Electric vehicle system charging is still "big problem"

Beijing Tsinghua Science Park is located in the charging outlets. At present, even in the first-tier cities, the construction of electric vehicle charging facilities is still not ideal.

Standards need to be unified

Today, the pure electric vehicle has been developed from the original mode of electricity-charging mode, and from slow-charge development to the rapid charging, more close to customer demand, but also closer to the market. However, the major electric vehicles in the battery performance, specifications and other aspects are not unified, or even a large gap. For example, Tesla offers a dedicated wall-mounted adapter; BYD's new technology company, which uses ABB's DC fast-charging machine, also created its own super-charging tower, and BMW chose to work with Schneider. In short, the car enterprises into a system.

In this way, the technical standard is not unified in the electric vehicle charging facilities before the marketing of a problem. Charging devices that do not match their own voltage standards will have an impact on the battery life of the vehicle, even if they are able to charge. It is also understood that by the majority of car companies themselves involved in the design of the charge pile, and many can not be used for other brands of electric vehicles. Therefore, although some front-line cities have started to build new energy vehicles supporting facilities, it is not easy to implement a large area.

The lack of relevant standards and norms, such as current and voltage, is still the main weakness of the application of electric vehicles, which brings great difficulties to the development of electric vehicles and the unified planning of charging facilities. "Perhaps the only way to solve this problem is for new energy vehicles to run faster and farther," he said.

Lack of charging facilities

As we all know, charging pile as the most important supporting facilities of electric vehicles, its improvement and promotion will directly determine whether new energy vehicles can be fully rolled out. At present, the shortage of charging facilities has become an urgent problem to be solved in the promotion of new energy vehicles in China.

Taking Beijing as an example, in Beijing electric vehicle charging management Service platform, shows that can be open to the public charge pile outlets are quite sparse. In 16 counties, not only the east and west side of the two major core areas without public charge piles, Mentougou, Pinggu, Huairou, Miyun, Yanqing is also a public charge pile blank area. A relatively large number of charging outlets are Haidian District, Chaoyang District and Fengtai District, respectively, there are 10, 7 and 5 rechargeable outlets, most of them are car 4S shop, the location of the five-ring area mostly.

According to the plan, Beijing will complete 1000 fast charging piles by the end of 2014, and construct a 5 km fast charging network within five rings. However, in the past six months, in addition to the charging pile of 4S stores, there are few charging piles open to the public in other public areas. In the face of charging problems, baic New energy company will set up a special charge division to explore countermeasures.

The pace of ice breaking accelerates

However, the above problems are already being resolved.

On July 8 this year, German Chancellor Angela Merkel and China's Ministry of the Treasury, Wei, attended the launch of the Sino-German electric vehicle charging program, which launched a charging demonstration device for a total of 8 electric vehicles in the two countries, which could use a unified charging facility, It also marks the adoption of a unified communication standard for AC electric charging facilities in both China and Germany. This shows that China's new energy vehicle market charging standards are expected to soon be unified.

In addition, the state is also speeding up the construction of ancillary facilities for rechargeable piles. According to Shen Jianwei, deputy Director of marketing Department of State Grid company, we have built 600 power stations and 26,000 charging piles at present. By 2020, the State Grid was planned to build 6,237 rechargeable power stations, 156 charging towers and 670,000 rechargeable piles. This year, the National Grid plans to complete the distribution of the charging outlets on all highways.

BEIJING, Shanghai, Shenzhen and other major cities have also accelerated the pace of construction of rechargeable piles, Beijing-Shanghai and other governments have launched a subsidy scheme for charging infrastructure. Taking Beijing as an example, the construction of 100 fast charging piles and 300 slow charge piles has been completed, and the construction of 500 fast charging piles in 50 parking lots will be started in the near future, by the end of this year, the construction of 1000 fast charging piles is completed, will be able to meet 24,000 new energy vehicles at the same time fast charging, in the five-ring built 5 km radius fast charging network to solve the "mileage anxiety." Recently, in close to the subway Changping Line South Shao station of Beijing-North Road East section, the city's first street lamp charge pile has been "induction" operation.
