

The future "four vertical four horizontal" high speed equipped with filling station

The future, equipped with charging station is not only the Beijing-Shanghai high-speed.

According to the National Grid related officials, 2014, in Beijing-Shanghai, Beijing, Macao (Beijing-Xianning), Tsing Yin (Qingdao-Shijiazhuang), a total of 133 fast-filling station, fast-filled pile 532, the basic formation of "two vertical and one horizontal" expressway fast-filling network, the continuation of the mileage of 2900 kilometers. Since 2006, the state power grid has been built up to 618 rechargeable power stations, 24,000 charge piles.

By 2020, the planning and construction of "four longitudinal four horizontal" (Four longitudinal: Shenhai, Beijing-Shanghai, Beijing-Taiwan, Beijing Hong Kong and Macao, four horizontal: Green silver, Huo, Shanghai Rong, Shanghai Kun) for the support of the company to cover all the demonstration cities in the expressway fast-filling network, the continuation of the mileage of 19,000 kilometers.

However, there are still some challenges to be solved in high-speed and fast charging.

At present, the expressway fast-charging network uses the cash method charge charge. The state Grid said that the next step will be to build the company-level electric vehicle network platform to build electric vehicles cross-industry, the whole industry chain of the Internet business operation of the new model, promote a unified charging payment card.

In addition, because the popularity of electric vehicles is not high, charging for most people is relatively unfamiliar, and charging voltage up to hundreds of volts, current more than 100 amps. For safety reasons, the fast-charge service needs professionals for the time being. At present, with fewer vehicles, the operating cost is relatively large, in order to promote electric vehicles, it is not possible to convert all costs into charges. Therefore, the charging service operation pressure is big, but also needs to explore the innovation operation mode further.
