"Growing pains" of charging piles: standardization is a long-term task

The construction degree of charge pile and charging power station directly affects the large-scale commercialization of electric vehicles, but it is not enough to increase the layout of charging facilities, but also need to build efficient and perfect charging service network.

In fact, at present, the strength of the manufacturers all want their own research standards can represent the industry standards, each of them think they have mastered the more core technology, and will not be easy to open to the outside, all hope that the company will be upstream of the production and sales of electric vehicles to downstream charging technology and pile construction into one, Build a whole industry chain of companies.

723 charging stations, 28,000 charge piles. This is the Ministry of information about the current domestic charging stations and charging pile the latest statistics. These two numbers are still being updated quickly.

2014, the international famous electric car brand Tesla entered the Chinese market, cool appearance and the power system to carry to the Chinese consumer and many automobile enterprises brought the visual and ideological impact.

Subsequently, the new energy companies in the precipitation of a considerable number of experimental products, began springing up, many manufacturers to launch their own electric car products to compete for this market segment.

The construction degree of charge pile and charging power station directly affects the large-scale commercialization of electric vehicles, but it is not enough to increase the layout of charging facilities, but also need to build efficient and perfect charging service network.

January 27, in a regular press conference, the Ministry of Industry and Information technology operation Monitoring and Coordination Bureau director Zheng said: "2014 new energy vehicles have been rapid development, a total of 83,900 new energy vehicles a year." ”

The blue-sea effect of industry naturally aroused strong interest of all parties. But the reporter learned that the rapid growth of data behind the charging pile industry is carrying out "barbaric growth." There are contradictions between the various stakeholders in the industrial chain and no compromise, and there is a lack of uniform rules for their implementation.

Electric pile industry: rapid growth in questioning

The development of electric vehicle will be promoted by the improvement of the charging pile and charging station. Like the electric car industry, the construction of rechargeable piles in the country is also constantly creating new records.

The Ministry of Public Information released January 27 The latest data show that at present the domestic has built 723 charging stations, 28,000 charge piles. Among them, the State Grid company built 618 power station, charging pile 24,000. According to the Thirteen-Five plan, it is expected that by 2020, the centralized charging station will grow to 12,000 seats, and the number of decentralized charging piles will increase by 100 times times to 4.5 million.

It is based on the development concept of "charging facilities construction network, scale", in mid-January, the first expressway Intercity fast network---------Beijing-Shanghai Expressway Fast-filling network, has become a milestone event in the development process of charging pile industry.

According to the data provided by the State Grid, 50 fast filling stations are built along the high-speed line, averaging one fast filling station per 50 km. Each fast-filling station plans to build 4 120-kilowatt DC Chargers, 8 rechargeable piles, can be charged for 8 electric vehicles at the same time, 30 minutes full (80%), the advance construction of 2 chargers, 4 charge piles, to support all Chinese-standard EV charging.

However, the reporter confirmed from some Tesla's owner, Beijing-Shanghai high-speed fast-charge network through, some domestic use of national electrical technology, domestic electric vehicle friends, spontaneously organized a experience of the Beijing-Shanghai charging network activities, some sections of high-speed charging stations can not be charged for electric vehicles, and ended in failure. Thus causing the owner to question the "through" said.

Some owners pointed out that the 1000-kilometer-covered charge line network is the state-owned electricity charging technology, that is, the domestic market to sell better foreign models (the basic is Tesla) can not be in this fast-charging network to get due resources, because the two sides of the charging standard does not match.

The State grid in hindsight, the explanation is that it can recharge, but need to advance to the National Grid customer service to call to open the charging pile, users can not operate on their own.

Liu Yongdong, deputy director of the China-ITU Standardization Center, said in an interview with the 21st century economic Reporter: "The development of charging facilities and electric vehicles complement each other, only by allowing the network and scale of charging facilities to promote the development of electric vehicles, and the construction of high-speed charging network is an important link to the network." ”

According to the plan, by 2020, the national power grid planning and construction with "four longitudinal four horizontal" (Four longitudinal: Shenhai, Beijing-Shanghai, Beijing-Taiwan, Beijing Hong Kong and Macao, four horizontal: Green silver, Huo, Shanghai Rong, Shanghai Kun) for the support of the company to cover all the demonstration cities in the expressway fast-filling network, the continuation of the mileage of 19,000 kilometers.

