New energy automotive industry has risen to the height of China's national strategy, relying on the development of new energy vehicles to achieve long-term car power dream has become a consensus. In the industry with Sensor the concerted efforts of the community in recent years, China's rapid development of new energy automotive industry, has made remarkable achievements. Compared with the rapid development of new energy vehicle market, charging infrastructure construction has not been the corresponding development, charging station / pile construction costs are high, low income, the number is not enough, the layout is unreasonable, interconnection is not up to this series of questions if Not as soon as possible to be properly resolved, the future development of China's new energy vehicles can be described as worrying.

  From the scale of production and sales, China's new energy vehicles in the global market share of more than 50%; from the enterprise competition, BYD, Yutong have become the world's new energy passenger cars, commercial vehicle sales champion; from the product technology point of view , Vehicle driving range, battery energy density, platform / lightweight and other levels have been rapid increase. In the new energy automotive industry to see the results achieved at the same time, we should see the development of the shortcomings - from the perspective of the whole industry chain, China's new energy automotive industry in the front, the end of the great progress, But this does not cover the actual situation Suction Control Valve of its back-end lag. In the field of charging infrastructure, at present, China has built a total of about 180,000 public charging piles, plus the number of private charging pile, the total vehicle pile ratio of about 4: 1, which is far from the new energy vehicles can not meet the normal charging needs. In the industry front and mid-range rapid situation, the back-end lag bottleneck is becoming increasingly prominent.

  China's new energy vehicles, the rapid expansion of the scale of production and construction and infrastructure construction lag behind the contradiction as ice is not a day cold, it is a long-standing chronic illness. Although the number of charging piles is increasing rapidly, the pile ratio is also increasing to the current 4: 1 year, but it can not be ignored is that the growth rate of new energy vehicles is still significantly higher than the number of charge pile growth scale, which means that the pile The gap between the two is still expanding. In the case of 2015 and 2016 statistics, for example, the number of public charging piles has increased by 100,000, but the number of new energy vehicles has increased by more than 170,000 vehicles, still not 1: 1 synchronous growth, but also An increase of 70,000 gap. In the face of the chronic problems of charging infrastructure construction, in October 2015 the state has issued a program on the development of charging infrastructure - 'on accelerating the construction of electric vehicle charging Temperature Sensor infrastructure guidance' (State Council issued 〔2015〕 73 ), Clear the overall requirements of the construction of charging facilities, from the increase in construction efforts to speed up the cultivation of the market, strengthen support and support, do the organization and implementation of four aspects of the 18 policy requirements. The National Energy Board has issued a guidance document on the construction of the charging infrastructure 'Electric Vehicle Charging Infrastructure Development Guide (2015-2020)', put forward the 2015-2020 classification, sub-regional charging facilities planning and construction goals. Among them, it is proposed that by 2020, more than 12,000 new rechargeable power stations will be added, and more than 4.8 million will be distributed to meet the charging demand of 5 million new energy vehicles.

  Public charging station construction costs mainly by the equipment, land, electricity capacity of three blocks to the second-tier cities a small charging station (10-15 sets of chargers), for example, equipment costs about three million, power capacity also Need 100-200 million range, coupled with the cost of land and the latter part of the operating costs, tens of millions of investment can not beat. Even in accordance with the Wuhan subsidy policy, can only get more than 100 million of the amount of subsidies, investors still need to invest more than 800 million. The current sales of new energy passenger cars have been close to the total amount of 70%, and this figure is still rising. In this case, the private car has become the main demand for new energy vehicle sales, 2017 in the first half of the insurance data show that individuals to purchase new energy vehicles accounted for 88.5% of users. Obviously, by 2020, 5 million new energy vehicles, there will be the vast majority of private users. For such users, really can improve their charging experience, not a public charging pile, but built their own private charging pile. The current data show that the number of private charging pile only less than 30,000, crude point that is less than the public charge pile is also insufficient! Especially the transformation of the old district, it is even more difficult, especially Speed Sensor the power capacity, who can not tell why, it has been shelved pending, and just, the old owners of the old district is the future of new energy The main group of car demand.
