Grasp five trends and solve the charging pain points of charging facilities of electric vehicle charging stations

as a strategic emerging industry in China, electric vehicles have made major breakthroughs after nearly 10 years of efforts

public information shows that at the end of 2012, the number of public charging piles in China was 18000, and at the end of 2014, the number of AC and DC charging piles in China was 31000. Since then, in 2015 and 2016, affected by the large-scale popularization of new energy vehicles and relevant policy support, the growth rate of public charging pile ownership was as high as 115.7% and 185.3% respectively. This is also the two years of the most "highlight" of charging piles in the capital market. After that, the annual growth rate of the number of charging piles slowed down, but the annual year-on-year growth rate still exceeded 50%

according to the data of China charging Union, by the end of January 2020, 531000 public charging piles and 712000 private charging piles had been built nationwide, with a vehicle pile ratio of about 3.5:1. However, affected by the epidemic in February this year, the pile building business basically stagnated, but even so, as of February 2020, the cumulative number of charging infrastructure in China was 1245000, an increase of 43.8% year-on-year

according to the development guide for electric vehicle charging infrastructure (), by 2020, China will build 4.8 million charging piles to meet the charging demand of 5million new energy vehicles, including 500000 decentralized public charging piles and 4.3 million private charging piles. At present, the public charging piles have reached the planning requirements in advance, but the number of private charging piles is still far from enough. In addition, according to the plan, the vehicle pile ratio is about 1:1, but at present, the vehicle pile ratio is 3.5:1, that is, 3.5 vehicles share a charging pile, which is difficult to meet the needs of xiaocorkgel, an innovative material consumer of selle Royal

Liu Yongdong, director of the standardization management center of the China Electricity Council and Secretary General of the Technical Committee for standardization of electric vehicle charging facilities in the energy industry, gave suggestions from the aspects of charging pain points and trends

charging pain points to be solved

although the construction of charging facilities in China has made significant achievements, the industry has also exposed a series of problems, mainly manifested in:

from the perspective of operators, the business model of charging services is not clear, and relying on charging services as the main revenue business model is far from supporting the sustainable development of the heavy asset charging service market. Charging service operators have long been plagued by difficulties in finding places for charging stations, high costs, and special power supply problems. Structural scarcity caused by unreasonable planning and layout of charging facilities and low utilization of public charging piles coexist. Events such as fire caused by electric vehicle charging also affect the confidence of all parties

from the perspective of car owners, poor charging experience is the main deficiency. It is difficult to build private piles in the community, and there are hidden risks; The charging interconnection is insufficient, there are too many software entries, but the practicality is insufficient, and it is difficult to find a charging pile with good performance and no space occupied by the tanker; The charging demand for special models such as rental, sharing and logistics cannot be met, and the advantage of low cost of electric vehicles has not been fully reflected

from the perspective of equipment manufacturers, the charging equipment market is fiercely competitive. Without forming a blue ocean, many participants have flocked to form a red ocean. The phenomenon that bad money drives out good money still exists, causing the quality of charging equipment to be worrying, and laying hidden dangers for long-term safe and reliable charging in the future

from the perspective of power companies, although the charging power of slow charging is low, there are also uncontrollable factors such as charging time and location. The capacity expansion and reconstruction of old residential areas are subject to space and cost constraints. The large-scale application of charging facilities will inevitably bring new challenges to the planning and development of electricity

these problems show that the development of electric vehicle charging facilities in China is still in the initial stage of development, which belongs to the extensive development of "horse racing enclosure", and it also needs continuous industrial upgrading and rapid iteration of technology

convenience, intelligence and two-way interaction are becoming a trend.

smart transportation, smart city and smart TV are facing new challenges for charging facilities. As a new urban infrastructure, electric vehicle charging facilities are an important part of smart cities; As the provider of electric vehicle energy supply, charging facilities are facing the transformation and development of new energy vehicle technology characterized by electrification, interconnection, intelligence and sharing by using the principle of thermal equilibrium and circular mixing mode; At the same time, as an important object of smart electricity application, charging facilities also need to be considered in smart electricity integration. Next, the development of charging facilities should grasp the following trends:

first, establish a three-dimensional charging service network system to meet different charging needs. We should adhere to the technical route of market-oriented development of charging facilities. China's national conditions determine the diversity and complexity of China's electric vehicles and charging facilities. The national unified charging technical route can not meet the charging needs of various charging scenarios. The different charging needs of private cars, taxis, logistics vehicles and buses lead to different charging technical routes; The different charging demands between the first tier cities and the second and third tier cities have led to the differences in the planning and layout of the thermoplastic polyurethane (TPU) electric facilities invented by fullrich; The charging needs of high-end brands and Volkswagen ordinary brands are also different, which brings different adaptability of different charging technologies. Conductive charging, wireless charging and battery replacement all have their own market segments, which should allow exploration and full competition, and the final technical route should be determined by the market and guided by the government

second, develop fast, convenient and intelligent new charging solutions. We should adhere to the principle of user first. Charging service experience, charging service quality and charging safety will become the assessment indicators for the construction and development of the charging market in the next step. The next development trend of charging technology should be analyzed and grasped with the goal of improving charging service experience, improving charging service quality and ensuring charging safety. Shortening the charging time requires us to vigorously develop high-power charging technology; The experience of non inductive charging and the simplification of unified charging interface require us to develop wireless charging technology and low-power charging technology; To realize cross platform charging, we need to establish a charging roaming interconnection technology system; Safe and reliable charging requires us to strengthen charging electrical safety, information security and other technologies. Faster, more convenient and more intelligent charging experience will be the development trend of charging technology in the next step

third, we should integrate charging facilities with the development of electric vehicles, smart transportation and smart city construction. As the power supplier of electric vehicles, charging needs to be combined with the development trend of electrification, interconnection and intelligence of vehicles. When electric vehicles have been able to drive automatically, automatic charging will also become a standard configuration. As a part of the city's energy system, charging facilities should also play an important role in the construction and development of smart cities. It is necessary to stand at the height of smart transportation and smart cities, integrate charging facilities more closely with the construction of urban transportation facilities, electric facilities and urban planning, coordinate the needs of vehicle flow, pedestrian flow, parking and charging, and scientifically and reasonably arrange charging facilities

fourth, vigorously develop the two-way interactive technology of electric vehicle charging and discharging, and redefine the positioning of charging service operators. We should develop charging facilities under the framework of the energy system. We should not only treat the charging of electric vehicles as an energy load, but also treat the discharge of electric vehicles exempted by the European Union, Canada and Mexico as an energy provider. To bring the charging and discharging of electric vehicles into the scope of energy services, the current electric vehicle charging service providers should be transformed into energy system providers, not only as load providers, participating in power demand response, but also as energy providers. Through virtual power plants, they can enter the power market, participate in power transactions, and realize the gorgeous transformation of the identity of operators

fifth, deeply participate in international standardization with an international perspective. As an industry with distinctive characteristics of international competition, electric vehicles cannot be closed and self-locking in the development of charging facilities. With the enhancement of the strength of China's electric vehicles and charging facilities in recent years, Chinese enterprises have accelerated their entry into overseas markets, and international standardization will play an increasingly important role in the future international market competition. This requires us to not only pay attention to the introduction of international advanced standards into the adoption of standards, but also actively participate in international standardization, strive to contribute to China's technical solutions, and integrate Chinese technology into international standards, Become the provider of technical solutions for charging facilities
