Core Summary

Since last June, according to the State Department's Division of Labor, the National Energy Bureau has begun to develop "electric vehicle charging Infrastructure planning" (hereinafter referred to as the "planning"), the end of last year has completed the first draft, the future and "planning" at the same time also "charging infrastructure construction guidance."

"Infrastructure has become a bottleneck in the promotion of new energy vehicles, we have to gather wisdom in all aspects, to make it clear, to form a consensus, to provide Governments and enterprises with some proposals to formulate relevant policies, regulations and action plans." ”

On March 2, Euyangminggao, executive vice president of the Chinese electric vehicle, said at a closed-door seminar on electric vehicle infrastructure that infrastructure was the first subject of the 2015 Hundred People study.

Inadequate infrastructure is becoming the main bottleneck restricting the development of electric vehicles. Authoritative data show that in 2014, the number of new energy passenger cars in China has been close to 90,000, but the number of charged piles has been built is only 30,000. In Beijing, for example, the proportion of electric cars and recharging facilities in Beijing in 2010 and 2011 was 1:1, then 1:2, and 2014 to 1:3, which means that an average of 3 vehicles had a charging facility.

In fact, since last June, according to the State Department's Division of Labor, the National Energy Bureau has begun to develop "electric vehicle charging Infrastructure planning" (hereinafter referred to as the "planning"), the end of last year has completed the first draft, the future and "planning" at the same time also "charging infrastructure construction guidance."

It is understood that the "planning" to achieve by 2020 the development of 5 million new energy vehicles to advance the target, the overall assumption is that the number of power stations in the future to reach 12,000, charging pile reached 4.5 million.

Not only standards but also certification

In the actual use of electric vehicles in the process, the charging standard is not uniform problem is very obvious. BEIJING-Shanghai Expressway charging station after the full opening, there are enterprises to send a working group to do electric car run test, the result is that the car can recharge the charging station, the car could not charge, to the next charging station, the car can recharge, the car is not charged.

Although the state-level charging interface has been GB, but the user still feel is not unified, not universal, in the end where the gap? In this regard, Liu Yongdong, deputy director of the Standardization Center of China Electric Enterprise Federation, who is responsible for standard-setting, March 6 in an interview with the economic reporter in 21st century, said, "On the one hand, the standard also needs to be improved, at the same time the facilities and car to do the interface is really in line with Local standards have been developed in the light of their own ideas, and the transitional phase is now being formed. ”

Liu Yongdong stressed that the current revision of the interface GB is to solve this problem, at the same time to start the establishment of interface standards conformance detection standards to solve whether the real national standards for testing. The state has made it clear that charging facilities must conform to national and industry standards and cannot have local standards to solve the problem of standard contradictions.

"Hundred people" Day, from the enterprise level, many people in the industry called for, hope that some standards can be issued as soon as possible, and establish a charging pile certification system, otherwise blind investment will produce huge waste.

"Large-scale promotion of new energy vehicles, whether it is electricity or electricity, there is no standard of charging facilities that can provide a wide range of voltage and communication protocols, and large-scale infrastructure is a waste, in which individual investors can make a profit from state subsidies and other forms of invisible income, and from the perspective of the return to the country, Actually a bit blindly push, waste social resources. "There are insiders who are outspoken.

The work of certification is very important. "A one-time test is a more urgent matter, that is, the car and charge pile certification, the car company said his products in line with GB, charging facilities also said that their own charge of the pile in line with GB, but there is no unified evaluation scale, so that some cars can be charged in this pile, but can not charge in another pile. Liu Yongdong said that now the automotive laboratories are ready to carry out a one-time test, but according to what scale, what procedures to judge the need for a unified standard, is currently doing this work.

"There is no certification standards, the standard will become a mere formality, at present only some of the owners in the tender request for the type of experimental reports, but often due to the current situation in China, many enterprises submitted to the equipment, and the final operation of a big difference." Therefore, in addition to the type of experiment, plant inspection and inspection system also need to be established, or all said to conform to GB, but the actual situation can not be used for a long time. In addition, these requirements are not only required for charging equipment enterprises, but also for automobiles. Nupheng, deputy general manager of Electric Power Company, which specializes in charging infrastructure construction, said in an interview with the 21st century Economic report.

Unified standard set for new energy access conditions?

China Electric Enterprise Federation Standardization Center and China Automotive Technology Research Center, Electric Vehicle Standardization Technical Committee cooperation, Division of responsibility for charging facilities standards. In the past five years, the standard system of electric vehicle charging facilities has been basically built, and there are about 58 standards, including charging and power-changing standards. So far, 27 standards have been issued, and the required standards for EV charging facilities are largely complete, but there are a number of standards to be updated and perfected.

