When the 'solar + mobile wireless charging + driverless smart car' three high-tech superimposed fusion, what kind of scenario would it be? The sun-driven unmanned electric vehicle charges while driving on the road, maybe Many people are in the scene of science fiction movies. But now in Shaoxing, Zhejiang, China, the world's first 'three in one' super road has emerged.
On September 26, the photovoltaic road + mobile wireless charging + driverless smart car 'three in one' super road project held a results conference in Shaoxing, Zhejiang. From industry associations, experts and scholars, government departments and media representatives Nearly 100 people attended.
The prototype of the 'three-in-one' super road demonstration section is located in the factory area of Shaoxing Lanting Solar Technology Co., Ltd., with a total length of 98 meters, a width of 3.75 meters and a total area of 367.5 square meters. When the driverless electric vehicle starts, it shines in the sun. Next, slowly move forward on the solar road. This project is jointly developed by Lanting Construction Group and Zhejiang Lanting Solar Technology Co., Ltd., Ningbo Institute of Materials Technology and Engineering, Tsinghua University Smart City and Smart Transportation Research Center, Tianjin University of Technology, etc. After 10 years of joint research and development, the company has recently broken through a series of key technical problems and achieved phased results. It integrates photovoltaic power generation, wireless intelligent vehicle wireless charging, winterized ice and snow and intelligent transportation technology, covering multi-disciplines of composite and crossover. Field. It is one of the series of in-depth developments based on the 'Sun 1' heavy-duty test road developed by the group in June 2017. It contains more than a dozen key technologies and supporting equipment technologies, including photovoltaics. Electricity storage, waterproof and moisture-proof between road layers, radiation protection for wireless charging, shielding technology, intelligent identification of unmanned electric vehicles, etc. .
Li Jingxuan, general manager of Shaoxing Lanting Solar Technology Co., Ltd. said: 'The first solar photovoltaic pavement test technology of the 'Sun No.1' has a transparent protective layer with a light transmittance of 85%. The friction coefficient is higher than that of the traditional asphalt pavement. , Hard, anti-sliding high-strength materials, which can protect internal PV modules while meeting driving safety requirements; 'Solar One' photovoltaic pavement complete technology combines a series of technologies such as heavy-duty roads, non-load-bearing and light pavement structures. According to different road grades and different road use conditions, a variety of stable layers, a variety of load-bearing layers, a variety of photovoltaic functional layers and a variety of protective surface wear anti-slip layer, so that the road has sufficient chemical stability, aging resistance , high temperature and low temperature resistance.
The solar power is passed through a wireless electromagnetic induction coil embedded under the road surface, and is received by the bottom receiving coil of the driverless intelligent electric vehicle to generate a current, charge the vehicle battery or directly drive the vehicle, and the vehicle is charged while driving on the road. Currently, There are three main charging methods for electric vehicles: charging with charging piles, static wireless charging and dynamic mobile wireless charging, that is, charging mode while walking, no doubt, the last one is the most ideal charging method.
At present, the form of power generation for tiling PV modules under the road surface is not the optimal way of solar power generation efficiency. The purpose of the research is to cut in from the most difficult part, and combine with wireless charging and unmanned driving to explore the 'three in one' application scene and technology. The law of maximizing economics can be applied in demonstrations such as tourist attractions, large squares, closed roads, surrounding islands and reefs, landscape roads, etc. With the advancement of science, through continuous innovation and meticulous scientific design, the future It may be widely used on the expressway. In the future, the application forms of the three technologies will be changed or expanded. For example, installing PV modules on the guardrails on both sides of the expressway is also an option to increase the amount of photovoltaic power generation.
Solar roads are not new things at home and abroad, they are also conceptual products. There is no precedent for 'three-in-one' technology integration, and there are also problems in every aspect that have been criticized. But this kind of imagination, with science, A rigorous and serious attitude to actively explore new technologies for smart travel is worthy of recognition. Therefore, although this project is still not technically economical, its scientific and technological demonstration significance is far greater than the significance of practical application. More than 100 years ago, the Wright brothers invented the first aircraft' "Flighter 1", now seems primitive and naive, but on the basis of such a prototype, human beings have created a high-tech large plane that is free to soar in the blue sky in the process of scientific progress and iteration. The same is true of the wisdom of a dream like a super road.
