On July 8, German Chancellor Angela Merkel and Miao Wei, minister of the Ministry of Industry and Information Technology of China, jointly worked together at Tsinghua University to represent the handle of the Sino-German electric car cooperation project. The electric car charging project was officially launched.

According to the cooperation agreement, in the future, China and Germany will achieve complete reunification of the charging interface standard. Both parties will also sign a charging communication agreement and finally realize the full sharing of charging facilities. However, although electric vehicles in China and Germany are able to charge one charging pile, they are of no value in practical applications because the electric charging cars currently installed by the State Grid Corporation of China in accordance with China's standard German standards are charged Can only achieve slow charge, but not fast charge.

In an interview with China's First Financial Daily, a German expert said: "If China and Germany can reach an agreement on charging standards, it will have a significant impact on the future charging standard for electric vehicles." He said that China is the future The world's most important consumer of electric cars, while the German car manufacturing is very advantageous. But the standard docking and unification is not easy.

On the afternoon of July 8, the Sino-German electric vehicle charging project communication meeting was held at Tsinghua University. The German government and business experts attending the communication meeting paid great attention to China's public charging facilities standards. Shen Jianxin, deputy director of marketing department of State Grid Corporation of China, said that China has its own charging standard and hopefully the world can have a unified charging standard in the future. However, before that, all the electric car products that enter China are expected to be charged by China's electric car Standard, but it is also necessary. "

Electric car charging standards mainly from the power and interface standards. Shen Jianxin said in an interview with this reporter said that the reason why China has been the layout of the charging pile can not meet the rapid charge of foreign-funded electric vehicles, mainly the charging interface standards on both sides are not the same.

In the charging interface, at present, there are mainly five sets of charging pile standards in the world. The first set is the standard ICE standard established by the International Electrotechnical Commission, the second is the SAE standard established by the American Society of Automotive Engineers, the third set is the European Automotive Industry The ACEA standard proposed by the association, the fourth set is the CHAdeMO standard introduced by the Japan Electric Vehicle Association and the Japan Electric Vehicle Charging Association. China also introduced its own standard in 2006 and released the "Electric Vehicle Charging Plugs, Sockets, Vehicles General Requirements for Couplings and Vehicle Hubs. "

As for the unified charging standard between China and Germany, an electrician who asked not to be named said "very difficult." The first is due to the national standard and Japanese standards, Tesla standards, the use of CAN BUS communications are technically relatively close, while Europe and the United States standards using PLC communications, technical differences; Second, the full implementation of European standards in 2017 in Europe However, to achieve reunification between China and Germany means that the standards of China and the EU should be unified or that the standards of the EU should be compatible with the standards of China and Germany.

Industry anonymity, industry experts told this reporter, in fact, China's charging standard is not perfect enough, GB / T20234-2011 only recommended standards, not mandatory standards; part of the key information has not been determined. Currently entering the Chinese market, electric vehicles do not have a uniform standard, not only from foreign electric vehicles, even the domestic own brand is also a set of their own standards.

Under the call of the major auto companies, these standards have now started to be revised, the new version is expected to be released next year. It is said that many of them make up the missing key parameters, but also increase the content to eliminate security risks. As for the standardization of unity between China and Germany, Wang Cheng, deputy director of the Automotive Research Center of China Automotive Technology Research Center, said in an interview with this reporter: "At present, both China and Germany have started to carry out research on the construction of their own charging facilities. Based on the unified charging interface standard will be determined. "

Although both Chinese and foreign experts attending the Sino-German EV charging project hope that a practical solution will be put in place for the second meeting in October this year, what standards should be used by the auto companies in this process and how they should be put into consideration? To the market of electric vehicles, both did not give a clear solution.
