Grasp the 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
according to public data, at the end of 2012, China had 18000 public charging piles, and at the end of 2014, China had 31000 AC and DC charging piles. 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 reached 115.7% and 185.3% respectively. This was also the two years when the charging pile was the "highlight" 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 alliance, 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. In February this year, affected by the epidemic, the pile building business basically stopped. However, even so, by 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 the current vehicle pile ratio is 3.5:1, that is, 3.5 vehicles share a charging pile, which is difficult to meet the needs of consumers
liuyongdong, director of standardization management center of China Electricity Council and Secretary General of Standardization Technical Committee of electric vehicle charging facilities in energy industry, gave suggestions on charging pain points and trends
charging pain points to be solved
although China has made great achievements in the construction of charging facilities, the industry has also exposed a series of problems, mainly reflected in:
from the perspective of operators, the business model of charging services has not been clear, and charging services alone as the main revenue business model is far from supporting the sustainable development of the heavy asset charging service market. Charging service operators have been plagued by difficulties in finding the place, high costs and special power supply problems of charging stations for a long time. 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 entrances, but the practicability is insufficient, and it is difficult to find charging piles with good performance and no space occupied by oil vehicles; The charging demand for special models such as rental, sharing and logistics can not be met, and the advantage of low use cost of electric vehicles has not been fully reflected
from the perspective of equipment manufacturers, the charging equipment market is fiercely competitive. Without the formation of 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 a hidden danger for the 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 primary stage of development, which belongs to the extensive development of "horse racing enclosure", and needs continuous industrial upgrading and rapid iteration of technology
convenience, intelligence and two-way interaction become the trend
smart transportation, smart city and smart TV field, and charging facilities are facing new challenges. As a new urban infrastructure, electric vehicle charging facilities are an important part of the smart city; As the provider of energy supply for electric vehicles, the charging facilities are facing the transformation and development of new energy vehicle technology characterized by electrification, integration, 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 taken into account 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 under 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 difference in the planning and layout of the thermoplastic polyurethane (TPU) electric facilities invented by CBRC; The charging demands 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. Exploration and full competition should be allowed. The final technical route should be determined by the market and guided by the government
second, develop new charging solutions that are fast, convenient and intelligent. The principle of "user first" shall be adhered to. Charging service experience, charging service quality and charging safety will become the assessment indicators for the construction and development of charging market in the next step. To improve charging service experience, improve charging service quality and ensure charging safety, analyze and grasp the next development trend of charging technology. Shortening the charging time requires us to vigorously develop high-power charging technology; Non inductive charging experience and simplified 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
the third is to combine 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, networking and intelligence. 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. Standing at the height of smart transportation and smart cities, charging facilities should be more closely combined with the construction of urban transportation facilities, electric facilities and urban planning, coordinate the demand for vehicle flow, people 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 provider should transform into an energy system provider. It should not only participate in the power demand response as a load provider, but also become an energy provider. Through virtual power plants, it can enter the power market and participate in power transactions, so as to achieve a magnificent turn of identity as an operator
fifth, deeply participate in international standardization from an international perspective. As an industry with distinctive international competitive characteristics, electric vehicles make it impossible for us to develop charging facilities in isolation. 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. International standardization will play an increasingly important role in future international market competition. This requires us to not only pay attention to the introduction of international advanced standards, but also actively participate in International standardization, strive to contribute to China's technical solutions, and bring Chinese technology into international standards, Providing technical solutions for charging facilities
