on December 9, the first "optical storage and charging" integrated charging pile (hereinafter referred to as "optical storage and charging") in Huanggang City, Hubei Province was officially put into operation in the public parking lot of the municipal government affairs center

in the past two years, the eye-catching headlines of "the first in a province" and "the first in a city" have been used in the reports about the operation of "optical storage and charging" all over the country. The intensive launch gives people the impression that the development of "optical storage and charging" seems to have ushered in a small climax

what is "optical storage and charging"? Why focus on delivery? What challenges will we face in the future

recently, a staff member in Wuhan, China, told that "optical storage and charging" is a high-tech green charging mode that converts solar energy into electric energy through photovoltaic systems and stores it in the energy storage system, and then charges electric vehicles. It is also a coordinated support of new energy, energy storage, and intelligent charging

however, during the field visit for nearly two hours, there was no car to charge. The above staff admitted that it was really difficult to make a profit now

many employees from energy storage, photovoltaic power generation and charging pile enterprises also said to, "at present, the 'optical storage and charging' is only a demonstration operation." the 'optical storage and charging' still has many problems, such as photovoltaic power generation, high capacitance, high energy storage cost, untimely use of battery echelons, sluggish development of electric vehicles, and no policy support

On December 9, the first "optical storage and charging" integrated DC fast charging station in Huanggang City, Hubei Province was officially put into operation in the public parking lot of the municipal government affairs center. The integrated charging station can convert solar energy into electric energy, and has the functions of charging and energy storage. It can provide charging services for private cars, buses, car hailing and other electric vehicles

the search found that the "optical storage and charging" in Songjiang, Shanghai, which was put into operation in October 2017, was one of the earliest in China. In 2018, at least 15 "optical storage batteries" were successively put into operation. So far, at least 36 "optical storage and charging" have been put into operation nationwide, and at least four urban areas in Wuhan, Xi'an, Quanzhou and Yuhang District of Hangzhou have been put into operation in October this year alone

in addition, the eye-catching headlines of "the first in a province" and "the first in a city" have been used in the reports about the operation of "optical storage and charging" all over the country. The intensive launch gives people the impression that the development of "optical storage and charging" seems to have ushered in a small climax

what kind of upstart is "optical storage and charging" so that so many places and enterprises have invested in it

according to the data, "optical storage and charging" refers to the charging pile integrating "photovoltaic + energy storage + charging". It is an application of micro electricity, and it is also a new business model generated under the background of the country's vigorous promotion of electric vehicles, the expansion of the charging pile Market, and the inclusion of energy storage in major projects of energy development

data show that by November 2019, the number of charging piles in China has reached 1.174 million, and according to the national development goals, the total number of charging piles in China will reach 4.8 million in 2020, which is far from the goal

in July 2017, the outline of the 13th five year plan for national economic and social development of the people's Republic of China clearly listed "promoting the construction of demonstration projects of energy storage power stations and strengthening the integration and complementarity of multiple power sources and energy storage facilities" as a major project of energy development

in July 2019, the national development and Reform Commission again issued the "notice on printing and distributing the annual action plan for implementation", proposing to realize the transition of energy storage from research and development demonstration to the initial stage of commercialization during the "13th five year plan"; During the "14th five year plan" period, we will realize the transformation from the initial stage of commercialization to large-scale development. According to the research and statistics report released by iResearch consulting, by the end of 2019, the market size of China's public charging service industry may exceed 15billion yuan. It is estimated that by 2020, the market size may reach more than 20billion yuan, and the charging service market has great potential

under the circumstances that the subsidy of charging pile is declining and energy storage has become an established policy, the combined business model of "light storage and charging" seems to have great development prospects

"for example, in a big city like Beijing, its resources are so dense that it will be impossible to get off in a few years to lead a large-capacity power line from the outside to ZhongGuanCun, and it is not certain whether it will be approved or not. You have to find a way to solve it yourself, 'storage and charging alone' should be born." Guo Chao (a pseudonym), who is responsible for the market research and analysis of Xinwangda technology and front-end, said

muxiaopeng, director of electrical technology and vice president of the Technology Research Institute of teday new energy Co., Ltd., Professor jixuehong of Northern Polytechnic University, and Li Xiangzhe, head of the technology center of Suzhou Anyun power supply Co., Ltd., all said that "optical storage and charging" is a trend, but they also said that "optical storage and charging" still has photovoltaic power generation, high capacitance, high energy storage cost, untimely use of battery echelons, sluggish development of electric vehicles There are no many problems such as policy support

China, as the first largest country of new energy vehicles, has a profit problem: it takes six years for a charging station to return to its original cost

