[Sohu automobile e-Park] the 2020 Forum of China electric vehicle 100 people's association with the theme of "grasping the situation, focusing on transformation and leading innovation" was grandly held in Diaoyutai State Hotel on January. At the electric vehicle infrastructure forum held on the afternoon of October 10, many experts in related fields gave keynote speeches on China's electric vehicle infrastructure industry from different perspectives. From the speeches of many industry experts, it is not difficult to see that the current development path of charging infrastructure in China is becoming increasingly clear, the existing problems are being effectively solved, and the number of participating enterprises is increasing, which is moving towards a good situation

[· 1. China's charging infrastructure has made sufficient preparations for the development of pure electric vehicles]

in 2019, the sales volume of new energy vehicles in China reached 1.18 million, and the ownership of new energy vehicles in the whole country reached 4.26 million, accounting for 60% of the total ownership in the world, still leading the world in terms of quantity. In terms of charging piles, by 2019, China has more than 35000 charging stations, an increase of more than 7000 over the previous year, with 516000 public charging piles and more than 700000 private charging piles, and the vehicle pile ratio has reached 3.44:1. On the whole, the construction speed of public charging piles in China decreased in 2019, but in terms of the total volume, the overall density is increased, and there is still a large increase compared with the past

[· 1.1. The business model of charging infrastructure is gradually clear]

at present, due to the insufficient number of charging users, the business model of charging facilities is not clear enough. The profit point of operators is relatively single, and most of them rely on charging service fees to support the operation of enterprises. At this forum, Zhang Fan, director of China electric vehicle charging infrastructure promotion alliance, made three summaries on the exploration of charging business model: the first is the diversified development of the profit model of charging operation. Charging service fee is the foundation of operating enterprises, and data service is a beneficial supplement. At the same time, a very important point is that the benefits of value-added services have also been highlighted. Our enterprises operate and cooperate with each other, and then provide platform access and subsidy services, provide services for the construction and operation and maintenance of private charging facilities, and also provide information service support for vehicle enterprises and travel service enterprises

the second is that operators are deeply involved in the charging segment. After several years of development, charging facilities operating enterprises have basically formed a relatively complete set of customized solutions for users. In the field of public transport, customized charging services are included. In the field of logistics, charging in the distribution center is the solution. In the field of taxi Hailing service, it is a relatively good high-quality station and comprehensive service. Now we also provide door-to-door charging for users in residential areas, Then it includes the situation of cooperating with the property community to jointly build charging piles and charging stations

third, the charging information service platform has effectively improved the operation efficiency, and the informatization level can promote the efficient operation of the industry. First, enter the platform big data analysis, and you can reasonably plan the layout of the charging station; Second, reduce the labor cost of operation and maintenance through the operation and maintenance of charging service platform; Third, provide online start and stop services, which can reduce manufacturing costs; Fourth, the effect of peak and valley electricity prices is relatively obvious. For example, power enterprises are also exploring the system construction of orderly charging of electric vehicles in residential areas, and have carried out pilot work in Beijing, Shanghai, Henan and other regions. It is believed that there may be a lot of market space in the future

[· 1.2. Car pile safety and compatibility. It reduces the risk of side effects of implants for a long time - at present, many patients have been adversely affected by permanent implants, and an effective solution mechanism has been established]

in 2019, China Association of automobile manufacturers, China charging Union and battery union jointly formulated the safety guidelines for electric vehicles on the basis of the 2018 version, Start with the electric vehicle industry chain and the whole life cycle, sort out the safety risks of electric vehicles. From 2016 to 2019, the national energy administration has been organizing the investigation of potential safety hazards, and investigated the potential safety hazards of charging facilities from the aspects of standard compliance, equipment quality, equipment communication information security, etc

in terms of vehicle pile compatibility, from 2016 to 2019, China charging Union and other relevant industries organized activities to test the interoperability of vehicle piles. The test results in 2016 showed that the charging success rate was less than 90%, and by 2019, the charging success rate reached "see copper materials passing through the base"; Melting pot rdquo; The latter is more than 98%, which reflects that China's charging capacity, including safety assurance capacity, has been greatly improved

[· 1.3. Policy support]