"The focus of our work in the first half of this year, the core of the problem is this testing standards, testing standard system construction is the most important." "Liu Yongdong said.

This year also promoted the revision of the national standard of electric vehicle charging. On the revision of the national standard, the focus includes: first to the previous version does not have a clear refinement of the place, we have ambiguous place to further refinement and clarity. Second, there may be additional flaws that are found in practice, such as security issues.

"At present, the state has put the interface standards into the new Energy vehicle Purchase Tax Relief Directory access conditions, the next step will be included in the new energy vehicle access conditions, to solve the problem of the implementation of the standard is not strong." Liu Yongdong said that this is the basic work, if the new energy vehicles into the access conditions, then from the source manufacturers will be concerned about interface standards.

Not only that, the next country will also be the standard of charging facilities as a model city assessment criteria, that is, whether the charging infrastructure in accordance with national standards to do, such as the charging interface standards, as the model city assessment conditions.

In fact, the corporate level on the unification of the standards of charging and attention is also very high. Before the "hundred People's Meeting", February 5, the third meeting of China-Germany Electric vehicle Standardization Working group was held in Beijing, the two sides focused on the standards of interface standard, safety of vehicle batteries, inductive charging, fire safety, electromagnetic compatibility and so on.

Notably, the mainstream international auto companies have been prepared to cope with the charging problem. "What we are doing now is a comprehensive charging management system, one of the most critical technology is wireless charging, we have with Japan, Europe first-class car factory in this area has a wide range of cooperation, developed a wireless charging technology." In the future this may be a revolutionary product that really cancels out everyone's anxiety about mileage. "Delphi Asia Pacific Engineering director Li Yu in an interview with the 21st century Economic report," he said.

At present, the traditional charging method has three global standards: the first appearance of the United States SAE Standard, Japan, South Korea also adopted SAE standards, followed by European standards, and then China's standards, between the European and American standards. This creates three completely incompatible standards. "The reason why wireless charging is more attractive is that we hope to solve the problem of unified standards, but the current technology standard of wireless charging is completely in the starting stage." Li Yu stressed.

The bottleneck of the large-scale private charging pile

At present, there are several reasons for the slow development of electric vehicle charging facilities in China: first, the development path of electric vehicle itself is not particularly clear and clear; second, the charging technology is changing rapidly, with fast charging, slow charging, and wireless charging and other new forms, charging facilities should be built, what kind of charging facilities Especially to the increasingly market-oriented private new energy passenger car, what kind of means, according to what mode to develop. Third, the operation of charging facilities is not particularly good or can be accepted by the market operation mode. The immaturity of these three areas has brought great difficulties to the construction of electric vehicles ' infrastructure.

"Hundred people will" the same day, Euyangminggao repeatedly stressed that electric vehicles to achieve large-scale, commercial, the core problem is to solve the problem of home car slow charge. "With the public mainly built more power station can not solve the problem of private car charging, public cars and how to push the number is limited, and how to push the shape of an industry, not a strategic emerging industries."

At present, the developed country's electric vehicle market is mainly the development of private passenger cars, the United States private passenger car charging 14% in the office space, 66% at home, its charging infrastructure construction is related to the family. The Japanese approach is clear, with a slow-charging, slow-charging and fast-charging ratio of 4:1. Europe, similar to Japan, has more than 10,000 slow-filling piles, only more than 100 fast filling stations.

With the rapid growth of private electric vehicles in China, the problem of charging piles emerges, while private electric vehicles have different requirements for charging infrastructure. Zhang Jinhua, executive vice chairman and secretary general of China Automotive Engineering Society, suggested that the construction of China's rechargeable infrastructure should be based on a fixed exchange-charging facility and a public quick-charge supplement, so the principle should be determined.

Charging infrastructure is not a simple technical problem, but a systemic problem, involving policy, land, planning and the distribution of rights and interests of various stakeholders. For example, charging facilities into the community involves individual and individual interests, the Government is not good interference.

With regard to the business model of charging facilities, a lot of private capital has been entered and a lot of capital is being tempted, but now infrastructure operations are basically losing money. At present, unified charging standard first, at the same time to solve the core issues there are business models.

"Charging facilities and electric vehicles are actually a rolling development, mutual promotion process, not necessarily infrastructure construction good electric vehicles can develop." Liu Yongdong finally said that the problem of charging facilities from the whole industry chain to consider to be profitable, alone, whether the car manufacturers or power companies can not be completed independently.