Wuhan, 100 kilometers away from the "optical storage and charging" of Huanggang City, also put into operation the first "optical storage and charging" in Hubei Province on October 16. Recently, I saw its true face in the courtyard of guowuhan company at Chuangye road in Zhuankou economic development zone

when entering the hospital, the first thing you see is two charging parking spaces and a 60 kW dual gun integrated DC charging pile of Shenzhen Shenghong electric, which also says "Dongfeng travel designated charging point". A few steps away, there are six 60 kW single gun DC charging piles

according to a national staff member, 16 kW photovoltaic panels are installed on the ceilings of the two charging points, and the photovoltaic modules are 32 500W flexible films, with a power generation efficiency of 16.7%. On the roof of the company, there are 64 kW photovoltaic panels, and 60 900W monocrystalline silicon modules, with a power generation efficiency of 19.3%, with a total annual average power generation of 88000 kwh

next to the single gun charging pile are the distribution box, transformer cabinet and energy storage cabinet, which can store 215 kwh of electricity. The charging guide beside the charging pile also indicates the charging price, which is 1.25 yuan/kWh at peak time, 1.20 yuan/kWh at normal time and 0.90 yuan/kWh at valley time

the staff member also said that by converting solar energy into electric energy and storing it to charge electric vehicles, six DC chargers are powered by municipal electricity. Only this two gun integrated DC charger is powered by distributed photovoltaic power generation and energy storage devices. It takes only 45 minutes to fully charge an ordinary electric vehicle

"it ('light storage and charging') stores energy when the electricity price is low at night, and supplies power to the charging station through energy storage and municipal power during the peak charging period, which not only realizes peak shaving and valley filling, but also saves the cost of power distribution and capacity increase, increases the consumption of new energy, makes up for the lack of continuity of solar power generation, and is a sustainable energy utilization mode." Ji Xuehong said

however, after observing this charging station for more than two hours, no car came in to charge. The guard said that there were not many electric cars in Wuhan, and most of them were from Dongfeng. However, this place is a little biased, and there are not many people coming to charge. The staff of the country also said that at present, there are not many cars charged, and it is difficult for the power station to make profits

in this regard, pan Yongqiang, marketing director of Shenzhen yingweiteng Electric Co., Ltd., said, "now 'optical storage and charging' is only a demonstration operation". Optical storage and charging stations complement each other, which is directly related to the number of charging stations and the number of new energy vehicles. Only when the number of vehicles is large enough, can 'optical storage and charging' be profitable. "

Wang Peng (a pseudonym), the relevant technical director of a domestic intelligent charging technology and facilities company, said that at present, there are few subsidies for photovoltaic power generation, charging piles and energy storage systems. For example, there are almost no subsidies for AC charging piles. A better DC pile costs 50000 or 60000 yuan, and a cheaper one costs about 30000 yuan

he also calculated that lithium batteries cost two yuan a watt hour. To build a charging station that requires at least 500 kilowatt hours, it will cost more than 1 million yuan. At any time, a "light storage and charging" will cost tens of millions of yuan. It will take at least six years to get back by power generation and charging alone

"at present, the use of echelon batteries is still advocated in the energy storage industry, but the service life of retired power batteries is only four to five years. Before returning to the original, the batteries have to be replaced. Now they are all new batteries, and echelon batteries are still far from application." Pan Yongqiang said, "there are few charging piles that can make profits. With so many costs, it is even more difficult to make profits."

there are still many problems, and the key to solve the problem is electricity

compared with the problem of cost and technology, photovoltaic power generation is the main problem

muxiaopeng said that although "optical storage and charging" is still in the demonstration stage, there should still be great application scenarios in the future. With the decline of battery cost and the continuous improvement of efficiency after technological progress, it will gradually produce economic benefits

"there is no technical problem, and there is no charging station connected to optical storage. It is only a matter of approval and standards to connect photovoltaic power generation and energy storage equipment." Guo Chao said that in addition, the merger of electricity prices will inevitably lead to interest disputes in the future

from a commercial point of view, Wang Peng said that the current "optical storage and charging" still belongs to the category of distributed energy and energy trading. As the core carrier of energy trading, China is the terminal and pricing power of energy trading. Because China has built several "optical storage and charging", other interested parties such as Hefei Hanxing Energy Storage Technology Co., Ltd. and Yunnan Dianzhong Huineng Smart Energy Co., Ltd. are also willing to participate

according to incomplete statistics, there are at least 36 "optical storage and charging" that have been put into operation nationwide. In March and April 2018, after the "optical storage and charging" of Liuhe service area in Nanjing and Jiaxing in Zhejiang, which are dominated by State Grid, was put into operation, "optical storage and charging" will "blossom everywhere". In 2018 alone, at least 15 "optical storage and charging" stations in China were put into operation

although "optical storage and charging" have been put into operation, many people are not optimistic

"'optical storage and charging 'still depends on electric vehicle V2G technology, which is the real big market and direction." Hu Zechun, a researcher on energy interconnection at Tsinghua University, said

v2g is the abbreviation of vehicle to grid. When the electric vehicle is not in use, the electric energy of the on-board battery is sold to the electric system. If the on-board battery needs to be charged, the current will flow from the current to the vehicle

Wang Peng said that V2G is a very important unit for mobile energy storage of private car owners, and the technology is not difficult, but it is too difficult to implement. If everyone discharges and charges at the same time, it will have a great impact on the distribution and adjustment of electric load. In summer and winter, the electricity will run at full load. In this way, it is difficult to measure the spectrum emitted by its materials in many places, and it will have a great impact on electricity if V2G is made again

Hu Zechun believes that the demand for charging is bound to increase, and the prospect of new energy vehicles is also very good, but he does not think that "light storage and charging" will be a very mainstream model, "the area of big cities is very limited,
