In order to support the development of new energy, the country is really shattered. In addition to giving various car companies and car owners various preferential subsidy policies, now even the hardware has begun to be personally owned by the State Grid. On the 11th of this month, Shu Yinbiao, chairman of the State Grid Corporation of China, said that in order to accelerate the construction of the highway charging network and build China's charging and replacing standard system, the State Grid plans to build 10,000 charging stations and 120,000 charging stations by 2020. Piles, in Beijing, Shanghai, Hangzhou and other cities to form a public fast charge network with a radius of no more than 1 km. During the “13th Five-Year Plan†period, it plans to cover 36,000 kilometers of expressways, which will facilitate the “world†of electric vehicles.
The imperfection of infrastructure such as domestic charging piles has always been one of the important reasons that restrict the development and popularization of new energy sources.
Domestic charging pile enterprises are even faster than new energy vehicle enterprises. At present, there are more than 300 known companies. At the same time of competition, the quality of products, industry standards, business control, charging between enterprises The pile standards are different, it is difficult to be compatible, and the charging network interconnection process is slow.
Low utilization rate is also a big problem. Idle charging piles cannot be effectively utilized. According to investigations, the effective utilization rate of charging piles is only 5%, and the idle rate is as high as 70%. Personal car owners do not understand the quality of the external charging network, and it is difficult to trust, preferring to choose to charge at home; in small cities with small population density, not prosperous, or suburbs, the demand for charging piles is smaller.
The application process for personal charging piles is also complicated and complicated. To buy a car, it is necessary to build piles first. Many people have instead switched to non-new energy vehicles.
The National Grid's 120,000 charging piles are integrated in the future coverage and unified charging piles. In addition, the State Grid has set up a State Grid Electric Vehicle Company to implement the special management of the electric vehicle charging and replacing business. One of the biggest highlights is the establishment of a “vehicle networking†platform that integrates functions of monitoring, searching, and settlement of charging and replacing facilities, which can solve the problem of difficult to find and difficult to charge for electric vehicles. At present, more than 80,000 charging piles have been connected, of which about half are self-built by the State Grid and half are from other companies.
Guangdong, as a developed province, has begun to deploy the construction of charging facilities in Guangdong during the “13th Five-Year Plan†period last month. Its total investment is estimated to be about 54 billion yuan. It is estimated that the output value of power batteries will be about 42 billion yuan, and the output value of electric vehicles will be about 220 billion yuan.
The province's goal is to build 1,490 centralized charging stations in the province by 2020, including: 590 bus charging stations, 170 taxi charging stations, 300 dedicated charging stations for logistics and sanitation, and public charging stations 330. Block and use the expressway service area to build 100 intercity fast charge stations; build about 350,000 distributed charging piles.
The large-scale construction of charging piles not only brings convenience to ordinary electric vehicle users, but also welcomes new energy buses to develop opportunities.
Building a charging pile network is only a small step at present, and there will be more problems in the future: the charging compatibility problem of the vehicle enterprises, the grid access, the electrical equipment upgrade, the power supply, the charging time allocation, etc. are no more than the charging pile itself. The construction and transformation are difficult. These require the relevant industries to design and produce under the new national standard, in order to make resource utilization more efficient and achieve real convenience.
