The rapid development of China's economy has directly driven the consumption level of the broad masses of the people. After everyone solved the basic problem of food and clothing, the quality of life has gradually improved, such as the comfort experience of living and the emphasis on the sense of travel experience. Therefore, private cars are becoming more and more popular, which is undoubtedly a good development and further promotes the development of social economy, However, the following environmental problems are becoming more and more serious. The lack of energy may even face exhaustion. In such an environment, the government has adopted vehicle restrictions to improve the environmental pollution problem. Most of the automobile enterprises also take the opportunity to develop new energy vehicles based on electricity to occupy the car market. It has been proved that the listing of new energy vehicles has also been vigorously supported and promoted by the national government, It has made another great contribution to the economic development of the country, but the following new problem is also a headache, that is, the difficulty of charging new energy vehicles.
Throughout the world, green development has become the theme of development in countries around the world. Our country has also begun to promote the use of new energy vehicles and encourage the support of new energy industries, which is an important manifestation of China's commitment to green development. So the most important thing for new energy vehicles is to use on-board power to ensure the charging capacity of electric vehicles, Therefore, the layout and planning of the charging station become the key.
At present, the layout of charging piles is developing rapidly in the urban areas and high-speed service areas of major cities in China. However, the development of electric vehicles and the facilities of charging piles are still uncoordinated. In most regions of the country, it is difficult to charge and the queue time is long. The construction of charging piles is unreasonable and the number is not enough to meet the growth of electric vehicle ownership. The national government is also very concerned about this, and is also introducing some policies to try to solve the problems.
In 2011, the State Grid put forward the concept of "power exchange as the main, plug-in as the auxiliary, centralized charging and unified distribution", which is based on the consideration of the situation at that time.
Now, with the progress of battery research and development technology, fast charging is possible, and the level of domestic manufacturers is also constantly improving. In 2014, the State Grid has changed into the idea of "leading fast charging, giving consideration to slow charging, guiding power change, and economic and practical", and introduced social funds and forces to participate in the construction of charging facilities.
Up to now Electric vehicle charging pile It has reached 26000, and the draft of the Electric Vehicle Charging Infrastructure Construction Plan formulated by the Energy Administration has been completed. It is optimistic that by 2020, the cumulative production and sales of new energy vehicles will exceed 5 million. According to the calculation that one car corresponds to one slow charge and 0.2 fast charge, it is estimated that by 2020, the market demand for 5 million slow charges and 1 million fast charges will be generated. With the accelerated construction of charging piles, the future investment in charging equipment will exceed 85 billion yuan.