Road to standardization: chaos in the early stages of development

According to the recent promulgation of the "government agencies and public institutions to buy new energy vehicles Implementation Plan" stipulates that the charging interface and the number of new energy vehicles is not less than 1:1. By this standard, although the number of charging piles has been increasing rapidly, the existing charging equipment can not meet the current needs of electric vehicles.

Not only the national grid, more private capital into the industry, multiple capital intervention after the distribution of benefits has become the most important concern.

"In such a period of development, whether it is the manufacturer of electric pile supporting industry, as well as EV and rechargeable battery manufacturers, are doing their own business in the field of good, hoping to gain more market or resources." "People familiar with the electric car industry reported to the 21st century economic reporter.

In fact, at present, the strength of the manufacturers all want their own research standards can represent the industry standards, each of them think they have mastered the more core technology, and will not be easy to open to the outside, all hope that the company will be upstream of the production and sales of electric vehicles to downstream charging technology and pile construction into one, Build a whole industry chain of companies.

"Can not say that this is not good, but this led to the situation is-the outside world seems to blossom in the field of electric vehicles, in fact, are playing with their own, there is no one can be implemented uniform play." When consumers actually own an electric car and use it, they find that it is an extravagant hope to be able to rush their electric vehicles in time or quickly. ”

"The purchase of an electric car is not complicated and subsidized, but the ensuing problems make it difficult for users to evaluate the industry satisfactorily," the person told reporters. ”

At present, the scope of electric vehicle activities is more or less within the city, but in the city to find a charging pile is not a very easy thing, sometimes found the charge pile may also appear leakage damage.

And the country before the introduction of the subsidy policy for the establishment of charging piles, but after the completion of the operation and maintenance, but has become a lot of enterprises do not want to take the link, the state's subsidies can not be the most effective use.

"Electric vehicle charging facility layout is a process from government to enterprise and individual, the parties open cooperation, need to break through the barriers between all walks of life, to achieve cross-sectoral cooperation." "It would be unrealistic for these parties to be able to sit down and work together to create a workable universal system or standard, at least in the short term, which requires a strong intervention by the country's relevant regulatory authorities," the industry said. ”

In Liu Yongdong's view, the charging interface has now achieved the standard unification at the national level. Its landmark event is the 2011 years of China's electric vehicle charging interface and communication protocol standards approved the release, namely, "Electric vehicle conduction charging connection device 1th General requirements", "electric vehicle conduction charging connection device 2nd part of the AC charging interface", "Electric vehicle conduction charging connection device 3rd part DC charging interface, the communication protocol between non-vehicle conducting charger and battery management system of electric vehicle.

However, there are many problems in the market. "The standardization of charging facilities is a long-term task," Liu Yongdong said in a previous media interview. With the development of electric vehicle scale, the standardization of charging facilities needs to be revised and perfected constantly. ”

The challenge of moving forward

At present, the declining oil prices and the market on the new energy car bad customer experience, or let some traditional car owners have a psychological tendency to stay away from electric vehicles. Despite the above policy and technical challenges, the charge pile will also face the competition of new things.

At the end of December 2014, an American start-up company said it would launch a car-specific "mobile charging treasure", breaking the limits of fixed-charge piles, is expected to solve the electric mode of travel worries.

"Mobile charging treasure" with the wheel easy to move, electric vehicle owners parked the car, mobile charger can be anywhere to charge for it, the future of a device storage can even meet the charging needs of 5-8 electric vehicles.

21st century economic reporter from a number of mobile power manufacturers understand that there are already domestic enterprises in the electric vehicle market is developing similar mobile power products.

"A lot of competing interests will not smooth the way for the development of electric cars and piles, but we want to rely on the internet for more consumers to have a better experience with electric cars." "A platform designed to help maximize the use of rechargeable piles, the founder and CEO of the pile, said in an interview with the 21st century economic reporter," When the parties are able to develop under a proper rule, the perfect user experience we create can be seamlessly connected to technology from the client. ”

The platform is defined as a third-party integrated service for electric vehicles in China, which aims to solve the problem of charging in the industrial chain.

According to the first introduction, at present, "electric pile" not only integrated the national charge pile database, login can also find nearby charge pile, repair point and navigation to the user can make an appointment to charge piles, pay can also be evaluated, can even share their own home charge pile to other car friends.

"It is hoped that through this platform the existing charging facilities will be connected online to build up the largest charging service network in China." "The more to the reporter revealed that the electric pile will be set up in Shanghai branch," the establishment of this ecological is also hoping to further optimize the electric pile to the user experience.
