At present, even in the first-tier cities, the construction coverage of electric vehicle charging facilities is still not ideal.

Standards need to be unified

Nowadays, pure electric vehicles have evolved from the original power-changing mode to the charging mode, and have developed from slow charging to fast charging, which is closer to the needs of customers and closer to the market. However, the major electric vehicle companies have not unified the battery performance and specifications, and even the gap is very large. In the case of slow charging, Tesla offers a dedicated wall-mounted adapter; BYD Daimler New Technologies utilizes ABB's DC fast charger and also has a super charging tower; BMW also chooses Cooperation with Schneider. In short, the car companies are in a system.

As a result, the lack of technical standards has become a problem before the promotion of electric vehicle charging facilities. If you use a charging device that does not match your own voltage standard, even if you can charge it, it will affect the battery life of the car. It is also known that the charging piles designed by most car companies themselves cannot be used for other brands of electric vehicles. Therefore, although some first-tier cities have begun to build new energy vehicle supporting facilities, it is not easy to implement large-scale implementation.

"The lack of relevant standards and specifications such as current and voltage is still the main weak link in the promotion and application of electric vehicles, which brings great difficulties to the next development of electric vehicles and the unified planning of charging facilities." Perhaps only solved This problem, new energy vehicles can run faster and further.

Lack of charging facilities

As we all know, charging piles are the most important supporting facilities for electric vehicles. The improvement and promotion will directly determine whether new energy vehicles can be fully rolled out. The lack of current charging facilities has also become an urgent problem to be solved in the promotion of new energy vehicles in China.

Taking Beijing as an example, in Beijing, the electric vehicle charging and exchange management service platform shows that the charging piles that can be opened to the public are quite sparse. Among the 16 districts and counties, there are no public charging piles in the two core areas of Dongcheng and Xicheng. Mentougou, Pinggu, Huairou, Miyun and Yanqing are also blank areas of public charging piles. The relatively large number of charging outlets are Haidian District, Chaoyang District and Fengtai District. There are 10, 7 and 5 rechargeable outlets respectively, most of which are automobile 4S shops. The location is mostly in the Wuhuan area.

According to the plan, Beijing will complete the construction of 1,000 fast-charging piles by the end of 2014, and initially build a 5km radius fast charging network in the Fifth Ring. However, in the past six months, in addition to the charging piles of 4S shops, there are few charging piles in other public areas open to the public. In the face of charging problems, Beiqi New Energy Co., Ltd. will set up a charging business unit to explore countermeasures.

Accelerated icebreaking pace

However, the above problems are already being resolved.

On July 8 this year, German Chancellor Angela Merkel and China’s Minister of Industry and Information Technology, Miao Wei, attended the launch of the “Sino-German Electric Vehicle Charging Project” and launched a demonstration demonstration of a total of 8 electric vehicles in China and Germany. Both can use a unified charging facility, which also indicates that the electric vehicles in China and Germany have adopted a unified communication standard for AC charging facilities. It can be seen that the charging standards for China's new energy vehicle market are expected to be unified soon.

In addition, the state is also accelerating the construction of charging pile supporting facilities. According to Shen Jianxin, deputy director of the marketing department of the State Grid Corporation of China, at present, China has built 600 charging and replacing stations and 26,000 charging piles. By 2020, the State Grid plans to build 6,237 replacement and power stations, 156 charging towers and 670,000 charging piles. This year, the State Grid plans to complete the layout of charging outlets on all highways.

Major cities such as Beijing, Shanghai, and Shenzhen have also accelerated the pace of supporting charging construction. The government of Beijing and Shanghai has introduced a subsidy program for charging infrastructure. Taking Beijing as an example, 100 fast-charging piles and 300 slow-speed charging piles have been completed. In the near future, the construction of 500 fast-charging piles in 50 parking lots will be started, and 1000 fast-charging piles will be completed by the end of this year. The construction will be able to meet the rapid charging of 24,000 new energy vehicles at the same time, and build a 5km radius fast charging network in the Fifth Ring to solve the "mileage anxiety". Recently, on the eastern section of Jingmi North Road near the Nanshao Station of the Changping Line of the Metro, the first batch of streetlight charging piles in the city has been “on the job”.
