According to the statistics of the National Electric Vehicle Charging Infrastructure Promotion Alliance, as of the end of June this year, there were 81,800 public charging piles in China; among them, 13,500 DC piles; 16500 AC and DC integrated piles; and 51,800 AC piles; The year-end growth was 65%. There are a total of 55,400 private charging piles, an increase of about 12% from the end of 2015, and the pile-to-pile ratio is about 4:1. Faced with a 4:1 ratio, Liu Yongdong, deputy director of the China Electricity Council's Standardization Management Center, seems to be dissatisfied. He said at the first China Charging Pile Innovation Summit on July 27 that last November 17, the National Development and Reform Commission, The National Energy Administration, the Ministry of Industry and Information Technology, and the Ministry of Housing and Urban-Rural Development jointly issued the "Guidelines for the Development of Electric Vehicle Charging Infrastructure (2015-2020)", proposing to build 4.8 million piles and 12,000 stations by 2020. The proportion of trucks will reach 1:1. . It can be seen that the development space from 4:1 to 1:1 is very huge, and the construction of charging infrastructure will usher in rapid growth in the next five years. The daily economic journalist came to the State Grid public charging pile near the tea city of Maliandao, Xicheng District, Beijing. Ms. Zhao, who is charging the car, told reporters that if she does not have a charging pile, then she must buy a pure electric car. Doing "homework" can avoid a lot of unnecessary troubles. Ms. Zhao further said: "I am now a customer of many charging pile operators. The car has long been charging the national grid and Putian New Energy. There are 4 APPs on the mobile phone for charging the pile. Only in this way, my heart Only be practical." At the same time, the owner of the electric vehicle has shown to reporters that when the public charging pile is used to charge the car, when the power reaches more than 90%, the charging pile will not continue to be charged. The official explanation of Tengshi Auto is that this problem is caused by insufficient voltage of the public charging pile. The output voltage of the charging station of Tengshi Electric Vehicle can cover the range of 220Vdc~550Vdc, and the charging pile screen shows that the charging voltage is too high. When the voltage of the vehicle's power battery is consistent with the maximum output voltage of the public charging pile, it is no longer possible to continue charging the vehicle's power battery. For these problems, Liu Yongdong, deputy director of the Standardization Management Center of the China Electricity Council, believes that the charging pile standards are not uniform and cannot be interconnected. China's charging pile construction is at the peak of industrial development. Through several years of hard work, standard work has achieved certain results. The standard system for charging facilities construction has been basically established, and key standards have been introduced one after another, which can basically meet the needs of the development of charging facilities. The standard system covers the inspection specifications and becomes the basic condition for each operator to purchase equipment, which is beneficial to standardize the quality of charging facilities. According to Liu Yongdong, the current charging interface and communication protocol standard architecture has been completed. The charging interface and communication protocol standards formulated according to China's national conditions were released at the end of 2011 and implemented in March 2012. It mainly includes three charging interface series standards and DC charging communication protocol standards. The 2015 version of the series upgrade standard has been released. In terms of key equipment standards for charging facilities, electric vehicle AC charging piles, DC chargers, and vehicle-mounted conductive chargers were approved for release in 2010, and the series of electric vehicle charging equipment inspection and test specifications was also approved for release in 2013. It also initiated the preparation of nine charging station construction standards including the design, construction, construction and acceptance of charging stations including the General Requirements for Electric Vehicle Charging Stations. In terms of power exchange standards and operation and maintenance standards for charging facilities, a series of standards including operational metering, operation monitoring, operation platform communication, and logo identification have been developed. Liu Yongdong said that these standards are playing an active role. At present, the interface standards are gradually unified, and the charging equipment standard has become the basis for manufacturers to manufacture products and the bid for enterprise procurement. Fortunately, in the new energy vehicle purchase tax reduction and exemption method, whether it meets China's charging interface standards and communication protocols is also included in one of the conditions. Liu Yongdong said that the next step in the charging standard is the improvement of the information interconnection standard. The first is to establish a national unified coding standard to solve the problem of pile coding, and to build a unified information exchange standard system, namely, "Electric Vehicle Charging and Replacement Service Information Exchange Standard", which can meet the government's effective statistics and meet operators and operators. Exchange of facilities and services, exchange of charging process, to meet the owner's charging query. It consists of four parts: general rules, public information exchange specifications, business information exchange specifications, data transmission and security. It is divided into four levels, that is, the information access layer, the information for the car can also be the information of the charging card; the infrastructure layer is Information on charging piles; operational service layer and data sharing layer. After the implementation of the standard, the owner solves the related problem by means of the current mobile phone roaming. Solve the standard charging process and build a cross-platform standard charging process for the two operators. To solve the identification problem, each owner can know who the operator is after charging to another operator. The user charging fee is still paid to the original operator, and the background settlement is solved by the two operators themselves. According to Liu Yongdong, the standard has previously completed public consultation on the Internet. Currently, standard pilots have been launched in Beijing, Shanghai and Shenzhen. Major domestic operators are involved in standard verification. It is expected that the information exchange standard will be officially announced to the public in September. The operator follows this set of rules. Secondly, a unified national information publishing platform was established. According to Liu Yongdong, the main task of the national charging service information platform is to count and provide basic public services. It is necessary to establish an information reporting system between the operation management systems of local governments and operators and state-level information platforms to realize information interconnection and intercommunication of charging services. Through the reporting system, the national information platform can complete the statistical analysis of the existing charging infrastructure data, scientifically and accurately count the data of the charging infrastructure in different periods and different places, and publish it to the public in a timely manner. Through the reporting system, the charging infrastructure data can be unified, and the authoritative and comprehensive charging facility basic information can be provided to the society to realize the maximum layer sharing of charging facility resources.
There are plenty of benefits for using usb type c cable For starters, the port is reversible! But that is only the tip of the cable. And like ice bergs, there is much more than meets the eye in type c cables. They allow for faster transfers, charging, 4K monitor output and more.
Needless to say we will have to start populating our living spaces with usb 3.1 type c and accessories.It measures in at 1.8 meters of length and can handle USB 2.0 charging, as well as up to 60W of fast charging power. Not bad at all.
