Internet pioneer Kevin Kelly once said that no matter what industry you are doing, the most serious threat to you must not be in the industry, but you can not see those outside the industry competitors.While the industry is still debating, Whether the charging pile should be placed in the traditional gas station in the future, in order to resolve the biggest bottleneck in the electric vehicle industry, the world's first photovoltaic highway was opened to traffic in Jinan, Shandong Province.
Although the project is still undergoing pilot phase, the technical roadmap for the next three years is to realize the mobile charging of vehicles, turning the whole highway into a huge charging pile.
Forced reforms
'The future' Super Highway 'will be both a' power plant 'and a huge' charging pile. 'On December 28, 2017, Qilu Traffic invested in the project for the opening of the first photovoltaic expressway in the world Xu Chunfu, chairman of Development Group (hereinafter referred to as 'Qilu Traffic'), said.
The 'Super Highway' pilot section is located on the south lane of the Ring Expressway in Jinan, with solar photovoltaic panels laid on the main and emergency lanes. The project started in December 2016 with investment from Qilu Transport and together with Tongji University , Shandong Light Energy Co., Ltd. for technical research and development.
Xu Chunfu introduced that the total length of the PV high-speed pavement is 1120 meters and the total net area for paving is 5,875 square meters, showing a grayish color different from other expressways. According to the calculation, the peak power of the installed capacity of the distributed PV grid-connected power generation is 817.2 kilowatts, Annual generating capacity of about 100 million kwh.
As a traditional expressway operator, Qilu Transportation Development Group is the first water test taker in the world, and one participant admitted frankly that behind this innovative exploration, it is really a forced reform.
In order to ensure technical applicability, Qilu Traffic has constructed a 160-meter common pavement demonstration area in September 2017 for a series of application-oriented tests.The top layer of this high-speed photovoltaic pavement is a frosted translucent new material similar to frosted glass Coefficient higher than the traditional asphalt pavement to ensure that the tire does not slip at the same time, but also has a high transmittance, allowing sunlight to penetrate it, so that the following solar cells to light energy into electrical energy, real-time transmission on the grid, as a huge Charging treasure.
As we all know, the car can not do without the two elements of road and energy.At present, the world to expand the car's intelligent, electrified space, have explored the road and energy solutions for the integration.At the end of 2016, in a small town in Normandy, France , 2.8 meters wide, 1,000 meters long the world's first solar cell highway has been put into trial operation.
'The French project is only applied to light vehicles such as passenger cars on narrow roads. We consider the need for large-scale promotion in the future, and this time it is laid on the freeway for use on the main lane including heavy vehicles such as trucks.' ' Li Wu, chairman of Shandong Guangsheng Energy Co., Ltd., which provides technical support, said that after eight years of research and development, photovoltaic pavement has matured as a cross-border technology and its design life, mechanical parameters, road performance and other indicators are all high Existing asphalt concrete pavement.
Qilu Traffic Development Group was established on July 1, 2015, with 3409 km of operation and management highway, accounting for 60% of the total mileage of expressways in Shandong Province with a total asset of RMB220 billion. In the era of radical change of old and new kinetic energy conversion, Multi-kilometer highway, can only rely on tolls to live?
Once upon a time, the total mileage of the Shandong Expressway ranks among the best in the country. From 2009 to 2016, in the seven years from now, Shandong was second in the country from the second nationwide to the eighth nationwide and even surpassed by some central provinces.
At the same time, a large number of completed toll roads face the embarrassment of falling profits, losing profits and even unable to recover costs due to the substantial increase in land and labor costs and the abolition of road maintenance fees etc. In 2015, there were as many as 15 High-speed charges due to be unable to repay the loan and was forced to postpone the charges, once triggered social controversy.According to the "2016 National Toll Highway Statistics Bulletin" released by the Ministry of Transport shows that as of the end of 2016, the national toll road debt balance reached 486 million yuan, Representing an increase of 9.1% over the same period of last year. The toll revenue and expenditure gap of toll fees was as high as 414.33 billion yuan, up 30.0% over the same period of last year.
According to the public financial results show that Qilu Transportation Development Group in the first half of 2017 operating income of 5.8 billion yuan, operating profit of only 115 million in the same period in 2016 operating profit of 213 million.
According to estimates, Shandong Province, the opening of more than 5700 kilometers of highway, emergency parking belt and the outer lane of the total area of 66.96 million square meters, the future laying of pavement photovoltaic equipment power generation after the year up to 15.6 billion degrees, generating efficiency of 15.2 billion yuan, the year 15.5 million tons of carbon dioxide emission reduction, emission reduction benefits of 4.6 billion yuan, direct benefits of 19.8 billion yuan.
At present, the state requires all provinces to account for more than 30% of new energy, but nuclear power and wind power must be examined and approved at the national level while the photovoltaic industry is a rare new energy project with the approval authority. This also provides the soil for industrial innovation.
