Charging pile is currently facing the problem:
1.Difficult to charge
By the end of last year, the number of charging piles reached 450,000, an increase of 51% year-on-year, but still far from meeting the demand for electric vehicle charging. Although the increase in the range of vehicles has eased the problems of charging, the overall situation has not fundamentally changed and the difficulty of charging is still prominent.
2. Low utilisation rate
At present, many cities have polarized differences in the utilization rate of public charging piles in different areas, for example, in the same city, the utilization rate in some areas can reach 70%, while some areas are low. By the end of 2017, China's public charging pile utilization rate is less than 15%, and some charging piles have even become zombie piles. Due to the initial "horse race", many companies did not consider the market demand when building piles, but only focused on grabbing land and expanding market share. Some charging piles were installed in remote areas, even in the fields, so the number of charging piles was not as high as it should be.
3. Unbalanced layout
The location of charging piles needs to take into account factors such as the density of customer flow and usage rate, which makes public areas such as superstores, schools, hospitals and tourist attractions a favoured target for charging pile companies. Most regions have a fixed number of construction projects, but the main areas are still in the Beijing-Tianjin region, the eastern coast, the southeastern coast and the middle and lower reaches of the Yangtze River, and there are still relatively few construction areas in the west and north. Statistics show that the utilization rate of charging piles in the urban areas of North, Shanghai and Guangzhou reaches 70%, but the utilization rate of second and third-tier cities is low. In addition, some of the relevant enterprises operating mode for the equipment and operation of the dual mode, which led to the waste of some resources and some maintenance and repair of the situation is not in place.
Second, the current charging pile construction problems
1.Land
At this stage of urban land supply is known to be tight, large-scale construction of charging stations will take up valuable land resources, and many cities have no large areas of land for the planning and construction of charging stations, if you consider taking up urban green space, which itself is contrary to the starting point of the development of new energy vehicles, and charging station construction itself to meet the "three through flat "Therefore, the land factor is fatal to the construction of stations, and it is not feasible to build charging stations on a large scale.
2. Cost
Investment in the construction of charging stations requires a lot of money, for example, the State Grid's charging station investment will cost hundreds of millions of dollars, and the construction cycle is long, after the input, to face huge losses in the early stage, according to the State Grid insiders, has been built more than 400 charging stations almost no profitable projects, in the line loss state; according to the Southern Power Grid branch of the statement, its completed in Shenzhen to operate the seven charging stations, the annual The loss is 13 million yuan. Secondly, charging stations need to be equipped with a large number of charging guards, which can lead to high operating costs, while high labour costs and low efficiency.
3. Service capacity
At present, due to the performance of the power battery, it takes 2-3 hours to charge in fast charging mode, so most charging stations are configured in accordance with the pile-to-vehicle ratio of 1:3 or 1:4, and even if a charging station is equipped with 30 chargers, it only serves less than 100 vehicles, not to mention that most charging stations are equipped with about 10 chargers, and the number of service vehicles is even smaller, while the daily service capacity of a gas station of the same size is less than 100 vehicles. The daily service capacity of a petrol station of the same scale can reach thousands of vehicles, so the utilisation rate of a charging station for less than 100 vehicles is pathetically low.
4. Convenience
In some public bus areas, after the vehicle has finished running, it needs to go to the charging station again to replenish the electricity, which itself increases the tediousness of charging, and in the process of moving the car is easy to collide with the charging station building or equipment, the whole charging process seems very inconvenient.
Three, charging pile construction station solutions
1, since there are many problems in the charging station construction, we need to think differently, in the charging infrastructure, the important equipment is the charging pile, we can transform a charging station into a number of charging piles for distributed construction, so that the distributed construction of the charging pile has the advantages of less land occupation, low cost, short construction cycle can be fully demonstrated, to avoid the traditional charging station to build the station All kinds of defects.
2. At this stage, in the process of promoting new energy vehicles, the target customer groups are relatively fixed, mainly concentrated in public transport areas, specific industry sectors and some private cars, and their operation rules, usage habits, parking locations and times are regular. For example, Tesla has adopted the mode of destination charging in the construction of charging infrastructure, making the layout of charging infrastructure closer to users and achieving very good results.
Even if the charging piles need to be relocated, it is much easier than relocating the charging stations and the reuse rate of the equipment is also high, which somehow reflects the local government's new energy promotion programme that mentions This also reflects to some extent the requirement of "piles follow the vehicles" mentioned in the local government's new energy promotion programme.
4, distributed charging pile group construction to emphasize the concept of network, the first may be a few points, as users increase, the scale of expansion, from point to point, the formation of a city service network, which is the future of the ecological structure of urban charging infrastructure, of course, whose network is built early, large scale, high service level, who will take the high ground of the future industry domain.
5. As the distributed charging pile group has the characteristics of unattended and user self-service operation, the charging pile needs to have high security, friendly operation interface and intelligent service, and needs to be equipped with monitoring platform and operation and maintenance team, which are important functions that the distributed charging pile group network needs to have.
In the construction of charging infrastructure, we need to think innovatively, use limited resources to meet user needs, provide energy solutions from the user's point of view, gradually transition from personalised needs to common needs, and then build up an urban charging infrastructure service network, in this process, build piles to meet user needs, in fact, do not need to invest too many resources for no use of charging stations In fact, there is no need to invest too much resources in the construction of charging stations that are not used at all, so don't run away from the construction of charging infrastructure.