Zhang Fan, director of China electric vehicle charging infrastructure promotion alliance, mentioned in terms of policy support: in 2019, we did not see the introduction of independent national policies for charging facilities, but in the six national policies, we mentioned the infrastructure construction of charging facilities, including some subsidies. For example, the notice on financial subsidies for the promotion and application of new energy vehicles mentioned that local subsidies should be transferred to support the short board construction and supporting operation services of charging infrastructure. Under the national environment of streamlining administration and delegating power, it is also clear that the charging range of local government pricing and operation services includes the charging and replacement service charge of electric vehicles. In subsequent documents, such as the guiding opinions on promoting the implementation of energy storage technology and industrial development, including the plans to promote the upgrading of key consumer goods and smooth resource recycling, including our outline for the construction of a transportation power, charging facilities are mentioned, On the whole, in terms of national top-level policies and relevant coordination policies of various ministries and commissions, they still strongly support charging facilities, which is relatively good news

at the same time, in terms of policies, director Zhang Fan also suggested that "subsidies and incentives can be given to the construction and operation of charging infrastructure, the development of charging facilities can be encouraged, and the policy of local subsidies to subsidize charging can be implemented at the same time." In addition, Zhang Fan also mentioned two aspects: one is to encourage and guide the use of clean energy. What really makes new energy vehicles reflect is clean energy, which is real new energy; Second, we hope to carry out the interactive demonstration of electric vehicles and electricity, so as to prepare for the promotion of our comprehensive utilization of V2G related technologies in the future

[· 1.4. Future preparation and exploration]

academician Huang Qili of the Chinese Academy of Engineering said that there have been several stages between the car and the car. Now it is the first stage of v0g, which is disorderly charging. At present, the owners of electric vehicles basically do not consider when it is most appropriate to charge. Next, we will start v1g, that is, orderly charging. Now we have begun to do so. The next step is V2G, which is to charge and store electricity. In the future, when the vehicle is integrated, it is not only an integral part of the whole society. When transportation, electric vehicles and electricity become an integral part of it, we can achieve the correct two-way charge and discharge at a scientific and controllable time and in a flexible and convenient place, which not only realizes the development of electric vehicles, but also supports the development of renewable energy, Of course, it also meets the use needs of electric vehicle users

v2g is coming, and the integrated vehicle is expected to further play the two-way role of both charging and storage of electric vehicles. "Vehicle integration can realize the correct two-way charging and discharging in a flexible and convenient place at a scientific and controllable time, which not only realizes the development of electric vehicles, but also supports the development of renewable energy. Of course, it also meets the use needs of electric vehicle users. It can truly charge electric vehicles with green electricity through green electricity trading, auxiliary services and demand response." Academician Huang Qili said

with regard to wireless charging, Xiong Jingquan, general manager of ZTE New Energy Automobile Co., Ltd., believes that "from 2017 to 2020 is the exploration period of the wireless charging market, 2020 to 2023 is the market penetration period, and 2023 to 2025 is a market promotion period. We predict that after 2025, wireless charging will be a period of rapid development of electric vehicles." At the same time, he also described a scenario of wireless charging to us: after arriving at the charging station, you can start automatic parking, and the car will find a parking space. At a close distance, our wireless system will automatically align with the ground end of the parking space. At this time, there is a communication "handshake" between the waiting vehicle end and the ground end, and automatic charging is started on the premise that you need to charge and can charge, The whole process is very cool. It doesn't need to pull out the charging gun

[· 2. The road of vigorously developing new energy vehicles should not be shaken]

academician Huang Qili of the Chinese Academy of Engineering discussed the necessity of developing new energy vehicles from the perspective of China's energy transformation. Academician Huang Qili summarized the main ways and means of China's energy transformation as the cleaning of primary energy, the electrification of secondary energy, the intellectualization of electricity development, and the socialization of energy conservation. Although the location of electric vehicles is small, it connects four aspects. It can not only improve the cleaning of primary energy, but also improve the electrification of secondary energy, but also improve and strengthen the intelligence and energy conservation of electricity. Therefore, the development of electric vehicles is in line with the view of the system, and will play a role of 1+1 greater than 2 in large systems

academician Huang Qili dispelled concerns about whether the power supply was insufficient. Academician Huang Qili believes that our country's electricity is the world's largest, technically the world's highest and safest in terms of electricity and power generation. Therefore, this electricity can support the development of electric vehicles. If 100million pure electric vehicles are developed, the annual charging capacity is calculated according to 200billion kwh, accounting for only 2.9% of the total social consumption in 2018 and 1.7% of the electricity consumption in 2035. Therefore, from a macro perspective, there is no problem with electricity, and it can be developed without arms, because renewable clean electricity is enough

academician Huang Qili put forward three suggestions for the future development of new energy vehicles and charging infrastructure:

1 We will unswervingly adhere to the development route of new energy vehicles and promote the integrated development of new energy vehicles and energy transformation. It is suggested that in recent years, we should focus on pure trams and realize large-scale charging as soon as possible. Green electricity should be charged for new energy charging, and green electricity from renewable energy should be charged. Hydrogen fuel vehicle is one of the future directions, but it is still in the cultivation period. We should strengthen the scientific and technological research of hydrogen fuel cell

2. Strengthen the overall layout of charging and changing electricity, and make scientific interconnection and orderly interconnection form a benign ecosystem. Now when electric cars need charging