Although the PV high-speed is only 1 kilometer long, Xu Chunfu, chairman of Qilu Transportation, though it is still in the experimental phase, seems to be "a major exploratory innovation in the conversion of old and new kinetic energy in Shandong. It is a substantial integration of the transportation and new energy industries Logo, will open up new prospects for the development of China's smart traffic and green energy. '
Costly
Intelligent and electrification of the automobile industry are two major trends, and intelligent driving has always been able to unilaterally propel the automobile due to the lack of intelligent road facilities. As the road has not been electrified, the electric vehicles can only live in cities . '' Shandong Light Real Estate Co., Ltd. Li Wu, chairman pointed out that the application of high-speed photovoltaic market is expected to promote the auto industry in one of these two major trends in the process.
At first, precisely because of the electrification and intelligence of the railway, there was a miracle of China's high-speed rail that attracted worldwide attention. Nowadays, this high-speed photovoltaic test called 'Super Highway' has brought endless reverie space to the automobile industry.
Li Wu was a road engineer working for many years. In his view, the reason why the road has not been able to achieve electrification is that the transmission cost of electricity is too high. "From the power plant to the road along the long distance, from high pressure to low pressure, From DC to AC, transmission costs are often higher than in the vicinity of the construction of power plants is still higher than in the past, most of the traditional road electricity is lighting, cameras, power consumption is not high, but the loss is large, resulting in the electrification of inter-city highway has been stagnant Before
It is estimated that the price structure includes the cost of power generation, long-distance transmission costs, local area network transmission costs, transmission costs to households. Power generation and long-distance transmission each account for 30% -40%.
The industry generally believes that intelligent transportation is generally divided into three major steps: First, the electrification of roads; second is the energy and information synergy vehicles; Third, the wisdom of traffic. The stagnation of the highway electrification also dragged the intelligent traffic reform. The current road snowmelt, wireless WIFI , Big data and other technologies have matured, but can not be applied in inter-city road.
'Photovoltaic pavement technology is a technological innovation and reserve for the transportation infrastructure industry to move toward the goal of smart transportation.' 'Zhang Hongchao, a professor of Tongji University who has been engaged in the research of photovoltaic pavement for a long time, believes that in the future intelligent electric vehicles can not be separated from the electrification of roads. The supply of energy will make the road truly a space carrier, energy and information interaction platform for smart transportation.
Xu Chunfu told reporters that due to lack of security and the number of electric vehicles and other factors considered, the trial section has not yet set foot in wireless charging; but in the future will feature, mobile wireless charging, Internet coverage, big data integration and analysis are important Part.
At present, the wireless charging technology for electric vehicles is relatively mature, and the world's first wireless charging bus lane was built in Korea in 2013. On May 18, 2017, Qualcomm has already achieved the goal of wireless Charge.
Li Wu said that foreign companies with wireless charging technology have been in contact with their own initiative, the two sides are negotiating cooperation.The company plans to achieve high-speed photovoltaic wireless charging within 3 years.He said that the high-speed photovoltaic set aside the electromagnetic induction coil, with the future of electric Car wireless technology package, enabling electric vehicles to exercise while charging .At that time, the highway will completely subvert the traditional thinking, transformed into a huge charging pile.
However, each disruptive new technology is often faced with the cost of high-cost problems encountered by large-scale, market-based obstacles in 2016 in France, the world's first solar cell road 1 kilometer cost up to 5 million euros in the photovoltaic power plant in China 'One-kilometer road construction costs will be reduced by more than half of foreign', but even so, the cost of photovoltaic high-speed is still a lot of money, not to mention photovoltaic high-speed solar panels are also facing the inefficiency of industrial bottlenecks. '' If the traditional Is more unfair to PV than the cost of conventional freeways, the efficiency of traditional power plants, and the high speed of PV. "Li Wu has another algorithm for this cross-border disruptive project.
In the view of Li Wu, the PV high speed can avoid taking up a large amount of cultivated land and cause environmental pollution; it can greatly save the cost of power transmission and make it possible to electrify the highway; and solve the problem that the weight of electric vehicle battery accounts for about 60-70% ), High cost (about 80%), short life span (two to three years), charging difficult and heavy pollution, and promote the overall development of the industry. With the intelligent application of big data and information technology, driverless , Intelligent logistics will also greatly speed up.Wu Wu pointed out that with the development of photovoltaic industry, high cost, low efficiency and other industrial problems gradually resolved, photovoltaic high-speed compound social benefits will gradually be demonstrated.
Professor Zhang Hongchao of Tongji University believes that once the energy and information interaction between photovoltaic pavement and intelligent vehicles are realized, it is bound to change the mode of future traffic and promote the full upgrading and upgrading of transportation industry, information industry and automobile industry. The resulting equipment manufacturing, intelligent transportation And other emerging industries, will affect every vehicle user.
